Rat own, as they say. I use a cheap B&K Sweep/Function 
generator and a Textronix 7000 series scope. I've used the 
sweeper method with several receivers and it is my method of 
choice to align them. I have not yet tried this method on a TRF, but 
I don't see how it can not work with that either. It will be interesting 
to see what I get with the TRF.

As Bob says, the secret is to sweep VERY slowly. If your scope 
doesn't have a long persistence phosphor, set the scope brightness 
to as bright as you can and still have it in focus, and turn out the 
room lights. Use a flashlight or similar to see the adjustments.
