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.

Hi list,
got a K2 from another OM on my workbench. It's got a
receiver problem and I just want to make sure I do the
checks in the correct order and I'm looking for hints,
if available!
Thanks in advance!
So here's the problem and what I want to do. It seems
the receiver runs with "handbrake on". So the s-meter
shows 3 bars without an antenna but the rf gain is
fully clockwise. I can reduce signals to zero (using
RF gain) with this K2 which I can't using my own K2.
So mine has a higher sensitivity.
Any idea what's wrong?
What I want to do:
- s-meter alignment
- I.F. amplifier alignment
- (maybe band pass alignment)
- signal tracing receiver and synthesizer
Kind regards
Gerhard
