October 2007 Announcement

The Midwest VHF/UHF Society (located in Southwest Ohio) is pleased to announce that the first annual MVUS Frequency Measuring Test will be held on Saturday, October 13, 2007. There will be two transmission periods: the first at 14:30 EDT (1830 UTC), and the second at 21:30 EDT (0130 UTC Sunday). Transmissions will be on the 80M, 40M, and 30M amateur bands from Dayton, Ohio under the callsign W8KSE.

Here are more details:

Our goal is to transmit a signal known in frequency to parts in 10e-12 (i.e., less than 0.0001 Hz error at 10 MHz) and stable to a similar level during the course of the transmission. Frequencies will be measured at the transmitter site with a system capable of microHertz resolution referenced to a GPS disciplined oscillator, and will also be monitored by another station in groundwave range that can measure the frequencies with similar accuracy.

The MVUS Frequency Measuring Test is intended to supplement, not replace, the ARRL FMT.

Further information will be posted at You can also send email with questions or comments (or, after the test, your results!) to "".
