Transmit frequencies in Hz



    Wednesday evening run

     80 Meters - 3578222.327  ( 9:15 pm CDT)

    40 Meters - 7078104.782  ( 9:00 pm CDT)

    20 Meters  - 14057169.707 ( 7:30 pm CDT)


    Thursday morning run

  160 Meters - 1845323.283 (6:45 am CDT)  11:45 UTC  

    80 Meters - 3579186.124 ( 7am CDT)

    40 Meters - 7079210.858 ( 7:15 am CDT)


W6OQI West coast run

    80 Meters - 3566999.685 (10:20 pm CDT)

    40 Meters - 7066998.847 (10:00 pm CDT)



The K index started out at a 3, and by the time the FMT was over on Thursday morning it was up to 4.  The comments verify, this made for poor FMT conditions. 


The distance award this FMT goes to JF1VRU, and 7L4IOU, both in Tokyo. Shintaro copied the 40 meter run, and Hisami copied the 160, 80, and 40 meter run. 



Thanks to all that participated.

N8OB OH It wasn't my evening on the radio.  No 20M signal at all and I couldn't lock in on 80M.
W2FD WPA Thanks to both of you for your efforts.  Noisy band conditions on most bands and very weak 20 M. signal here.
W6OQI LAX K5CM was S8 while aiming east and S9+10 while aiming west on 20 meters, S2 on 40 and S5 on 80 meters.  There was the usual Doppler movement plus some extra on 40 meters.
JF1VRU DX I am using TS-830 + Home brew Digital VFO. Thank you.
WA2DVU SNJ 20M No sig, 160m wild guess!  Sig in noise.  WWV run 2 error was about +200 mHZ at 1145z and about +700 mHZ at 1230z. I did not this to measurements. 73, WA2DVU Cape May, NJ
W9ZB IN 7MHz and higher were just about dead here by 11:00 EDT. 160 was open, but didn't copy anything here from the 5 call area.  The 3.5 and 7MHz morning runs were more readable, but with heavy QSB and phase shifts.  A challenge, but thanks for the fun, Connie.
WA4FJC VA I used a Trimble 10 mhz reference to a HP 3586B.  I also have a Kenwood TS 850 on the same antenna.  The 20 meter signal was very weak and not heard at all on the kenwood.  The 40 and 80 M sigs were fai with QSB.  The 160 m signals were not heard here in VA.  The Wed am 160 m signal was heard but not copyable.  The 80 and 40 m sigs were 599+.  Tnx for the run.  Gordon
KMZ KS Thank you Connie and Marvin.  The first 20 meter signal was not heard.  The second was just below noise level so my reading is probably way off.  The 40 meter signal was at noise level.  The 80 meter signal was 20 over S-9.  West Coast 40 meter signal was just above noise level.  80 meter signal was S-7 to 20 over.  Next morning 160 meter signal was very strong, 40 over.  80 meters was also 40 over.  40 meters had doppler with a signal strength of S-5.
WA1ABI RI Very poor condx for evening run. Nil on 20, weak sigs on 80 and 40. Morning run better. Nothing by ear on 160m, but Spec Lab picked up a line. Fair sig on 80m, good copy on 40. Tnx Connie, tnx Marvin. 73
N3FG EPA No signal heard on 20M.  TNX agn for a fb event.
N5LUL WTX 20M was very light copy. K5CM 40 and 80M signals averaged S7+. No copy on W6OQI 40M, yet 80M was S3-6.   Brad
W4AVO VA No sig on 20 or from Calif. IC756p3 + SL2.7b20. Tnx Connie.
W9TJ IL My 20 mtr is a WAG.  No identification either east or west but west sig hit a few short bursts.  40 mtr S9+30 some doppler short quick fades with phase run.  80 mtr S9+30 short quick fades with phase run.  West coast sigs vy poor with 40 there abt 40% and 80 abt 20% copy.  Thursday sigs were all good with doppler and phase run on 80 and 40. Thank you again for the chance to participate.
K5CM OK Good signals on 80 meters, but Marvin's 40 meter signal just happened to be on some sort of digital noise source. Still came up with a reading. Thanks for the West Coast run Marvin.
W0PHD MN a lot of QSB on both the 40 and 80 meter Wed sigs was not able to hear/see W6OQI on 7067 the 40 meter run #2 was weak and QSB
K6APW/7 OR Strongest signals K5CM on 40M and W6OQI on 80M, weakest W6OQI on 40M, in and out of my noise. Slightly modified correction algorithm, maybe better, maybe worse, certainly different, with decimal point calculations way past reason!
AA8K MI First 40 meter run was -85 dBm.  First 80 meter run was -70 dBm.  20 meter band had no signals; went out to see if my antennas were still up.  Flex-Radio SDR-1000 and Spectrum Lab.  AA8K
K7TT WWA 80M had very high noise here ... and couldn't find the signal on 160M run 2 here. 20M was a strong signal here. 20M West was better but just slightly over your East signal. A lot of what I guess is atmospheric movement of the signals making it necessary to use averages.
KD2BD NNJ Connie's 80 meter signal was quite weak with frequent fades during the evening run.  The Kp index at the time was 3.  It had been hovering around 0 for several days before the FMT.  Talk about timing!  I stayed up for Marvin's transmission, but didn't copy it.  Consider my entry a ballpark measurement due to the weak signal conditions.
KA1BQP RI Very weak signals except the 40 am run. No copy at all on 160 or 20. I had to rely on spectrum lab for the two west coast runs as well as 80 am. Tnx Connie and Marvin.
N7EP WA One of the more difficult FMT's.  Lots of doppler and weak signals. I'll be pleased to be within 0.5 Hz on any of the frequencies.
W6IHG VA 20m gone by fmt time. very weak signal, then operator error lost all readings. So best guess data was from dial calibration. Only band I had time for. Oh, well, next time. Jerry
K6OQK LAX I missed the 20 Meter runs but was able to get in on ALL the others.  Wednesday night's 40 and 80-Meter runs, which were still in critical hours, had a lot of Doppler by the time they got to Glendale, CA. The early Thursday morning runs were better.  Getting up Thursday morning at 4:15 Pacific is not a problem for me.  Thanks to Connie and to Marv for another great round of FMT's.Burt, K6OQK
W3JW VA Good signals on all runs except 20 meters. AT first I saw no signal at all on the 20 meter run. Changed over to my inverted-L antenna and picked up the faintest trace I think I have ever seen on Spectran. By then you were into the continuous carrier part of the transmission and it went away at the right time (as you rotated the beam)--- there was no possibility of a CW identification at the level I was receiving.
AF9A IN Connie, pretty good signals on 80m (Wed. night).   Heard nothing on 20, only a couple CW characters from your call on 40.
K1GGI EMA Nothing heard on 20, the best sigs were only S5 or so. Nothing heard on 160 either, but took a chance and recorded a few minutes, and Spectrum Lab found something. Wonder what it was. Anyway, another fun fmt. Thanks Connie and Marvin.
7L4IOU DX Hi Connie Reports are took up from the Waterfall. There is no proof, it was not Audible except 40M. I will try again at next run. Than you very much! 73 Hisami sri 20M wev file was clashed.

Transmitting equipment used by K5CM for this FMT:

A HP Z3801 GPS frequency source clocks a HP-3336B. A 10 db transistor amp follows and drives a 12BY7 / pair 6146. Then to the final amplifier, a Dentron 2500 running 300 watts out on 80, 40, and 20 meter AND 500 watt out on 160 meters.  There are no mixers or any device in the chain of amplifiers that might impact the accuracy of the GPS frequency source.  As a reality check,  I periodically log the frequency source against WWV and other GPS referenced sources.  I monitor each transmission with a completely separate receive system to look for any instability or short term drift. The separate system is not locked to the GPS transmitting system, but to another GPS source.

I typically see considerably less than 1 mHz difference at 10 Mhz when comparing  two Z3801's over a 10 second period. 



160 - Sloping dipole form top of 170' tower. Favors East, West, and North.

80-  Dipole - A 3.5 foot cage made from four wires in a box shape, sloping down from South to North (favors East, West, and North)

 40 - Standard Dipole hanging between two 80 foot towers. (favors East, West)

 20 - 4 element SteppIr 




Current W6OQI FMT transmitting equipment for this FMT:



My Transmitting setup consists of a HP Z3801 clocking a HP 3336B which drives a Johnson Viking I transmitter, the output of which is attenuated by a 6 db attenuator, to then drive an Icom PW-1 amplifier to about 500 watts. The antenna is an inverted Vee which favors north and south from the Los Angeles area.








Note: Because I put the results up quickly, there will be mistakes, so don't hesitate to point them out quickly.
