Rick,
If you go to http://www.classaxe.com/dx/ndb/rna/, select all the types,
enter frequencies between 10 and 99 kHz, and specify Last Heard in a
year you will find a good number of VLF stations listed with callsign
and frequency. An even larger listing can be found by doing the same at
the Worldwide site http://www.classaxe.com/dx/ndb/rww/. Good URLs to
help identify sources are at http://www.vlf.it/trond2/15-20khz.html,
...20-25..., etc. Most of these signals are relatively wideband FSK so
they show up nicely on panoramic displays, even when below the noise
floor - Jay submitted a nice one to this list that is archived 3/4/10.
Particularly strong signals come from Navy transmitters NAA,24 kHz,
Cutler, ME; NLK, 24.8 kHz, WA; and NML4, 25.2 kHz, ND. Also very strong
in the morning is NWC, 19.8 kHz, West Cape, Australia. That fits within
your 24 kHz current passband. But if you can tune higher that's where
most of the signals are.
