Realistic TRC-430 by Radio Shack CB Radio – Overview and modulation adjustment location

There’s a surprising amount of information available about this little CB radio and I’d definitely recommend visiting CB Tricks – to check out everything they have on it.

Surprising for such a small 40 channel radio it does have a modulation adjustment inside to boost the audio performance. For cheap radios like these turning up the modulation will definitely help them perform a little better (especially with the stock microphone).
