That would work if you can sweep slow enough. The crystal rings too
much with a 60 cps sweep speed.

The typical 60 Hz sweep rate is way too much even for the non-crystal narrow
selectivities of the HQ-180. I had to use an old and battered Wavetek with a
slow sweep (just a few Hz) at the 60 KC IF freq, to align a reasonable
compromise between the CW narrow peak and a decent symmetrical AM bandpass.

The problem was not ringing, just failure to respond at all in the short time
of a 60 Hz sweep. 73, Mike K.
