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,
