Try the voltage regulator or the power supply circuit

My connex 3300hp radio randomly transmits and gets stuck without pressing mic button. It in sticks if you press mic button.


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.

How do I wire a MIC on a Cobra 29 LTD classic 4 pin mic?


would need to know the mic wire code you going to use. but half moon cut out at top as you look at it is top left 1-4 next row left side 2-3. 1 is cable/ unshield (common). 2 is MOD 3 is TX 4is RX... 1 is wire with no cover 2 is with cover rapped round wire RX is received TX is transmit, hope this helps. newer mic have different code wires so check with meter, red green and blue and shield is on some of the new wiring.

Does the connex 3300hp have talk back


Any radio can have Talk Back.. all it is is leaving the RX active on TX and the sampled audio goes to the speaker that you can hear....

My tx rx light comes on when i key mic on my connex 4300hp ,,why


Check the mic wires inside the connecter, there might be a loose or broken wire that is making an intermittent connection.

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.

Have a new connex 3300hp i can hear everybody else but nobody can hear me when i key up and talk the needle dont even move


look up the tune specs VR13 (L PWR) L32 L33 high power maybe your watts are turned down if it is brand new send it back to the place you bought it from.If the watts are turned all the way down you won't get any carrier your needle is not moving when tranmitting there is no rf power check to see if your tx light is on when depressing the mic button. you should have a rf adjustment turn it clockwise to turn the power up on the front of your radio.or the mods i gave you in the radio.

Put another **** on 29 ltd and lost key up and receive but it still lights up. What you thank is wrong. 5 different mics, all work in my other radios. I heard something chatter and it would not tx or rx...


Check to make sure that there is noting shorting out inside of the radio. some mic plugs can turn from overtighting the mic connector.. also check the pins they may be broke or compressed too much and won't make connection to any mic.. Pin 1 is ground and pin 4 is rx.. take a jumper wire across those and see if you get rx back. same for tx pin 3.. jumper pin 1 and 3 should have a key up. pin 2 is your of course audio. these should be first things to check. cobras unidens and galaxys, connex, genlee etc. are wired the same. midlands and radioshacks ge are different. so make sure your mic is wired for a cobra or galaxy also.. any mic will work on any radio. as long as is it wired to it correctly....

Connex 3300 mic wiring


I opened up one of my Cobra HighGear mics and here is how it is wired:

1. shield (Bare copper wires) --- twist them good and tin with a little solder

2. audio (White)

3. transmit (tx) (Red)

4. receive (rx) (Black)

Blue and Yellow are unused.
