Well done that man! Building a set from scratch is a really worthwhile and satisfying experience. I'm a bit confused why you had to change the IFTs to 455 KHz though. Could you only get an oscillator coil to match that IF?

If the aerial coils and the oscillator coils weren't a matched pair, then you've done very well to get such good results adjusting the tracking by ear. Lots of fiddling about with trimmers, padders and signal generators is usually necessary to get this right.

Looking forward to seeing the full circuit!

Cheers,
Neil
