John,
It's good to see you are still alive and well!
Your idea of networking receivers around the world reminded me of the
Universal Digital Reciever (UDR) Project at Ohio State University, under
Prof. Grant Hampson. In looking at my bookmarks, I have
Alas, the link is no good. So a Google search of
"universal digital receiver project"
(you must include the quotes) yields a cached version of the page that was
good as of Nov. 25, 2004. The page tells more of the receiver hardware and
not much information about the software and networking. It was this
hardware that inspired the SDR-14 by RFSpace ().
I thought you might find it interesting and maybe it has some leads into
networking multiple receivers. I think this would be a very cool project.

Subject: [softrock40] softrock40 on the internet!
First I would like to say how impressed I have been with the little
SoftRock40 and the PowerSDR software. It has been a long time since I
have worked HF and this has really got me interested again. Thanks to
everyone who has put this together.
I have been thinking about putting the SoftRock40 on the internet with a
simple server reading the I/Q signals and serving them to clients that
connect (limited by my uplink speed). What is interesting about this is
that each client can then independently tune across the passband of the
receiver. Imagine a whole network of these little receivers around the
world. Want to check out the conditions on 40 Mtrs in Europe - just
connect to one in Europe and tune around!
I am a Unix/Linux/Java software engineer by profession and have good
development systems for these environments. I do not have any Microsoft
development systems - note the email address ;-).
I have downloaded the Linux code and am currently working on this to use
a socket connection to receive the I/Q data, and also looking at
implementing a GUI interface - possibly in Java.
Would anyone be interested in helping with this development? In
particular I would be looking for someone that would be prepared to look
at the PowerSDR Windows code to modify it to get the audio data from a
socket rather than the audio device or a Wave file.
let me know what you think and if you can be of any help.
