Jack,
Can you share the sketch/code that has the encoder automatic tuning increment as mentioned below?
We don't all have access to QRP Quarterly.
thanks

I do use a rotary encoder to tune my Forty-9er (see March, 2016, QST) and will likely soon add one to the BITX40 I just bought. The increment is an issue that is often one of personal preference. For CW, I use a 100Hz increment as the default. However, if I want to traverse from one end of the band to the other, it takes a bazillion turns of the encoder shaft to make the move. To overcome this limitation, I wrote a routine that senses how fast you are turning the encoder shaft using one of the Nano timers. If the "detent spacing" is fairly long, that is interpreted as you slowly fine tuning a station. If the spacing is short (and you can define the time differences), the software automatically increases the increment to 50KHz (which you can also set). As you zero in on your target frequency and slow down the shaft turning rate, the software automatically drops down to the default tuning increment (e.g., 100Hz, or whatever).?
