| AD8Y | OH | EN91fl | Forgot about this--chanced on the signal with a not-warmed-up transceiver. House temperature has been about 80F. Using a TS-450, calibrated against WWV, guesstimating nearest Hz error. |
| K0MZ | KS | EM28ix | Thanks Connie and Marvin for this fun FMT. 20 meter signal was S40+ with few fades to S7. Doppler +/- 1 Hz avg. Second signal was S-1 to S-2. 40 meter sig was S-20+ and 80 meter was 40 over S-9 both not much doppler but lots of QRN. Nice format for 20. |
| K0WM | CO | DM79jt | Really enjoy the test. No signal on 20 meters. Connie, thanks for your effort - Bruce |
| K1GGI | EMA | FN41 | Ok copy all around, thanks for the test. |
| K2LYV | WCF | EL88rb | |
| K3KO | NFL | EM90 | W6OQI in noise. Second run with turned beam not copied. |
| K4IVF | VA | EM96 | Had fits with everything....software to standards....mainly because I was foolish enough to upgrade many items since May. (for the FMT, upgrading the computer was a HUGE mistake, hence no 20m entry) Thanks to W3JW for helping with standards. |
| K5CM | OK | EM25 | Marvin was strong and easy to copy on the noon run. Doppler should be at a minimum with the sun almost at high-noon between us. It doesn't get much better than this. His frequency seemed to increase by about .2Hz on the North West run. |
| K5RKS | OK | EM15gj | Excellent run here. W6OQI was S4; K5CM 40m was S9; K5CM 80m was S9 + 20dB. Injected standard RF signal into ant term on receiver along with signal from antenna. Standard RF signal from HP3336B. HP3336B using GPS disciplined 10Mhz ext reference |
| K6APW | EB | CM87uv | S9 on 20M, S6 on 40M, S4 on 80M and quite noisy. Only hoping for +- 1 Hz. this FMT. Thanks for the efforts. |
| K6IQL | KS | EM28nr | Good fun as always. Tried a new sort scheme. TNX connie - john k6iql |
| K6OQK | LAX | DM04ud | I did not submit a reading for the 20-Meter FMT because I knew the actual frequency just after the 20-M FMT due to testing with Marv. I video'd my setup and method for all 4 runs and will post them on YouTube shortly after the results are up. |
| K9KK | OK | EM15 | Thanks Connie an Marv. Great to be back after a year long noise kept me grounded. All signals strong except for the 40M signal which was in the noise. |
| KA5QEP | OK | EM15mj | No signal heard on 20M. |
| KG6HSQ | SDG | DM13 | 20 M #1 did not copy call up did copy some key down, #2 Off back of beam + in dead zone, only copy back scatter 3.5 Hz wide WF. No guess |
| KM6QX | EB | CM87 | All strong signals near San Francisco. W6OQI 20m signal was a singler FFT bin with very small up-down drift. Unique in my experience. Maybe a NVIS like vertical Doppler at high-noon here. |
| N2GL | ORE | CN85kp | Nothing heard on 20M. Good signals on 40 and 80. Thanks for the practice. |
| N3CRT | NNJ | FN20 | Flex 3000 Thank you! Lots of fun. |
| N6SKM | EB | CM97 | Thanks for the FMT. Trying to find the most probable frequency is always fun! Tonight featured heavy fading with the apparent frequency varying +- 0.2 hz continually, with a secular drift upward during the test, maybe due to sunset here. |
| N8OB | OH | EN80 | A lot of storm noise in the area. Flex 6300 and Spectrum Lab. Fun as usual. |
| VE2IQ | ON | FN15nt | 20M dead here until W6OQI fired up. During east keydown a less stable carrier appeared some 3.5 Hz below. West freq approx 120 mHz lower here. Tnx |
| VE3GSO | ON | EN92ix | Lots of static, but good strong signals. Did not hear the 20m FMT as I was attending a funeral. Next time! Thanks Connie |
| VE3OAT | ON | FN25eg | Fair signal on 20 m but had finger trouble (argh!). Good sigs on 40 and 80 and hoping Dr. Doppler stayed home. |
| W2TX | SFL | EL97qw | RF-590 and USB soundcard, both locked to T-Bolt. Spectrum Lab SW. 20M dipole at 50 ft., and 64 ft. vertical on 40 and 80. 20M signal was barely audible. 40 and 80 were 100 mV, with deep fades. |
| W4VU | NC | FM06fb | First try; FT-450D, a guess really, better equipment failed prior to test. |
| W6BM | EB | CM87uv | Thanks for daylight 20 meters, S9 signal. 80 meters very weak |
| W6OQI | LAX | DM04vf | Strong signals on 80 and 40 in Southern California tonight. Great Doppler on 80. |
| W7PUA | ORE | CN84io | Thanks for the test! IC706 with GPS lock, Spec Lab software. Good signals on all bands. Even 80-mwas in the -110 dBm range. |
| W9GR | SV | CM99MG | Was too late tuning in on 20 meters. All I heard was "...W6OQI SK" - just the tail end! |
| W9TJ | IL | EM48 | Had a bad senior moment and did not get the 80 and 40 runs. |
| W9ZB | IN | EM69xp | 20M was S-7 w/QSB; 40M was S-9+30dB; 80M was S-9+30db w/QSB. All very nice! |
| WA2DVU | SNJ | FM29nc | Measufrements using SL were 42 mhz high on 80 and 59 mhz low on 40. Average of about 15 measurements per fx Will be interesting to see what method is closer - sl or the scope. 73, Bill. |
| WA4FJC | VA | FM08lf | TNX for the FMT Connie |
| WA9VNJ | WI | EN63af | 20m sig aimed east barely copyable, other 20m not heard. 80m fair, 40m better. Thanks for hosting the test. |
| WB0LXZ | KS | EM27pj | Thanks. All signals strong. I thought I was recording, but all three Spec. Lab files contained 0 bytes. -bill |

Transmitting equipment used by K5CM for this FMT:
A HP Z3801 GPS frequency source clocks a HP-3336B. The output is feed to a 10 db transistor amp which drives a 12BY7 / pair 6146. Then to a MLA-2500 running 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. As a reality check, I periodically log the frequency source against WWV and other GPS referenced sources. I monitor each transmission with a completely separate receive system to look for any instability or short term drift.
I typically see considerably less than 1 mHz difference at 10 Mhz when comparing two Z3801's or a Z3801 and a Thunderbolt, over a 10 to 10,000 second period.
Antennas:
160 - Vertical
80 - Cage dipole. (favors West, North, East)
40 - Standard Dipole hanging between two 80 foot towers. (favors East, West)
20 - 4el SteppIR at 70'
