[Lowfer] Spectrum Lab as LORAN receiver

[Lyle Koehler]

Thanks for the explanation, Stewart. The advantage of the SSB technique is
quite significant. But I'm still having trouble "zero beating" the audio
carrier. As far as I can tell, the smallest frequency step for the local
oscillator in SpecLab is 0.1 Hz, and that doesn't seem to be good enough
when I use large numbers for signal averaging. I have played a little with
the sampling rate calibration, which may offer much finer resolution, but
it's hard to tell when the settings are correct. And if I finally get it
right, the darned receiver will drift :-(
