Any body know what CB Secrets Vol. # covers the internal adjusts on a Cobra 29 NWST? I want to turn up the modulation to just under 100% to get it ready to sell on Craigslist. It's a great radio for someone who just wants AM but I'm going to unload my AM radios. I downloaded all the CB Secret volumes but it takes a while to go thru them all. Thanks in advance!
