I have it. It works great. You don't tune the CB. You "tune" the antenna
well, I tried to tune the coagulation between the radio and the antennae tonight with a SWR meter I got from radio shack, no luck. I turn on the radio and there is absolutely no static which I thought was weird. I tried re-pluging in the mic, taking off the antennae completely anything and everything and there is no static at all, but it still turns on and does all the functions just fine.
