Connex Cx-3600Hp 3600Hp 10 Meter 100 Watt Cb Radio - Answered Questions & Fixed issues

Question edited for FULL 'Make model (what it is)'. Question moved from Hewlett Packard (HP). Clean all of the volume and rotary pots with electrical switch cleaner. That is NOT WD40. Also when inside check the soldered joints on them. https://www.google.com/search?q=Connex+CX3400%2C+volume+issues ..

Use a longer antenna or get it higher.. 102" whip for mobiles. maco v 5/8, army big stik, or Bandit for base. or a long beam 5 or 6 element type. for example..

your power switch it faulty as there is a drop in voltage does the meters dim down?? then the voltage supply past the power switch it dropping as it draws more current or... the audio ic has damage or one of its associated capactors sometimes a diode can become leeky its used for AM modulation also

This means that your swr is high. you can damage the radio using it in this condition, check antenna and coax for damage or misinstallation

You've been close to another big radio......you think that was a question but I believe it is the answer. The rf amp transitor or the diodes in that circuit have been damaged. So that stage of amplification is not stepping it up for the next. Resulting in the electrical power converted to air audio by speaker isnt available. Cb shops refer to this as a blow front end. Tr17 is the transistor location .......just a side note some radios have a mic circuit check that dulls audio levels this is not the case here.

Great Question. I'm not sure if Galaxy would work on a Connex . Copper Electronics has a repair department and would probably fix it for you. I'd offer but I don't have a lot of spare time right now. It's probably the power connection inside of the radio or one of the legs on the main volatage regulator broke loose from the pc bpaurd. That's a common problem with those radios.

Service manual for the 4400 any use? It might be close enough? https://www.cbtricks.com/radios/connex/cx_4400_cx4400hp/index.htm ..

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

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.

contact connex and they will give you a repair number and let you know where to send it.

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

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.
