Yep - I use that all the time. The extra challenge was to put
time-stamping information in a data file using Cooley's file
headers
http://alumni.media.mit.edu/~jcooley/gr_experiments/experiments/gr_header.htm
that uses a header-size and data-size that can't just
be skipped over w/o everything getting out of sync.
Anyway, mission (mostly) accomplished - and being able to embed
information like decimation, center frequency, time of day, gps
position, etc is pretty handy.
