Method: I used this occasion as, uh, justification to buy another, um, "tool" - a HP3325A synth function gen. This time, I used a Marconi 2019 (RF synth) and the 3325A, both locked to HPZ3801A as references; used an FT-847 in AM/narrow mode to produce ~400Hz audio beat between the 2019 and incoming signal off a 5BTV antenna; displayed beat signal and output of 3325A on a dual-trace scope, and tuned the 3325A for minimum freq/phase difference between the two; used a Prologix USB-GPIB and an EZGPIB program running on a Vista laptop to initialize the generators and o'scope and to interrogate the generators after the measurement, calculate a result, and store it all to a file; was also running Digipan as a spotter, and GPSCon through a USB-serial adapter to monitor the Z3801A. I'm amazed the PC doesn't crash with all this stuff going on.
Soapbox: Exceptionally quiet bands this time, minimal atmospheric noise made for good measurements. Good signals all around, but WA6ZTY and W6OQY(80m) had the worst frequency/phase instability, no doubt due to the short distances involved. Thanks to the FMT gang who made it all possible. Nice, smooth handoffs between stations. 73, L

Method: Equipment setup: 1. 10Mhz TBolt GPSDO clocking a Motorola R2600 Service Monitor acting as variable frequency standard. 2. Radio is a ICOM 7000. 3. Antenna is a Scorpion vertical (screwdriver) mounted at 6 ft above ground level; tuned hamsticks as ground plane at 6 ft level. 4. Isolation of audio between radio and PC MFJ-1279J. 5. PC is a Dell D820 Latitude. 6. Audio analysis using SpecLab and Microsoft Excel Method: 1. PC sound card was calibrated with a 1Khz derived from the 10Mhz clock. 2. For 80Ms, tuned radio to 3.575 Mhz USB 2a. For 40Ms, tuned radio to 7.054 Mhz USB 3. Tuned the Motorola R2600 to match the radio dial plus 2200hz. 4. coupled R2600 and antenna feed; and feed the mixed signal into radio. 5. Audio out of radio included both the audio tones of the test signals and R2600 audio reference signal. 6. Using SpecLab, both tones were analyzed. 7. In SpecLab, multiple 50hz FFT bins were pre-setup to cover 400hz to 1200hz. 8. Processing was done in "real time" during the test. 9. An audio .wav file was generated during the test period for backup and post processing. The Math: (the same math process was done to the real time and post .wav sessions) 1 the FFT .txt output file was imported into Excel. 2. the R2600 fft bin containing the reference 2200 hz was averaged 3. for each fft bin containing a test signal, the averaged was determined over the time of the respective test time. 4. for each tone, including the R2600 audio reference, was corrected using the correction factor found during the sound card calibration. 5. for each test tone, the absolute difference was found between the R2600 audio reference tone and each test tone. 6. Because the Radio was set to USB AND all test tones were below the R2600 Audio Reference; 7. Each test “Frequency” is found by subtracting the respective test tone from the R2600 RF setting which is 2200hz higher than the radio dial. Notes: 1.Both the real time and post .wav analysis were compared and found to be within .01 hz.
Soapbox: I've participated in these ARRL FMTs for the past several years. Changing the time made a big difference in receiving ALL of the test station signals. All but one was above the noise floor, one was in the noise (almost none audible in headset and speaker) but there was enough signal for SpecLab to capture and process. I like the round table and schedule. It reduced a lot of radio tuning and variable standard tuning. In past FMTs this was most stressful when most of the test stations were below noise floor. The round table was excellent, the reception was excellent. I had several hams in the shack that wanted to learn how this is all done. It was smooth when one is not frantically tuning. Explaining each step to observers permitted a great experience for all. Thanks for this great event. Norm, AA7OO

Method: I used only Open HPSDR, Flex-Radio's PowerSDR, Thunderbolt GPSDO, and Spectrum Lab. I offset the HPSDR frequency about 500 Hz to make a tone with the HPSDR BFO, used PowerSDR to make a wave file. I played the wave file back and ran Spectrum Lab, noting the offset from the HPSDR frequency. Antenna: ground-mounted vertical 20 meters high.

Soapbox: Enjoyable as always. All 40m signals were loud and clear, S9+. K5CM was S9 on 80m W8KSE was about S8, and W6OQI was about 3 dB over the noise, but I was able to copy. The doppler had me getting the dartboard out for a few of these, we'll see how lucky I got.

Method: Again I used a Yaesu FT-817 and an iMac running cocoaModem. This time I set the dial to LSB 1500 Hz above the expected frequency. I listened to WWV at 5000 kHz before the test to measure the error and again after the test to make sure the rig hadn't drifted.
Soapbox: The FMT is always fun. Since there is no need to transmit, anyone with a receiver can play the game. No license required!

Method: Flex F5K w/Efratom-Rubidium Standard. Calibrated receiver according to Flex notes using Phase display. Used Phase display, in DSB mode, to get frequency. When display stopped rotating, or almost steady, that was the frequency. I estimated the last digit based on display rotation between two 1 hz frequencies, where the rotation changed direction.
Soapbox: This is my first FMT! S9 noise on 80 meters kept me from copying the W6 stations. I wish that there was a way to tune the F5K in fractional HZ.

Method: HP3586B, HP3586C Selective Level Meters locked to Trimble GPS Disciplined Oscillator. The HP3586B’s audio output was connected to line in of sound card on computer running Spectrum Lab for spectral analysis. The HP3586C was connected to same computer via GPIB bus with measurements performed by program written using EZGPIB. Antenna was station Carolina Windom 80 Short at 60 feet.
Soapbox: This is my fourth try at the FMT. In the previous attempts I used only equipment that might be expected to be found in a typical ham shack – transceiver, computer, frequency counter (first try). In my last try (04/21/2010), I used Spectrum Lab for spectral analysis of the transceiver audio output. All things considered, it should be possible to measure the frequencies about as well as anyone can just using a reasonably stable transceiver (receiver) with a digital readout and spectral analysis with a program like Spectrum Lab. The key is constructing a calibration curve by calibrating the receiver against WWV at several frequencies (say, 2.5, 5.0, and 10 MHz) after a sufficient warm-up period and close to the time of the FMT. The reason I don’t think it’s possible to do much better is – Doppler shift, varying signal paths, and noise. The Doppler shift, in particular, will limit the precision to the order of 0.1 Hz for any significant distance from the transmitter. While you might try to minimize the effect of Doppler shift by taking a number of measurements over a period of time, there’s no guarantee that the mean Doppler shift over any given period of time will be close to zero. In any case, for this FMT, I went over to the dark side, and picked up an HP3586 on eBay (actually, two HP3586’s, a B and a C model, but that’s another story). I’ve had the Trimble GPS Disciplined Oscillator for a number of years. The 3586B’s audio output was analyzed by Spectrum Lab, and the 3586C was controlled by a GPIB control program that I wrote using Ulrich Bangert’s EZGPIB (actually, I stole most of the guts of the program from K8ZOA). The program causes the 3586 to make a number of frequency measurements, calculates the mean and standard deviation and writes the result with a time stamp to a file. I tried to program a basic “hunt” feature which could home in on the FMT signal and set the 3586 to its narrowest bandwidth of 20 Hz to get a nice clean measurement, but my first try was a little too basic, and the results were somewhat less than optimal. The hunt feature is necessary because, although the 3586’s frequency counter will select the highest amplitude signal in its passband, there’s no guarantee that the FMT signal is the highest amplitude signal. But it does have one characteristic that can be used to find it: it’s persistent, at least for the 2 minute key down period. By the way, Jack Smith, K8ZOA, has a wonderful exposition on using the HP 3586 for off-the-air frequency measurements on his web site. It turns out that trying to divide my attention between two instruments became somewhat confusing, so the results reported here are in somes cases from the spectral analysis, some cases from the 3586 GPIB frequency measurements, and some cases an average of the two. Average Signal levels: 40 m: W8KSE -64 dBm, W6OQI -80 dBm, WA6ZTY -78 dBm 80 m: K5CM -65 dBm, W8KSE -70 dBm All into 75 ohm load, assume S9 = 50 microvolts (50 ohm), you do the math! Ok, I'm curious, so I did the math: -64 dBm (75 ohm) approx. = 9 dB/S9 (50 ohm). So on average, W8KSE on 40 m was 9 dB over S9, W6OQI on 40 m was 16 dB less, or about S8, etc. These are just the average levels. Signal levels varied by 10 - 16 dB or 2 - 3 S units.

Method: For TX: 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 running 300 to 400 watts out. 80 meter dipole slopes down from a 140' tower. 40 meter dipole hangs between two 80' towers. For RX: A FT-1000D in AM mode, with a PTS-250 clocked by a Z3801, for low side injection. Spectrum Lab software.
Soapbox: All of the TX stations had good signals in Oklahoma. Doppler seemed worse than normal on the West coast stations. On the plus side, it appears everone likes the new format. 73, Connie

Method: I use a GPS referenced HP-3586B receiver and measure the I.F. error. I use a 1:1 Lissajou pattern with one side of my scope looking at the 15625 Hz I.F. error and the other side fed from a GPS referenced HP-3336A generator which I tune to try and get the Lissajou pattern to stand still. (My twiddling fingers are still sore!) I simultaneously have Spectrum Lab, which is calibrated to my computer, measuring the 15625 Hz I.F. For more details on my measurement methodology please see: http://www.k5cm.com/k6OQK%20FMT%20NEW.htm
Soapbox: What a wonderful display of Doppler shift gone amok, particularly on 40-Meters! All signals on both bands were strong. Marv W6OQI who is only about 8 airline miles from me was all over the place due to Doppler. I always enjoy a good FMT and this was certainly a good one. The format and timing of the stations was excellent. Thanks to everyone who made this possible. _Burt, K6OQK

Method: I used an Icom 706 with the display set for 1 Hz precision. The antenna was a long wire (about 90 feet) with an SGC-230 autotuner. I connected the fixed audio output of the transceiver to the line level input of the sound card on a Pentium 4 computer, and ran Digipan software. I constructed a calibration curve using WWV and the results of previous frequency measurement tests.
Soapbox: All signals on 40 meters were 599 with the exception of WA6ZTY, who was still a very respectable 559. The Doppler shift was very pronounced on 40 meters, and I tried to average the fractional Hz swings to the best of my ability. The Doppler shift on WA6ZTY was so random that it was impossible to average the swings. 80 meters was open and had a lot of activity before the test began. However, when I switched to 80 meters for the test, the band had closed and I heard no signals at all on 80. I really like this format. It was very much like "real world" conditions, and it was fun chasing the signals with each hand off! Many thanks to the four volunteer stations for conducting this frequency measuring test. It was fun as always, and I'm already looking forward to the next one.

Method: Completely homebrew station consisting of a vertically polarized balanced loop antenna working into a direct conversion receiver whose LO was phased locked to the incoming carrier. The receiver's LO was measured on a 10-digit frequency counter referenced to a WWVB disciplined frequency standard. (http://www.qsl.net/kd2bd/fmt-methodology.html)
Soapbox: Love the new format! The Kp Index was 4, and severe thunderstorms were 60 miles south of me during the FMT. On 80, K5CM had the strongest signal (with fades every 10 seconds), followed closely by W8KSE. W6OQI was weak and difficult to lock on to under the strong QRN. The least amount of FM was observed on W8KSE, who is closest to my QTH.

Method: HP8935 service monitor offset by a few hundred Hz in SSB decode mode, using the HP8935 audio frequency counter to measure the offset. Reference output from an HP5334B counter was used as the HP8935 reference input. HP5334 reference calibrated 2 yrs ago against GPS 1 pps output. Get frequency indpendent 0.2Hz offset when measuring WWV. The counter probably misses or overcounts with noise. Estimated accuracy, barring mistakes, is within 0.5 Hz.
Soapbox: Great fun. This is my first attempt at the FMT. Used a method for which I could implement and reduce the data in a few minutes. It doesn't work on weak signals, so only got the CA stations. Hopefully, I didnt' make a stupid mistake and report something hundreds of Hz off.

Method: Flex-1500 fed by OCF Dipole. Flex set for 0 Hz IF and 600 Hz pitch CWU mode. VFO/DDS offset corrections were made: -0.01 to -0.046 Hz. Ext. Ref. was 10 MHz LPRO Rb calibrated against TBolt GPSDO. 600 Hz frequency analyzed with Fldigi. Flex-1500’s CODEC A/D sample rate error measured with Rb referenced frequency counter and corrected by Fldigi. System accuracy verified against local AM HD radio station carrier to be <0.1 mHz. Graphing of Fldigi’s freqanalysis.csv data revealed ~0.5 Hz of doppler variations from all distant stations. Best guesses were based on any alignment at high end.
Soapbox: Flex-1500 and dipole provided strong signals for all stations / bands. This was my 2nd FMT with the Flex, and I have reverse-engineered its internal clocking scheme for the DDS and CODEC. Thus I have ‘calibrated’ out system errors to less than 5e-11. Doppler shifting is my next learning curve (if that’s possible).

Soapbox: Propagation seemed fairly stable this time and I didn't notice any peculiar frequency-amplitude relationships on the graphs I plot. As usual W6OQI signal was weak here on 80 m but readable. Thanks to everyone involved in making these transmissions and giving us this challenge!

Method: HP 8664A SigGen externally clocked by Home brew GPS disciplined oscillator, generating marker signal within a few hz of test signal. Transceiver used was Kenwood TS-480HX with high stability OCXO, captured audio with Spectrum Lab. Post analysis done with Spectrum Lab and Microsoft Excel.
Soapbox: Great FMT, as always. Had good strong signals (S9 or greater) from all stations on both bands here into Colorado. Doppler was quite rampant, especially on the W8KSE and W6OQI stations. I was very impressed at the coordination between all stations and the fact they all were dead on regarding the published timeline. It was a perfectly conducted FMT!

Method: Method/Equipment - Antenna is a 35 ft long wire; JRC NRD-545 DSP receiver with TCXO; Using onboard soundcard in my Dell Laptop running MixW software. Warm up system for 9 hours, calibrated against WWV and CHU frequency standards for the last three hours. Calibration: Run MixW in BPSK mode, with receiver in narrow CW (w/BFO set at 1000Hz). System calibration stabilized at 0.1Hz against WWV and CHU.
Soapbox: Soapbox: During Contest: I set the rcvr. to contest frequency, place the MixW flag on the observed CW audio tone line on the MixW waterfall display, and record on worksheet, the observed BFO audio tone readout from the window at the bottom of the MixW page; recording the reading every 15 sec. on a work sheet. Then compute arithmetic average of the observed BFO tone readings. Compute the contest frequency as follows: Formula: Actual Transmit Freq (Hz)= Dial Freq plus observed BFO tone average minus the correction. Example calculation for K5CM on 40 m : Actual = 7055,000 Hz + 510.9375 - 1000.1 = 7,054,510.9Hz Then add salt and pepper to taste. Note during this contest I was unable to confidently ID the 80M signal from W6OQI '73 de W4RYF

Set the Flex 1 KHz below FMT station freqs and read audio offset using Spectrum Lab software.
Soapbox: My first FMT. Enjoyed it... Band conditions were fair to good. Even though I practicted with WWV,it took me until the 3rd 40meter measurement to get my routine down. Can't wait for next time.

Method: HP Z3801B GPSDO feeds 10 MHz reference signal to HP 3586B selective level meter. I. F. from HP3586B is fed to computer running Spectrum Lab for determining the differnce between the theoretical I. F. and the actual I. F. of the signal being received. For transmitting the FMT, the equipment consists of the same HP Z3801B feeding a 10 MHz reference signal to a HP 3336B signal generator. The HP3336B signal generator is set to the FMT frequency to be transmitted. The output of the HP 3336B feeds into the external VFO input of a 58 year old Johnson Viking One transmitter. The 100 Watt output of the viking transmitter passes through a 6dB pad to reduce the power to about 30 Watts to drive an Icom 4KL amplifier to about 500 Watts. This output power is fed to either an 80 meter or a 40 meter inverted Vee antenna. The Viking One transmitter is keyed for the CW portion of the FMT.
Soapbox: All received FMT signals were good in Southern California, except for the Doppler shift of course. I am sorry I lost the K5CM 40 meter signal measurement. I measured it but due to getting busy with the last minute FMT frequency change, due to QRM, I neglected to log the frequency reading on the HP 3586B level meter. It was fun receiving and sending the FMT and I look forward to doing so again in the future.

Soapbox: First use of fldigi in an FMT, having always used Argo previously. Learned that Argo allows ionospheric Doppler to be averaged more easily than fldigi, the carrier tracking loop time constant in the latter being too short.

Soapbox: This was my second FMT. I had high wind, hard rain and a GPS failure I didn't notice until after the FMT. Other than that it was fun!

Method: Flex 5000a, Rubidium standard, fldigi version 3.20.28 Use Fldigi in frequency analysis mode. Average 1 minute of key down (about 960 measurements)
Soapbox: Signals much louder this time than the November test with W8KSE on 80 meters being the weakest but still very copyable. I like the new format, less goofing around and waiting. My hat is off to the guys for a very well run FMT.

Method: Equipment: Yaesu FT-1000MP Mark V Field, Dell Inspiron laptop with Crystal WDM Audio. Method: K1JT "FMT" software (TNX, Joe!).
Soapbox: Signals were quite good at this QTH; on 40 meters, K5CM S8, W8KSE S6, W6OQI S9, WA6ZTY S9+5dB. Operator error on getting the 40 meter frequency for W8KSE ;-). On 80 m, K5CM S9, W8KSE S7, W6OQI S9+5dB. TNX to all 4 stations for providing this opportunity!

Soapbox: K5CM had what appeared to be huge Doppler on 40. Best I could do was take an average. W8KSE had a standard deviation of .5Hz with Doppler. 80 was tough, K5CM was in the noise and I couldn't hear w6oqi. Wow do I have a lot to learn about this. All the accuracy in the world is no good unless you can understand the Doppler
