[CQ-Contest] Receiver adjustments in CW contest conditions

[Pete Smith N4ZR]

I'm curious to know - except maybe on 160 or VHF, most of my receiving 
problems in CW contests seem to come from QRM. When I'm contesting, I 
find that the only RX controls I use on my K-3 are the main tuning or 
(when running) RIT - this despite having DSP control to shift and narrow 
my passband.  I just go with my 500-Hz filter and my ears.

So what do you do?  What have you found useful - again, not in 
weak-signal situations, but in QRM.
