The only other mod I've done is a 4 pin hookup for a Uniden mic. ?I will hook up the watt meter and see if anything is transmitting.

Re: Adding speech compression.
Good question. ?I doubt it will affect receive unless you get a really strong station, and at that point it might be desirable as it could save your eardrums if wearing headphones. ?There is

Re: Tuning with Si5351 and Rotary encoders
Sorry, but I put your code somewhere I can't find it. It would be best if I worked from the code you have now anyway. Yep, and I'm looking forward to it. I've been there the last three years and have

Re: Tuning with Si5351 and Rotary encoders
Eric, The code I'm using is a little different, the interrupt calls set frequency ISR(PCINT2_vect) { ? unsigned char result = r.process(); ? if (result == DIR_CW) ? ? set_frequency(-1); ?

Fixed! The no audio driver issue is fixed. I replaced the electret mic element and wiring. Thanks to all that had suggestions/comments. I used an identical looking element that had solder pins, from

Hello Jack (et al) I downloaded and loaded that library and got no immediate change. Fiddling with it, the section that you recommended adding to the set_frequency function works but the set-case
