KM1P MA 18073555.640 0.090 4.98E-09 Was able to get the early 17M test captured automatically ... I was at the playground with my kids at the time.
W3CSW MD 18073556.090 0.540 2.99E-08 Bill says, The 17 meter sig was right at MDS (-127 dBm) on your early run but neither 17 or 20 meters was heard later.  Both the 40 and 80 meter signals were S9 with QRN.
W1PW AZ 18073556.582 1.032 5.71E-08 17M sig 559 in your early run; nonexistent in your later run   20M sig 339 as you started; disappeared to 'imaginary' by key-down time. 20M measurement is almost imaginary!   40 M sig 589.  80 M 579  All measurements were made with only my Icom 756-pro II, my ears, and my clock.

W6OQI CA 14055753.760 0.240 1.71E-08 Signals were good on 20, 40, and 80.  The 40 meter signal had some close QRM but the 20 Hz filter on the 3586B took care of the QRM.  The signals on 20, 40 and 80 had a lot of Doppler shift as is to be expected here in Southern California.
W1PW AZ 14055755.208 1.688 1.20E-07 17M sig 559 in your early run; nonexistent in your later run   20M sig 339 as you started; disappeared to 'imaginary' by key-down time. 20M measurement is almost imaginary!   40 M sig 589.  80 M 579  All measurements were made with only my Icom 756-pro II, my ears, and my clock.
N6TP CA 14055755.736 2.216 1.58E-07 I did not hear the 18 MHz signal at all. (Solar Flux=70 A Index=37 and K=5)   20-Meters  The signal rose up from the noise level to S8.  40-Meters S8 to S9.  Good signal.

Don (SWL) NC 7055456.264 -0.057 8.08E-09 Heard about this from Joe, K9HDE, on ndblist. Using USRP/LFRX (www.ettus.com) with MFJ-959B and custom GNU Radio software. Couldn't find you on 17 or 20 meters.

K6YAZ CA 7055456.200 -0.121 1.71E-08 Stuart says, Early 17 test buried in the noise; unable to get good reading in 20 Hz B/W. Later 17 and 20 not heard at all. 40 and 80 not too bad on peaks, but a bunch of Doppler. Will this dry-spell ever end?

WB0UIR AZ 7055456.560 0.239 3.39E-08 Hank says, Simple setup here. I use a National receiver and a HP counter.
W3JW VA 7055456.570 0.249 3.53E-08 Jeff says, Did not get to make measurements on 17 meters or 20 meters due to poor propagation. Heard a few CW characters on 17 meters early run, but then sig faded out never to be seen or heard again (including the late 17 meter run). Likewise not a peep heard or seen on 20 meters.The 40 and 80 meter signals were of medium strength but the SL waterfall plot was very "wide" (or spread out--- there was not a good identifiable carrier line) (what I would call an "active" doppler plot on both bands). This kind of plot is not usually associated with good readings.

KD2BD NJ 3555386.463 0.204 5.75E-08 John says, Thanks for another opportunity to give my homebrew FMT equipment a workout! Your 80-meter FMT transmissions were copied beginning at 02:52 UTC on 24-May-07.  Signals were moderate to occasionally strong, with less severe fading than last week despite the much higher K-index (5) this week.

The K was high and Geomagnetic storms were at the G2 level. These conditions not only encouraged Mr. Doppler to to show off his stuff, but also lowered the already low MUF,  significantly reducing the number of readings on the higher frequencies. 

Don, from North Carolina with his first readings in the FMT, managed to elude the Doppler and read to HR status. Great start Don!

 

 

Honor Roll: (.1 Hz or better on two bands or more)

Transmitting equipment used for this FMT:

A HP-Z3801 GPS clocks a HP-3336B. A small 10 db transistor amp follows and drives a 12BY7 / pair 6146 in a TS-830. Then to a Drake L4B at 300 watts output except on 17 meters where the power is 75 watts.

Antennas:

80 -  Cage Dipole (favors East, West, and North)

40 - Dipole (favors East, West)

20, 17 -  4 element SteppIR in Bi Direction Mode (East/West)

 

As a double check on the HP-Z3801 GPS, I measured WWVB using the HP-Z3801 and HP-3586B for a 3 hour average, and got a reading of 60000.000002 Hz.

 

As suggested by Joe, we will probably go back to 30 meters and drop 17 meters until conditions improve.

 

Thanks to all that participated.
