Well, I turned on my radio and surprisingly it plays well. With the dial set at 1200KC I'm picking up a station that broadcasts at 940KC. Please correct me if I'm wrong but I believe I've got too many turns on the coil (I added an extra 12 turns when I wound it). Tomorrow I'll start removing the extra windings to see if I can get the dial in the right ballpark. Is there a way to calculate how many turns to remove or should I do this empirically?
Thanks,
Keith
