I have been operating my K2 for just under a year now. In that time
I ALWAYS have left the PRESELECTOR on and the RF Gain up all the
way. I should have known better, but in case there is someone else
in the group who has done likewise, here's a tip:
Under high QRM or adjacent channel interference, don't be afraid to
turn off PRESELECTOR or even use the ATTENUATOR. Both are extremely
effective in bringing a sig up out of the noise...as is decreasing RF
gain.
I know most everyone knows this but it took me a year to try it so I
thought I'd pass it along.
It's just one more way to appreciate how the K2 "sings"...a truly
great RCVR design.
