[Elecraft] RF gain sweet spot

[Don Wilhelm]

Ed,

Something is strange.  It may be your ambient noise level, so try it 
with the K3 connected to a dummy load (or just no antenna).
Normally, as the RF gain is reduced, the S-meter indication will 
increase.  Apparently your K3 is doing something different.
At a 9 o'clock position, my K3 indicates S-7 when the K3 is connected to 
a dummy load.

73,
