Hey everyone,

I think I have a semi-decent implementation of BPSK modulation and
demodulation (via a Costas loop). I wrote up some details about it at
http://web.mit.edu/imirkin/www/gnuradio/bpsk.html . It seems to work
with the script that I was testing it with, but I haven't actually tried
anything OTA or with any *real* drift and so on. This applies into the
gnuradio-core tree directly.

Hey - looks good - here's a plot of  0000 0000  1010 1010  0101...


I would be interested in using that with this description of psk31


to create a transmitter completely within gnuradio.
(currently I'm looping audio from linpsk)

Any better links to psk31 details appreciated.
