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.

If their isn't a switch you will have to go into it and disconnect it. I would recommend having a professional do this. It is very miticulous.

SOURCE: feed back thru external speaker, very bad

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.

SOURCE: how do i cut out talkback out of my connex 3300

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.

Connex 4600HP, recently added a bed cover to my truck and had to move my antenna, now that I moved it, I am getting a squeal on my cb when I key the mike, especially with the talkback on, which I have left...


The only thing that comes to mind is to make sure the antenna is well grounded and to make sure that where it's been re routed that there are no power wires next or close to the antenna wire which can cause interference which will be more noticeable once you turn on the truck.

I have a Connex 4600 Turbo mounted in the headliner of a W900L Kenworth using Wilson 2000 twin antennas and a RK56 mic. When trying to use the "talk-back" feature all I hear is constant...


Strange. You shouldn't have a squealing problem with an RK56 noise canceling mic.

Unfortunately there is no way to change the volume of the talkback. Its too loud. The only solution is to turn the mic gain down.

The only reason you need to have talkback on is to check your audio. Make sure the echo is good and what not. After that you really don't need it on. So turn down the mic gain, then check the echo, then turn off the Talkback and turn the gain back up.

The squeal is feedback from the talkback being to loud and being heard by the mic. So the only way to solve it is to lower the volume of the talkback, (Which is not possible in this radio) lowering the mic gain(which lowers your audio level) or turning it off.

Want to get talkback in a cobra 29


When you key up the mic ungrounds the speaker so you don't hear anything through it, so to get talkback you're putting a 100 ohm 1, or 2 watt resistor between the switched side of the speaker and ground, now when unkeyed the mic grounds the speaker as usual, but when you key the resistor allows a bit of audio from the audio amplifier, not decoded RF, to still get through. I think the pa/ext spkr. jacks are a convenient place to connect it. You may decide to control talkback by running the circut thru a switch like brite / dim switch . Want less talkback, use more resistance, 150 ohm . Too much talkback can become feedback . I hope this helps, J
