I use LSB for this reason, too, and had troubles with Andy's Hell 
until I twigged that a dot at the top of a series of symbols probably 
wasn't right.

As for using the frequency scale on Spectran or Spectrogram. I 
just wouldn't do it. The simplest way of calibrating your receiver is 
to put VFO 1 on 60.000kHz, adjust Spectran or your RIT so that 
the signal appears in a convenient place on the screen (say, 
600Hz), then switch to VFO 2. When the dial says 137.700kHz 
any signal on that frequency should appear at 600Hz on the 
screen. This assumes a 1Hz read-out of course, but it does 
eliminate all calibration errors and you don't have to set the receiver 
or Spectran to a wide setting to make it work.
