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

First off, sorry to tell you, but you can not set your swr with your radio's swr cal knob. Trust me, I own a cb shop and know what I am talking about. I have been working on cb radios for years.

You must have an inline swr meter, which can be purchased online or from a truck stop. The ones at truck stops are cheap ones, but will do the trick for the most part.

You connect your antenna 18ft coax to the antenna plug of the swr meter, and a jumper coax (any length) to the transmitter plug of the swr meter and then to the radio.

Close all doors and make sure no one is messing around with the vehicle or antenna. You must be set up as you would normally be transmitting.

Now set your cb radio to channel 40 and your swr meter to fwd. Key up your microphone and at the same time turn the set knob on the swr meter until the needle is at the line that reads set. Unkey your mic and set the the swr meter to ref. Key up again and note what your reading is. Now leave the swr meter in ref and turn the cb to channel 1. Key up and take your reading. If the reading on ch 1 is higher than ch 40 you must raise the stinger on your antenna. If ch 1 is lower than 40, you lower your stinger. You are trying to get lower than a reading of 3 and as close to 1.5 as possible. If you lower your stinger as far into the antenna as it will go and you need it shorter, you cut the bottom of your stinger no more than 1/2" at a time, and recheck your swr reading after each cut.

Once you have gotten the best reading you can, connect your antenna directly back to the radio.

The setting your swrs is to make your antenna as efficient as possible, by trying to get it as close as you can to a 50ohm impedance. THE ONLY PART OF YOUR SYSTEM THAT CAN CHANGE YOUR SWR IS YOUR ANTENNA, not your coax and not your radio.

On the swr meter, the fwd/ref switch stands for forward (power that is being transmitted out) and reflected (power that is reflected back into the radio.

Just for information sake, the swr cal switch on your radio is used to set the meter to reflect the swr that your antenna is set at. The meter on your radio is like a dummy light on your car. ONCE AGAIN, YOU CAN NOT SET YOUR SWR ON YOUR RADIO, only the antenna!!

THE TALK BACK VOLUME IS CONTROLLED BY THE MIC GAIN, TRY ADJUSTING YOUR TALK BACK VOLUME ABOUT TURNING THE MIC GAIN FROM 12 OCLOCK TO 6 OCLOCK, DO NOT WORRY YOU WILL NOT LOSE ANY OUT BOUND POWER UNLESS YOU TURN THE MIC GAIN BELOW 11 OCLOCK

SOURCE: My friend would like to purchase a Connex CX 3400

These radios are know as what's called 'export' radios. They are imported under the auspices of being a 10 Meter Amateur radio and then through a typically easy modification are made to allow the selection of US CB channels. usually the modification involves plugging in a loose connector inside the radio radio chassis and/or removing a jumper wire soldered to a circuit board. If there is a nearby CB Shop they will usually do this for a modest fee.

Keep in mind that a radio needs to be Type Accepted by the FCC to be legal to use on the CB band in the US and export radios typically are not. Be sure to check the rear label for an FCC ID number.

The Cobra 29 has always been a good talking radio and is preferred by truck driver mainly for that reason! The Connex is a great radio in it's own right but sometimes needs a little help. I would suggest a power mic and there are many to choose from but Astatic is a clear winner! My two cents for a suggestion!

I have a cx-366ce cb cannot hear talking what is wrong


Is squelch turned too high that it is blocking too many signals?
Otherwise, it could be a faulty cable on the mic as the PTT button disconnects the speaker on the CB and a broken wire can cause the speaker to be disconnected.

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.

Has low volume with volume all the way up


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.

I BOUGHT THE CX 3600HP 2 YEARS AGO. IT WOULD STOP WORKING FROM TIME TO TIME AND NOW IT WON'T WORK AT ALL. WHO DO I CONTACT ABOUT SENDING IT BACK FOR REPAIRS


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.
