I'm looking forward foundering this done.
I currently have an aftermarket system with aux port but I also have a stock radio (which i prefer to put back in) sitting around.
Be interested to see if finalized and set up!

I think it will be pretty slick. The simulations make the delay before music comes back on to be pretty ideal. A small break in squelch dosnt seem to charge the capacitor much. That way the music comes back on much quicker then the normal adjustable delay. Also the qrz guys gave me the idea to replace the pots with resisters. After i figure out the right values then nixing most of the pots drops the size, cost and complexity down alot. The pots just made more sence when i was going to volume control everything so that the ham/cb were louder.
I have this about figured out now with the circuit. I think this will be the final parts list
