[Lowfer] VLF Alphas

[Garry]

The so-called Alpha transmitters have been coming in well of late, 
morning and evening 
(https://en.wikipedia.org/wiki/Alpha_%28navigation%29). Attached is a 
copy of the 3 main transmitters here, evening on top, morning beneath. 
The number at the end of "alpha" stands for the number of beeps heard 
via audio monitoring. Laurence's grabber (http://kl7l.com/Alaska.html 
and http://kl7l.com/fast00000.jpg) usually shows a 4th alpha at about 
12.091 kHz but for some reason I haven't been able to copy it. Wonder if 
it produces 4 beeps?
