I never used APF in the CQ 160 (who has time to tune in 5 Hz steps using
SHIFT or 1 Hz steps using VFO?) but here's a good tip for casual operating
from Wayne N6KR:

Use Preset I and II to toggle APF On and Off more quickly.  You can also set
different XFILs using the Presets.

I had a few problems like that but not sure it was N1MM.  I normally operate
SPLIT on my run frequency so I can use the BIG VFO A knob to tune RX
(leaving my TX fixed on VFO B).  Occasionally I noticed VFO B was not on my
run frequency!  Could be I touched the VFO B knob (which is a good reminder
to always LOCK VFO B when operating like this).  

If I was suddenly calling CQ on top of someone else, my apologies!
