This is a Dak Mark X SSB CB radio that I acquired along with a few other base station CB radios from the 1970#39;s era. I could not pass up the ...

Check to see if you have a cb repair shop in your area, or visit a nearby truck stop and see if you can have them order them for you.

Hello, I am wanting to install a talkback mod on my Uniden PC78 CB. I am wondering if anyone could show me a schematic or diagram with a parts list on how to do it myself. Thank you.

Unless you want to be able to turn the talkback on and off, all you'll need is a 1 watt 47 ohm resistor and a soldering iron.

One end of the resistor connects to ground. The easiest place to connect the other end is at the external speaker jack. Find where the jack solders to the circuit board. There will be three pins, two inline and another offset to one side. You will connect the resistor to the pin closest to the back of the radio.

If the talkback is not loud enough, you can use a resistor with a lower value. If it's too loud, increase the value. 47 ohms is usually about right. Any louder and feedback squeal becomes a problem.
