Micro PSK31 encoder

I've adapted a C version of a PSK31 data encoder to Microchip assembly
language for the PIC 16F87x micro and made a few improvements along
the way. Hams (and others) may find this device or simply how it
works, to be useful.
Details and the the source code are available here:

Cool. What's the data transfer rate and how does PSK31 compare to the
AFSK used in APRS?

PSK31 has a data rate of 31 baud, hence the name.
It's real beauty is the extremely narrow bandwidth it occupies as well
as the DSP processing gains and cool freeware available to decode it.
Good info here http://en.wikipedia.org/wiki/PSK31
I plan to experiment with some low power 2m DX testing later this spring.

A Guy I work with has developed another mose called Domino ex.
http://www.qsl.net/zl1bpu/DOMINO/Index.htm

A really amazing guy. He ran it on 2 laptops working through the sound
system, mic's, speakers etc. and can still communicate in a room full of
talking people.
