In general, the problem is that our walkie-talkies in multiplayer, on version 42.14.1, do not work as originally planned. Maybe it's a bug, or maybe we did something wrong, so I'm extremely sorry if I wrote to the wrong channel.
The situation is that both of us have a tactical radio that, in theory (as it is written), covers a distance of 8k titles, but for some reason, when we use it, it works at a maximum range of 100 titles, or a little more.
There are mods on our server, but there are no of those categories that would somehow affect walkie-talkies, only about 10 approximately.
And yes, we were on the same frequency. We tried to use stationary ones, which cover 7500, but for some reason they also do not really want to work.
