What about the canadian stations? These are in the shortest distance
to EU and will become a very important factor in some months when
the QRN levels decrease. Are there already stations who permantently
monitor the dreamers band (not the whole VLF) with a suitable RX
system? Means, not only copying the ALPHAs by ear but having a SLOW
QRSS/DFCW window where DFCW-600 or DFCW-6000 can be displayed. Here,
it makes no sense to monitor the ALPHAs and 8,97 kHz in e.g. 4 Hz
FFT bandwith, what we need is 4 mHz! So, that one DFCW element takes
10 minutes. Another important step is to have a STABLE soundcard
sample rate. This is well performed in the latest SpecLab version.
Alternatively a GPS synchronisation or so is necessray!

What do the canadians or US stns think about that? Any REAL interest?
I have the necessary frequency stability/accuracy either already in
place or easily arranged and I'm certainly interested, but
unfortunately I live inland about 1000 miles from the East coast of
Canada (the best Rx location would be somewhere around St. Johns
Newfoundland). Nevertheless, I'll see if I can receive the Alpha
signals for a start. I've been monitoring your experiments and you
guys have me all excited about this VLF stuff!
