Elecrafters,

I am keeping up with interest the thread on the use of RF gain, ATT, PRE, 
etc.  For the past several years my time has been spent primarily chasing dx 
on my favorite band, 80m. So far this season, I have managed to work 177 
countries on 80m.  This means like the 160 guys, I spend most of my time 
trying to hear weak signals amongst the band noise/qrn/qrm.  I have found 
what for me is a sweet spot with my K3 using diversity rx, with the nb and 
nr(1-3) , RF and AF gain reduced on both rxs.  I would certainly not turn 
down any improvement, but find the K3 quite good at digging out the weak 
ones.  I use Bose noise canceling headphones.  For diversity I use the 4 
square on the main and a short Beverage on the Sub RX.  I very seldom use 
narrower bandwidth than 2.0 Khz on rx.

I am looking forward to further improvements in the K3 and congratulate and 
appreciate the Elecraft team for their continued efforts on our behalf.

73,  Mike K5NU
