KM1P MA 3550300.3 -0.007 1.97E-09 Late report from Joe.   

Thanks for participating  in the first "Sudden FMT" (Clint's phrase). I'm very pleased with the turn out considering the very short notice. The noise level was high, but more importantly the ionosphere was fairly stable. The K index at 00:00 UTC was "0", and you don't get much better than that. I would have expected more Doppler to the West, as the West coast was still in Sun down phase.

I notice that most of the reports are centered around my posted TX frequency, so I've got to think it must be close. I still have a drift problem that I have not completely resolved. My posted frequency is the average for the period. The software took readings every 5 seconds. So if you averaged your readings, you were probably closer than taking a spot reading. A spot reading in the middle would have been good however. If your reading was more than .04 Hz off, we will blame it on Doppler hi hi hi. It will be fun to see if the Doppler Gods will let this weeks top five repeat next week. 

I would like to think Joe, (KM1P) for helping me get my act together for this first "Sudden FMT".

Equipment used for this FMT:

FT-920 at 60 watts, 80 meter cage dipole.

The next FMT will be Wednesday night April 4

    10:30 PM EDT 

    9:30 PM CDT

    8:30 PM MDT

    7:30 PM PDT

    02:30 UTC


The 80 meter run will be first, followed immediately by the 40 meter run.

80 meter frequency will be near 3550000 Hz

40 meter frequency will be near 7055000 Hz
