[Hammarlund] Crystal Filter Alignment

[k2cby]

I would be grateful for any more information on aligning the SP-600 crystal
filter, starting with the procedure for orienting the little arrowhead on
the dial (which never seems to be explained in the service manuals).

 

Although I have followed the standard 455 kHz and 3.955 MHz procedures
outlined in both the commercial and military service manuals with apparently
good results, I have never been able to square the results with the very
roughly described procedures for sweep oscillator alignment. Is there a more
complete description of the sweep oscillator procedure?
