Excellent. As it turns out, mine is driving a 28KSR. One demodulator is the
little FSK board I'm building for the list members, and the other is an
experimental one running on an Atmel microcontroller doing the work entirely
in software. I'm still amazed a $2 chip can do enough math to sample and
analyze that much data fast enough to keep up, so I'm willing to forgive it
an error now and then.
