I have a connex cx-3600hp cb and it sounds like it has no power


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

Connex 3300hp big betty transmits fine on low power setting but when switched to high power hardly any modulation


well fellow truck driver here goes. When you take any radio back to a repair shop they are required by law to set it back to its original settings. I could fix it for you if you ever got to Massachusetts but you need it now so I would tell you this.Take it to a very good cb shop , tell them what went on and that you would like that big radio sound back. thats it.

Got a connex 3300HP has a ranger board and chipset won't modulate recieves fine keys up relay clicks needle doesn't move no voice either cant find schematics


You may have a dead meter.
Modulation is audio's affect on swing wattage or pep. Notice that needle moving more with your voice.
Dead key or carrier wattage is without your voice enhancing the power only with mic keyed.
I can only assume that the chipset you are referring to is an ic chip audio or pll which must be working if you are receiving audio.
Check your mic cord................ transmit and modulation and even your receive volume can be affected by the cord/mic plug solder joints or broken wires here.

I have a connex 4600 turbo very good radio!! But the other day I keyed up my mic and the radio shut off but came right back on when let go. Do u know what that might be?


check for any loose power connections.. ground connections.. loose coax.. also make sure vehicle is on so not to drain battery down when TXing. if it was off it may have dropped battery voltage down lower than it should... and turned off.. RX doesn't use hardly any ampres..

Connex 4600 turbo. Poor receive. About 4 mi.


Hi there!!

The Connex 4600 Turbo is a very sensitive radio these radios don't work good at all with the stock microphone! The best microphones are the RK-56 and or the Astatic 636L which most people use and you shouldn't get any squeal. And make sure if that you are using an external speaker get it as far away from the radio as you can facing away from the radio so it wont feedback. As far as a Mod kit there are several ways to modify the radio which most are pretty hard and drawn out. but the most easy that used to be used is as simple as a diode placement in the right place which is old school but still works good. You must be very careful as if you are to slightly touch the wrong points the radio could be destroyed and no longer work so caution is to be taken if you don't know what you are doing please don't try it on an expensive radio!! If you want more info on the mod e-mail me

never the less a Modulation kit or modification wont help your Receive it will only help your Transmit signal!!

Modulation with my linear


the radio you are trying to fry your amp with is driving the amp to hard. that radio has a toshiba 80 watt final inside the radio you are killing your radio with the dead key at 2 watts it causes the final to overheat and shut down because it is not built to be turned down that much. its best to turn the radio back up and use the radio.

Engien revs and lights dim when i key up


You don't say how much power you  are running, but it must be quite a bit, or you have an amp you're not telling us about.  By keying up the radio, you're putting enough load on your electrical system to pull the voltage down which causes you lights to dim, rpms to drop, etc.  When you key off, everything goes back to "normal" which means no load so the engine will surge momentarily before it recovers.  Depending on how many watts you are running, you may also be affecting the alternator regulator.  Your alternator may also be a little weak.
