| Call | QTH | Area | Method/Soapbox | |||||||||||||||||
| AA5VU | TX | W5 |
| Method: Kenwood TS-570S and Fldigi Software in Frequency Analysis mode | ||||||||||||||||
| AA6LK | CA | W6 |
| Method: Used HP Z3801A to lock an HP5345A counter and Marconi 2019 sig gen; heterodyned received signal with (low side) sig gen in an FT-847 in AM and narrow mode; used the counter to measure audio when received signal was strong, and otherwise used laptop running Spectrum Lab to measure audio; compute received signal freq by hand. Soapbox: weak sigs all around, with the usual QSB, QRN, QRM. | ||||||||||||||||
| AA7OO | AZ | W7 |
| Method: Equipment setup: Rubidium 10Mhz standard used as external calibration into R2600 service monitor setup on 7099000hz bridged with antenna into IC-7000 set to USB 7096000hz with audio going into Dell D820 line-in running Spectrum Lab 2.74.11.
Method: SL recorded the audio while it did analysis with data output to text file which was imported to spreadsheet for post processing. Data collected was Time, peak frequency, peak amplitude, and noise_n.
Calculation: 1000hz standard used to calibrate sound card line-in with SL data points. correction factor determined and applied to the calibration beat offset, w1aw carrier, and wa6zty carrier. The difference from the cal beat freq and carriers were then subtracted from the calibrated 70799000hz signal. Soapbox: Enjoyed the FMT exercise and the challenges of setup and preparation. We had no problem receiving 40M from both east and west coast. We were unaware of the K5CM test. We were unable to do simultaneous w1aw 40M and 80M due to lack of calibrated equipment. Would make it easier if these were not simultaneous. | ||||||||||||||||
| AA8K | MI | W8 |
| Method: Standard Flex-Radio System SDR-1000 and Spectrum Lab Soapbox: W1AW: 80 meters okay, 40 meters, no signal, just noise. WA6ZTY 40 meters peaking at -82 dBm. K5CM 160 meters -87 dBm, 80 meters -62 dBm | ||||||||||||||||
| AB2WB | NY | W2 |
| Method: ICOM 706MKIIG with Hustler 6BTV antenna; Display calibrated using WWV; Rig on for 3 hours prior to test to stabilize; zero-beat test tone and adjusted for display error. Soapbox: Experienced a considerable amount of both noise and interference; had difficulty locating the test signal, especially on 40 meters (finally found it on 40 meters but did not have sufficient time to properly zero-beat with it). As always, I learned a lot in the process and would like to have the opportunity to do this more often. | ||||||||||||||||
| AB2WS | NY | W2 |
| Method: G5RV to an Icom IC-7000, with RigExpert SD PC interface, PC running Spectrogram 5.1.7 Soapbox: My first FMT, I enjoyed learning about WWV and using a spectrograph to help make measurements with my rig. Can't wait to see how I did! | ||||||||||||||||
| AB3HB | MD | W3 |
| Method: Kenwood TS-570S receiver with a calibrated LO was operated in LSB mode and the audio (difference) tone frequency was measured with a frequency counter. The reported value is just the (receiver LO frequency - audio tone frequency). The counter clock was locked to the GPS PPS "tick" with a 10 MHz disciplined oscillator. Soapbox: The 40M signal from W1AW was barely readable at this QTH and not sufficient for measurement. The 80M W1AW signal was generally S3-S4 but nearby RTTY signals made things difficult at best. Values read from the counter were "filtered" by eye and readings taken in the presence of the RTTY QRM were rejected. About 10 readings (with a 1 second gate period) were averaged. The standard deviation of these results suggests precision is no better than about 0.7 Hz for the W1AW result. On the other hand the signal from WA6ZTY was S5-S7 with no QRM and little QRN. The same procedure was used and the precision in this case was much better, about 0.2 Hz. Some Doppler flutter was noted on the W1AW signal but none was heard for WA6ZTY. | ||||||||||||||||
| AB4T | NC | W4 |
| Method: Elecraft K3 transceiver in USB mode, soundcard on computer's motherboard, and MixW 2.19 software. Warmed up all equipment for several hours. Calibrated setup with WWV on 10 mHz. Used MixW's AFC in BPSK31 mode to center and determine audio frequency. Added audio frequency to radio's dial frequency and applied calibration correction factor. Soapbox: Operator error changed K3's reference oscillator at some undetermined point in setup, calibration, or test process. Recheck of WWV calibration after test revealed new calibration factor and search for cause found reference oscillator frequency change. Results submitted used new calibration factor. It sounded like W1AW did not shift transmitter to 40m after 80m transmissions but continued on with signals at/near 80m frequency. No copy here on K5CM's 80m transmission. Thanks to all involved for conducting this test. | ||||||||||||||||
| AD7GH | UT | W7 |
| Method: Icom 756 Pro III, 40m Half Wave Dipole Inverted V. Toggling CW/CW-R listening for no audible frequency change. Soapbox: I learned a rule - practice before the test. The reason I didn't measure W1AW is because I wasted all of its transmission learning how to make a measurement. Next time I'd use a PC sound card to improve the accuracy of my audio measurements. | ||||||||||||||||
| AE5V | LA | W5 |
| Method: Kenwood TS-2000x / SignaLink USB / MixW / B&W Dipole / calibration with CHU and WWV on 3.3-10 mHz / Soapbox: Always enjoy the FMT. Tried a different method this year. Thanks. | ||||||||||||||||
| AF9A | IN | W9 |
| Method: Homebrew version of the SDR1000 receiver with ovenized reference osc. Soapbox: Couldn't hear W1AW on 40m. The other signals were pretty good. Thanks & 73 de AF9A | ||||||||||||||||
| K0MZ | KS | W0 |
| Method: Signals on 80 and 40 were received with Atlas 210X. 160 meter signal was received on Hallicrafters SX-73. Transfer oscillator was Drake TR-7 into a Heathkit IM-4100 counter clocked with HP 10544A crystal oven oscillator tuned to WWV. W1AW 80 meter sig was S+20 and 40 meter sig was S+10. WA6ZTY 40 meter sig was S-7 with QSB. K5CM 160 meter sig was S+60 and 80 meter sig was S+40. Great evening for a fun FMT. Thanks to all who provided signals. Soapbox: I tuned the transfer oscillator to the received signals strictly by ear. Using the Heathkit counter by itself makes the FMT very difficult to get any accuracy as its clock oscillator isn't very stable at all. But, clocking the counter with the HP 10544-A oven crystal oscillator makes the Heathkit counter extremely stable. This is what one might call the old fashioned low tech method of frequency measurement. | ||||||||||||||||
| K1EP | MA | W1 |
| Method: K3 plus Spectrum Laboratory Soapbox: very weak signal tonight from W1AM | ||||||||||||||||
| K1GGI | MA | W1 |
| Method: Heterodyne with oscillator referenced to gps, beat note recorded digitally, frequency measured with SpectrumLab.. Soapbox: Usable signals from all stations, k5cm on 80 was the strongest. | ||||||||||||||||
| K1UCY | MA | W1 |
| Method: WinRadio WR-G305E with AGC set to slow and AFC turned on. Soapbox: A local QRN source kept coming on making reception difficult. RTTY two nights before was much stronger. The 40 meter test bounced over my qth. | ||||||||||||||||
| K3JQ | MD | W3 |
| Method: ICOM 756 Pro III, RigExpert Plus computer interface, Spectrum Lab Spectral Analysis Software, Laptop Computer, and approximately 50 feet of 50 year old rubber and cloth insulated wire thrown out window and draped randomly over deck for an antenna.
Calibrated receiver against WWV at 2.5, 5, and 10 MHz. WWV's frequency was measured by tuning 1 and 2 kHz below (in USB mode) and above (in LSB mode) and measuring the beat frequency with Spectrum Lab. Calibration curve constructed by linear least squares fit to measured data. Note: the calibration "curve" for the 756ProIII approximates a straight line extremely well.
FMT transmission frequencies were measured in the same manner as the WWV frequencies, and calibration curve then applied to find the corrected frequencies. Soapbox: This is my second attempt at the FMT. In my first try last July, I simply hung a frequency counter across the 756Pro speaker terminals. Measurement method was essentially the same as above, but frequency counter limits precision to about 1 Hz given the conditions of the July FMT. Frequency counter also requires good s/n ratio. Spectral analysis should both improve the precision (although no attempt was made to calibrate the software for this test) and loosen s/n ratio requirements. My antenna system is currently being reconfigured, so that is the reason for the "50 feet of old wire thrown out the window" antenna. Although W1AW was coming in strong earlier in the evening, by FMT time, it had faded out completely. I was able to hear WA6ZTY on 40m and K5CM on 160m at test time. | ||||||||||||||||
| K4DXU | TN | W4 |
| Method: Elecraft K3 and PC based Spectrogram software to measure the offset frequency. I calibrated against WWV at 10 MHz after the test. Soapbox: It is interesting how difficult it is to measure a simple carrier on ham receiver. In sideband mode (which I used), you of course have to tune to an offset to get an output and then calculate the correction. My spectrum analyzer (HP 3585A) has a very long sweep time at high resolution bandwidths, so cannot be used directtly. | ||||||||||||||||
| K4GFG | FL | W4 |
| Method: Reference oscillator was 1 MHz ovenized quartz oscillator with homebrew divider/mixer to create adjustable RF combline spectrum. Reference oscillator was calibrated to GPS pps. Yaesu FT847 in USB mode used to capture both the FMT signals and the reference oscillator as audio tones, fed to computer to make WAV files. Homebrew DSP software extracted frequency of audio tones. Least squares linear curve fit to the phase walkup of the highest amplitude bin in sequential DFT's. Frequency of the tone is the slope of the curve. The difference between the two audio tone frequencies was applied to the known RF frequency of the reference oscillator to obtain the unknown FMT RF frequency. Soapbox: 80m signal from K5CM not heard. | ||||||||||||||||
| K4GK | GA | W4 |
| Method: Icom IC-746PRO Soapbox: Good conditions on 80 meters, with poor conditions on 40 meters and QRM here. | ||||||||||||||||
| K4KRW | NC | W4 |
| Method: Yaesu FT-897D. Homemade 80 meter Windom up 30 feet. Transceiver had been on for about 4 hours. I used the radio's CW-Tune indicator to zero beat against the signal. I tuned to either side of the signal and watched when the light transitioned between on and off. I picked the frequency in the center of that range. I checked transceiver frequency at 2.5 MHz, 5 MHz, and 10 MHz against WWV Carrier and WWV audio tones using PSK31 deluxe spectrum display. As best I could tell, it appeared that my display showed low by 3 Hz on 2.5MHz, 4Hz on 5 MHz and 5 Hz on 10 MHz. Since my measurements during the test were taken with only 10 Hz resolution. I didn't see any point in making any adjustments. Soapbox: I just happened across WA6ZTY while roving 40 meters (I love CW). So I quickly looked up the test on ARRL and got the 80 and 160 meter frequences. I caught K5CM on both of those bands. Signals for 40, 80 and 160 were all very good here. After getting my frequency measurements I read more about the test. I then went to WWV to check my frequency display on my 897. The tips in the QST article from 2002 were very helpful. I started up PSK31 Deluxe and set the waterfall to Spectrum mode. I narrowed the displayed frequencies to between 400Hz and 700Hz for checking against the WWV audio tones in SSB modes. I set the display to watch between 600Hz and 800Hz for checking against the WWV carrier in CW or CWR modes. It showed about 700Hz when I had a zero beat on WWV. I had used the radio's CW-Tune indicator when measuring the frequencies during the test, so I wanted to verify it's accuracy. This is the first time I have participated in this test. Next time, I'll have the spectrum scope available during the actual test. I'm sure my measurements would be more accurate. I guess I'll find out if I need to stay away from band edges. This was great fun. Thanks and 73, Richard K4KRW | ||||||||||||||||
| K4OL | GA | W4 |
| Method: Shift betewwn upper & lower sideband and look for a zerobeat. Split the difference between the two readings and add it to the lower frequency. Correct for 20 Hz error in dial reading against WWV. I can only read dial to 10 Hz Soapbox: Used a Yaesu FT 920 and a Verticle antenna, was not able to hear W1AW on 40 meters which is surprising since I almost always can in the evenings | ||||||||||||||||
| K4THE | VA | W4 |
| Method: Icom R-75 with 40m horizontal loop in attic and Spectrum Lab software. Switching between CW and Reverse-CW and tuning dial to minimize delta-f visually. Calibrated receiver against WWVB, WWV & CHU. Soapbox: S-7 to S-10 noise level. Could not hear W1AW or K5CM. I would like to have had more tone ON time. 20 second bursts not long enough. | ||||||||||||||||
| K5CM | OK | W5 |
| Method: FT-1000D, HP-3336b, PTS-250, HP-Z3801, Speclab Soapbox: The K index was 0. Does not get much better for an FMT. Signals were good form both W1AW and WA6ZTY. Thanks Joe and Mike. 73, Connie K5CM | ||||||||||||||||
| K5XL | TX | W5 |
| Method: FT-1000MP with TCXO calibrated to KRLD 1080 Dallas. Tuned (USB) for approx 500 hz tone fed to Spectrum Lab software. Added VFO freq to audio tone freq measured in SpecLab. Soapbox: This was my first try at FMT. The carriers sure were short! | ||||||||||||||||
| K6APW | CA | W6 |
| Method: Ten-Tec Argonaut V, calibration curve against WWV. Beat against digital audio generator through audio hybrid combiner. Calculate corrected frequency. Soapbox: Conditions quite poor. Thanks to Mike, Connie, and ARRL staff for runs. | ||||||||||||||||
| K6BZZ | AZ | W7 |
| Method: TS-50, HP-3336B, Trimble Thunderbolt GPSDO, Spectrum Lab
I measure the difference between the unknown signal and a known marker signal frequency generated by the HP-3336B. Attic antennas. Soapbox: No copy on W1AW on 80. Too weak to measure on 40 plus there was qrm on the signal. WA6ZTY very loud on 40, K5CM sigs weak on 160 and 80. I need better receiving antennas. | ||||||||||||||||
| K6HGF | CA | W6 |
| Method: HP 3586B, HP 3336B, Spectrum Lab | ||||||||||||||||
| K6OQK | CA | W6 |
| Method: For my receiver I used a GPS referenced HP-3586B with the 15625 Hz I.F. driving one side of an oscilloscope and the other side driven by a GPS referenced HP-3336B. The HP-3336B was adjusted for a stationary, or as close to stationary as propagation will allow, 1:1 Lissajou pattern. For a complete description of my FMT setup see: http://www.k5cm.com/k6OQK%20FMT%20NEW.htm. Soapbox: The W1AW signals were weak with a lot of Doppler on 40 Meters. The 80-Meter signal was better. The WA6ZTY signal was very good with some Doppler. The K5CM signals were excellent with very little Doppler on 80-Meters. K5CM's 160-Meter signal was 10 over S9 with very little Doppler. The FMT's are really appreciated. Thanks to all who make them possible. | ||||||||||||||||
| K7NUU | CA | W6 |
| Method: FT-817 and Ham Radio Deluxe Soapbox: Very weak signals tonight but fun exercise. | ||||||||||||||||
| K7TT | WA | W7 |
| Method: An ICOM IC-737 with homebrew Trap Dipole in Attic. PC running SpecLab and FLdigi. Entire system warmed up and stabilized for many days. Rig calibrations run with WWV at all close frequencies 2.5Mhz, 5Mhz, 10Mhz, etc. before and after the fmt runs. Offsets from calibrations are factored into the final number. Soapbox: No signals heard from W1AW or K5CM last evening, just noise. WA6ZTY was strong here. | ||||||||||||||||
| K8KO | TN | W4 |
| Method: Flex Radio 3000 Soapbox: First FMT in 35 years. Radios have really improved over that period. Very heavy QRM & QRN. Suggest less call up and longer carrier periods. | ||||||||||||||||
| K9JM | CA | W6 |
| Method: Secondary standard beat against off air signal Soapbox: If K5CM was on 80 meters, I never heard them. Everyone else had good signals. | ||||||||||||||||
| KA1BQP | RI | W1 |
| Method: IFR1500/S w Lucent RFG-M-RB Rubidium Standard. Spectrum Lab software Soapbox: I was not fast enough to catch the 40m W1AW run. Good signals on all the bands. Thanks to the gang at ARRL, Mike, & Connie. | ||||||||||||||||
| KB5ZO | MS | W5 |
| Method: FT950 receiver and computer running spectran.
Cal receiver on WWV 5/10/15 and offset spectran to 0 (700 hz beat note). Read frequencies and rechecked WWV at 10 (15 was gone). Drift of the receiver was about .5 HZ between first and last cal check. Soapbox: Signal on 40 from W1AW was not strong but readable. 80 was good all the way around. 40 for the west coast run was also good as well as 160. Thought I may have problems on 160 when a VE3 came on right below the frequency. WA6TZY seemed to be drifting up slightly but may have been my equipment drifting or propagation although I did not notice that on W1AW or K5CM | ||||||||||||||||
| KD2BD | NJ | W2 |
| Method: All homebrew equipment including a direct conversion receiver, WWVB referenced frequency standard, frequency counter, and H-field loop antennas. Method involved phase locking the receiver's LO such that an audio output of exactly 1000 Hz is produced when tuned to the unknown carrier. The frequency of the unknown carrier is then derived from a measurement of the receiver's LO. Full details are available at: http://www.qsl.net/kd2bd/fmt-methodology.html Soapbox: The Kp index was zero for the 24 hours leading into the FMT, resulting in stable signal propagation conditions. Reception of K5CM from 1196 miles on 80-meters was incredibly strong and stable. Reception of W1AW at a distance of only 129 miles, however, was surprisingly weak, and may have been received through backscatter propagation, yielding potentially poor frequency measurement accuracy. Hope to have even more homebrew FMT tools in operation for next year. Thanks to all who make these challenging exercises possible. | ||||||||||||||||
| KD5MMM | TX | W5 |
| Method: rig: Yaesu FT847, used Spectrum Lab to measure. Soapbox: Never heard W1AW on 80m, on 40m heard well enough to measure. WA6ZTY and K5CM were received here well. Hope I got close! 73 .. | ||||||||||||||||
| KE2N | VA | W4 |
| Method: Z3801 GPSDO, HPSDR Mercury, Spectrum Lab, ouiga board Soapbox: Worst signal I have ever heard out of W1AW. Other stations were fine. W1AW code practice the next night was S7-S9 on both bands. Murphy? | ||||||||||||||||
| KI8L | OH | W8 |
| Method: Yaesu FT-847, Calibrated to WWV. Switched between LSB and USB to zero beat and determined frequency. Soapbox: Really enjoy the FMT. Have learned a few new things about a radio that I have been using for years. Thanks Doyle..KI8L... | ||||||||||||||||
| KJ4LBZ | MA | W1 |
| Method: Yaesu FT-817ND with a MFJ-1622 apartment antenna for the receive at my remote QTH in Massachusetts. I first calibrated the Yaesu's digital frequency read-out using the zero-beat method on the WWV signal (the readout was correct, to its 10 Hz accuracy). Then I fed the audio from the transceiver into my Mac and used the BPSK-31 mode waterfall display in fldigi to lock onto the 1000 Hz tone in the CHU signal at 3330 kHz to test the rig's stability for a couple of hours prior to the FMT. I found the stability to be good to the stated 1 ppm accuracy (after warm-up) in the manual. I set my rig to USB and offset from the FMT approximate frequency by 500 Hz. Then I used the same waterfall display to visualize the unmodulated carrier of the FMT and locked onto the signal. The AFC function of the BPSK-31 mode allowed me to make several measurements of the audio frequency of the carrier. I then added the audio frequency back onto the display frequency to get my final frequency measurements for the FMT. | ||||||||||||||||
| KK8O | OH | W8 |
| Method: Kenwood TS-2000 using computer control on Ham Radio Delux software. Checking against the WWV 500 Hz tone using the Spectron software frequency readout. Soapbox: Could not hear any signal here except W1AW on 80 and WA6Zty on 40 | ||||||||||||||||
| KY5S | TX | W5 |
| Method: IC-7000 / IC-775DSP / Dipole
Switched between USB and LSB and adjusted dial to get the same tone as best I could by ear. Calculated the center of the two frequencies. Applied correction as to how far my receiver was off of WWV. Soapbox: I calibrate pressure / temperature automation equipment for a living so it is always fun to see how accurately I can measure something with the tools I have at hand. | ||||||||||||||||
| N0KC | KS | W0 |
| Method: Recovered GPS time base to Kenwood TS570S modified to accept external master oscillator input. Audio output to HP 5345A counter also using GPS time base in the external standard mode. In USB mode, receiver frequency setting is added to audio signal to establish transmitted frequency. | ||||||||||||||||
| N0NB | KS | W0 |
| Method: Fldigi in Freq Analysis mode reading display frequency from FT-920. Used generated CSV file to average error and then calculated resulting frequency. Since calibration against WWV and CHU showed rig reference oscillator to be low, the average PPM value was calculated against the measured frequency of each transmission to arrive at the final value. Soapbox: I tried tuning the rig so the carrier fell at 1000 Hz in the Fldigi waterfall by using the fine tuning (1 Hz) capability of the FT-920. Since this is a new method for me, it will be interesting to see if I got close at all. | ||||||||||||||||
| N0PFE | TX | W5 |
| Method: FT-990, Spectrum Lab V2.72, SoundBlaster sound card on AMD homebrew PC.
Prior to the FMT test I adjusted the FT990 LO against WWV on 5 MHz. The old rig had some corrosion buildup on the trimmer for the L.O. Soapbox: First time FMT participant. Strong 80 meter signals and marginal 40 meter with lots of QRN. | ||||||||||||||||
| N3DV | NJ | W2 |
| Method: Icom IC-7800 stock Transceiver, previously verified against WWV on 10,15 & 20 MHz; rocked the receive mode between CW & CW-R while tuning the frequency dial to zero beat the two tones (granted, I am tone-deaf and only got a 50% score on my Sonar test in Navy Boot Camp, when my ears were much younger). Soapbox: I would very much like to see this become a monthly event, again. I think it is a valuable "calibration" tool for the ears of the OOs, of whom I am one, who are out there helping keep us all within our allocated spectrum. Thanks for this run. Happy Veterans Day to you all up there in Newington. | ||||||||||||||||
| N3FG | PA | W3 |
| Method: IC-706 and Spectran Soapbox: Unfortunately, cndx were poor at this QTH. Only 80M W1AW sig was available. TNX for a fun event. | ||||||||||||||||

| N5DM | TX | W5 |
| Method: TS-480 & DigiPan v2.0 | ||||||||||||||||
| N5KAE | TX | W5 |
| Method: Drake TR-4 transceiver. Internal crystal calibrator was aligned with WWV 2 hours before. Internal calibrator used to align VFO knob skirt. Started on 80 meters, made the measurement twice. Switched to 40 meters, calibrated the dial once more, and made two measurements. Took digital pictures of the knob skirt and main VFO dial. Downloaded to my PC, then measured on the screen in millimeters to interpolate between dial skirt markings. I can send digital pics via email if you folks are interested. Soapbox: Using a 20-tube tranceiver for the FMT was fun! Oh how fast 5 minutes goes by when you are using vintage dials for measuring frequency the old fashioned way. I really enjoyed the chase, and hope I was reasonably close. | ||||||||||||||||
| N5LBZ | MS | W5 |
| Method: Harris RF-350K transciever calibrated against WWV on 5mhz. Soapbox: Good signals from all stations. Unable to participate on 160 as rig does not go that low and I do not have a 160m antenna. | ||||||||||||||||
| N5LUL | TX | W5 |
| |||||||||||||||||
| N5OHL | OK | W5 |
| Method: Icom IC-746Pro tranceiver I set my CW digital filter to a narrow 50 hz. Then I tuned up and down to "zero beat" for best signal by ear. | ||||||||||||||||
| N6SD | CA | W6 |
| Method: Elecraft K3 and HP 5316A counter Soapbox: I turned on the equipment on Saturday and let them stabilize till Wednesday. 15 minutes before the test I calibrated the K3's reference oscillator with 10MHz WWV. Due to the low signal levels I couldn't use the counter, too much noise. I used my ears to equalize the tone frequencys between normal offset and reverse offset in the CW mode. | ||||||||||||||||
| N6TP | CA | W6 |
| Method: FT-2000 Transceiver with audio to a PC Soundcard running Hamscope.
The calibration was done against WWV at 2.5, 5, 10 and 15 MHz Soapbox: All signals stood out clearly against the waterfall display. 73 Jim N6TP | ||||||||||||||||
| N7LRY | TX | W5 |
| Method: IC 7000, MFJ-1279 interface, Power Mac G5 Dual 2.3 GHz, FLDIGI software in frequency analysis mode. Measured WWV frequencies at 2.5 Soapbox: Measured WWV at 2.5 and 5 for error in system, calculated out error from measured signal. Signal reception was very weak, only S1 with system and occasionally the signal totally faded out. Hope conditions are better next year. This is my first attempt. 73's | ||||||||||||||||
| N8OB | OH | W8 |
| Method: TS-2000 and Spectrum Lab software Soapbox: Good sigs on 80 meters. Nothing heard on 40 meters. Copied K5CM on 160 and 80 meters. Lots of fun as usual. | ||||||||||||||||
| N8OQ | VA | W4 |
| Method: IC-706MKIIG + CR-262 + 55 foot per leg wire dipole
Standard WWV & CHU display error calibration. Soapbox: W1AW weak but measureable signals; WA6ZTY fair signals with some QSB,.abruptly off air 03:06 UTC (beam change?); K5CM nothing heard, both frequencies very noisy here. | ||||||||||||||||

| VE2DID | QC | VE |
| Method: Ft-902DM and HP 3325B. Zero beat the received frequency with the synthesized signal generator. Had the generator calibrated on the WWV and CHU signal. Soapbox: Signal was very weak on 80M and unusable on 40M. This is my first time and I would like to do this more often. | ||||||||||||||||
| VE6CB | AB | VE |
| Method: Yaesu FT-950 with HamRadioDeluxe software for 1 Hz readout. Left the transceicver on all day. Prior to the test I calibrated the FT-950 against WWV on 10 MHz. Adjusted the TCXO frequency for the slowest possible beat. Estimated within 0.2 Hz of WWV. Soapbox: I have never heard W1AW so weak. Not even moving the S meter with both pre-amps on, and selectivity down to 100 Hz. Very difficult to hear the beat due to background noise. Fortunately WA6ZTY was S9+, so had no problems. | ||||||||||||||||
| VE7BQO | BC | VE |
| Method: I adjusted the frequency of my Yaesu FT-817 to obtain a minimum change in pitch between CW and CWR settings of the transceiver. W1AW on 80 m and K5CM on 160 m were very difficult to hear and I couldn't hear them at all on their second frequencies. WA6ZTY had a good strong signal here in northern B.C., however, so I expect that my results for its frequency should be the best of my three measurements. Soapbox: Thank you for organizing this very worthwhile exercise. | ||||||||||||||||
| VE7TK | BC | VE |
| Method: I recently calibrated my Ten-Tec Orion against WWV and thought I'd give it a try. After 3 hours the rig was off about 1Hz. At zero beat the rig showed a corrected least significant digit (Hz) between 4 and 5. However, I thought it was closer to the 5. Hence my choice of 4.8Hz - hi! Soapbox: This was my 1st FMT but I hope to be back! | ||||||||||||||||
| W0CNN | CO | W0 |
| Method: Used my home-built W5GI Mystery antenna tonight. Utilized my home-built AVR powered GPS Disciplined Oscillator providing reference for a WB6DHW 995x DDS. Used this as reference marker and used OCXO equipped Kenwood TX-480HX to receive both FMT signal and marker. Fed via audio to computer with M-Audio Delta 44, captured audio with Spectrum Laboratory v2.7b20. Did post analysis with Spectrum Lab & MS Excel spreadsheet. Soapbox: All signals (W1AW, WA6ZTY, and K5CM) were strong and easy to copy into CO this evening. W1AW was peaking at S8 on 80M, S7 on 40M. WA6ZTY was peaking S8. K5CM peaking S9 on 160M, and 10+ over on 80M. Great FMT once again- although the transition from 80M to 40M during the W1AW portion is difficult to do so fast when one only has one transceiver & measuring gear to go with it. I much prefer the sequencing that Connie did between 160M and 80M- gives us just a bit more time to get set up on the second frequency. Thanks ARRL for sponsering another great FMT- always love this exercise! | ||||||||||||||||

| Method: IC756 pro Singer CSM1 with z3801 standard / compare audio tone of unknown to the tone of nearest 100 Hz standard frequency. Soapbox: Band conditions were so poor I actually went out side to see if my antenna was still up.W1AW was barely above the noise on 80 meters and not a trace on 40 meters. | ||||||||||||||||

Fldigi 3.13BB on Ubuntu 9.04
Measured TCXO error as -0.67 ppm by best fit analysis of measurement of WWV at 5, 10 and 15 MHz. Measured FMT signals using analysis mode in fldigi with correction factor based on TCXO ppm error. Soapbox: WWV 80 meters +20 dB s/n, 40 meters +2 dB s/n WA6ZTY 40 meters +15 dB s/n K5CM 160 meters +30 dB s/n, 80 meters +25 dB s/n s/n measured in a 200 Hz bandwidth centered on the desired signal. | ||||||||||||||||

| W2MJZ | NY | W2 |
| Method: A Z3801A GPS standard feeding an HP5087A distribution amp which in turn fed the external time bases of a Racal 6790 HF Receiver and an HP 3325A synthesizer. The audio output of the Racal (250 Hz filter with 700 Hz BFO) and the variable output of the HP3325A synthesizer were used to create a Lissajous figure on a Tektronix 2465A scope. Soapbox: Alas, the radio gods were not pleased with me at all this evening, and the normally strong 80 meter W1AW signal was down in the mud, and the K5CM signal on 160 was "slow fading" here in Yonkers, New York. The Lissajous figures on the scope were very noisy and unstable and I was unable get them frozen on the screen. | ||||||||||||||||
| W3JW | VA | W4 |
| Method: Icom 7800 locked to 10 MHz GPSDO into Spectrum Lab software Soapbox: All signals were measureable at this QTH. The W1AW 40 meter signal was skipping over me and very weak. The WA6ZTY 40 meter signal was very strong. Both signals from K5CM were loud and clear here. Plenty of doppler all around to make it interesting. Tnx to all for making this FMT possible. | ||||||||||||||||

Antennas: 160 mtr dipole, 80 mtr cage dipole, 40 mtr dipole
Used method for "radio only" from tips on the K5CM website: Determined correction factor from WWV 5.000 Mhz. Used that to calculcate variance from readout of what I heard. Soapbox: This was my second time to participate in FMT. I very much enjoyed working through this process, especially having a little bit of experience "under my belt." I sure would like to see this test happen more frequently, perhaps once per month... 73 Tim W4KP | ||||||||||||||||

| W4TVI | ID | W7 |
| Method: Frequency synthesizer phase locked to a GPS Disciplined oscillator with its frequency offset to give a beat note. Beat note frequency measured using Spectrum Lab application. Soapbox: It was great having WA6ZTY and K5CM as part of FMT. Their signals were good at my QTH. W1AW was very weak on 80M and unreadable on 40M. Thanks for another great FMT! | ||||||||||||||||
| W6BM | CA | W6 |
| Method: HP 5051 Cs beam disciplined oscillator driving pair of 5100 synthesizers. Hammarlund SP600-JX17 diversity receiver, 5100 HF+455 kHz to mixer, IF out into dual-trace scope, 455 kHz on other trace from other phase locked synthesizer. Fluke 207-5 WWVB tracking receiver as backup. Soapbox: W1AW: strong SSB interference on 80, nothing heard on 40. WA6ZTY: groundwave. K5CM: very weak on 160, nothing heard on 80. Generally poor and noisy band conditions. | ||||||||||||||||
| W6DMS | CA | W6 |
| Method: Kenwood TS-2000, CW decoderXP software Tuned 5 MHz WWV to 5000.00 khz and read freq of beat note with software (802 Hz). Tuned 40 meter fmt signal until same beat note frequency, read dial and interpolated. Havn't tried fmt before. | ||||||||||||||||
| W6OQI | CA | W6 |
| Method: HP Z3801 GPS receiver/disciplined 10 MHz oscillator as frequency reference for HP 3586B selective level meter as a FMT receiver. HP 3336B signal generator locked to the same 10 MHz GPS receiver. The HP 3336B drives one axis of an X-Y oscilloscope. Tbe I. F. output of the HP 3586B drives the other axis. The HP 3586B is tuned to the incomming FMT signal. Any tuning error is detected by tuning the HP 3336B for HP 3586B I.F. zero beat on the scope. A little math produces the amount of correction needed to the FMT signal frequency to take care of the tuning error. Soapbox: I was able to copy all signals. W1AW was weak on 80 and 40. WA6ZTY was S4 to S5 at my QTH near Los Angeles. The K5CM signal on 160 was the weakest of all the signals. The K5CM signal on 80 meters was S8 to S9 and the strongest of all the signals. | ||||||||||||||||
| W7GLF | WA | W7 |
| Method: IC-756PROII, Z3801A, PTS160, Spectran
I used PTS to generate a known carrier and measured a delta of 44.19 Hz on Spectran. It varied a tiny bit with propogation so this is my best guess. Soapbox: Could barely hear W1AW here near Seattle so kudos to WA6ZTY otherwise coming home from work early for this event would have been very frustrating. This is my first try so fingers crossed and lots of fun. | ||||||||||||||||
| W7ITM | AZ | W7 |
| Method: MARCA group effort at AA7OO. Motorola R2600 locked to PRFS-102 rubidium standard for reference tone at 7099 khz. 1000 hz divided from PRFS-102 recorded to calibrate laptop running Spectrum Lab. R2600 output mixed with received signal at ant input of receiver. Both signals recorded, measured difference and subtracted from 7099 khz. These results calculated by W7ITM. | ||||||||||||||||
| W7MOT | AZ | W7 |
| Method: Equipment setup: Rubidium 10Mhz standard used as external calibration into R2600 service monitor setup on 7099000hz bridged with antenna into IC-7000 set to USB 7096000hz with audio going into Dell D820 line-in running Spectrum Lab 2.74.11.
Method: SL recorded the audio while it did analysis with data output to text file which was imported to spreadsheet for post processing. Data collected was Time, peak frequency, peak amplitude, and noise_n.
Calculation: 1000hz standard used to calibrate sound card line-in with SL data points. correction factor determined and applied to the calibration beat offset, w1aw carrier, and wa6zty carrier. The difference from the cal beat freq and carriers were then subtracted from the calibrated 70799000hz signal. Soapbox: This is our club entry. There were 5 participants, aa7oo, w7itm, n0rmz, ki7tu, and k7ish. All participants took part in the setup and knob turning along with discussion of equipment and process being using. Several have never actually done an FMT and was a great experience for all. The process of averaging "Zero Beats" between 5 people is fun and why we have more elaborate methods these days. Each person is asked to process the data on their own and submit their findings. The club will submit an entry that is the average of everyone"s results, of course throwing out the out flyers. Norm Johnson, aa7oo | ||||||||||||||||
| W8TM | OH | W8 |
| Method: Elecraft K3 calibrated vs. 10 MHz WWV. Measurement by injecting sidetone monitor via "spot" and zero-beating. Soapbox: Surprised not to be able to hear K5CM on 80M. W1AW was quite weak on 40M. | ||||||||||||||||
| W9TJ | IL | W9 |
| Method: Icom IC-R75 with HB slave Rx. HP 105B with HB generator and DDS used to trigger Tek 465 scope. Soapbox: W1AW 80 mtrs S9+20, 40 mtrs I had to dig deep to get a few whisps of signal. WA6ZTY S9+20 some doppler. K5CM 160 mtrs S9 with some QRM, 80 mtrs S9+20 lots of doppler phase wander. | ||||||||||||||||
| W9ZB | IN | W9 |

| Method: HP 3586B with Trimble GPS reference. Nothing heard from W1AW on 40 meters. Pretty good sigs otherwise except for some fading. | ||||||||||||||||
| WA4OBJ | CA | W6 |
| Method: Kenwood TS-950SDX, Oscilloscope, RF signal generator, counter and audio generator all locked to a Z3801A GPS reference.
The rx was set to AM mode and the RF generator was set about 1 KHz low to generate an audio beat with W1AW. Adjusting the audio generator as a reference to make the beat tone from W1AW stand still on the scope, I measured the audio frequency and added it to the RF frequency. Soapbox: QRM was very high averaging about S8-S9. W1AW occasionally popped out of the noise by using averaging on the scope- at least long enough to make a measurement. Even with my California location only 70 miles away, I was unable to hear WA6ZTY well enough to make a measurement. Dave, WA4OBJ | ||||||||||||||||

displayed 3597113.90 subtracted 2.2769 (0.633 * 3.597)
final answer 3597111.62 Soapbox: Team effort with WA8OFU. Planned to measure on 40 M but heard nothing and switched to 80 M in time to make only one reading. Between us we have over 90 years licensed but our first FMT | ||||||||||||||||
| WB0LXZ | KS | W0 |

| WB3AKD | VA | W4 |
| Method: Zero beat against GPS referenced 3336b Frac-N synthesizer signal. Soapbox: Signals were not strong enough to use a phase comparison technique at this QTH, so zero beating was next quickest approach, but that has limited resolution. Quite a bit of static and a lot of RTTY QRM on W1AW's 80 meter frequency, and a VE3 dead on 1845. Note that I did hear all signals except K5CM on 80 Meters at my QTH. I got measurements from WA6ZTY on 40 and K5CM on 160 and, as always, enjoyed the challenge. Thanks for the effort everyone. | ||||||||||||||||
| WB5EXI | TX | W5 |
| Method: Icom IC-706MKIIG with extra fan for cooling/temperature stability SignaLink SL-1+ Radio-Computer Audio Interface Dell OptiPlex GX270 Pentium 4 CPU at 2.6GHZ with 3MB RAM W1HKJ's FLDIGI Hamware, version 3.11.6 in Analyze Mode Checked WWV before and after test at three frequencies; 2.5, 5, & 10 MHz to adjust for Radio Frequency and Computer Soundcard Errors | ||||||||||||||||
| WB5UAA | TX | W5 |
| Method: FLDIGI (version 3.11.6) frequency analysis mode running under Fedora 11 (Linux Kernel 2.6.30.9-96.fc11.i586) on a custom Intel Core 2 Duo 2.8 Ghz CPU. CPU has been on for months. IC-756OPro warmed up for about 13 hours. Antenna vertical Comet CHA-250 up 10 feet. Checked the offset of the sound card oscillator using the Digiscope display in WWV mode. It was pretty close as is. Then measured sound card error (MSI motherboard Realtek ALC888 audio chip set) by measuring 500/600 Hz tones frequency analysis mode from WWV 2.5, 5, 10, and 15 Mhz in AM mode. Haven't heard WWV on 20 Mhz in quite a while. Sound interface consistently reads 0.98 Hz high on both 500 and 600 Hz. Assuming 0.98 Hz high across the audio spectrum. Probably not a good assumption, but it's all I can do. Then measured IC-756Pro local oscillator frequency error by measuring 500/600 Hz tones in SSB mode. Created best fit y=mx+b line through those four averaged data points. Error (Hz) = (1.0266 * Freq (Mhz)) - 3.943. (Looks like the IC-756Pro should be pretty close to being on frequency around 3.840834 Mhz.) Interpolated error for FMT frequencies. Measured FMT and subtracted interpolated radio error and soundcard error for final result. Soapbox: Second FMT. First traditional FMT. I was surprisingly close last time with an IC-R8500 and an O'Scope. I'm thinking my $400 computer with a 24 Mhz sound interface bit clock is going to be more accurate than my $1200 Tektronix 100 Mhz O'Scope. Didn't hear or couldn't find K5CM on 80M. What was up with the fragmented tones towards the end of the ARRL transmissions? Sounded like something was broken. I'm anxious to see the results. | ||||||||||||||||
| WB6DCE | CA | W6 |
| Method: Icom R-75 receiver with long wire and dipole on 40 meters.. side tone offset set to 800 Hz.. so with an 800 Hz tone dial reads correct i used Spectran software to read the tone peak.. i used some averaging. i previously found error on on WWV 2.5, 5, 10 ,15 MHz and plotted a chart. which gave a correction for 7.1 MHz approx.. the tone wasn't exact so i had to correct for that.. my radio reads low 8.3 Hz at 5 MHz 11.06 Hz low at 10 MHz 14.43 low on 15 MHz some time back i tweaked the Icom as close as i could get with a rubidum standard i got. Soapbox: Never done this before, and I used to work in a Cal Lab several years ago! A bit of sweat as it was all over with in 15 minutes!! | ||||||||||||||||

| WM1L | MA | W1 |
| Method: Set-up included my Yaesu FT-950 interfaced with an RFSpace SDR-IQ run with SpectraVue software. I used WWV to calibrate the measurements, as best as I could. For this test I used the simple audio tuning technique, switching back and forth between USB and LSB CW settings on the receiver. Soapbox: This was the first FMT that I've tried. Propagation to my QTH was singularly horrible this night. Most nights of the year I can hear the regular W1AW code bulletin on 80m no problem, even if it is a weak signal. But this night, I heard absolutely nothing. Nothing certain from K5CM either. Even WWV was not cooperating fully. I heard an S1 signial from WA6ZTY, with QSB. I'll admit that it was kind of a fun exercise. We'll see how I fared. |
