Method: Equipment: (1) Yaesu FT-767GX transceiver, (2) Timewave DSP-59+ audio filter, (3) Korg DTM-12 digital tuner. Method: (1) Connect audio out from transceiver through filter to the tuner input, (2) calibrate at WWV (2.5, 5.0, 10.0), (3) try to make 4 readings on each sideband, spaced 100 Hz apart, (4) crunch numbers & use averaged results.
Soapbox: I used a musical tuner to indicate the note and sharpness / flatness corresponding to each test. I then calculated the corresponding frequency. Calibration at WWV and all the number-crunching aftermath takes a LOT longer than the measurements. With this method, it's important to calibrate at multiple points and then use linear approximation to extrapolate the error for each measured frequency. This is my first attempt at anything like this, so we'll see. Oh, 40 meters was a real dog - could barely hear it.

Method: Using an HP Z3801A to discipline a HP 5345A counter and Marconi 2018 generator; generator signal heterodynes with measured signal in a Yaesu FT-847 in AM mode to produce audio; audio is measured by the counter; data collected by hand, averaged, and measured frequency computed.
Soapbox: The online data entry is a nice touch - I'll appreciate seeing the results much sooner. Thanks, L.

Method: I used only a standard Flex-Radio Systems SDR-1000 and Spectrum Lab audio software. The SDR-1000 does not have any special oscillator, just the stock one. I calibrated my SDR-1000 against WWV, then I set my receive frequency about 500 to 1000 Hz below the expected FMT frequency. I used Spectrum Lab to read the audio tone frequency and add that to the dial frequency on the SDR-1000.
Soapbox: The razor-sharp, adjustable filters on the SDR-1000 make it easy to pick out the desired signal. All were good, except W1AW on 40 meters. It only poked above the noise occasionally. This is fun stuff. I gotta get a good frequency standard!

Method: Yaesu FT-747GX Korg AT-12 chromatic tuner (converted to frequency) It measured the bfo frequency, using WWV and CHU as standards. With this info, I did a simple calculation to interpolate to the test frequency.
Soapbox: FMT is always fun for me. It's interesting to try various methods to make the measurement needed and, sometimes, I get pretty close, without having to use fancy stuff! Next time, I'll do better.

Soapbox: Had difficulty with considerable noise and interference (someone was transmitting an unmodulated carrier on about same 80 meter frequency on and off during test and was stronger at my location than the W1AW signal); I could not pick up anything on the 40 meter frequency (possibly my marginal antenna); great exercise, learned a lot, and hope to do better next year.

Method: Calibrated with WWV after Rig had been on for 3 hours. Readout on ICOM 756 is cycles, so I adjusted for phasing of my sidetone with the carrier and listened for them to "Lock" on, and counted how many times it drifted in and out of phase and compared up one cycle and down one cycle and interpolated (Guessed) at the fraction of a cycle. It was fun!! Thanks
Soapbox: I enjoyed it! Lots of fun! I got a certificate last year and I am proud of it!

Method: Beat Rx signal against HP8921 generator using K2 as mixer. Zero beat by ear. 8921 checked against WWV prior to test (looks like 8921 error was -0.3 ppm, results are corrected for this error). Measured no closer than 1 Hz, if that.

Method: Equipment: FT-847, microHam USB Digikeyer (using the outboard sound interface), HRD 3.5, DM 780 1.1, Spectran v2 (high resolution audio spectrum analyzer). Method: Determined the rig VFO calibration offset using Spectran to measure the difference between WWV tones and the rig VFO to a fraction of a Hz. Then I used linear interpolation using the 2.5 and 5.0 MHz WWV measurements to find the 80m FMT signal's offset. As a sanity check, I compared this result to DM-780's reported frequency of the FMT signal trace it's AFC attempted to align with it. The two agreed to less than one Hz.

Method: Receiver: Drake TR7, no external VFO HP 5335A frequency counter connected to Drake speaker out HP 8924C CDMA test set as signal generator Digital Camera Method: With frequency counter hooked to Drake's audio output, I measured audio frequency of beat tone between Drake's tuned frequency and FMT signal. When test ended, I disconnected the Drake from the antenna, connected it to signal generator, and measured again.
Soapbox: This was obviously far from the best of techniques, and a much better technique could have been used with this equipment, and a little more time to research the proper ways to make these measurements. But it was what I could cobble together in a very short time after a very frantic work week while watching our four kids while my wife is out of town. And even if it were not very precise, my method of measurement exposed the drifting that was going on in the Drake and test equipment - neat to see just how much that radio drifts. (I will need to look into this more to make sure it is indeed drift and not some other measurement artifact.) I used the camera to take photos of multiple frequency samples since I had no other recording mechanism and I knew I'd see a lot of drift between the Drake and the test equipment. The values were entered into Excel and averaged. A few hours after the test, I measured the signal generator against WWV and I think it is less than 1/2 hertz off. The counter received a 10 MHz clock from the signal generator. I had fun, and I hope I did the math right! Thanks for putting this on!

Soapbox: Test conducted by club members: Bill Luyster N4AMG Bill Fuqua WA4LAV and photos taken by Bill DeVore N4DIT. Had over S-9 120Hz noise from mercury arc city street lamps. Came on an hour or so before the test. Signals weak on all bands but ARGO seemed to dig them out of the noise. No signals were strong enough to move the S-meter. I now have a greater appreciation for propagation Doppler shift. Needless to say that stations near the transmitters that get ground wave have an advantage over those far enough away that they have to rely on sky wave propagation. 73 Bill WA4LAV

Method: I use a HP-3586B SLM as my receiver and a HP-3336B Precision Oscillator, both GPS referenced. I also use SpectrumLab, which is calibrated to my laptop computer. Because of errors in the tone output from the HP-3586B I sample and measure the 15,625 Hz I.F. I use a scope and Lissajou display with the HP-3336B for one input and the HP-3586B's I.F as the other input. This removes the need to calibrate around the 3586B's tone errors. I simultaneously use SpectrumLab to measure the resultant 3586B I.F. A complete description of my setup and methodology can be seen at: http://www.k5cm.com/k6OQK%20FMT%20NEW.htm - Burt, K6OQK

Method: Orion II (auxiliary receiver used), 80/40 dipole, Sabine MT9000 guitar tuner. I set the CW pitch to 440 hz (middle A) for the receiver. For calibration, I measured my receiver error on 2.5, 5 and 10 MHz using WWV. During the tests I zero beat the W1AW carrier using the spot function in the receiver and compared it with the Sabine for accuracy. I was able to resolve to 1 Hz and estimated rounding up or down based upon the WWV error.
Soapbox: Great way to learn more about my radio and it’s abilities. I look forward to increasing my accuracy next time.

Method: An indirect method was used: An HP-3801 GPS was used to lock a Schlumberger 4031 which was set to a known frequency near the W1AW/WA6ZTY frequency. The resulting audio was recorded and later, a differential frequency analysis was done using Spectran.
Soapbox: WA6ZTY's signal was extremely weak at this location: Because of a weak signal and some on-frequency QRM, it wasn't copiable at the time of the FMT, but it was visible in the post-analysis. W1AW-160 was weaker than last year, but both 80 and 40 were easily copiable.

Method: Icom 735 used as the receiver. Antenna was an Inverted V bent to fit the alloted space with an MFJ 949E tuner. PC with AMD K6-2 400 MHz processor running Win 2000, ESS sound card and homebrew computer/radio interface. I used the Argo program by I2PHD and IK2CZL to help zero beat with WWV at 10 MHz. I switched to CW mode and recorded the audio tone carrier offset as 777Hz. The IC735 should have offset of 800Hz. During the test I used the Argo program set the offset as close to 777Hz as possible. The IC735 tuning would not allow me to get closer than 8Hz. I then used Ward Silver's method of making a fine tuning scale to estimate the frequency. This was done eight times and the mean calculated to reduce the measurement error.
Soapbox: This is my second frequency measurement test. I have learned a lot from participating in the test and devising new methods to try and increase the accuracy. A huge plus for me is I have learned the limitations of my main rig (Icom 735). If I can just find a way to calibrate the RIT scale on the rig before the next test I think I can get even closer.

Method: Receiver used: Ten Tec Jupiter (Tuned to 1 HZ and 150 Hz CW Filter) Antenna use : Alpha Delta Communications Dipole Model DX-LB Up 40 Feet . I used the "SPOT" button on the TEN TEC Transceiver and with headphones on, Tuned the frequency while holding the spot button in on the Ten Tec Jupiter. The CW Tone was set for 500 HZ. I simply used my ear to match the tones! Here is how I calibrated my receiver against WWV: I tuned the 10 MHZ WWV signal on the Ten Tec Jupiter in the USB Mode and a second receiver an ICOM R-75 to the same WWV signal, but in AM mode. The tone on the Icom R-75 had to be accurate, since the AM mode uses no local oscillator, but the same tone heard in USB on the Jupiter changed pitch as I tuned the VFO. I adjusted the volume and put the speakers next to each other noticed that I could beat the two tones together very dramatically. With this method, the human ear and the human brain is the discriminating test instrument.
Soapbox: This is my very first FMT! It was fun and a real challenge for me as I am hearing impaired and wear two hearing aids.It was fun regardless of how far off I was! I chose a low frequency sidetone because i hear the lower frequencies as opppossed to the higher pitch frequencies! I chose 500 Hz! Tony KC8UR Mount Vernon, Ohio

Method: All homebrew equipment consisting of a WWVB-Disciplined Frequency Standard, a quadrature phasing direct conversion receiver, and frequency counter (with time gate referenced to WWVB) that measured the receiver's local oscillator. The receiver was tuned to produce a 1 kHz audio tone. The receiver's audio output was combined with a 1 kHz output from the frequency standard in a phase comparator with the resulting error voltage used to phase lock the receiver's L.O. to exactly 1 kHz below W1AW. The frequency counter read the receiver's L.O. (operating at 8x W1AW on 160 meters, and 4x W1AW on 80 meters), which were logged by computer and averaged to produce my final results. An air-core indoor receiving loop antenna was used for reception on 160, and an outdoor half-wave dipole was used on 80.
Soapbox: Thanks for another opportunity to give my homebrew FMT gear a workout. Signals on 160 were considerably more stable than on 80 where significant Doppler effects were evident throughout the test period.

Method: Equipment is a TS-2000, a laptop computer running FLdigi on Ubuntu version 7.10, and a Creative Labs 24-bit USB sound card. First I used FLdigi in the "WWV" mode to establish a calibration curve for the TS-2k. I measured the display error at 5, 10, 15, and 20 MHz using WWV, then extrapolated the curve back to zero MHz. I found that at a theoretical frequency of 0.0 MHz the display would read 2 Hz high, increasing by 1.6 Hz per MHz. Thus, for example, the readout is 2 + (1.6 * 20) = 34 Hz high at 20 MHz. Using this information I measured the W1AW FMT signal on 160, 80, and 40m using FLdigi. I added the FLdigi audio frequency measurement to the TS-2k's dial readout, then subtracted the CW sidetone offset and also the frequency-dependent offset from my measured calibration curve. This gave me the measured frequency to the nearest one Hz. Calibration was rechecked after the FMT using WWV on 5 and 10 MHz.

Measured at least three runs for each frequency and averaged them then subtracted the calculated frequency error.
Soapbox: After missing a couple of years of FMT, I decided to try it this year using W1HKJ's excellent Fldigi program which features a frequency analysis mode. By measuring the LO error against WWV and calculating the LO error at each FMT frequency, this year's FMT was a breeze. Well, it seemed like a breeze as I guess I'll find out how close I was!

Method: Using a Yaesu FT-847 with 1Hz tuning steps and 1Hz readout, and a 700Hz CW offset, I set the VFO to CHU Canada's carrier at 7.335MHz while in CW mode. The rig's internal 500Hz CW filter effectively removed the sidebands, which were weak anyway. I then measured the audio output of the carrier with a Fluke 179 handheld DMM. To measure ARRL's signals, I set the VFO to obtain the same audio output frequency as for CHU (bracketing between 1Hz steps, and interpolating). The accuracy of the DMM is about +/-0.8Hz (with precision 0.1Hz), while the accuracy of the VFO is unknown. If we assume that the accuracy of the VFO is the same at 7.335MHz, 7.045MHz, and 3.583MHz, what is then important is repeatability. Throughout the evening, I returned to CHU and found that it was always within +/-0.1Hz. My expectation is to measure ARRL's signals to within a few tenths of a Hertz. We'll see!

Method: Using SpectrumLab software to compare the unknown signal with the nearest 1 kHz harmonic from my calibrator. Calibrator signal is derived from an old Sulzer freq standard that I try to keep close to UTC by comparing it with WWVB 60 kHz using an equally old Fluke 207 VLF phase comparison receiver. Ancient equipment with modern software HI.
Soapbox: An interesting FMT this time. Lots of QSB, some QRM, and some pretty wild Doppler shifting and spreading at times. Not sure that my results are very consistent. The ionosphere is a Lady - always gentle but sometimes very difficult. Thanks for the test!

Method: I used my FT 817 and tuned it so that the signal produced the same pitch when the mode was switched between CW and CWR. Also, I recorded the indicated frequency in the USB mode and then retuned the receiver so as to get the same pitch in LSB mode. I added these frequencies and then divided by 2. Using these results I got 7.04530 for W1AW. I estimate my precision as + or - 10 Hz. Please note: I did not measure the 160 m or 80 m W1AW frequencies but had to enter some numbers in order to submit the form.
Soapbox: I found this test very interesting and, as a result, I have been thinking a great deal about the indicated frequency on my FT 817 and its relationship to the BFO and mode. I tried measuring the WA6ZTY frequency but by the time I had figured out what I should be doing the test was over so I am not very confident about this result. Thank you to all those who went to the trouble of providing this very worthwhile exercise.

Method: Everything used for my first FMT was home-made, other than the tranceiver! Home-built GPS Disciplined Oscillator using Brooks Shera design but my own designed Atmel AVR firmware with custom PID controller. The reference from this oscillator feeds my home-built DDS Oscillator/SignalGen/QSD receiver based on Analog AD9954 DDS. Used DDS to produce accurate reference signal, and fed its signal to 2nd HF Antenna. Used TS-480HX with TCXO in USB mode to tune and receive both FMT signal and Reference signal (Put Reference about 5-9 Hz higher than FMT signal). TS-480HX is connected direct to PC via M-Audio Delta 44 soundcard. Captured signals with SpectrumLab software, and calculated difference between Reference signal and FMT signal, added this difference to set frequency of DDS.
Soapbox: I preferred the format of the West Coast test on 40M- it utilized longer ID sequences (about 1 minute) between the three carriers, giving me better time to prepare/adjust my equipment for the 'middle' of the three carriers. Regarding the main 3-band test, switching between each of the three bands was also very challenging- I really had to scramble to prepare for each of the three tests! A bit more ID time between each of the three bands would have been nice. Either way, I got through it, and felt it a great sense of accomplishment to capture and accurately measure the three different bands. Thanks for sponsering this measurement test- it was great fun to figure out the best way to use my home-built equipment in such an exercise. Maybe next year it would be nice to measure and publish the results of your signals to .01 Hz- There are many folks who would prefer the higher resolution! -Reid Bishop- W0CNN

Soapbox: In the Phoenix, AZ area, WA6ZTY was never heard. The propagation must have been my enemy. I heard lots of East Coast stations, but nothing from the West Coast FMT station. On 160 meters, my measurements are probably as much 'imagination' as fact. I never found the W1AW call-up on 160 meters, but then heard an incredibly weak (RST 1-1-9) 'dead carrier' amidst the noise, shortly thereafter, which seemed to be 'in time' with the W1AW signals on other bands, so measured it. I'll keep my fingers crossed on this one.

Method: Frequency measurements are referenced to a GPS based frequency standard (Brooks Shera, QST July 1998). The 10MHz outpur of the frequency standard drives an HP3586C. The synthesized tracking generator outpur of the HP3586C feeds the input of an AM receiver tuned to the frequency being measured via an 10dB directional coupler and variable attenuator. The receiving antenna is connected to the AM receiver through the low loss path of the directional coupler. The HP3586C frequency is adjusted for a convenient beat note frequency (400~600Hz) and the attenuator is adjusted for maximum beat note amplitude. The beat note frequency is measured using DL4YHF's Specrtum Lab software. The measured frequency is then calculated using the beat note and HP3586C frequencies
Soapbox: W1AW signals on 40M and 80M were good (S5~6) this year. The WA6ZTY signal was excellent (S7). I like the test format and reporting method used this year. I greatly enjoyed the 2007 FMT and hope you continue to hold it each year.

Method: HP 3586C Frequency Selective Level Meter using built in tracking generator, Attenuator, and PC running Spectrum Lab FFT software. Method was to measure the difference between the carrier generated by the tracking generator BFO and the ARRL carrier. This difference is at audio and measured using the FFT software. The difference is added or subtracted from the displayed frequency on the HP3586C to come up with the ARRL carrier frequency. A second receiver (FT-100D) was used to monitor the ARRL 160 meter frequency through out the test so I could hear what band was being measured. Antenna: 40 meter dipole on the HP3586C and a 30 meter dipole on the FT100D.
Soapbox: I copied the west coast test and recorded the data. They had a weak but usable signal at my QTH. Unfortunately, stupid me, I failed to write down the base frequency that the HP3586C was tuned. I have the difference frequency but I don't have the base frequency to determine the final answer. Maybe I will be less stupid next year!

Method: W1AW = 1854.116420KHz IC-736 HF rig in CW mode to hear W1AW on 160m. Marconi 2022C signal generator being feed by HP-Z3801 GPS standard. Couple sig gen into receiver until very near by W1AW signal. Use Spectran on laptop PC to view audio passband of receiver. Measure audio difference on Spectran disply between W1AW carrier and signal generator carrier. With algebra, you now can find the carrier frequency of W1AW since the sig gen freq is known to better than 1E-10.
Soapbox: Only measured W1AW frequency on 160m. Nice strong signal, but moderate QSB as well as changes in frequency due to shifting propagation. Noticed spreading of carrier on wavefall display as well as .08Hz shifts in freq when spreading was at maximum. Had to take optically weighted average of displayed frequency to deduce the W1AW carrier frequency. Will have to try 80m next year.

Method: Equipment is an IC-7800 warmed up 4 hours, with a B&W folded dipole antenna. I switched between CW/CWR and listened for the pitch change. Afterward I rechecked the CW/CWR pitch change with WWV at 10mHz.
Soapbox: The FMT should be every 6 months, one summer, one winter. Its a challenge and lots of fun. When the bands open up, maybe a few higher frequencies could be added.

Soapbox: I finished making the West Coast transmission then decided to listen for W1AW. I was surprised to hear it so well and scrambled to set up a zero beat test. I expect to be within about 0.1 Hz but certainly no better than that. BTW, this online entry form has the West Coast callsign wrong, it is WA6ZTY, not WA6TZY. -Mike-

Method: Yaesu FT-857 with DL4YHF's Spectrum Lab (Audio Signal Analyser). Computer sound card errors were corrected using WWV 500 & 600 Hz tones with RX in AM mode. RX tuning errors were measured with same tones while RX was in USB mode. (RX error about 1/2 ppm.) Corrected measurements with proportional error for each frequency.
Soapbox: Good propagation to CA on 80m & 40m this year. Thought I had the 160m signal, although couldn't hear it. However, after the test ended, the signals were still there, so some other environmental junk.

Method: With a K2 in CW mode and 650 Hz sidetone offset, I tune the incoming signal sidetone to align in the center of the 650 Hz Marker displayed by the Spectrogram software. Then used a signal generator to visually match the signals in the spectrogram software and read the frequency on the signal generator.
Soapbox: First time trying the ARRL FMT. Could not copy the 80 meter signal because of the QRM was too strong. Good signal on both the 160 and 40 meter test. Decided to conduct the test at the last minute and did not have adequate time to validate my test measurement methods. Hopefully I am within 10 HZ.

Soapbox: I really did this just for fun and I'm sure I'm way off the mark. Just read the article today in QST and decided to try it about 20 mins before the test started. I wanted to use a freq counter on the audio out of the receiver to compare the zero beat, but, the lashup was at the last minute and didn't work so I used my ear.

Soapbox: 160 was by far the hardest to hear/see. Signal strength was at or below my noise level. Without the waterfall display I would never have been able to measure this signal. 40 meter band signal was the strongest signal at or around S9 (Calibrated at 100 uV). I could not even heat the Left Coast station. Maybe next year he could run multiple frequencies? Great program offered by ARRL staff. Should do this more often. Steve
