Subject: Unid non-LORAN transmission at 100 kHz ?
>At the moment is there a strong unid signal just below 100 kHz. When
first detected it could be best described as a very slow FSK signal
mark frequency 99.8 kHz / frequency shift 475 Hz ), after a short break
this changed to steady, but reduced, carrier at the space frequency, -
with non-regular spaced pulses of carrier at the mark frequency. This
later signal show after first examination some similarity to the earlier
reported unid pulses at 115.2 kHz. The pulses at 99.8 kHz has both an
audible and visible 100 Hz overtone,

Very likely, yes!!!!
Absolutely nothing here last 24 hours between 82.7 and 115 kHz.
