Connex Radio Communications - Recent Questions, Troubleshooting & Support

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

it has a diode in back of radio near power wires. If it got hooked up backwards one time it will blow this diode and fuses from then on. Replace that Black striped diode near transformer inside radio. its in the far right. You have to take radio apart and solder in a new one or get a pro to do it.

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

Combination of hi / low switch and the band knob, I believe C band with the switch on low will give regular channels.

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 ..

buy a external swr meter.. usually like 10 bucks at any truck stop.
o your gonna need a jumper wire too for this.which is a short piece of coax you can get at any cb shop

I have CX-4600-T too. Mine gets way hot as well, I had a mod kit installed n it swings 215W peak power now. But the excessive heat is annoying, I think mine does have a fan in it though cause I know I felt air coming out the back before.

Turn the mode switch to the setting you want and leave it there .

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 .

try screwing it back in

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 .

www.cbtricks.com use the vr adjustment points to adjust the AMC modulation. DO NOT cut the mic audio limiter tr-32 or the modulation limiter tr-54. it will over-modulate and splatter out of band if you do
