don't hit any more bumps. The problem could be in several areas. I'm going to say that you may have a loose capacitor inside If I had the radio here I could fix it but because the problem may be so spread it could be a lot of things Are you a truck driver? If you are take it to a CB shop at one of the many truck stops and see if they can fix it for you .

Hi there, if you are talking about the Connex CX 3400 HP there is no sideband or SSB on this radio. It is only AM and FM 10 meter Ham radio. Many people do modify these radios to include the 11 meter frequencies which is the CB band. Maybe knowing the actual bands and their frequencies will help some too this radio does have 6 different bands ranging from (Band A. 28.015 thru 28.455) (Band B. 28.145 thru 28.585) (Band C. 28.115 thru 28.555) (Band D. 28.085 thru 28.525) (Band E. 28.055 thru 28.495) (Band F. 28.025 thru 28.465.) I hope this will help you. Bob

if your swr is higher on 1 then on 40 then your antenna is electrically short and you have to lenghten the antenna.If it is higher on 40 then on 1 then it is long and you have to shorten it. If you have to make it longer then you may have to add a quick disconnect or a coiled spring to make it longer. To make it shorter all you have to do is trim a 1/4 in at a time off the antenna whip but you must keep checking the match until it gets down below 1.5 .

Have you tried keying it without the coax attached ? Take the mic apart and give it a squirt of electrical parts cleaner .Try using a different mic also.

If you disable any part of the radio that does not pertain to CB then you could actually do damage to the radio. the best thing to do is leave it on the CB band and don't touch it.

the radio is searching for a strong incoming signal and until it gets one it will search for one. Try turning off the scan button .

many trucks have a ground wire in the harness as the cabins are fibre glass or not grounded around the cabin mounts If the radio grounds out through the frame , then there would be no ground for the radio or the aerial wire
to fit this particular may require such a wire in the harness for the radio which it probably doesn't have
As you have been alerted to a problem, it would be advisable to talk with professional radio fitters who work on trucks to get the correct advice before starting on the job
it could save a lot of frustration
