Such a shame! Obviously i wasted two weeks of nightly transmissions 
during the best time of the year to leave a message on a RX site that is 
not working properly :-(( I'm disappointed.
I remember i asked if the phase of the Alphas, JXN and HWU is 
reproducable or if it shows the same behaviour.
It seems that precision VLF stuff is not as easy as it seems in the 
first view...
This is why i run my Alpha  F1 (11904.7619 Hz) RDF spectrogram on my 
grabber...
