[Elecraft] [K2] Trouble dialing in KAF2's AF2

[Brian - N5BCN]

Hi all,

I aligned the KAF2 using a XG1 and Spectrogram.  I tried the broadband noise
method, but found the line for the peak very coarse, it seemed the XG1 peak
was much more stable and easier to discern.  Regardless, I thought I had R1
and R2 really dialed in for both AF1 and AF2.

AF1 seems to perform as it should: ever so slight drop in signal strength,
but nice audio filtering.  AF2, however, causes a significant drop in signal
strength.  The instructions suggest that AF2 should have no drop, and, if
anything, a slight increase in gain.

Any ideas where I'm going wrong?
