| AA6LK | SV | CM98kw | Tnx Connie for running the event. 73, L- |
| AB2UW | NLI | FN30lu | Thanks for your efforts in running this FMT. |
| AB4RS | VA | FM18hw | Did the first 20m run, then started watching a movie with the family and forgot about the rest until it was too late. 20m East was very strong, but 20m seemed a bit more stable for me so that's what I used. |
| AC2PL | ENY | FN30cv | First time FMT. 20M dipole into IC-7300 CW USB narrowest filter setting. Precal with Leo Bodnar GPSDO fed through attenuator into antenna port, radio 1.1 Hz high. During callup, adjusted VFO using iphone, recorded with spectrumlab. Thanks Connie. |
| AC6SL | SCV | CM87wd | FMT on K3 Main rcvr, GPSDO signal generator on sub-rcvr, observe Lissajous for zero beat. |
| AF9A | IN | EM69wv | 1830Z signal on 20m east was about 10dB above the noise at best (Mercury panadapter FFT bin width 2.9 Hz). Nothing heard on the west ant. 20m at 0100Z started out great being ~30dB above then noise then faded fast . 40 and 80 good! Tnx Connie! |
| AJ5P | MS | EM51kr | Using different rig this time, FT-818 and Fldigi. Lots of QRN. 20 meters barely audible, used the east run. |
| AJ7F | WWA | CN98ab | This is the second FMT that I have participated in, the first one was April 2019. My setup is a Trimble Thunderbolt disciplined Flex 5000. I set the cw filter to a 10 hz bandwidth at 200 hz. The audio was sent to Visual Analyser FFT software by VAC. |
| K0MZ | KS | EM28ix | Thank you Connie for doing this FMT. The 20 meter signal at 20:03 was very weak, perhaps S-1. Your 40 meter signal was nice and strong, very clear 20 over. Your 80 meter signal was very strong, 20 over with some doppler. As usual I matched pitches by ea |
| K0WM | CO | DM79jt | Great signals on 20 and 40 meters. The propagation on 80 meters was a little wobbly as usual. Thanks to Connie for running another great FMT-they are really fun! |
| K5BDM | OK | EM16 | oven timebase freq counter averaged 7 readings |
| K5RKS | OK | EM15 | Good FMT run. Early 20m pointing west was very erratic -- evidently due to doppler |
| K6BZZ | AZ | DM33xb | RSP-1A SDRuno |
| K6FOD | LAX | DM04 | HP3586B + HP3336B, both Trimble Thunderbolt-disciplined, outputting to oscilloscope for Lissajous display. Also ran GPSDO-referenced SDR + fldigi backup. 20m very difficult, 40m easiest, 80m in between. Big thanks to Connie for another great FMT event! |
| K6OQK | PAC | DM04ud | Method of Measurement - see: http://www.k5cm.com/k6OQK%20FMT%20NEW.htm |
| K7NG | ORE | CN73ui | The 20M late signal was so weak I wasn't 100% sure I was hearing the right one. We'll see how fldigi does on signals that weak. 40M and 80M were decent strength ans smeared about 0.5 Hz. Using IC-7610 and external sound interfaces. |
| KA1BQP | RI | FN41fq | Good strong signals on all 3 bands. Tnx Connie! |
| KA5QEP | OK | EM15ni | Signals were good, but it's always up to the ionosphere. |
| KB2HSH | WNY | FN02nx | Outstanding signals into FN02nx. Thanks for the 2nd run, Connie, and thanks to N3CRT for the technical assistance in this...my 6th FMT (still lousy at it, but having fun everytime!!!) 73 de Buffalo NY....KB2HSH |
| KD2BD | NNJ | FN20xd | Strong signals with a Kp-index arouhd 1. There were 180 degree carrier phase flip every few seconds on 40. 80 was more stable. Didn't try to "outsmart" the ionosphere. Hardware details at: https://www.qsl.net/kd2bd/fmt-methodology.html |
| KD5MMM | STX | EL19ds | Hope to be close...73 all |
| KM6QX | EB | CM87 | Used Dipole, Flex-1500, SpectrumLab, and Fury GPSDO. Reported most likely peak, corrected for DDS offset. |
| N2GL | ORE | cn85kp | HP3586A signal level meter disciplined by HPZ3618A GPS reference. Thanks for the test. Maybe I have the reference hooked to the right instrument this time! |
| N2QLQ | SFL | EL96wm | My first ever FMT. No fancy equipment! Just my old FT1000-MP and an attic dipole. The 20 and 40 meter signal wete about s4 to5 over the noise..very readable. Used FLDigi and basic math, but may not be even close..still fun! |
| N3CRT | NNJ | FN20qv | 20m early - s7+ East - s3 West test- 20m late - QRM under the callup signal, no effect, E S9+20, W S6-S7 QSB - 40m - S9+10 - 80m early - S9+10 fades to S7, Flex 6400 FLDigi THANK YOU!! FUN! |
| N6RDR | ORG | DM13 | |
| N6SKM | EB | CM97BP | Thanks, Connie for giving us the same test at different times. There were 1/2 hz diffs between the pairs. Apparently the ionosphere was really moving! QSB was high, almost 1 hz variance on 80 meters. Good signal strength here for all tests. |
| N7EP | AZ | DM43dj | Thanks Connie, all signals were great into Arizona. The one minute key down makes it a bit harder, but still fine. |
| N7UTE | UT | DN40cq | |
| N7WS | AZ | DM42JH | Pretty much WAG on all of this. Propagation was iffy. Signal strengths were okay but QSB and sig quality were awful. I was really looking forward to this FMT but am serioulsy disappointed. |
| N8OOU | IL | em68es | Thanks for the extra transmission. Good signals on all transmissions. |
| N8TW | MI | EN82hh | |
| NF7R | NV | DM26so | Alerted to the FMT late so only 80M was attempted. Good sig. Used IC-7300 and FLDGI with computers sound card. |
| PA0PJE | DX | JO22LJ | 20 meter tx. unheard. Used RX: IC7610 locked to 10MHz Rb-standard. Ant: 2x20mtr dipole on 1st rx and MiniWhip (E-probe 30x50mm) on 2nd rx |
| PE1FJN | DX | JO32BL | Weak signal on my small antenna HyendFed at 5m height on 20m, but I got it. Used a SunSDR2 QRP calibrated using RWM 9996MHz, and SpectrumLab to plot K5CM FMT frequency, and average by the eye. 73 PE1FJN, Marc |
| VE2IQ | ON | FN15nt | 40M sounded great (S9+20dB) but computer didn't like it. |
| VE3GSO | ON | EN92ix | strong signals, strong QRN |
| VE3OAT | ON | FN25eg | Many thanks for this, Connie. As usual, another "interesting" experience. HI |
| VE3YX | ON | FN16fd | Used the drifty 870 again with the GPSDO stabilized sig gen as a reference. 20 m East signals were very strong here. The West signals were still quite good. I chose the late East 20 m run. Thanks again Connie. |
| VE9DAN | MAR | FN65td | Good practise -- should do this again in 2 months. |
| W2EMN | NLI | FN30ku | good signals |
| W2TX | GA | EM74se | KWM-380/Sound Card/Spectrum Lab. 41 ft vertical antenna. Only the afternoon 20M west transmission was marginal signal strength, all others were fine. Nearly 1/2 Hz of doppler spread on 40M signal. Morning and evening 20M data was in close agreement. Tnx! |
| W3JW | VA | FM17tq | Conditions were average. All signals S9+ except the West directed 20 M transmissions (which still produced good measurement opportunity!) Tnx es 73--- |
| W4IVF | VA | EM96to | Thanks, Connie. |
| W4VU | NC | FM06fb | HP3586B with QRP-LABs VFO/GPSDO. Tried to use Fldigi but not quite there yet. Thanks Connie! |
| W4WJ | STX | EM00mg | The Racal 6790/GM still on the bench. Zero beat unknown with GPS locked HP3336B. 20m early: -80dBm QSB to -110dBm. 20m late: -95dBm QSB to -130dBm. 40m: -55dBm QSB to -100dBm. 80m early: -47dBm QSB to -80dBm. 80m late: -50dBm QSB to - 80dBm. TNX Connie! |
| W5LAC | MS | EM51hh | |
| W6BM | EB | CM87uv | Thanks, again, Connie |
| W6OQI | LAX | DM04 | Good signals on all transmissions but with the usual multipath moving the frequency. |
| W7KPZ | ORE | CN84 | RSP |
| W7SLS | WWA | CN85qr | My first FMT. Thanks! If I get close, glad to share how I acquired and analyzed. - Scott, W7SLS |
| W7SUA | AZ | DM34rs | Thanks Connie. Fun again. I copied both early and late 20m just fine. I used my GPSDO, calibrated against CHU, and a combination of eyeball on the plots and TRIMMEAN() function. Thanks es 73, tom |
| W8NN | MI | EN82bk | Thanks, Bill |
| W8WTS | OH | EN91jj | |
| W9GR | SV | CM99mg | Got my dipole feedline repaired and reinstalled after the March blizzard took it down. It's important to have a working antenna for the FMT! Thanks Connie. |
| W9INE | CO | DN70gi | FLEX 6700 & FLDIGI. Good Signal Levels except 20MTR@0100Z was noisy. |
| W9MDB | IL | EM49hv | 80M - 0.3Hz deviation, 40M - 0.1Hz deviation, 20M - 1.0Hz deviation. Apache 100 w/GPSDO ref, two instances FLDigi one for Bodnar GPSDO tuned 500Hz below the FMT freq and the 2nd FLDigi on the FMT freq. Avg corrected by Bodnar avg. |
| W9TN | IN | EN60 | This time I stole an idea from K6OQK and made a Lissajous figure tuning indicator out of an old analog scope and an AF generator. This sped up signal acquisition during call up. Otherwise used the usual AM receiver heterodyne method with Spectrum Lab. |
| W9ZB | IN | EM69xp | Daytime 20M was in the noise here. Night run was better. 40M and 80M were strong. Tnx for this, Connie |
| WA1SXK | NC | EM95LF | Used Fldigi Freq. Analysis mode, used a GPS 10mhz Ref to calibarate my Icom 7300 before each FMT. My deviation was slightly larger on the 40m FMT. |
| WA2USJ | NLI | FN30bq | 73 Joe |
| WA4FJC | VA | FM08lf | Thanks Connie.Nice late sig on 20 M here in VA. |
| WA7BNM | LAX | DM04td | 1800Z East/West and 0100Z West 20m measurements within +/- 0.015 Hz. Measured frequency variation during 40m and 80 runs was +/- 0.7 Hz. Used Icom R-8600, Jackson Labs Dual Oven OCXO/GPSDO Fury and Fldigi |
| WA7X | UT | DN40cq | 20 meters early copied both E and W, on the 80 there was some QRM, sounded like a broadcast that came and went, interference? |
| WB6RJH | SCV | CM87WA | This time used an SDRplay RSPduo to monitor WWV and CHU while the Anan-100D monitored the test signal. As always, art as much as science in compensating for doppler shift. |
| WQ8T | MI | EN82gh | Thanks Connie. |

Transmitting equipment used by K5CM for this FMT:
A HP Z3801 GPS frequency source clocks a HP-3336B. The output is feed to a 10 db transistor amp which drives a 12BY7 / pair 6146. Then to a AL-1500 running about 750 watts out. 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.
I typically see considerably less than 1 mHz difference at 10 Mhz when comparing two Z3801's or a Z3801 and a Thunderbolt, over a 10 to 10,000 second period.
Antennas:
80 - Dipole. (favors West, North, East)
40 - Standard Dipole hanging between two 80 foot towers. (favors East, West)
20 - TH7 at 80 feet
