On a less sarcastic note, do you have the ability to print out a picture? If so, there's a perfectly clear one in post#31512 from my compatriot Ted. It's from Giancarlo, who used his 'nut' to design it. The only difference I made was to take the connection from pin 7 and put it to pin 3. This is the 'audio in' to U1 in Farhan's original circuit. Make connections there as close and direct as possible - some have experience instability otherwise. Fred's solution in post#31517 is far more elegant and a whole bunch easier - *if* you find or can procure an opto-coupler. I'm lucky - The PC PSU I scrapped that provided the bits for my implementation of Ted's circuit also provided one! :) I'm not at home 'til Monday, so will be trying that, though I'd venture pin 3 rather than pin 1 - pin 2 is adjacent and to earth. Looks like you can put as many optos as you like in series there to drive anything else you want to ... like maybe antenna switching if you've done multi-band mods? Good t'inkin' Fred! (Oirish accent) :)
