Just get a new one and have a good tech tune and align it. Might be a bit more expensive but look around at the truck stops if you have any nearby, they sometimes have them on sale for good prices. And with a new one you know no one has had thier hands in it messing about which seems to happen quite often!! JMHO. Goof techs are
DTB radio
Dougs custom CB shop
I know there are others but my brain just took a fart. Be careful who you do send it to as some places just snip, clip, and spread some coils!!
Good luck with your search at any rate and also check the what's for sale section here as well. Might be one for sale and you just not getting a response. Anyway, again, good luck and have a great day.
