Good to know for DX mode, also good to learn something. Had I thought it through it makes sense on harmonics alone.
In regular mode, I stay between 1500 and 2200 Hz, so I don’t have to futz with the input level (either the sound card or the line in is not flat, then it power hunts). That means also that harmonics are well out of the filtered range. Thanks! I’ll try it.
