If my primary is private will my msgs get repeated or will I repeat others?
(Without the override freq thing)
only if 1) you're on channel 20 (906.875), 2) you don't configure it to not repeat
frequency is determined by primary channel, so you must override if you want others (strangers) to repeat
ok, so what I was asking IS possible, but with all 3 channels sharing the bandwidth, by using separate keys?
indeed
đŻ
Ah
Ok
I was doing it all wrong
So my nodes were in their own universe
And didnât get repeated or repeated anything
Like an island?
@toxic kindle what's your node names again ? đ
My personal nodes are my last name followed by a number
The club nodes are Wilcox followed by a number
ah I see. I guess I haven't seen any of those then
oh wait, I don't know your last name 
Youâve seen the email
its too difficult to pronounce
@blazing swallow I see you have piggybacked your own encrypted channel on top of public channel 
How does that work?
If those are encrypted msgs how are you decrypting them?
those are not encrypted (other than default encryption)
non-decryptable packets are "encrypted"
one day I shall have collected enough packets to crack 'em all! bwahaha 
hopefully quantum computers for the regular consumer are obtainable before I expire
If itâs a ham guy you can decrypt by knowing they say their callsign every 10 min and say the phrases 73, and cq a lot
--... ...--

I think you are referring to a setup which uses two nodes (1 on default frequency and second on a different frequency) which are then connected together using a local MQTT setup to share messages. This bridges between the two networks.
@sleek wraith @blazing pine
Hello Benjamin,
I was playing around with a Lilygo T-Beam V1.1 and the Meshastic 2.2.15 firmware for a bit. After a full week of running my node outside in a weather proof enclosure, my node never heard another node. I then started to research this and another HAM had a node up on San Bruno Mountain for quarters if not months and had almost no users so he took it down. I'm not against the idea if trying but I don't know if we will have much luck.
What are you proposing here? Which specific hardware are you thinking of using, what antenna (stock, external / higher gain antenna, etc? Are you thinking of just an RF repeater or an Internet gateway? You mention this would be solar powered but what would this power design be as it would also need to include batteries, charge controllers, and their location?
I saw that San Bruno MTN node for months! ed96d9d4,3,SBMt,KN6PLV SanBrunoMtn
the problem was it was in ham mode, and only 1 other node (from what I could see) in Berkeley was running unencrypted
in your reply, be sure to mention the default encrypted channel has a lot more users and is not limited to just hams
Imma need yâall to help me make a response
I didnât know I would get this far
And I have no experience building solar setups
also: external antenna, repeater/router, power self-contained with only "external" parts being antenna and maybe solar panel, but all one unit
mention using rak and how it sips power compared to the esp32 in t-beam and friends
Iâll get a response sent off by 3pm today
Also gonna include a LOS map from black mountain
I'm here for gramma đ” checks if you need 
Also we will need to figure out logistics
If anyone has a extra rak unit that would be helpful
Cause shipping takes like 10 years from China
Also for the response @blazing pine can you give me a estimate of the amount of nodes in the bay
Of an estimate of how many the black mountain node will reach
#1197026438805725264 message just show him this, collected by OHR with a little rak node with stock t-beam antenna...
and there are a lot more nodes still unseen
Some input here.
"if you build it they will come" 
- solar is nice but the temperature issues (low temps) wreak havoc on the current 18650 cells available. Ask if power is available. These things only use a USB connection so the draw is nothing. It would be better to run a USB cable for power and upgrades (see next line)
- firmware upgrades are a must. RAKs do have OTA but I've had failures with that process the last couple of revisions. You don't want to have to climb anything to do upgrades. A USB (with waterproof connection) lead to the node is almost a must.
- I've got a spare rack and a 9db antenna I'd be happy to donate to the cause.
that would be one loooooong USB lead
Depends on the location of course. If it was on somewhere like Monument of Chual; that wouldn't work out too well
I'd rather piggyback another esp32 to it just for power control (remote reset) and firmware updates over wifi
That'd work. Beyond my experience though
the software would take a while to develop and debug though đ«
(ignorance speaking) What power options are available at the location in question?
I am so totally wondering how long a node can run on a small ultracapacitor bank
Or would it be better to house the node is a sheltered area (building with power and won't freeze), run a long cable to the antenna, and put an amplifier in between adjusted to an output no greater that 30db PEP?
you would need receive amp too. much complimicated
Yeah, probably right. I'm lacking in the whole cable length loss calculation thingg
The San Bruno node is encouraging. In a separate message, maybe encouraging the owner of that node to put it back up but with the default channel enabled, as @blazing pine points out.
fascinating
but can't find where to buy
Little on the big side, but workable. I'm not sure what charge controller to match it with though.
probably no controller needed
just stock rak stuff
https://a.co/d/0yAjtDI big chungus
can probably run a rak for a few days
cheap enough, but still big chungus. and only 2.85v
Yeah
Imma prolly also ask I can invite him to the discord
hold on lemme delete some incriminating messages first 
Cause Email takes longer to talk in
Well I could either, Discord, Phone, Or on some Ham repeater
how about on... WW6BAY 
yeah
@blazing pine
"How to reach me:
Voice wise, you can find me monitoring the WW6BAY Bay-Net repeater system (145.390-pl88.5 or 433.975+pl100.0). Digital wise, you can chat or leave a message on 1200 packet on 145.050 via the LPRC3 node up on the Loma Prieta mountain top. "
His QRZ page
Imma reach ot after I send the email
over the radio
Neither could I. Looks like something a small consumer won't see for a while
Would be a lot better
@blazing pine Just using a preset someone made for the peak of black mountain
Black Mountain
K6OTR 441.85 MHz+ CC1 above Palo Alto, Monte Bello Ridge, elevation 2812 ft, 37.320348 N -122.142594 W ÂŻ_(ă)_/ÂŻ
wow that's like 45 degrees
so I guess it depends on the antenna
just go take a hike; fly a kite 
Its the WW6BAY site
If we get black mountain then we should then get their east bay site
Bro
This is actually so hype
Whole bay coverage
Plan is that we assemble a node to put up on Black Mountain
Well if the guy allows it
He was saying he heard another ham operator putting a node up
he said he got a t beam but was using it like a client device
Prolly also in ham mode
#1197026438805725264 message
I think Lora Short said he had a spare antenna and RAK
Idk about the antenna bc it is 9dbi but the RAK will prolly what we would base the build on
@blazing pine Have you seen a node with KI6ZHD?
doesn't sound familiar đ
Thatâs the callsign of the guy
probably too far
I think we should use a lower gain antenna
someone fire up the simulator
I have a sim but Iâll do it a little later
Iâm also thinking about logistics
bbl, time to get up and forage for breakfast
Who is gonna assemble it
And when and how will we deploy. It
Thinking if we could have the first in person Meshtastic meeting lol
Donât know how
Donât know where
Or when
But we could get everyone on the same page and assemble the node
Or just give the supplies to one guy and they assemble it
Can the WisBlock w/out the GPS module still send GPS data to recipients via the Android app? It looks it's supported on iPhone.
yes
Must be pizza involved......
I got bored and decided to write a response. @sleek wraith @remote vale @blazing pine If yall wanna take a look before I click send
Hello David,
I may have some information on why your node was not able to reach any other node. It may have been due to the node being set in HAM mode or the primary channel not being the default public channel. I asked around about the San Bruno Meshtastic repeater and turns out it was not reaching anything because it was set in Ham mode and only one other node was able to talk to it because it was set in this mode. There are a lot of nodes out in the bay but most are using  âLong Fastâ with the encryption key âAQ==â as the Primary channel. If you could pass this info on to the HAM who had the San Bruno node up that would be great.
The hardware for the repeater that would go on Black Mountain would be a Meshtastic Wizblock, which is a small, modular, and extremely power-efficient Meshtastic board. The antenna would be a larger 3 or 4 dbi antenna. There would be 2-6 batteries in the unit and the Wizblock has a built-in charge controller. I cannot say exactly what the design would be as I am collaborating with other Meshtastic users on this but it would be something along the lines of https://www.youtube.com/watch?v=_h3UluaqfTw.
By setting up this repeater you would enable Meshtastic communications across most of the South Bay. Lots of locally based repeaters exist already but a mountain repeater would help link it all together.
Here is the build video of the new 2024 version of my previous Meshtastic Off-Grid Solar Build I made a video on about 7 months ago. This new version has improvements over the previous version that make this one cheaper, easier, and more capable. Please see the complete parts list below if you would like to build one for yourself!

Really would be ideal to know what resources are available. Maybe an ethernet cable? Would be good for POE. How high will it be up? How to address a hardware failure, as in does someone have to climb to pull the thing for physical reset/plug into.
oh
I need to add that on to my email
@remote vale This improved?
The hardware for the repeater that would go on Black Mountain would be a Meshtastic Wizblock, which is a small, modular, and extremely power-efficient Meshtastic board. The antenna would be a larger 3 or 4 dbi antenna. Solar power would be the easiest to get going but if there available power we could also power the unit using USB or Power over Ethernet. This would not be connected to the internet so it would just be a regular repeater. There would be 2-6 batteries in the unit and the Wizblock has a built-in charge controller. I cannot say exactly what the design would be as I am collaborating with other Meshtastic users on this but it would be something along the lines of https://www.youtube.com/watch?v=_h3UluaqfTw. Also if the unit fails or an update is required I (or some other person) would need physical access to the node.

yeah
Amazing email put together by @remote vale
Good to hear you gave a try with your T-beam. While you didnât see any activity, it could be for a few common factors; Channel 0 (Primary Channel) renamed from LongFast which causes Meshtastic to use a frequency channel other than 20, no channels named âLongFastâ with a default encryption key, HAM mode enabled, or just in a dead zone. As for the dead zone, we are hoping more participants and a few well-placed nodes can fix that problem.
I asked around about the San Bruno Meshtastic node and turns out it was not interacting with anything because it was set in Ham mode and only one other node was able to talk to it because it was set in this mode. There are a lot of nodes out in the bay but most are set with Channel 0 (Primary Channel) as âLongFastâ with the default encryption key (âAQ==â). If you could pass this info on to the HAM who had the San Bruno node, this may greatly increase the number of people who could use a node in such a great spot.
The hardware for the repeater that would go on Black Mountain would be a Meshtastic Wizblock, which is a small, modular, and extremely power-efficient Meshtastic board. Power usage is between 10-20mA, with a peak of 100mA (usually on boot). The antenna would be a larger 3 or 4 dbi antenna. Output power is about 23dB. Center frequency is 906.875Mhz, 125 bandwidth (Meshtastic default channel 20) The enclosure size likely will be in the range of 8.6Ă6.7Ă4.3. The remaining config varies on site conditions, which I would greatly appreciate some info on if this plan has potential.
Possible configs could include:
- Solar panel mounted on enclosure with 2-6 batteries in the enclosure
- POE, for power only
- 120AC to USB-C
- 5VDC power source
There is no need or plan to connect this to the internet (no MQTT) as it can cause problems if things get busy. This location would enable Meshtastic communications across most of the South Bay. Iâve seen many new nodes popping up each month since I starting exploring Meshtastic 3 months ago. Lots of locally based repeaters exist already but a mountain repeater would help link it all together.
If the plans get a go, it'll take a little time to build, config and test. I'd really like to avoid having to do a site visit for any fixes.
curse grammarly......
yeah
I forgot to do that
I can forward it but doesnt matter since you can see the email contents here
I will most definitly send an update about it
Mmmmmm, pizza đ€€
I love the monologue đ
look at the from= field
I hiked there once from the Montebello road up to Black Mountain. Nice views from up there!
You're right, it's a dialogue ^_^
I once hiked up to mission peak, but I wasn't into Meshtastic back then đ«
Parking is challenging, unless you know to get a permit in advance and unlock the gate to the off-road parking. AllTrails was pretty good at describing this process that I missed first time I went up there
If everything goes well we should have a node up there
And turns out Tae also has contacts with another guy with a repeater up there so if things donât go well with this guy we got a backup
@blazing pine @remote vale @sleek wraith
Hello Benjamin,
Please meet Tim Wilkinson KN6PLV who is the owner of the San Bruno Mountain Meshtasic node I mentioned before. I spoke to him about your email below and he replied:
Oh this is interesting. The node is still on site so maybe I can re-enable it and reconfigure it. Will be later today before I have a moment.
Maybe once reconfigured, that might be a step forward.
Strange since I donât have contact info for KN6PLV and his QRZ is empty
Also he didnât mention anything about black mountain
Ohh wait
He sent the email to me and Tim
bummer. i just powered down my node earlier
but i'll be receiving a new antenna today so i'll be throwing that on and powering it back up
I dont really know what to respond with
Im just gonna leave an email saying ways to contact me
thats not email
I can continue talking by Email or we can do it over Phone, Radio, or in person. My phone number is BLANK. Or if any of you have a Discord account you can join the Meshtastic local chat as we have Bay Area meshtastic collaboration going on there. https://discord.com/invite/ktMAKGBnBs. I would like to continue talking about the Black Mountain repeater (to help South Bay coverage) and talk with Tim about the East Bay San Bruno Mountain repeater.
Discord is the easiest way to communicate over voice, video, and text. Chat, hang out, and stay close with your friends and communities.
Is this a good message?
talking... email... 
?
nothing. looks good to me 
Sent off
Lets see if I get a quick response
Since I sent it like 20 min after getting a response
if they go on discord they'll have a hard time finding this chat, lol
I would prolly find them
47.575 miles đ
the San Bruno node was the only node I could receive indoors
all others needed to bounce off my 30ft pole 
Donât say it like that
On the LOS map it shows it gets South Bay but really patchy
Not for long
i ordered on the 20th... still no ship
@barren socket if you were looking at buying wizblocks
someone configured their range test module wrong. it's sending once every 30 minutes instead of once every 30 seconds 
also, I think it's been running for days
#1197026438805725264 message
Donât know if heâs turning it on today
Waiting for a response
@sleek wraith @blazing pine @remote vale
Removing Tim from this thread as Black Mountain is my site. The node I was running at home was definitely in HAM mode as.. I'm a HAM. I suppose disabling HAM mode and enabling encryption can be an option. Checking some next step details, I see some problems:
-
BayNet already has a 900Mhz analog repeater on 927.8625 with a -25Mhz RX offset. That puts its receive on 902.8625 which is realistically TOO close to your proposed 906.875Mhz frequency. I don't know what your referenced "125" bandwidth is but looking at https://meshtastic.org/docs/configuration/radio/lora/ , i have to guess this would be about 125Khz. I can check with some of my resources but I think this might be a deal breaker.
-
FCC transmission legality: a 23dbm transmitter + a 4dbi antenna is under the max 30dbm EIRP
-
Is the enclosure and antenna all in one weather proof, tower mountable enclosure?
-
Looking around, it looks like a 4dbi antenna would be about 1.2 feet tall. That could be accommodated on our short tower.
-
For power, we could consider 1) solar or 2) 120AC to either USB-C or PoE injector. For a solar panel, how large would it be? Optimal aiming it might not be possible though.
The LoRa config options are: Region, Modem Preset, Max Hops, Transmit Power, Bandwidth, Spread Factor, Coding Rate, Frequency Offset, Transmit Enabled, Channel Number, Ignore Incoming Array, Ignore MQTT, Override Duty Cycle Limit, SX126x RX Boosted Gain, and Override Frequency. LoRa config uses an admin message sending a Config.LoRa protobuf.
What I think is that the interference would not be an issue for the ham repeater but more of an issue for the Meshtastic repeater
Bc of the low power
nah, more of an issue for the ham repeater
I wanna know if other people have done this with meshtatsic and if they noticed interference
it might inject noise into the repeater because it's very close
if the repeater's tx and rx frequencies were reversed it would interfere with Meshtastic node ÂŻ_(ă)_/ÂŻ
BUT if you can somehow get the node as far as possible from ham tower it might not interfere too much.
it's pretty easy to check for interference though. just bring up a temporary node and check for noise on repeater ÂŻ_(ă)_/ÂŻ
I just asked on a ham radio discord about the interference
my Meshtastic node interferes with vhf receive on my radio 
Thatâs with lower quality radios
$600 receiver ÂŻ_(ă)_/ÂŻ
Repeaters I would assume have really good filtering
Oh
Whats the upper and lower frequency for channel 20? I don't see anywhere in the docs a spec on the measurement of bandwidth
it's LoRa. I guess 125khz as stated in the email? ÂŻ_(ă)_/ÂŻ
I'm guessing as well. Prefer not, unless it's craps
simple to check with an sdr
I found some docs, confirmed khz
Iâm gonna need a team of mesh scientist and Ham nerds to craft a response to this email
Given the power and spread spectrum, I'm unsure. Though it does not seem a likely conflict. It's going to be the hosts call on giving it a try.
Yeah
I have an SDR so I could try just broadcasting on public channel
Seeing if it bleeds into 902
try it at different distances
Science experiment time
I've seen some demos and the transmit looked pretty tidy.

The Semtech SX1262 should be pretty clean. It's definitely not a Baofeng bleeder.
Neat tools!
after further tests, i can conclude that it might not cause any problems as long as the antennas aren't right next to each other
it's my first time using this. i don't know how2sdr
i also have another $200 sdr that has a stupidly wide bandwidth, but i haven't really used that one either. derp.
You've got more than I.... x > 0
MOXON!
it's what i had laying around
Your host may benefit from a lower band test of the proposed device.
can confirm no noise on 902.8625 on this lil $200 icom receiver with node 2 inches away
INFO | 00:44:34 394194 [Router] Received text msg from=0x3e1c8f95, id=0x755f881a, msg=testing a very long message for a very big packet just to test a very long transmission to view on an sd
wait why did it chop my r
Nice. Which Lora chipset?
that 1262 or whatever it was
Heltec, SX1262 sounds right
ping from node in the sky to a t-beam ~5-6 feet away, and its reply
So distance does really matter
i selected 4194304 fft size and now my computer suffering xD
wow it's like 4 frames per second
it may be the cheapo sdr dongle i'm using... who knows
oh you mean that very bright blip?
it might be from some other source. i get those blips from time to time
and i hear it on my monitoring radio too
The thin line to the left of what looks like the response
ah, that's the ping (waterfall falls downward)
and that blip is indeed just some noise from another source
Ah, thanks for the orientation
@toxic kindle I would venture to guess this could help your prospective host with evaluating possible interference.
Wow
You used as many fancy words as possible in the sentence
probably not that specific screenshot. the "splatter" extends past the sdr's bandwidth range
but again, that may be due to cheapo sdr
i'd try my expensive one, but that requires compiling a list of dependency hells that i'd rather not suffer today
I just got a message from someone but they don't show up in my node list. How does that happen?
no nodeinfo
what was the message? :>
and who uses a t-deck anyways
I need $50000, lol jk its "Anyone out there?" and the node is !318ef2b8
@blazing pine
never seen that one đ
The cursor is on 902
Why am I getting interference still as seen on waterfall
splitter splatter, might it just be cheapo rtlsdr dongle?
yeah, looked like it in the screenshot xD
I can hear the interference noise when I send a msg on the Meshtastic node
i can't hear it on my expensive lil handheld icom with heterodyne receiver
Whatâs the verdict?
let me try one more test. i'll transmit a carrier on 902.8625
Scully?
i get major desense when holding radio less than 1 feet from node. slightly over 1 feet and it's nearly no effect
So I should tell him that if itâs more than one foot away from the receiver antenna it should be ok?
hold on there's more
when signal is very weak, desense can happen from 6-8 feet away
but this is all from within the radiation plane of the antenna (whatever that means)
i don't really consider myself a ham even though i have a license, so take what i say with a grain of salt 
... and it's also coming from an omni antenna. It may be worth exploring a ~220deg or so radiation pattern to the front (area of interest). Still looking like a possibility
Do you have some sdr screenshots that I could include in the email?
@blazing pine What should I say is a safe distance?
a couple feet or more below the 900mhz ham antenna
actually, let him decide đ
Can I send that
Was the node really 2 inches away?
... there was no noise on top of the white noise that was there 
(no lora-type noises)
-
I did a bit of testing and research and I don't think the node will interfere with the repeater. I tried out with an SDR and sending longer packets over Meshtastic and interference wasn't an issue as long as the node and receiver were not within a couple of feet of the antenna. Having the Meshtastic node antenna lower than the Repeater antenna would prevent any interference issues. With filtering on the repeater it would be negligible I think. But it is your call as I do not have experience making or maintaining ham radio repeaters.
Here is a picture of a long Meshtastic packet being transmitted and recorded using an SDR only 2 inches away from the node: -
The enclosure would be a waterproof box that would have the hardware to let it easily mount to a pole. the antenna would either be sticking right out of the enclosure or it could be wired to be a bit higher than the enclosure box.
-
PoE or USB-C would be ideal but solar could be used if that isn't available (I would imagine the site has backup power so it would keep charging). The solar panel that would work on a solar build would be something like this soshine panel (https://www.amazon.com/gp/product/B099RSLNZ4). I don't think optimal aiming would be required for a build like this but if we decide to go solar there would be a lot of testing done on it.
My Response
probably better to leave out the filtering bit đ
because... interference is interference 
That was the response I got from the ham radio discord
wait, the 2 inches thing was with an fm audio receiver, not sdr đ

it's an icom ic-r6, btw
one of the most easy to use radios ever, contrary to some reviews

I'm sure he wouldn't mind. The distance would surely eliminate problems if they occurred. It's very nice he's even considering.
I thought I would have to explain what meshtastic is but I think he knows more than me
Found out hes the leader of the ARDEN Mesh group in the whole bay area
ah I know that
with like 10k+ dollars invested in the system
Nice. I'm sure he'd be a great person to learn from.
Should I send?
@timid turret any input? đ
He asked for input on my response to an email
The response is in refrence to
Is that David, aka Duv?
David Ranch KI6ZHD
This would cover like 99% of the South Bay and a bit of East Bay
on Black Mountain, supposedly on same tower as a 902.8625 fm repeater
add to that email info on the device's RF power output and the antenna gain attached to the device.
We talked about antenna gain the the previus email
cool
I mentioned power output in the first email
Been using these smart people to help me respond to the emails
I dum-dum
How high up from the control room woudl this be?
Probably would be the next part of this email thread after I send this
Dont know yet
instead of mentioning usbc or poe, generalize it a bit more and just say 5v power @ 0.5A
it won't matter to you in what form it comes in.
solar would be good but you'd need to then come forward with the analysis data on proper sizing and battery storage required to maintain service in the worse case of heavy weather during the winter.
in that case, you'd expect a many days of nearly no sun
4x18650 dynamite pack with heater pad 
I would say USB-C is easiest to handle
But if anyone has a giant roll of Ethernet cord lying around then we would do POE
make it easy on yourself đ
I'd stay away from POE
noisy noise is noisy
that would imply switching regulators and switching regulators will add noise
I've got a bunch of outdoor rated. Depends on how fare up it goes
stay far far away from switching regulators.
for radio use, especially on a tower shared with others, only use linear regulators. be a nice neighbor.
usb-c power usually supplied by switchies 
I believe it was the owner who offered ac or poe
or USB..... (5v)
So should I remove POE from my response....?
if you use ac or poe, you'll end up doing a lot of signal anlysis before bringing it up to the tower to make sure the rails are clean.
solar most simple, except for batteries and temperatures
Wouldnt USBC be easiest?
Just plug it in and add some batteries
I have a feeling USB comes from AC dingle dongle
this is cool! for your thought experement ... imagine this is going to space.
once launched, you will have no access to it.
build to those specifications đ
build in a slumbering esp32 that will wake up when it's time to flash new firmwares
As many batts as can fit are going in
If the Site goes down we got like a year
and if batt goes derp you have much fireworks?
Test the batteries for internal resistance. Make sure they're within your spec.
ultracaps are cool
Independently fuse the batteries so if one fails, it won't take out the others
very unappealing discharge curve on ultracaps
Dont think I have the expertise to build something like this so the build would prolly be at someone else's house
hey, i like only being able to use 10% of my power source!
Should I send the email?
@toxic kindle Now that you've woken me up ... how much longer will you be around? i need to go walk the dogs but when i'm back, let's talk about open sauce.
anything i build will be suitable for #notabomb
Ill be available till 11 pm

Hi guys. Do you guys keep you batteries in a fireproof box when left unattended? 18650 cells are safer then Lipos but the size of the batteries we build for these e-foil board have enough power to burn several houses down! I see the most common build method is spot welding the cells. This is the easiest, and least labor intensive method but it...
cool. will dm you đ
for my next build i was planning on soldering 4 18650s together... not with wires but soldering the casing...

oh, for the love of everything perforated ... please don't solder 18650 batteries
extra solid!
i've soldered CR2032's before. no boom/pop/bang
just need very high temperature and nice acid flux
the damage is unseen and may result in fire down the line.
it's okay as long as it's 30 feet in the air and not in my hands or between my legs
too expensive for my retired butt
be careful đ
you got him going.......
i have a lincoln welder
I'm sure you put your Lincoln logs together with it. :p
linkin' 18650s
sigh, I miss my Syncrowave 350
i miss my long dingdongs for reaching nooks and crannies
when i see people welding i have the urge to ask them if i can have a go 
Makes two of us. Keep having to restrain myself from buying one of those TIG/MIG/Plasma cutter combos.
i cut with mig when i'm too lazy to set up the plasma for a 3 second cut 
If anyone here needs to weld anything. Please consider me an available resource.
My shop is available to anyone here
I have a multi process mig machine that can do aluminum and steel. Also have a 350 amp water cooled tig and a plasma cutter
burning man related? 
Basic necessities of a well stocked garage
It does get used for burning man, but was not purchased for burning man
i left all my big toys when i retired 
How long ago did you retire?
don't even remember. 3 years ago, maybe?
@toxic kindle Good chat! Like I said, now you know how to get my attention. đ
đ
Thank you, for the thought experiments as well
For power consumption on the tower⊠a repeater or router will use significantly more power than any other node. This is because the radio front end will be very busy and that uses a lot of go-juice.
100ma @ 5v a good budget? assuming a RAK board.
I would assume it would take us at least 2 and a half months to have a fully deployable node
We could start building it before we get approval since even if we dont get this site we will find another location
https://www.msesupplies.com/products/mse-pro-100-pcs-of-18650-cylinder-cell-case-with-anti-explosive-cap-and-insulation-o-ring fascinating. supplies for making fake batteries!

And after we finish the first we could have a template for other Bay Area Nodes
Li-Pol (LiPo) batteries are widely used in nearly all Cell phones and other home electronics. Yet, they are unstable and dangerous. In our test, we compare LiPo with available LFP and LTO technologies.
You may not recognize the danger of sitting in your pocket, but consider the danger for projects involving batteries and prevent future issues. ...

mmm spicy
@remote vale We are going to be submitting a exhibitor application for open sauce this year.
If you can add some improvements to the application before we submit it on Friday that would be great.
https://docs.google.com/document/d/1WRkSFoormcfNwsKh2eGCWi9C-TVR-NleCi5YD0K0WeI/edit#heading=h.a3kk772b2uio
Open Sauce is happening in SF this year and if we can get in we can boost Bay Area engagement in meshtastic and the project as a whole
I'll take a peak tomorrow. I was hoping to get time off to go, but looks like i'm working those days đŠ
It's making me think of what kind of sensor stuff to demo..... hmmmmmm
hottest/coldest spots in the exhibit area?
sensor count of people passing a node with motion sensor (unfortunately I've run into the buggy interference on the gighertz radar RAK sensor)
Position sensor stuff would be fun but don't think GPS would be reliable in there? Don't know though
Maybe custom MQTT feeding position data from another site where stuff is always moving around? That would be a fun map
I gotta stop or i'll never get to sleep.
Maybe a node with an I/O board visitors could control on a custom channel (QR code provided)? I haven't had the chance yet to experiment with those.
It's quite challenging to read a day worth of messages at a time đ
Can you share it with comments instead of just read-only?
Thanks!
Updated
is it a typo that the document is called "Mesthastic Open Sauce" - sauce - instead of source? đ
Thanks for the context!
@blazing pine Turns out the guy re-enabled the San Bruno Mountain Node but then it died
He said he will take a look at it when he goes up there
I took a look at the open sauce exhibitor application page. https://opensauce.live/exhibit-application/
Show off something cool you've built at Open Sauce 2024. Exhibitor booths are free for individuals, nonprofits, and open source projects..
Never have I ever seen questions like those..... hahaha
Sounds like a fun time
Edits made
New Email Alert @remote vale @blazing pine
Hello Benjamin,
Thank you for your notes on your testing. You mentioned this was tested using a "simulation of the proposed device". What does that mean? Every transmitter has unique characteristics and the real impact comes from the real antenna. In BayNet's setup, the master receiver antenna is on top of the tall tower where as potential mesh device would be down on the short tower so there would be some substantial vertical distance. The 900Mhz radio is also on a set of cavities but since the LORA transmitted frequency is in between the analog radio's TX and RX frequencies, it won't get blocked out. Regardless, I've asked some other people in the group on their thoughts here. The 900mhz side of the repeater is not used very much so we might be willing to accept some level of interference. Still waiting for a reply there.
For the enclosure mounting, can it accept being bolted to the side of a tower brace (aka.. NOT on a pole)?
When you say USB-C, what does that really mean? You're not really proposing some very long USB-C cable from the inside of the building, exit the building, go up the short tower and into the Meshtastic device. Also, how will this device be managed to troubleshoot any issues, upgrade the firmware, etc?
For your SDR capture, this looks like Gqrx. Correct? Which SDR hardware?
End of the email
@sleek wraith
I know updates cannot be pushed OTA so it would have to be mannually updated like at least once a year
updating via Bluetooth might be possible
Could you explain about the "Simulated device" and what SDR it is
just say cheap rtlsdr. but that screenshot certainly doesn't look like 2 inches away 
I was going off of what you said
so your node was 2 inches away from your sdr? đ
good that he didnt ask about that
This

@blazing pine For the proposed device should I just say you were using a WizBlock node and sending a test transmission on 902 as you said?
I believe @blazing pine was using a replay of a SX1262 based transmitter which is the same as the proposed unit. Of course, David is correct on the unique characteristics of the actual device. That'll be down the road a little. The preliminary test was conceptual.
As for the updates, that's what I've been concerned about. I've had more failures than successes with OTA updates. The only other option is to wire up the reset but and run it, power, and USB +/- in a cable to the building. Need total length for testing. If this works, any updates would be from the building.
As for mounting, I'm sure we can make anything work. Just need to know what the size of the framing, method or bolt pattern is to make an adapter plate.
for the "simulation", icom ic-r6 acts as repeater input. a signal generator at some distance acts as a repeater user, generating a carrier. a Meshtastic node with an sx1262 is placed at various positions near the receiver and is pinged to elicit a transmission from it.
đ
This is what he said "You're not really proposing some very long USB-C cable from the inside of the building, exit the building, go up the short tower and into the Meshtastic device. " it might be because of how long the cable will need to be.
you failed to mention usb-c will be power only đ
BUT usb-c with data may be useful
I wonder how feasible it'll be to have a cable hanging off the node where it can be accessed easily
Only two ways I know to update a RAK board, OTA and USB-C with access to the reset button.
Sat image of repeater site for context
how about both? Bluetooth to put device into update mode, USB to copy firmware đ
but reset button more reliable
Is that possible? If so, works for me
the newer bigger rak solar enclosure has a waterproof connector
m8 5-pin
gnd 5v data+ data- reset
anyways, time to go back to sleep. gute nacht!
Are you nocturnal?
lol
@remote vale I think I have most of the response worked out but the part about the usb c
Sounds like he thinks its a dumb idea
The idea is a 5vdc source. As for a long USB wire, I'm not in love with it either. But there aren't many choices.
Something like this has the cable fixed but we would need at least a 10 ft long cable
https://store.rakwireless.com/products/wisblock-power-supply
Description Power your WisBlock IoT solution with this powerful and reliable USB Type C power supply. Designed for WisBlock, this power supply can be used with the WisBlock Base Boards RAK19001, RAK19003 and RAK19007. It fits as well with the WisBlock Power Modules RAK19012 and RAK19014. Itâs 1.2m long cable with the U
As @blazing pine eludes, it would be a 5 wire cable from the node to the building carrying 5vdc and low voltage data lines
Don't worry about length and power supplies. Those can all be made and altered
the data part doesn't really have to go into the building. it just needs to be accessible without climbing
if we go Solar will data cables still be needed for updates or could OTA work
If we need to run power, might as well put it all in the same place
yup
that's why solar isn't really worth it here
solar is easy clean power though
No climb is the goal
Also I will mention that settings will be changed over the admin channel
And the status will be monitored through other nodes
I think we could also set up a sort of discord bot later on to ping everyone if the node goes down or it loses significant battery (Not important rn but a cool idea)
best to address his concerns and leave the extras out đ
My OTA experience has been more failures than sucess, especially the last couple of updates. If it fails, it bricks the board and you must have physical access to reset and update.
Yep, important thing is updates through some sort of data wiring and setting changing through admin channel
wired also allows the bluetooth to be shut off
Also one more thing is that repeater owners like to keep their sites secure so he may want to be the only one to set this up and he may want to be the only who updates it to not let others into the site.
Batt saving đ
Noise saving and reduced ability to hack
except wired introduces many times more noise than Bluetooth đ
You win some you lose some
You think with a shielded, twisted pair?
you can probably test this out with a battery powered node you have handy. compare SNR readings unplugged and while charging
noise comes from 5v power source
As MC Hamster pointed out, it takes a good linear power supply to help reduce that
Before we deploy anything it needs to be checked by the one and only Mc hamster
how about this: node and antenna on tower, access box with batteries and solar panel and USB at the bottom
put as many batteries as you desire, lol
add one of them USB repeater things somewhere in between
May not be needed if site already has power backup. We are talking somewhere like sub .05 watts
I would want at least like 1 battery as the case will have more than enough space to fit them. Also cannot go wrong with extra backup
Since we would want something like this to withstand in the event of an emergency
battery will have to be able to handle low temperatures
That's the challenge..... My experiment on that failed. I moved it to constant power and backed up the power source instead
Gotta run all, crashed server awaits me.
Idk how much heat the board produces but in a enclosed case would that be able to protect it?
definitely not
maybe if you add in a light bulb... which will promptly cause a meltdown in summer
hahaha... easy bake oven style
I used the Rak VisBlocks, although which variety I dont recall. I have a second device in the basement so what Iâll probably do is update that and configure is appropriately, then switch it out with the failed one at San Bruno Mtn. Two man job to replace it on the tower though, so might be a few weeks before I can get that done.
Thanks
Tim
Depends on what you want the updates for. The core of the functionality doesn't change.
Keeping the device up to date would be good
Find a stable version and stick to it.
As a repeater or router, there are very minor changes. That part of the code is extremely stable.
I was thinking a bit about issues with bandwidth and I think that could be helped with creating a protocol for people to follow so we dont end up in those scenarios. Like leaving breaks in between replying to a message in a conversation or in a emergency avoiding texting all together unless it is necessary to facilitate emergency traffic
anything that requires social enforcement will break. the underling protocol and algorithms are already pretty good.
i think we need to be very careful. we can't stop meshtastic from being used in an emergency deployment but none of what we have is certified to work in an emergency. please be very careful when setting expectations.
if there's a fundamental changes required for any 'sos' type change, an rfc should be created for the proposa.
i think that can be done without any fundamental breaking change.s
Yeah
But within just the meshtastic discord bay area group we could start doing that
I â€ïž experements !
And was thinking when we get full coverage we can schedule a test at a specific time and everyone tries sending messages at the same time and seeing what goes through in such a busy scenario
No need to involve others in that. It's easy to create this kind of traffic.
At least sending out messages a day and an hour before the test to let people know that the test will take place
yup
how much of the bay (the water area) would be covered by this?
i know someone who was talking about building a meshtastic network for kayakers. there could be synergy here
San Bruno Node
Black Mountain
Those are both in the works and not deployed yet
The San Bruno Mountain node owner is going to be setting it up in about 2 weeks since he has to get someone else to help him climb the tower.
@toxic kindle what link budget is that setup for?
The default I would assume
@timid turret Should I tell him to set a specific setting
could you try wiith a link budget of 145db?
How can that be changed?
it should be in the software that created those maps
Thats just an LOS map
oh, then that's not representative
one moment ... i'll get you a link to the software
I think I know what you are talking about
Ive used it before
@timid turret When he nstalls the node will he need to chnage the link budget?
the link budget is part of the equation that determines if two devices can talk to each other
included in the equation is any losses from cables, gains from antennas, efficiency of amplifiers ...
see the table here:
https://meshtastic.org/docs/overview/radio-settings/#presets
Maximize your Meshtastic device's potential with detailed radio settings instructions, including frequency bands, data rates, and encryption options.
ah
i calculated those link budgets based on regular antennas with no gain
You confused me a little
the link budget there is the minimum signal required for two deivces to communicate
your goal is to be above that number
@timid turret Relating to our previus discussion #meshtastic-on-www message
maybe make up a list of guidelines.
- If your EDC node can see a router/repeater in range, you don't need your own router/repeater
- Increase position broadcast interval to 1 hour (3600 seconds) or longer for stationary nodes
If there are any guidelines that suggest something different from our defaults, they should be evaluated to make sure that the guidelines are correct and if so, the defaults should be changed.
We should be easy enough to use where settings don't need to be touched. Super Geeks always want to change them and our problem reports go up.
did the meshtastic team ever get access to the ukraine mesh? đ
they publiushed connection information on their website
they have a site?!? 
yup
WIKI ĐŁĐșŃаŃĐœŃŃĐșĐŸŃ ŃĐżŃĐ»ŃĐœĐŸŃĐž ĐŒĐ”ŃĐ”Đ¶Ń Meshtastic
that's another one, not the one i remember seeing
oh đ
the guy importing the hardware for Ukraine was on our discord some time back
Ah
Every hour
A little too long for my use case
I would go with like 10 min for myself
But there is an overdide
So even if no movement it still sends
and if there's no movement you probably don't need to send at all 
anyone who needs your latest precise position can just send a position request
But something like what Ukraine has with some settings for people to set up nodes would be good
Not like we are forcing other people but it would be easier so they dont have to go on a deep dive to determine what settings work best
And so the mesh doesnât explode
But thatâs when we get the mountain repeaters up
i'm more worried about node imploding than mesh exploding xD
maybe there ought to be a spare or two
2 devices in one enclosure. add a switch. hang a long "pull to activate" string.
Thatâs Tim
@blazing pine what location
Also try sending him a message
no position yet, but I think I'm receiving directly
Prolly not at the peak I would think
node first seen <t:1693306366:R>
He said he would wait till installing it
oh what great timing. I just went out of range of bluetooth
@sleek wraith you seeing anything?
his node went up almost 3 hours ago
oh wait I'm not getting his node directly. there's one in between đ«
I'd do a traceroute if it didn't fail like 95% of the time
I might be receiving his node through one of @sharp mantle's
He prolly is just testing the node at his house
If it was on the mountain I think everyone would get it
i did. it may or may not have gone through
oooh so THAT was him. berkeley
so that wasn't another ham connecting to the san bruno mtn node back then. it was himself 
The node from which you got the node info about the San Bruno mtn node?
i used to receive d3bd,KN6PLV Berkeley from SBMt,KN6PLV SanBrunoMtn
but now he's changed his name to callsign only
i have a dinky little Heltec V3 WSnotL connected to a server in the basement. with a humongus ugly bash script to scrape the serial debug log live
i'm scared to upgrade firmware and bork everything
neighborinfo packets confuse it 
i had been meaning to write a bluetooth version to connect directly to my rak in the sky, but i computer illiterate
plus my bluetooth/wifi module died in my computer and i had to rip it out đ«
i'm looking through my 600+ lines of nearly-readable bash right now 
biggest mumble of jumble i've written
micropython is okay. regular python is much bad
Use Java
i don't like simple scripts taking 3+ seconds to start
i failed java in university. that's how much i hate it
sure, i'll do toilet paper code, but i'm gonna make you work to decode it!
First language I learned
If a language isnât similar to Java syntax I refuse to learn it
i used to be PHP god :>
i'd port all sorts of C crap over
Like Js and C++ are really similar and I picked them up quick
I want to figure out if I can control a Meshtastic device through serial or Bluetooth using Java
Bc I refuse to use python
I know thereâs a library for doing that in python
oooh, i have uncompleted stuff here. apparently i estimate "lost" packets from nodes
had to pull some voodoo there because bluetooth protobuf packets incremented the node's packet counter too. derp
BUT as a result of that voodoo i could also "guess" whether or not a phone was connected to a node
this can be viewed as oooh neat undocumented feature or... OH NOES PRIVACY VIOLATION
so there was a time when i logged all the times @sharp mantle connected and disconnected from his node 
@sleek wraith can you check your purple node
Oh sorry I confused you two
@barren socket is testing with a T Beam and he said he sees your node
Is it Sutcliff?
Nope, it's Meshtastic 9d34 and Orange - 3d00.
@remote vale
I sent you a DM around 8pm last night
bummer, but it's showing a checkbox in the cloud, so doesn't that mean it was successful???
For a direct message, no. Just means some picked it up
ahhh ok, yeah maybe it was the 2nd node inside my house at a 2nd story window. đŠ
good to know, thanks.
Sounds like you see the Purple?
Can you see the nodes off Montevina?
not sure which one that is. I see:
Cupertino Hogwarts, Cupertino Snape, Purple, Discone, AbelDog, Floor, Meshtastic 9470, BlueMoon, and Meshtastic 8b47
Abeldog, BlueMoon, Floor, Discon and I think 8b47 are all up there
how do I find the ID? (such a newb)
maps shows me its south of Reid Hillview Airport. đ
21.5km from me but don't know how to find its ID
With a T Beam, about how far should the bluetooth reach to my phone? I'm used to getting around 20-30ft for BT earbuds in my house, but only getting half of that with the T Beam. I hope the RAK Wisblocks we'll be ordering will be sufficient for when they go on top of a mast on our 2 story roof, which will make them further than now.
And I was using the 2nd node inside the house as a relay for my msgs to get out to the mesh via the one sitting on the window sill on the 2nd floor. So does that mean that msgs sent from the window sill's phone will also give me a false sense that my msg got out, b/c the check mark was shown just because the downstairs on got the message? So that check mark is actually unreliable in the way I'm using it? I'm doubtful that my BT, even with 20-30 ft range will reach a node at the very peak of my roof, let alone if I put it on a mast.
hence why I'm using 2 nodes inside the house
I see the ID's in the desktpo app, not in the phone app. You found my purple!
For me, the RAK BLE works fine from ground floor and into my attic
it may work.
who owns 82c4? đ
last seen 2 hours ago. no location. probably in repeater mode?
my meshability just got waaaay better
neat
Your log files are going to grow
only 117MB so far.... for this session
Ok, but we have 2 stories, so just have to try it. But if it doesn't, and since I shouldn't have 2 nodes in the house, just always have to go upstairs to get vertically closer to the BT in the node?
@remote vale do you have a repeater in your attic?
@blazing pine can you pls post one of your colorful logs of the nodes you saw today?
Could always put a bigger BLE antenna đ
Box is in the attic, cable to antenna nearby
oh wait, yes, the one on the roof will be set up as a repeater. It's currently not, so maybe that's why I'm getting those "false checkmarks?" Right now, they're both as just nodes.
Iâm thinking of putting a repeater in my attic bc then I donât have to deal with drilling into my roof plus cabling is shorter
And it doesnât have to be waterproof

Our estimation would a cable run of 50ft from power source to Meshastic node. Considering that Meshtasic nodes get their firmware upgraded via USB, that seems to be what is really needed. Do you know what other sites do to support 50ft of USB cable for useful power delivery and firmware updating?
Been talking with people in #960633667749822564 and I think we might need to go back to POE
Probably be something like the node tells the node that it wants to update to switch frequencies and when they both switch frequencies it starts updating
Since we donât want it updating and taking up the entire default freq
it would probably never happen. not enough storage
you would need another device connected to assist
Next Friday (March 8th) I will be doing a Meshtastic introduction activity with some nodes after school. From the school we have a good line of sight of Mt Umunhum. I was thinking that if anyone could go up there starting from 4 pm it would be cool having the students text extremely far with these small units.
Mt Umunhum is accessible by car all the way to the peak
that's no fun đ
unfortunately i still don't have a motorcycle helmet after my little oopsie last year xD
hi friends... fired up my t-beam in berkeley the other day, but I live in a pseudo faraday cage. Took a trip to SF yesterday, but only got intermittent pings to nodes.
@blazing pine may have gotten you. He has full coverage of that area
time range?
and node name đ
VDBX ...over the last couple days it's been in and out of my bus. had it on the roof a couple days ago and it saw maybe 5 nodes. my trip to sf was like 3-6 ish yesterday.
thinking about putting an external antenna on my bus and keeping it solar powered and then getting a tdeck to keep on me
not a single hit 
i also may have mixed the oe antenna with my other lte and wifi antennas.
here's all the nodes i've ever seen with their last positions
colored by hops. lower usually means farther
my skynode is off right now, so unless the ISS casts its holy shadow upon my node's solar panel it's unlikely to revive until tomorrow morning
Is it the issue where if the node dies it canât come back?
i've encountered that once... but i hope this isn't the second time, lol
i had shut it down manually
Is there a way to fix the issue?
#random message
(bigger battery)
also, that battery just finished charging
I mean a actual solution
Like maybe a separate device just to turn it back on
or just a timer circuit to reset the dang thing once every 24 hours
bring a radio/sdr for some visualization of them meshy packets
Maybe
hey everyone, I'm based in SF and have a few friends that are getting repeaters and nodes in places. would be great to connect with other folks in the area!
is anyone organizing irl get togethers in the bay?
May be coming soon
Would be good to build some repeaters together
yeah that would be awesome
@blazing pine So I decided the repeater will be POE but if theres also a battery in it and lets say the node somehow dies and turns off, is there a way to turn the node back on without climbing it?
apply power
Would the unplug and replug still work with batteries involved?
I assumed you meant batteries died
yeah
otherwise it's not usual for a rak node to power off on its own
Sounds good
I dont think it gets to freezing in they bay so temp for batts might not be an issue
mountaintops be cold
Between the range of -20 to +50°C (-4°F to + 122°F) is sufficient but the most optimal storage temperature is somewhere around 77°F or 25°C. If you are planning on storing your batteries over a long period of time, it is actually better to have them charged at around 50% rather than 100%.
that's storage, not usage
18650 cells are rated normally at between 20 and 25 degrees Celcius.
Any deviation from this will create a slight loss in efficiency. A 10-degree deviation might account for a loss of 20, or 30mAh.
While the extremes, below zero, or above 70 degrees, will see much faster cell degradation.
Using a cell at suboptimal temperatures will decrease its cycle life.
Tip: Never charge your 18650 cell below freezing! Eg. in a garage in Winter as it will degrade particularly quick this way
While you are using your cell, if you notice it gets hot, let it rest. Under normaly use your cell should not get hot-to-touch, and should never exceed 60 degrees. If it is getting hot fast, you are over-stressing it.
that. below freezing.
hmm im thinking we should put a weather sensor on the board for the repeater
The temp would be the inside but the air quality and barometer would be useful
@blazing pine thinking we can use a POE injector that has backup power in it so we donât have to deal with 18650s on the build
And since if the cable disconnects there will be no redundancy I would want to use a thicker cable and tie it down so it doesnât sway around
mptt poe injector? đ
?
I have a battery backup powering all my wifi access points over poe
so uh... have you set a budget yet?
I will probably buy most of the stuff except for the Wisblock since Lora Short has one
So budget would be like 100 bucks for everything thatâs not the module
that's... suspiciously low
Idk
The stuff is relatively cheap
Budget more like 200
Have not began taking prices
I'll donate a paltry $20 for each node that goes up. maybe others can chip in too đ
needs moar industrial strength materials
Iâm prolly not putting a node up on my house so the budget that would go to that is going to this
Ok well
Heading off to the paara meeting
Where I will see @simple hedge
Not if there is a battery keeping it partially on.
Got all my nodes with me
to the moon?
For budget, let's see how this first unit performs. I've already bought the case and a bulkhead connector. I'll do some testing with USB on a 50ft lead next week (kind of curious). POE should work too, but I don't have that extra RAK hardware on hand. I'm not worried about cost all that much as I look at it more as a hobby to tinker with right now.
Hey Bay Area friends!
Been busy in the lab this week and boy have I missed a lot! Very excited to see the mesh getting going strong here
I have some funds to donate too!
not to mention if anyone needs some hardware I have a few RAK boards to spare
Very kind, thank you.
I gotta catch up on the messages here about these potential tower site plans but if there is still a plan for solar I have been testing several setups here and back on the east coast for about a year on and off now, including a LTO build, and would be happy to share some input or equipment too. I have a nice sunpower 5W panel to spare at the moment
I also have a pile of WSL and Heltec V3s if anyone wants to hand out to local frens. I am finally printing up cases for all my T-beams to evangelize to my labmates lol
At least for the Black Mountain site, solar doesn't sound like it'll be practical (aiming for no-climb for maintenance and firmware flash, not ideal positioning for a panel and mounting will be lower on the tower). Maybe another site down the line?
Totally, if there is 5V or AC available there is no point to solar!
solar = clean noise-free power
why am I thinking of the name tim
one of the messages I saw seemed like access after placement was unlikely
I get the impression it may be limited. It's at the generous host's discretion.
IF these sites remain friendly, it would be very cool to be able to upgrade the tower sites to a node with the Ebyte E22-900M30S module for 1W capability
I am waiting on a package from china to test out a build with a nRF mcu from one of the guys on discord here.
this wouldn't be ready for a good few months though
I can think of a spot in the Los Gatos mountains this would be good at. Just need to make some friends up there
All this need to make friends; just downloaded the HAM prep app on my phone again. The motivation I needed to upgrade and renew my license. I think I only have a few months left đ
Got 3 nodes while inside a ham radio meeting
Inside
Thatâs crazy
This is 0.4 miles away
At first I thought someone else at the meeting had a node on but no
But it was funny I was talking about meshtatsic and tons of other people came up and asked questions
Also found a guy talking to another guy about Meshtastic
I was just looking at them and see one pull a t echo out and I immediately joined the conversation
just inserted yourself in there eh?
Yes
Common ham radio practice
When I was talking about Meshtastic one guy creeped up on me and started asking questions
"breaker breaker"
Yep
Got to meet @simple hedge and @barren socket in the flesh
Was great meeting you too @toxic kindle ! Wish you could have stayed and joined us at the pizzeria (spontaneous decision I know). @simple hedge and I decided to check it out and had a great time talking tech, including meshtastic of course. You could have met some cool who's who of the ham world including someone who has a repeater!
If I had my drivers license maybe I could have
Iâm not the one who chooses to go or stay
wot. how young are you
Might stay for the pizza next time
Sounds like fun
I like to talk more than listen

New email
Hey Benjamin,
âThe NRF52 board can do BLE updates. One of the people I spoke to said he uses a Pi that is plugged into the node to SSH into the Pi and update the node but I decided that is too complex for this use case.â
Yeah.. that would do it too though a rather complex way to do it. I'm sure there are remote USB extenders out there that use PoE as their base technology. I just haven't found them yet. That probably means that they will be expensive too.
âThis video is a good example of what the final build will look like.
https://www.youtube.com/watch?v=yTbt20A5JdY
To get the POE into the Wizblock an ethernet module will be used.
https://store.rokland.com/products/rak-wireless-wisblock-ethernet-module-rak13800-pid-100076â
I see in that "Rokland" URL, it says:
"Optional (coming in 2022 Autumn Launc Event) it supports PoE (Power over Ethernet) to supply the WisBlock modules."
Best I can see.. that PoE enabled system isn't available.
âI think having a Power injector with a battery that it switches to if power is not supplied will help with redundancy and make it.â
Today, we could use use an AC to PoE power injector but we're actively working on setting up battery backup at our Black site and at that point, we have various options. from basic DC-based PoE injectors like:
https://www.amazon.com/EverStar-iPoE-24W24G2DW-Injector-EdgeRouterX-UnifiAP-AC-Lite
We also have other PoE enabled Miktotik switches on site but I'm pretty sure all ports are occupied

It was again a great PAARA meeting, itâs something I look forward to every month!
Talked to rob and we are on for a 15 min Meshtastic presentation in a couple months
Let us know if you need a hand with anything.
Can you guys confirm something? I recently did a point-to-point test by leaving a node on top of my house roof and driving around town with another, as a basic range test. I sent test messages from various intersections as I was driving further away, waiting for the check mark ack from each one, as a sign of whether my message made it to my house or not. If it failed, I'd try 2 or 3 times w/ node on the car's roof before moving to the next spot. On my Android phone, no other known nodes in those areas. I did not do any tracerouting at the time b/c I thought the check marks were reliable acknowledgements. At 1.5 miles away from my house, I was getting check marks, and nothing further than that, so I thought that was the max range test for our area. Not so sure any longer. Upon checking the message history of the RX node that was at the house, many (~3/4) of the messages that showed me a check mark (from the TX node) aren't on the message list of the one at home (RX node). The ~1/4 that were found on the RX message list were from a couple that was only a block or two from my house! I thought I was getting 1.5 miles but maybe not??? I also got 20+ repeated messages received over the course of a day later from one particular intersection--weird. Anyway...
It seems like I was getting "false acknowledgements" that my transmitted messages were getting received at the intended node. So what do you guys think could have caused that? Hidden nodes? I understand the iOS app displays an "implicit ack from another node" message, which makes more sense than what appears to be inaccurate acknowledgements on my Android phone?
You should try asking in #help as it is more general. There are less people in the local Bay Area chat.
a checkmark on public channel only means your message was repeated by another node
the correct way to test would be direct messages to your base node.
a checkmark'd cloud is an implicit ack
Yes, everything was a DM to the house's node. On Andoid, I only saw two states: empty cloud icon or a silhouette of a person with a check box. I thought the latter was an ack of the intended node getting it. But maybe not? There isn't a 3rd state of that icon, right?
person with check box is a ack from the recipient
cloud with check box is implicit ack (some node repeated)
True, there are more than 2 states displayed. I've got many msgs with person with check box, but they're NOT found on the received node's message list. Missing at least a handful of them, maybe even 10ish
did you have a device connected to your base node?
if the recipient acknowledged them, shouldn't they be displayed? Yes, at the time of the tests, the Android phone was connected to the base node
fascinating.
are you sure those were person-with-checkbox and not cloud-with-checkbox?
Yup. I also got clouds with a slash through them, which I know is a failed send
hmmm
the device was in the exact same spot near the house's node, while I was driving around with the other node/device
maybe device went to sleep or and/or got disconnected?
I wondered that too but that's doubtful, b/c as I was returning back closer to the house, those msgs ARE present in the message list
as were the couple as I started driving away from the house (initially close to the house)
you need someone to man the base node... or a streaming camera.
or stream phone/device screen somehow
or my dog responding to my msgs in realtime (if I had a dog with opposing thumbs!)
đ
@simple hedge when you re-run this test, note the part above about making sure the device is close and connected to the base node before you leave. Double check that you can in fact see the incoming msgs, which is what I did too.
Will do!
I was at a place in emeryville and saw a few more nodes! I was pretty happy to see it
which ones? đ
Let me connect to my node and look.
af28 (kroo-tbeam)? d3bd (KN6PLV)?
Can anyone help me respond to this?
Maybe a node in the relay has store and forward turned on?
@remote vale Maybe, but it'd be a hidden node then, because I didn't spot any.
Can't do much about that. I know routing can take some interesting paths
Let me digest it
Confirm 50ft of cable from device to inside of shack is firm?
Yep
ok
Sorry, What I wrote wasn't clear....I don't think there were any hidden nodes. Apparently, there was an issue in the past with explicit ack w/out the recipient getting the msg. We'll re-test after updating firmware.
Yeah kind of, other than so many of them. đ€š
You guys think I can get Meshtastic written on a cap like this? đ
mystery penpal?
Send the obligatory âJoin the Meshtastic discordâ
Is that a heltec?
I have 5 or 6, I think
Wow
Wish they had gps
get heltec wireless tracker for that
Whatâs the battery life for them?
ÂŻ_(ă)_/ÂŻ never used one
but I guess it depends on how spicy it gets

airbag life 
Typo
So, looks like an off-the-shelf USB extender will do the trick. Wisblock uses a USB 2.0 spec. USB over ethernet extenders are out there, allowing well over 100ft runs. I might even be able to wire the reset button into it. I think this is the best way. At the user end on the ground, there will be a reset button, a USB to plug into, powered by a small AC adapter.
how about reset when power is applied (via tiny capacitor), and have a capacitor plugged into battery port too
Need the double tap capability
just toggle power twice and presto, USB storage mode!

I have a stupid idea. rak gets rectifier. when power is reversed, reset gets triggered
USB extender probably wouldn't like it though
RAK is best for power saving. it is less power hungry. Heltec is good for lower cost but be prepared to buy a larger battery pack for it
Ha! this was me driving around Folsom. I clearly made a typo. Don't text and drive.
What's your node id? Up here in EDH we keep getting someone sending messages but they can't hear us.
Shoot I don't think my router has a good view to Antelope. Not in my node list đŠ
Yeah its starting to grow. I have some nodes in my list from Jackson which is like 47km.
Folsom has changed a lot in the last 15 years or so. I moved up here from San Jose in 2007.
Mostly just more people and houses.
y u no miles
I read what is on my android app, never tried to change it.
No mater what its set for I'll be converting it for someone lol. My wife does km.
British spy
Maybe Norwegian spy, wife is from Norway.
