[Elecraft] well-known RCVR tip (but wasn't well-known by me!)

[John Wiener]

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.
