Method: HP Z3805A 10MHz GPSDO, Marconi 2019 HF synth, HP 3325A LF synth, HP 54601A o'scope, FT-847 in AM/narrow mode, 5BTV and 80M/40M dipole antennas, Vista laptop running SpecLab, DigiPan for spotting, EZGPIB controlling Prologix USB-GPIB to set up and interrogate instruments, GPSCon for monitoring Z3805A; the 2019 was set to inject a reference beat signal to produce a ~400Hz beat tone, and the 3325A was tuned for minimum phase slip between it and the beat tone. Each run was recorded to a .wav file through SpecLab, and at a later time replayed to export data to spreadsheet to refine submission numbers. This time I also ran Fldigi concurrently in analysis mode for additional spreadsheet data.
Soapbox: 40M/80M good copy, 160M weak but readable. Thanks Connie for running the test. 73, L

Method: I used Open HPSDR (Mercury), Flex-Radio's PowerSDR, Trimble 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 file back in PowerSDR and ran Spectrum Lab, noting the offset from the HPSDR frequency. I used a TAPR TADD-2 connected to the GPSDO and receiver as a marker generator to check for DDS tuning word and sound card errors. Antenna: ground-mounted vertical 10 meters high.
Soapbox: EN82sx Signal levels in dBm, all measured on the same vertical antenna: 40 meter -20 Noise Floor -70, 80 meter -20 Noise Floor -60, 160 meter -40 Noise Floor -70.

Method: W5GI dipole to IC-7000; SignaLink interface to laptop running Spectrum Lab. After key down period, switched radio input to HP 3335A frequency synthesizer output (through 100 dB of attenuation). Thunderbolt GPSDO 10 MHz was fed into external ref. input of 3335A. Tuned synthesizer to match appearance of key-down signal on Spectrum Lab waterfall.
Soapbox: Good signals on 40m & 80m, but very disappointing that no signal was seen/heard on 160m. Setup can easily detect a -135 dBm signal at the radio input, but nothing was seen on the Spectrum Lab waterfall when listening on 160m for the FMT signal. May have to consider putting up a 'real' 160m antenna.

Soapbox: Good signals on all bands, after finding the 160m signal dodging the JT65 action. Very interesting frequency spreading observed on 80m, with several distinct frequencies seen. Which, if any, are right is the big question. My GPSDO lost sync and went into holdover about 2 hours before the test. I did a quick check against CHU and didn't seem to bee off by much, if any.

Method: Tuned a local oscillator to W1AW/5 frequency by ear and measured with a Heath counter IM-4100 that was clocked with an HP-10544A OCXC tuned to WWV earlier in the day at noon local time. The 40 and 80 receiver was an Atlas 210X and the 160 receiver was a Hallicrafters R-274D/FRR also known as SX-73, old and very heavy.
Soapbox: The 40 Meter signal was less than S1 down in the noise in Northeast Kansas, hardly readable with some QSB. I could not get my local oscillator level low enought for an easy measurement by ear. However, both signals on 80 and 160 Meters were better than 60 dB over S-9, very strong, with little doppler. 160 had slow QSB, a bit more than 80. I want to thank Connie, K5CM, for transmitting this FMT and everyone that supported this fun exercise.

Soapbox: Good signals on 40 and 80, but nothing audible on 160 m. Strong JT65 signals on the 160 m frequency did not help. (For what it's worth, I have included for 160 m the measured frequency of a weak carrier that was not audible but was found by the "fmtest" software.)

Method: Homebrew receiver with a rubidium reference into two PTS160 synthesizers. The first PTS if for local oscillator, the IF crystal filter is at 10MHz and the 10MHz reference provides BFO. The second PTS160 is set to 12MHz and is used to clock a USB audio adapter. Used FFT to analyze audio and then calculated result. Hope my math is right. Hi Hi.
Soapbox: Three of us participated in the measurement Don Dobson KK4OGX Hugh Gilbert Bill Fuqua WA4LAV Had a lot of Doppler shift on 40 and 80 meter bands so I expect substantial error there. I did average a set of FFT measurements to try to average out the error.

Method: FT-1000MP xcvr making alternating comparisons between the "unknown" frequency and WWV as my frequency standard.
Soapbox: Rapid flutter going into the noise level made the 40m measurement worthless (statistically unreliable at 10 hz). WWV (10 mhz) had begun fading with rapid flutter by the time of the 80m test. I switched to WWV at 5 mhz as a standard for the 160m run.

Method: Receive system. Antennas:160m vertical (almost). 80 meter dipole slopping down from a 80' tower. 40 meter dipole between two 80' towers, 4 element SteppIR in bi-direction mode for 20 meters. For RX I use an FT-1000D in AM mode with a PTS-250 for low side injection. Audio is feed to SpectrumLab. Other RX antennas include three 500' Beverage
Soapbox: Was fun to use W1AW/5 to transmit the FMT. Looking foward to another 100 years!!! For transmitting the FMT I use an HP-Z3801 GPS frequency source which clocks a HP-3336b and a PTS-250. This feeds a 10 db transistor amp which drives a 12by7 / pair of 6146. The final amp runs about 400 watts. There are no mixers or any device in the chain of amplifiers that might impact the accuracy of the GPS frequency source. I verify the accuracy of the TX system with a second GPS reference 73, Connie, K5CM aka W1AW/5

Method: My receiver is a GPS referenced HP-3586B Selective Level Meter. I sample the 15625 kHz I.F. and fed that to the vertical input of an oscilloscope scope and the horizontal side was is fed from a GPS referenced HP3335A signal generator tuned to 15625 kHz. During the FMT I tuned the receiver in 1 Hz tuning steps to produce as close to a 1:1 Lissajous pattern as I could. Once I got to the nearest 1 Hz of the FMT signal I tuned the HP3335A generator to make the Lissajous pattern as stationary as propagation would allow. This allowed me to add the I.F. error to the tuned-to frequency of the receiver and calculate the actual carrier frequency. You can read specifics about my methodology at: http://www.k5cm.com/k6oqk%20fmt%20new.htm Burt, K6OQK
Soapbox: Connie's 80 and 40-Meter signals appeared to be fairly stable, however, I could not hear his 160-Meter signal and I did tune down to the region where he was transmitting. My present aerial is a very low temporary dipole about 30' on a side. Thanks to Pam (N5KW), Connie's wife, for loaning Connie to us tonight. _Burt, K6OQK

Method involved phase locking the receiver's LO to the frequency of the unknown carrier minus a 1 kHz offset. The carrier's frequency was determined by measuring the frequency of the receiver's LO over a 10 second integration period while factoring in the 1 kHz offset, and taking an average of all the readings taken. Full details are available at: http://www.qsl.net/kd2bd/fmt-methodology.html
Soapbox: Connie's signals were very strong on 40 and 80, and strong and stable enough to acquire and maintain a solid carrier phase lock on 160 throughout the key down period. Many thanks to the ARRL and K5CM for the FMT!

Soapbox: My first FMT, 80M very strong, 40M good-QRM from a VE on 7057LSB, 160M heavy QRM from a digital signal, I think that I measured a carrier of another station that was tuning up. Found out afterwards that the Nexus 7 was not counting to the nearest .01 Hz like I had assumed. I will be using something different next time.

Method: I Calibrated my TS-950 with an accurate service monitor. I tuned the known frequency from the svc monitor in the CW mode, then measured the CW tone with an accurate frequency counter. Then I measured the tone frequency during the test with the counter and determined the difference with the known tone and the test tone frequency.
Soapbox: I had no propagation on 160 meters at all. I could hear the test on 40 meters but it was too noisy to accurately drive the counter. I had a way to do that with a weak signal, but could not get it set up in time.

Method: Homebrew GPSDO to generate accurate 10 MHz clock for Calibration, ICOM R75 receiver to generate baseband audio, and Spectrum Lab to record baseband frequency peaks, and using 6m-80m OCF Dipole. Record peaks for both 10 MHz Receiver Calibration before and after each Frequency Measurement, and for each Frequency of interest. Since R75 has a frequency error which is a linear function of the tuned frequency, the error can be computed for any tuned frequency. Receiver tuning error is computed, subtracted from the measurement, and the result is the true frequency measurement.
Soapbox: Although my antenna doesn't cover 160m, I thought I would get something on 160m, but I could detect nothing. I was wondering prior to the test, since so many like myself are space limited, and/or in antenna restricted communities, whether many would be able to get a good signal on 160m.

Method: Agilent 33522A Function Generator locked to PRS10 Rb reference oscillator injects RF sinewave over air to RX in AM mode to produce an AF heterodyne against signal of interest. Measured the frequency of the resulting audio beat note with FLDigi to nearest 0.1 Hz using its Frequency Analysis mode tracking filter. Accuracy depends only on the Rb oscillator and the A/D clock in the Icom 7600 receiver, more or less independent of the tuning of the RX with 10 kHz AM filter.
Soapbox: Booming S7 signal on 40m. Weaker, but still decent signal on 80m and 160m, but with lots of QRN on my end. QTH is 0.5 miles from AM B'cast station, the most powerful in the valley, and overload IMD obliterates all my receivers except for the trusty Icom 7600. My SDR's are all overloaded on those low bands, but I did use a Funcube Dongle for the 40m run, and recorded the RF session with HDSDR. Antenna was a Pixel Tech magnetic-loop antenna on a 6 ft mast in the back yard, and it worked like a champ for me on all bands. Pretty neat that I discovered some PSK and Olivia activity down around 1842 kHz while waiting for the FMT run there. Here I thought 160m was a dead band.

DDS frequency is set by Visual C program that reads the KX3 dial and sets each DDS. Audio frequencies measured with Spectrum Lab running on two computers with different setting. Results are combined based on measurement StdDev to give result. Used TCP/IP to control Spectrum Lab on the second computer. Spectrum Lab is a wonderful program.

Soapbox: 1st try with many "gotchas". I had grief with SpectrumLab - during the callup I had the spectrum width set to 10 Hz, then changed to 5 Hz at the beginning of key down and SL stopped displaying! The same thing happened for both 80 and 40 M, so I didn't get any data during key down. I realized (too late) that I should have had an audio oscillator at 800 Hz to a speaker so I could use beating to tune the FMT signal closer, allowing me to leave the spectrum width at 5 Hz. Obviously I have a lot to learn about SL! Thanks for the experience!!!

Method: I modified my ICOM 756 - to disable the internal reference oscillator and input an external reference signal GPS locked to 30MHz signal. When the external signal is attached it disables the 756 internal oscillator. The 30MHz signal comes from HP 8656B Signal Generator that has an external 10MHz time base provided by a Shera GPS locked 10Mhz (HP10811) Frequency Standard. All of this provides an accurate GPS locked 30 Mhz signal for the reference oscillator in the IOM 756. Spectrum Lab is used to read out the frequency along with the 1Hz readout on the 756 Antennas are a dipoles for 40 and one for 80, both about 50 feet up.
Soapbox: Absolutely NO SIGNAL on 160 meters in Oregon. The signals on 40 and 80 were solid S9. The frequencies were badly smeared by multipath on 40 to about 1 Hz on Spectrum Lab and not as bad on 80, about .6hz. Hard to figure where center was. A lot of guessing. I checked WWV before and after each measurement on 10MHz, 5mhz and 2.5 Mhz and they were real stable tonight. I Had Fun Jimmy W7CQ

Soapbox: In January 2013, FMT Group Member, Connie Marshall, (K5CM) proposed a "radio only" FMT exercise. Connie's edited post is shown here. Participants may use only a Radio Receiver or Transceiver. This means any external GPS or WWVB receiver can not be used as a reference for the Radio. NO external counters or computers. NO HP SLM's or other "non Ham radios" . Calibration from WWV or CHU is OK. Wall clocks with seconds hands are OK. Mechanical devices such as tuning forks are OK as long as they are not electrically driven. Connie Marshall, Jan 6, 2013 As far as I can tell no one, in the FMT group, has picked up Connie's challenge. The radio only methodology is not a trivial task and has been on my mind since Connie made the post. My current complement of radio hardware includes: Icom 706 MkIIG, Kenwood TS-570, and Yaesu FT-1000 MkV Field. Initially I was deterred by the fact that all three of these radios displayed frequency with a 10Hz minimum resolution. The "official ARRL" posted rules allow for a 10Hz margin of error. A participant can guess at the frequency and come in with a sub 10Hz error. My "radio only" solution would have to be within 0.5Hz resolution. While Connie's post was titled "Radio Only FMT" closer inspection of the post reveals serious additional restrictive requirements. If taken at face value many would be deterred by the requirements. I decided to take a stab at the challenge and deal with meeting the totality of the requirements at a later stage. For the moment I believe my implementation of "radio only" meets the spirit of the goal, meeting the letter of the challenge will have to come later. Ed WA6RZW, Elizabeth, CO

Method: I used my Flex Radio 5000A along with a HP 3336B signal generator both were locked to a GPS reference. Due to poor signals(poor antenna actually) I resorted to a simple zero beat method with the Flex in the AM mode and tuned the HP to zero beat using the Panascope display in the Flex. The scope display will show zero beat to less than 1 cycle/hertz depending on the signal quality. I was unable to detect a signal on 160 meters. I was hoping to use my active loop but was unable to complete the antenna prior to the event.

Soapbox: First FMT attempt, with a crude set up. Rig tunes in 10 Hz steps. Mentally averaged received peak frequencies shown on Spectrum Lab display and jotted notes. Added or subtracted that from rig's displayed frequency minus known offset error. Hopefully I'm in the ball park. Needed more time and patience to study Spectrum Lab software. Made no attempt at Doppler shift corrections. Guess I'll see in the results if I'm on the right track, or need to start over from scratch.
