Looks like I'll have to break down and buy a signal generator. Know of any cheap ones that work well enough for this type of operation?
When the radio is tuned to the low end of the band around 530 or so and at the top end, it squeals. Is that the oscillator running? Is there a way to check it with a transistor radio?
I'm pretty sure I wound both the antenna and oscillator transformers correctly but I can go back and check. You say that the secondary windings on both the antenna and oscillator coils were about 25 turns. The oscillator only had 14 and the antenna had 19. Think I should increase the number of turns? Also, is wire gauge critical for both the primary and secondary?
