While I'm still on a roll with high stability off-air monitoring, here is a plot of the one remaining 100kHz transmission, from Anthorn, taken overnight. It has been reported by a few amateurs that this is exhibiting a 1 PPB frequency error, and that is clearly visible on my plot. The rest of the wobbles are multipath. Although a pulsed signal, when filtered to a narrow-enough bandwidth a stable spectral line at [exactly] 100kHz appears. There is some quite spectacular fading Andy G4JNT |
