My K3 has 2.8 and 2.1 8 pole filters in both main and sub receivers.  Set up
for zero offset per manual.  When I switch to 2.1 filter, I need to use the
Shift control to make receive audio sound approx normal.  Perhaps 3/4 khz
shift.  Is this normal?  When using the 2.8 filters, no shift is needed.
