Connex 3300 cant get receive on internal or external speakers no receive

FOR ALL YOU MISS GUIDED FOLKS CONNEX IS NOT PART OF COBRA IN ANY WAY SHAPE OF FORM PERIOD ...CONNEX IS MADE BY RANGER U S A . AS FAR AS THE RECEIVE IT IS PROBABLY ARE MISSED SWITCH OR CONTROL NOT SET RIGHT SIR

RF gain or volume turned up all the way?

Keeping it simple first

1. Try another mic it could be a short at mic plug/cord
2. Plug in an external speaker or check internal speader wires for short


You refer to it as a Base so i would assume you are not mobile. Vibration in a vehicle can be devastating to solder trace side of radio pcboard.

Plug in an external speaker to the pa jack ... Switch the band selector to pa and see if you hear yourself... No? Bad audio chip

The RX wire could be broke in the mic cord. You will still get receive when you have the talk back is on, but it will be low. Try another mic.

Hi, my name is John. Try a external speaker, plug it in the back of radio, turn the RF GAIN to MAX. Turn the SQUELCH all the way to left, make sure the select knob is on CB, and on AM...try all this and if that's does not do it, let me know, I will post other steps here,.... hope this was very helpful....

Have your antenna checked at a place that knows what they're doing. If your antenna system is bad, ground problem,coax bad mount or maybe just a wrong or bad antenna. Then the sounds not getting out the antenna and its feeding back thur the radio.If your echo board was bad then your radio wouldn't transmitt at all.
If you unplug your external speaker will it squeal? If not do the antenna and if that reads fine just try a better speaker like a uniden 20watt speaker.I own a CB shop and this is easy to fix.

peak receive? Not sure what you mean. You don't peak receive.

If you want to align the receive, then you will need some specialized equipment. Oscilloscope etc.

get a K-30 antenna ist magnetic if that dont work your speaker in the Cb is broken

The Connex radio is a division of Cobra, and no offense, but Cobras are one of the cheapest radios around. The problem with your Connex is a simple receiver malfunction. The receiver probably worked great until it was put into storage for a long time, you can replace the receiver, or you can fiddle around with the receive gain until you hear something. But you may just want to send it to a radio store and have it looked at, to be honest with you, Connex is a terrible radio, they sound good, but they're terrible radios. Go with Galaxy or Uniden radios, you won't be disappointed.
