I'm one of the folks wanting to use USRP/GnuRadio for amateur radio
astronomy. Nice to see you
"on board" with the GnuRadio project. I actually paid a tourist
visit to the VLA a couple of years
ago, and bumped into one of your public-education folks.
I also just got my copy of "Synthesis Imaging in Radio Astronomy II"
didn't I see your name in
the credits?
There is a fair number of us tooling up to use USRP/GnuRadio
combinations for amateur
RA work, and it's good to see an increasing number of professional
radio astronomy
types joining the "GnuRadio" revolution.
I built an agile receiver a couple of years ago, but the spectral
bandwidth sucked, so I waited patiently
for the USRP to come to fruition. My winter project is to get my
USRP working to at least the
same degree of functionality I had with my receiver
(http://www.propulsionpolymers.com/radioastronomy/
seti_receiver.pdf). My primary interest is actual "conventional" RA,
but the spectral capabilities
were interesting to the amateur SETI crowd, which is how I slanted my
paper.
