The results of the first MVUS Frequency Measuring Test are now available
at http://www.febo.com/pages/mvus-fmt/index.html (click on "October 2007
Results").  There are also pages at that URL describing how we generated 
and measured the signals.

Nineteen people submitted measurements, and they show just how well it's
possible to measure HF frequencies if you're slightly crazed.  We had
numerous readings with errors less than 1x10e-10.

We chose winners based on the average offset of their measurements,
divided by the number of measurements submitted (to give credit to those 
who are both fast and accurate).

The clear winner was Connie, K5CM, who had the lowest average offset by
almost two orders of magnitude, submitted fifteen measurements and
thereby ended up with the lowest weighted offset by an order of, and 
tied for having the single best measurement.  Only one of Connie's 
fifteen measurements was more than 1x10e-9 in error.  Connie wins the 
grand prize, a certificate for any TAPR time and frequency product. 
Congratulations, Connie!

We awarded three runner-up prizes to Jeff, W3JW, Bill, VE2IQ, and
Martin, VE3OAT, who all had weighted offsets in the low 10s. All three
did a great job.

Finally, we wanted to recognize that folks west of the Rockies had a
special challenge receiving our modest signals from Ohio. So, we are
giving the "DX" award to Richard, W5UFZ, who managed to turn in an
average offset in the 9s despite the weak signals heard in Arizona.

Jeff, Bill, Martin, and Richard all win certificates for an ARRL
Handbook or equivalent value ARRL publication.

Thanks to ARRL and TAPR for their generous prize donations, and
congratulations to the winners -- and to everyone who entered!
