I Want To Add Talk Back Mod To CB Radio


there is what is known as the Quick and Dirty way, to add talkback to almost any CB radio. You will need a 130 Ohm 1/4 watt resistor. Open the radio and find the two mounting points for the external speaker jack and PA audio jack, you will want to solder the resistor across from the Positive connection of the PA jack to the Ground connection for the External speaker jack. This will give you talkback, and eliminate any feedback when the microphone is held at a normal operating distance away, Just remember, (This could potentially damage your radio if done improperly, I will not be held liable for anything that you do to your radio.) However, when done correctly this is a perfectly safe modification, and will allow you to monitor your output audio, as it is being transmitted. You can adjust the size of the resistor to your liking, however, I do not recommend anything lower than 100 Ohm, as there will be more potetial for squealing/feedback.

My radio squeals with echo when my amps on


adjust your talkback to just open then set your echo to where you want it. Now turn your amp on and re-adjust both the talkback and the echo . If you have a speaker nearby the radio may be feeding back through it so move it away from your radio . Now start talking with the mic and adjust your echo because you should be able to hear yourself talk through your talkback.

I want talkback on cobra 18 WX ST


Probably to Chassis Ground. You may want to experiment with the resistor value if you use a power mic. A 100 Ohm resister may be too low a value and cause audio feedback if you do use a power mic.

When ever i dead key the mic on med rf power i get a humming or bumble bee sound through my talkback same thing on high rf power i changed the coax it helped it for low rf power and tried new mic but had...


Thats because your Rf is powerful on high settings..try taping a AM radio "ferrite bar" to your coax in the back of radio for "RF filtering". Keep your power supply 15 inches away from radio. I recommend unhooking talkback on radios (it always causes feedback). But make sure speaker is good distance from the radio. I'd say 10 feet or so, behind radio. Change external speakers or add one with a long cord.

I have a TRC 502A CB radio that hasn't been used in about 5 yrs. I recently tried to use it and when I transmitted, the audio came thru the speaker. Any idea what's wrong?


it could be grounded inside...Somebody may had it set for Talkback features.. Take it apart look for speaker wires (see if soldered to resistors) if its shorted seperate wires ..just have speakers wires attached. Try external SPKR. Try different mics or radio may have gone bad completely.

When the mike is keyed to TR my audio comes thru the speaker. Cobra 29 LTD Classic. Best Regards Jim


If your voice is coming through the speaker when you transmit, it means you have talkback installed. If you don't like it, take it to a reputable CB shop and ask them to remove it.

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

I want talkback on my cobra 29ltd classic radio how do i do this myself


Open the case on your radio. Solder a 100 ohm resistor between the pa jack and ext speaker jack. You can add a switch if you like to turn it on and off. The lower the resistance, the louder the talkback.

I have a Cobra 29 wx classic and i get talkback through the speaker, and it doesn't have talkback installed!! How do i change this and what is wrong!! The radio works awesome rx/tx, but it just has this...


Have you tried using a different mic that you know is working properly? If it still has feedback, then someone has installed talkback. Take the top off, check for a resistor between external speaker and pa speaker ports. Remove resistor if it is there and that should remove the talkback. Hope this was helpful.
