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
