I didn't change the delay but did modify the increments to make the tuning smoother. Especially for CW the 10Hz?
increments makes it easier to tune to the correct frequency and avoid the sudden jumps in the wilderness:
void doTuning(){
? int s;
? unsigned long prev_freq;
?
? s = enc_read();
? if (s){
? ? prev_freq = frequency;
? ??
? ? if (s > 10)
? ? ? frequency += 20000l; //!!200000
? ? if (s > 7)
? ? ? frequency += 1000l; //!!10000
? ? else if (s > 4)
? ? ? frequency += 500l; //!!1000
? ? else if (s > 2)
? ? ? frequency += 100l; //!!500
? ? else if (s > 0)
? ? ? frequency += ?10l; //!!50
? ? else if (s > -2)
? ? ? frequency -= 10l; //!!50
? ? else if (s > -4)
? ? ? frequency -= 100l;
? ? else if (s > -7)
? ? ? frequency -= 500l;
? ? else if (s > -9)
? ? ? frequency -= 1000l;
? ? else
? ? ? frequency -= 20000l;
? ? ??
? ? if (prev_freq < 10000000l && frequency > 10000000l)
? ? ? isUSB = true;
? ? ??
? ? if (prev_freq > 10000000l && frequency < 10000000l)
? ? ? isUSB = false;
?
? ? setFrequency(frequency);
? ? updateDisplay();
? }
