Although I don't usually make note of speed in submitting results, it is interesting to see how fast some report results. K8JQ submitted 3 good readings 4 minutes after the end of the 160m run. N8OB submitted 3 good readings 9 minutes after the end of the 160m run.

| K8JQ | WV | X |
| N8OB | OH | I never saw so much freq movement on 40M as I did tonite. It scared me with trying to take a reading. Lots of fun as usual. |
| WA2DVU | SNJ | good signals to NJ - 160 was the weakest though - s2, others were s9 - 10/9. |
| WM5Z | NM | Receiver is an
FT-950AT stock. The software I used is FLDigi running in Frequency
Analysis mode. My antenna is a multi-element dipole. The signals were
very good from K5CM. Very strong on 40 meters equaling around S9 +20.
Nearly the same for 80 meters at S9 +10 and 160 meters was right at S9.
Nice job! hope everyone did well. This is my first FMT with this group.
Hey Steve, good to have you in the group, Connie
|
| W2FD | WPA | Did not hear W6OQI on 40 meters--W6OQI signal on 80 meters weak. Frequency measurements made to nearest Hz.using TS-450S only with TCXO,CW/Reverse CW, 1Hz. frequency step and 10 MHz. WWV for correction. Thanks for your efforts producing the FMT Test. |
| W5UFZ | AZ | No copy 160 meter sig; nothing heard from W6OQI on 40. W6OQI 80 meter sig very weak and changing freq +/- .25 Hz. Lots of something going on. Thanks for running the test. .7300 de Dick in AZ |
| WA1ABI | RI | Nil from Marvin tonight on 40m - that's a first. Not much QRN for mid-August. Thanks Connie and Marvin & 73. |
| K6HGF | LAX | Hope I did better than last time. Thanks for the FMT. |
| N7EP | WWA | Very noisy signals into Seattle tonight. No signal from WC-40M which surprised me as the propagation model looked good? I used a barrowed HP-Z3801 which sure beats a noisy WWV signal. Even with the Z3801 I think doing well in a FMT is more of an art than a science. Thanks for all the work you put into these tests Connie. They are great sport, Earl, N7EP |
| WA4FJC | VA | Could not hear anything on 160 M again this time. Signals on 40 and 80 were good with some slight fading here in VA. Used HP 3586B. Lots of fun. |
| W1PW | AZ | On 160 meters, some LID tried to jam the FMT signal but it didn't work. As usual, SL handled the QRM with no trouble. The WC 40 meter signal was not detectable in AZ, and the 80 meter WC signal had a tremendous amount of Doppler during the test. This was my first FMT using the Trimble Thunderbolt for frequency calibration. I hope it helped. Thanks Connie and Marvin for running these tests! |
| K5BTK | MS | The conditions were the poorest yet - never heard a trace from the west coast. A cockpit blunder limited me to the last 40 seconds of the test on 160m. Thanks for the fun! |
| VE2IQ | ON | Did not hear WC-40 |
| WB0LXZ | KS | My 3586 now has error CE-E, no AGC, but still usable. I could not find 40M FMT signals though I heard some other signals on the band. -bill |
| W6OQI | LAX | 40 meter signal was S8, 80 meter signal was S9 with a LOT of Doppler. 160 meter signal was S7 with minimal Doppler. Sorry my 55 year old Viking One intermediate power amplifier failed to work on 40 meters and I was not able to transmit the West Coast 40 meter FMT last night. |
| W9TJ | IL | Ionosphere was nervous. Only stability I saw was on 160. No West coast signals on 40. |
| K6APW/7 | OR | At local sunset only heard 15 seconds of 160M call up buried in noise. Heard nothing at all of WC 40M transmission. Both 80M measurement periods had very unstable path. |
| VE2AZX | QC | I am glad I could find you on 160m this time. Every new FMT allows me to refine my measurement method. Thanks for another interesting FMT. Jacques VE2AZX |
| W3JW | VA | Signals were moderate to strong and the band conditions were quiet (for Summer!). Plenty of doppler to cause discontent, particularly on 80 meters. I guess I will have to lend Marvin my Ranger II---it's only 46 years old and in the "prime of it's life"--- Hi. Thanks to you both for a great string of enjoyable FMT's. |
| KD2BD | NNJ | Many thanks for another FMT! Connie's signals were fairly weak on 80 and even weaker on 160. W6OQI's signals on 80 suffered some interference from a faulty street light. About 0.3 Hz peak-to-peak of Doppler shift was observed on all signals, with the sumbitted results being averages of all measurements made during the FMT period. |
| K1GGI | EMA | Nice sig on 160, S2-3, some qrm. Other sigs were spread over many hundred mHz. Thanks Connie and Marvin for all you do. |
| K5CM | OK | I heard Marvin briefly on 40 meters. Good signal on 80 meters. |
| N5LBZ | MS | inspite of an S9 noise level I was able to hear connie's signal on 40 and 80M. Unfortunately I am not at home and I was using a different radio than usual as a result the time of the 40M test was up b4 I could get a measurement. I did much better on 80M |
| K6OQK | LAX | Connie's 80 and 40-Meter signal were very good but had quite a bit of Doppler spread at my location - the signals had several steady locations. 160-Meters was weak but steady. I had some initial QRM from a W0 signal but was finally able to pin Connie's signal down and then go to the 20 Hz filter. I heard Marv tuning up on 40-Meters and then a second or so of the begining of his 40-Meter run and then he was gone. After a few minutes I called him on the phone to see what I was doing wrong. He was a bit frantic trying to figure out what had croaked in his Viking exciter. Thanks again to all for another great FMT and commeraderie. Burt, K6OQK |
| WB9FIP | WI | It would seem that I have offended the propagation gods. As I watched in dismay, the fickle ionosphere reeked havoc on Connie's first transmission, shifting it 200 millihertz lower over the first 90 seconds, and splitting into three distinct components. Then, both Connie's and Marvin's 80 meter runs might just as well have been spread spectrum signals for how they appeared on the waterfall. I decided to apply different statistical signal processing methods than traditional to derive my estimates. And, keeping my fingers crossed too. When I saw a few bits and pieces of Marvin's 40 meter transmission pop in and out, I thought a sacrifice to the propagation gods might be needed to restore harmony, but alas, as we have sadly learned, 'twas only Murphy at work. Hope the patient recovers soon Marvin! |

Transmitting equipment used by K5CM for this FMT:
A Trimble Thunderbolt GPS frequency source clocks a HP-3336B. A 10 db transistor amp follows and drives a 12BY7 / pair 6146. Then to the final amplifier, a Dentron 2500 running 400 watts on 160m, 225 watts on 80m, 200 watts on 40m. 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 WWVB. I monitor each transmission with a completely separate receive system to look for any instability or short term drift. The separate system is not locked to the GPS but calibrated by the GPS system before the FMT.
Antennas:
160 - Vertical
80 - Cage Dipole (favors East, West, and North)
40 - Dipole (favors East, West)
Current W6OQI FMT transmitting equipment:
My Transmitting setup consists of a HP Z3801 clocking a HP 3336B which drives a Johnson Viking I transmitter, the output of which is attenuated by a 6 db attenuator, to then drive an Icom PW-1 amplifier to about 500 watts. The antenna is an inverted Vee which favors north and south from the Los Angeles area.
Note: Because I put the results up quickly, there will be mistakes, so don't hesitate to point them out quickly.
