I just bought the 757SX version and the sound comes in good but, no mic with it and I can't find one so, in reality, I can't test the send out and I'm still looking for a mic. A really nice looking CB, I like the channel wheel spin and it sounds good so, a little advice don't try selling it without a mic or, you might get it back...
