[Elecraft] [K2 4922] IF Amplifier Alignment

Colleagues,

I've moved on from the BFO issue (now resolved) to an IF alignment issue.

My problem is a constant S3 reading on the S-meter.

RF gain control works and is all the way turned up.  Birdie at
6.999.17MHz is clearly readable but is only strong enough to push the
S-meter up from S3 to S5.  When I move off the birdie frequency I hear
nothing on the headphones.

Mode:    CW
Filter:  FL2
RF gain: full
AF gain: 12 o'clock
Preamp:  on

The S-meter increases as the RF gain is decreased (as expected).

As the constant reading masks the S-meter reading it is hard to peak
the IF inductor L34 for maximum signal.

Where to go from here?

Thanks,

Ron
