[Elecraft] Reply on Simple K2 RX Mod

[Kenneth A. Christiansen]

Wayne asked if this mod helps and here is my experience. I upgraded all of
my K2
except the software to the "B" version and added the two diodes as suggested
by
Wayne. I belong to the North Dakota Goose River 160 meter SSB net that meets
at
14:30 on Sunday mornings. I have three strong local stations and the rest of
the
stations are 50 to 200 miles away and weak. Every other rig I have owned in
the
last 20 years had problems with the strong local signals. The K2 would get
distorted
but with the pre amp off and attenuator on it didn't sound too bad. This
morning
I turned on the pre amp and set the volume for the net control that was 70
miles
away. When the strong local stations came on they were clear as a bell and
no
louder sounding than the net control. Of course they had a better signal to
noise
ratio. The recovery of the AGC was instant so I never missed a word of the
net
control. My Omni-D and IC737 never could handle the 160 meter net and before
I added these diodes to the K2 I had to turn off the pre amp, turn on the
attenuator and ride the AF gain between the net control and the local
stations.
I am impressed enough I now plan to order the KPA100, KAT100 and the
external cabinet so I can have the best of both worlds.
