[Hammarlund] Re: Sweep Method for Alignment - ringing.

[Julian Bunn]

Hi Ken et al,

I have a followup question about the IF alignment with sweeps.

As you know, I was using this with success to align an HQ-110C.
More recently I have been aligning a Hallicrafters SX-62. This
has a crystal filter with "sharp", "medium" and "broad"
positions. It's not clear to me at all how to proceed with
the sweep alignment for the crystal filter positions. I assume
the basic procedure is the same, but are there any nuances
to be aware of?

Thanks!
Julian
