[Elecraft] Transceiver Test Bed at W3LPL

[Barry]

Frank,
     I can't speak to the other radios, but you do need to fiddle the 
values of the AGC on the K3s to get the best out of the radios. I think 
the defaults are just to see if the radio works or is where it was left 
while undergoing QC at Elecraft.

BTW: I'm glad one of us is doing something worthwhile. ;-)

73,
Barry
K3NDM
