Make sure you have the IF's aligned per the manual as the selectivity,
sensitivity, and the slot depend on this. This is the same as with the
HQ170, 145, and 180 that use all or part of the HC-10 circuits.

OK, thanks. The IFs seemed to be well aligned, so I didn't check their freq
against a generator. The slot filter works on the 455 KC IF (the 160 doesn't
have the 3rd, loew 60 KC IF that the 170 and 180 do).

In fact, my 180's slot filter operates at 455 KC, not 60, which seems odd but
it works great.

Anyway, it's conceivable that my 160's IF is off, but it would have to be 10KC
or more off to be unreachable with the slot filter adjustment. But, next time
I have that radio off the shelf, I'll check the IF center freq. FWIW, the dial
calibrations line up *very* well -- I did touch up the front end alignment, and
the dial accuracies are worthy of a Hammarlund. Tnx es 73, Mike K.
