Hi together, I play with the thought to get myself a PMR radio, so one of these little walkie-talkies with earphones, microphone and speech button for handlebars. So that I can communicate with the comrades while driving. The parts are everywhere relatively cheap. Question is now, the things have different channels. Can I talk now only with two devices from one set? Or can I talk like with the CB radio with a device of another manufacturer If I set up the same channel on each device, I’d like to connect to a conference circuit. Would be interesting if someone had information for me, thank you ! Greetings
