But something not right about the phase/timing at Forest. These
repeats will not stack. May explain the lack of repeatability seen
at 17470.1 Hz.
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...
