Hi Jay,
Others (than me) may answer your question better. I just want to say
that i am happy that you improve your VLF RX :-) Maybe today or tomorrow
i will set up my new VLF Grabber here in Heidelberg. The system already
works on my PC, just the connection to the server has to be done :-)
I use a narrow band filter arround 9kHz. The ALPHA beacon @ 11,904762 is
attenuated arround 40dB! But the SNR is still about 10dB so the
(E-field) antenna seems to work very good here at this QTH. So, i could
add a ALPHA screen as well, to study these effects...
Best 73 and hpe you see me on VLF one day ;-)

Been monitoring / plotting the alpha stations over the past couple
weeks while working to improve the VLF receiving setup. The following
very slow 'selective fade' has been seen every night that I've looked
(4 times) so it's not a one off occurrence. Anyone care to speculate
on what would cause this?
