if you get info send it my way

well based on what your looking for all I can tell you is it consists of a key, microphone, frequency converter of some sort and frequency detector/microphone, an amp then output to speaker.

but the info i am looking for is if there are skematics for a 2way radio to use more than 1 channel at one time on the same radio because when u switch channels the other is completly off or is it? I think the receiver is controled by a saved program on these if so is it rom

so if you can help it would be appreciated
