[Lowfer] 14.88 kHz VLF Alpha station

[Zack Widup]

Interesting. I wish I could put up my AMRAD e-probe antenna where I live
now. I have used the Airspy Discovery HF+ SDR unit to receive on VLF
through MF frequencies and it is an excellent receiver, the best SDR module
for that range that I own. I never tried to receive the VLF alpha stations
with it when I had the e-probe up before, but WWVB on 60 kHz was always
banging in day and night.
