OK, while driving thru Richmond on 95 a couple weeks ago I tried to tell a trucker he had a flat tire on his trailer before it fragged me or someone else. Keyed the CB, said my piece, then had the pleasure of hearing probably 20 truckers raging for the next 5 minutes about the moron with the squealing radio. Thankfully they weren't able to hear me ID my vehicle, 'cause they probably would've run me off the road; they were pretty spooled up. Anyhoo, I'm now wondering what the deal is. Antenna is a Wilson 500 mag-mount, it was in the middle of the roof. Radio is a Midland 77-162. Both are box-stock. Receiving is fine; I can hear who's got a noise-canceling mike and good setup vs. a ghetto setup. Would having the antenna tuned help this? How about "tweak & peak" of the radio? Is this even possible on this radio???
