JimB,
Thank you so much for the education regarding the trimmer capacitor. I might substitute the potentiometer, RV2, for a larger, better made unit, but that's merely to help tune it station to station. Unless you and board think that's a wasted effort as well.
Audioguru,
The documentation is inadequate, I agree. Just a sheet of paper would be great, talking about the theory, etc. But it is what it is. I actually sought out this unit, because it's no longer in production. The "new" Velleman radio kit has digital tuning, with only up/down scan. No dials. Just doesn't feel right, but what do I know.
