[Lowfer] VLF signals

[Eric Smith]

Hi, Garry,

Rank noob here regarding VLF .. so please take it easy on me .. but is
there such a thing as a directive antenna at 12 kHz?  I would think it
analogous the (non-) directional nature of a bass drum at low audio
frequencies ...??

Perhaps it's off now or has a directive antenna aimed elsewhere. Also saw a burst on 21.1 kHz. In the evening that would be from one of the RLS transmitters but here in the morning signals come in from the Pacific so think it's RJS instead, located in Vladivostok. Can't see the signal on the KL7L grabber because its present tuning range doesn't go that high.
