[Elecraft] K2 receiver problem

[Dale Boresz]

Hello Gerhard,

First, do the AGC threshold adjustment (instructions located at end of 
Assembly, Part I in the manual)

Then do the S-Meter Alignment, the instructions of which follow the AGC 
threshold adjustment instructions.

It sounds like the AGC is set a bit too aggressively at the moment.
