How To Listen To Your CB Audio ?

If you are using it on AM, then that is a relatively easy thing to do. You need to make an RF sampler (L1; just wrap a few winds of wire around your antenna coax), and then add a germanium diode so that the signal can be demodulated. Don't need the variable cap (C1) as shown in the schematic; instead use a resistor there. Then using a xformer instead of headphones, you can bring it to an audio input to an amp/equalizer. SSB is harder to do.

Yup; probably the better way to go. You can buy a simple SDR receiver for about $18 that hooks up to you PC or laptop and comes with an antenna. Does SSB and FM too.

I recently saw what you are asking about on e-bay.
It was basically an in-line unit like Robb outlined.
You used a coax jumper into the assembled unit
between the antenna and the transmitter.
Your headphones are plugged in for you to monitor.
It was $39.00.
I looked again ad did not see it.
I believe these are often listed.

I tried that.....didnt work....lots of feedback.I always used a second rig with the RF gain turned down, no antenna connected, through a set of headphones. Not economical unless you have a second rig already.

Could u use this device to listen to your radios audio output and use it to fine tune your audio going through your rack gear...or is there a lag time that would make it not good for that?
Also does it come with the software to make it work on yer pc?

The software comes with it. Think that HDSDR will also work too - IIRC. Hams will wire the IF output directly to these dongles and monitor receive in real time; so I doubt there is much lag time - if any. The filters are fully adjustable for width, so you should be easily able to adjust your audio.

That's no different than adding talkback to the radio with a resistor across the PA and ext speaker jack. You are hearing what comes out of the audio chip but not what you're transmit actually sounds like.
