W3JW VA 3550535.465 -0.008 2.25E-09   Antenna used for all measurements was a 260 foot long dipole (30 foot height) fed with 450 ohm ladder line and tuned by an automatic antenna tuner(PRIOR to each measurement period). 20M sig (7PM EDT) was weak to medium 80M sig was strong with moderate QRN 40M signal was strong with moderate QRN 30M sig was strong with deep fades moderate QRN 160Msignal was medium with heavy QRN (static) These conditions are inferior to those for the 18 APR test.Used Spectrum Lab software this week.(Primary measurement tool for 20M and 160M tests/secondary for others)
K9HDE IL 3550535.460 -0.013 3.66E-09 Was last week only luck?  We shall see.   20M Not available to listen     80M  Signal strength moderate, watery (multi-path?), reception quality    40M  1st half of run. signal strength strong, reception quality good   160M  Signal strength weak, reception quality average
AF9A IN 3550535.490 0.017 4.79E-09
KT6KT NV 3550535.440 -0.033 9.29E-09 No signal on 160 M, QRM on 40 M, no reading on 30 M
K8JQ WV 3550535.400 -0.073 2.06E-08
VE2IQ ON 3550535.400 -0.073 2.06E-08 Another great FMT experience - your signal on 20M was just barely audible - took me a while to find you - eventually got enough of your call on a QSB peak to confirm After filtering and taking some gain though, the freq plot wasn't too bad:
KD2BD NJ 3550535.400 -0.073 2.06E-08 Marginal signals combined with occasional static crashes and frequent fades made frequency measurement quite a challenge this time.  I'm afraid my results may not be as accurate as they have been in the past. Even though the K-index was fairly low, I saw quite a bit of symmetric Doppler spread on CHU prior to the FMT.  This is a bit unusual, since CHU normally reads low during the evening hours in NJ.  Propagation is tricky business! Thanks for another challenging exercise, and for including me in your FMT discussion group!
W1LE MA 3550535.360 -0.113 3.18E-08 Very low spread on 160M,  ARGO/PC w/ IC703+ and a active whip
W3CSW MD 3550535.360 -0.113 3.18E-08 Great FMT. Lots of QRN and QSB, but little to no Doppler noticed this time.
KM1P MA 3550535.310 -0.163 4.59E-08 First time I managed to do a measurement on 30M. Signal was very stable here ... much more so than 40M and 80M. 
WB0BBE CO 3550535.640 0.167 4.70E-08 Propagation was challenging this week.  LOTS of doppler on 80, lots of QRM on 40m, 30m dropped significantly after the CW portion, 160m was very week.
N6TP CA 3550535.733 0.260 7.32E-08 S9 Good signal on 20, S7 but above the noise on 80,  S8 on 40,  S8 Good signal on 30. I could not detect any signal on 160-meters. I saw just an occasional birdie that did not go away.  Thanks for the fun
K6YAZ CA 3550535.155 -0.319 8.97E-08 Stuart says - Good stable signal on 20 meters, 80, 40, 30 OK but not too strong, nothing on 160.

N8OB OH 3550535.800 0.327 9.21E-08 I tried a little different technique this evening.  Heard the signal on 4 bands but very weak on 30M and 160M.  Still lots of fun.  Bob
N5PWG TX 3550535.970 0.497 1.40E-07 20 meters -  No signal heard; heard San Diego and W3's and W4's   30,40,160 - weak signals.  80 - good signal
K6APW CA Fumbled... did not hear a station ID on 80M, measured a keydown signal of S5.  40M S6 to S8 with QRM.  30M S3 to S7 with sharp dips. Nil on 160m (just after sunset here)   I can really only do 1 Hz at bestů. Fun, anyway

As usual Mr. Doppler keep just about every one scratching their heads and saying that just couldn't be right. If only we could lock the Doppler to GPS, but then again, that's what makes it such a challenge. 

Several changes to the transmitting system this week. A HP-3336B clocked by a HP-Z3801 GPS was used as the exciter. This drove the 12BY7 / pair of 6146's in a TS-830, then on to the Drake L4B. I'm low on drive coming out of the HP-3336B so only 100 watts out on all bands. This system allows me to dial in frequency to the mHz locked to GPS. As a double check I measured all frequencies with my other system. I also checked the HP-Z3801 against WWV-20 which I can receive on ground wave. I should have more power for the next run.

I would like to thank Burt (K6OQK), Stuart (K6YAZ), and Marvin (W6OQI) for the help and advice on the HP-3336B.

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

Please let me know which day would be best for a daytime run (Saturday or Sunday). The time will be near high noon local Oklahoma time (1:00 pm cdt)

Thanks to all that participated.
