This is a 10 meter Amateur Radio. You need a license to operate it. From my research it doesn't do CB Radio Frequencies. Here says Frequency Range 10 Meter 28~29 MHz https://www.walcottradio.com/connex-cx-4600-turbo-150-watt-10-meter-amateur-radio-p-2505.html and here shows your unit doesn't go low enough 26.960-27.410 MHz This Radio Standards Specification (RSS) sets out general requirements for, and provides information on, the certification of radio apparatus that is used for the general radio service, also known as the citizens band (CB), operating in the 26.960-27.410 MHz frequency band. https://www.google.com/search?q=connex+4600+turbo+cb+channel+guide https://www.google.com/search?q=Connex+4600+turbo

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
