Helly Terry,
The resistance measurement came up good. I hooked my 4' tuned loop antenna to it and received stations all over the dial. This just isn't a very sensitive receiver and needs a good antenna.
I tried to do the allignment by the book with the signal generator set at 460 khz for the IF. It acted like it wanted to work but just didn't behave properly. Set the signal generator at 230 khz (half of 460) and it tuned right up and works nicely. I can see why these have a reputation for being hard to allign if the IF spec is double what it is supposed to be. Being double what the tank is tuned for it will try to work but just not very well.
