An impressive idea - sounds a bit like radio astronomy on LF, using an
One problem I see for a practical implementation is the internet
connection - last not least because on some quiet "remote" sites there
is no internet at all, or only through a slow modem connection. I played
with the windows socket services some time ago, trying to get a reliable
audio link in "almost real time" running, but got entangled in red
tape... it may be simpler these days, but I honestly haven't got a clue yet.
For a start, we either try to exchange the audio samples as simple
decimated audio files (via manual or automated cyclic FTP, etc), or find
someone with in-depth experience in WAN / internet programming.
Another, possibly simpler "local" approach which would not rely on the
internet, is using cheap FM links to combine signals received from
various receiving sites separated a few dozen kilometers from each
other, and use a PC / soundcard with multiple inputs. This would allow
almost-real-time reception, good for two-way CW attempts ;-)
For the test recordings, which file format would you prefer ...
bandwidth / sampling rate, complex or real sample pairs, etc ?
I wanted to add a decimated audio logging feature in the WOLF GUI,
possibly using the JASON file format (which is supported by at least two
other programs already), or something in that style.
The next chance to make a few recordings would be on Thursday evening,
or next weekend, though the "QRN forecast" doesn't look very promising.
