Radioroslyn, I see the feedback circuit now. I did rewind it with 18 turns of 38 gauge wire but I have my doubts whether I did this one properly. During the build, I removed all of the crumbling cellulose and neutralized the windings underneath with ammonia/water. I replaced the cellulose with a piece of acetate and wound the coil around that. I think I need to pull the coil out and check the direction of the winding.
Is this coil suppose to be 18 turns or 17? One symptom I noticed is that 640 kc is near the middle of the dial and 1260 kc is near the end. I only got as far as tweaking the three IF trimmers before I ran into this problem.
