VLF and LF
« on: October 04, 2019, 1824 UTC »
I've been listening to VLF and LF transmissions today and I am trying to identify some of the signals.  NAA. NML, and NLK seem pretty obvious.  However I am hearing digital broadcasts on the following frequencies that don't seem to appear on any of the lists.  Is anyone else seeing transmissions on these frequencies, or maybe I am just hearing local RFI?

22.75 kHz
45.5 kHz
68.25 kHz
91.0 kHz

One list mentioned that there may be a station, WH2XBA/4, Stanfield, NC, on 45.5 kHz.

Do you have another rig to see if it hears them too?
Conveniently located near Vincennes Indiana.

I did check a nearby Kiwi and they weren't there.  I've pretty much come to the conclusion that they are EMI from somewhere in the shack.  Thanks for the idea.
