I have read a bit about the BPSK and CCW modes that ve2iq has worked on.
It is very cool, but I have a somewhat simple question: why are people
working on building audio A/D boards when almost any modern sound card
(approximate cost $30-$50) can do the same job?
I have been experimenting with doing "cheap dsp". On my Pentium-133mghz
computer, I can easily grab 16 bit sound samples at 9600hz and perform
overlapping all-floating point ffts 1024 long and still use < 10% of the
total available CPU time. Admittedly, not everyone has a Pentium, but
many of us certainly do.
I have been experimenting with making a Unix program (I run FreeBSD
at home, but the results should be portable to linux as well) that
duplicates the functionality of HamComm, which appears to be a fairly
neat program. I'd also like to work on BPSK too. Is anyone else here
interested in low power digital experimentation?
