I got a new CB from maplin on Saturday. I had some trouble with the SWR reading, it was in the red on some channels. I decided to cut the coax lead and desolder it, one end was fine, the other had completely corroded inside, there was no sheath or dielectric or anything, just a crumbled mess. New cable made and I'm getting from less than 1.5 on channel 1, to just over 1.5 on channel 40. I also achieved a transmit distance of just under 19miles!
