I'm probably one of the few people on this list who cares, but here's an
interesting plot of total power data taken
at declination -29degrees, across 22 hours of right ascension. The
chart shows data for three days, and an average over those
three days. The main response is due to Sgr A--a s
Where can I find python code to demodulate FSK? I am
using it with the DBSRX card.

Hi everyone,
I know I promised a spec file for GNU Radio, but I have been busy
lately. Here is however the inital version. I still have to split it
into several sub-packages, but it works
ftp://open-gnss.org/pub/gnuradio/gnuradio.spec
Give it a try, and send me feedback if you want to. The spec

Tim,
Thanks for your interest. Sorry it took so long to respond, I've been rather
busy.
It would be worthwhile to have a solution that works over variable bit-time
products, but for starters, let's say the BT product is 0.35. The modulation
index is 0.5 (which I believe is true of all GMSK i

There is overlap only in the sense that each project implements many
similar DSP algorithms.
