I just got a walkie talkie for the first time a Motorola T210 and need help understanding I search the channels and hear people and they sound like they know each other but at the beginning they would say something like “207 WRG” or something or would ask for a radio check I try to talk to them but it sounds like the don’t hear me or sometimes I will search channels then hear randoms Morse codes that play every so often. Also hear robotic voices about the weather or something. And I would hear random people on my channel and I’ll try talking to them but they don’t hear can anyone tell me or help me understand?
