Thanks, Ron. I did indeed have the BFO for FIL1 on CW-R on the wrong side.
I cranked the BFO parameter up toward the center value and beyond, and saw
another bandpass display (the right one) on Spectrogram. I had not
appreciated that you will get a similar display on either side of the ban

So I selected 600 as the sidetone and tried to re-do CAL FIL. CW
NORMAL went well, and I got slightly different values than for 650 Hz, as
expected. Most of CW REVERSE seemed OK also - except for FIL1 and FIL4.
For FIL1,
the BFO parameter was EXACTLY the same as for CW NOR
I completed assembly of #4565 and all seemed well. I used Spectrogram to
perform CAL FIL using the N0SS article as a guide, but chose 650Hz as my
sidetone freq since I thought I preferred a slightly higher tone, and selected
100Hz
as FIL4 bandwidth. I completed the CAL FIL process, with all
3 matches
