FM 88-108 transmitter

[crisp thistle]

Hello. I have for sale simple FM 88-108MHz transmitter. It can be powered from 18650 cells. It is recommended to use a voltage regulator on VCC input. I can provide both voltage regulators and simple antenna (copper wire) for small price. Transmitter alone cost $25 (22.5€, 90PLN). DM me for shipping options. Below is a photo of PCB.

Its portable? And how about power and rds?

[crisp thistle]

Hello. Yeah, it is portable if you make simple case even from cardboard (its small). RDS is supported

It can be powered from cells like 18650. I can provide voltage regulators so battery discharge wont affect frequency

[shell glade]

How about frequency changing? Also can i customize rds text? Btw its inlegal in lithuania i think, what should i do when i buy this if i decide?

[crisp thistle]

You change the frequency with potentiometer. RDS can be set from PC software. This software also give you option to set PI code. (i can provide it for free). If you won't affect already occupied frquency, chances of problems with law are small.

I can also support with setting up software

I have car fm transmitter and im always using 88.4 mhz

No one is using it

[crisp thistle]

So yes, it can be set to 88.4MHz

[shell glade]

Ill maybe buy it then

Lemme check my bank account

[crisp thistle]

Okay, please DM me for purchase options

[crisp thistle]

Okay, no problem

[shell glade]

Im ready to buy

[crisp thistle]

Okay, sure. Ill DM you

[crisp thistle]

2 transmitters left

[ruby swallow]

You posted an image of a PCB is this a complete assembly or?

[crisp thistle]

After purchase, I solder every component on PCB.

[ruby swallow]

Ah

I figure probably shipping to us is no go?

[crisp thistle]

hmm

ill be honest, i never shipped abroad

[ruby swallow]

Ah

Shipping cost might be prohibitively expensive

[crisp thistle]

If you know how to do it, then sure

[crisp thistle]

yeah

[ruby swallow]

Tho, curious if he could solder like an SMA port on it or something for antenna output?

Looks maybe difficult given pcb design

[crisp thistle]

I only used it with copper wire antenna, so I don't really know

[ruby swallow]

Ah

Don’t hold one for me go ahead and sell it just me being curious

[crisp thistle]

Sure, i still have 2 left, so no problem

[summer glacier]

Hello, I think I might want to buy it too, but I have some more questions, DM me 🙂

[crisp thistle]

sure

[crisp thistle]

1 transmitter left

[round jolt]

how much RF comes out the back

about 25dbm i presume?

[crisp thistle]

hmm i dont know in dbm, but its like 40-60dbf

[undone fulcrum]

You should have spectrum analyzer and power meter for this things

[crisp thistle]

yeah i don't have that.

[crisp thistle]

Okay now i know transmitter makes 92dbf

[undone fulcrum]

This isn't RF output power...

[crisp thistle]

tuff

[shell glade]

I got it and i can say its actualy good! One more pirate to lt xd

Im getting 92 dbf on my tef.

You can check in kazlu ruda web server

[sullen lintel]

Does it use an integrated IC like the Chinese TXes or a PLL/VCO design? 🙂

And can it work with MPX input?

[crisp thistle]

Nope, its on transistors.

[crisp thistle]

It support rds

[sullen lintel]

Does it have a built-in stereo coder? And how does the RDS work, which software does it use? 🙂

[crisp thistle]

Mono only. I make rds using stereotool

[sullen lintel]

Oh that's great, so it accepts MPX!

Do you ship to Bulgaria?

Does it have a lot of spurs?
