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.

Re: Raduino BFO hook up?
OK Group,
I have W3PM's code working with some slight modifications to the software and hardware (I had to rewire The clocks and add a push button for band change).

Re: Tuning with Si5351 and Rotary encoders

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);
?
