Well I was given to me a roger beep it has only 4 wires power,ground and that leaves 2. Now I have never done any radio work before in my life and have been watching you tube to learn how to solder. I have been reading the instructions and it seemed very possible I could do this. I just need to find out what color wire does what on my 148GTL Malaysia aprox 1990 mic receptacle and I do plan to also install on/off. Any tips other than throw the roger beep in the garbage. With the skip coming in everyday local talk is rough. My Cobra 148GTL is my base radio.
