Vic and Stewart, Tanks for answering
well, the ripple on the CW filter at 2kHz BW is abt 8db p-p.
the gain difference when the CW filter is offset to 1.2kHz
(for digital modes) and its BW is 1kHz is abt -3dB relative to
the OP1 filter (not bad?).
with the same at 200Hz BW the gain is -10dB relative to the OP1.
Maybe this is normal,
