Hello Con,

Thank you!

The Alphas are currently off.

You can check it on my VLF grabber if you want, it is running 24/7: http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_VLF_Grabber.html

There is a grabber window (RSDN-20_F1) which shows the Alpha trace at 11904.7619 Hz. You can see it is OFF since 2 days. The lower window (wideband) shows the VLF spectrum, as received here in Heidelberg. There, you can see all 3 Alpha traces, if they are ON, at about 15 dB S/N, depending on daytime but always visible...

Good luck in experimenting down there :-)

73, Stefan/DK7FC

 Hello folks,

I am new to the group and have been following with great interest the VLF experiments. Congratulations to Stefan on such great DX (1000+km). This is really good stuff.

I have noticed in recent days that the Alpha stations at 11.9 and 14.8kHz seem to have stopped transmitting. I can normally hear seven stations but they have all disappeared. So I am wondering if propagation has taken a dive, or perhaps the stations have gone QRT?

Has anyone over there heard the Alpha stations recently?
