Excellent results, Lyle!  I didn't know the exact freq at the time I
started up.  Eventually the Epson oscillator stabilized at 6776.7925 Khz.
When no one responded I thought about publishing the exact freq and the
run length, but I guess it wasn't necessary.  Not bad communication in
terms of miles per milliwatt, eh?  I can receive it locally with a
delay of about 1 msec using GPS sync.  I'll leave it running for a
while.

Thanks for the report,
Bill VE2IQ
