unless you have the equipment to do this.. please take to a radio store. have them do it.. its free. or they shouldn't charge to do that service.. unless it needs a major factory alignment.
also they shouldn't take out or clip anything in the process if they do find you another place LOL..

  • Yes you can. This is actually a service manual but it covers the basics found in the users manual in the first part of the first link. Also with a service manual you can dissect the radio to perform repairs.

  • Part 2 -

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

Sorry we do not sell parts nor have the ability to locate them for you.

If you ground the audio wire, you will have no noise or mic function at all. The mic hot wire and the shield should be enough to avoid hum.

Is the CB getting its power from the amp(?) By amp I will assume you are talking about a signal amplifier..

Connex Radio... | Answered on Oct 05, 2016 | 125 views

people think that if they peak and tune a radio it will work better. First, if its brand new from the factory you shouldn't have to,all you should have to do is lower the dead key raise the modulation and you are good to go . The proper way to do this is with a spectrom analyzer . Do you have one? Cheap on ebay ,may 4000-5000 dollars but if you get one and set that radio perfect you should hear anyone complain that you are interfering with their radio.
