[time-nuts] FMT -- bad propagation, but still fun

We did the Frequency Measuring Test last night. It was a small
multi-multi effort this year, with Daun, N8ASB and I setting up
hard-core stations, and Mike, KA8ABR doing a more basic measurement but
still using interesting hardware -- an SDR-1000 software-defined radio
that used a PC sound card as the ADC.
Conditions here in Dayton weren't good. We had weak but solid signals
on 80M, 40M was a real horror show with weak signals and lots of
interference from an SW broadcaster on frequency, and on 20M we didn't
hear a peep. Mike, WB8GXB, operated from his house and he did hear
signals on 20, but he has a triband beam up about 90 feet, so his
signal-catcher was better than ours.
I haven't fully processed the data yet to get final results, but I have
put a couple of screenshots up at
http://www.febo.com/time-freq/fmt/fmt2004.html. They show the offset
between my local reference tone (derived from an Rb standard) and the
W1AW signal.
