Hi John.
The IF worked pretty well once, as you and Terry said, with the loop back in place. Still having difficulty with the low end ...580Kc tuning. I have tried moving both the signal generator freq and the tuning cap to find a mutual ground on the bottom end....I'm going to try again tomorrow. The 19 compensator does not seem to do a lot well actually 19A either really.

Any thoughts?

thanks again.
