Just going to toss this out there in case it helps. One of the ways I have found to inject an IF signal is via induction (no direct coupling), thru the antenna, with the oscillator disabled with a small value cap across the oscillator section of the tuning cap and the tuning cap set as close to the IF as possible ... for a 460kc IF that would probably be AM at lowest setting (tuning cap fully meshed). By limiting the amount of induction, the signal generator can be set to produce a very low level output and the IF adjustments really can be seen to make a difference. I have double checked this method by using a conventional hookup afterward and I have yet to re-adjust after doing it this way.

Anyway ... just an alternative.
