[Lowfer] VLF OT

[Graham]

Hi Laurence,

25.0, 25.1, 25.5, 23.0, and 20.5 is the sequence. Call signs are sent 
starting at 6 minutes after hour starting with 25.0, then stepping 
through the other frequencies over the next 40 minutes or so.

Scheds are not every hour and different transmitters take their turn at 
different times.

The transmission at 06 UTC is the one I haven't been able to identify, I 
see it on my grabber but it is not strong enough to ID on 25.0 kHz.

cheers, Graham ve3gtc
