Question about Connex CX-4300HP CB Radio
Oin 2 may be grounding, or the relay contact is not opening to break the circuit of the recieve section. Or your SWR is so bad that what you are hearing is from energy transfer alone and copper corrosion can act as the detector diode.

Turn the talk-back OFF. You've got yourself a little feed-back loop happening whilst the talk-back is on.
Most squeling is caused by either AUDIO feedback or RF-induced feedback by running too much power, improperly grounded equipment and/or a high vSWR.

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.

There are many versions of the 3300 , however in most cases (not all) remove the yellow wire from the "echo" switch. Let me know if this helps.
