VE3OAT ON 14055371.505 -0.025 1.78E-09 Martin says, Thanks very much for running your Sudden FMTs.I have an old Sulzer 2.5A frequency standard which this morning was above UTC by 2.5 parts in 10 to the 9th.  Good enough for this first attempt It drives a 1 kHz decade divider and harmonic generator. I measure the difference to the unknown signal using Argo software.

Used both SpecLab and  the counter to collect data. The "wildest" looking doppler variation appeared to be on the 40 meter signal
AC8Y VA 14055371.606 0.076 5.41E-09 Thanks for running the FMT.  I received your email about 3 hours before the start of the test.  Couldn't get everything set up in time and had to write the counter readings by hand rather than having the computer log them.  Anyway, here are my measurements and averages
VE2IQ ON 14055371.610 0.080 5.69E-09 Results from one day to the next were reasonably close. As with yesterday, I did not hear you at all on 80 M. The 15M band was quite dead here at 1:35pm EDT

K6OQK CA 14055371.350 -0.180 1.28E-08 This is my first attempt at using Spectrum Lab's program for a FMT.  Doppler spread was about 0.4 Hz wide on the 20 and 10 Meter bands.  I thought I heard the CW at the beginning of the 40 -Meter run but then it disappeared into the noise.  Nothing detected on 80-Meters.

Below are the comments from Brad, WB9FIP. Brad entered the Limited class, but I also entered his readings in the Standard class because he made the Honor Roll. (Limited rules allowed any means available to calibrate the radio before the FMT started, but know test equipment or PC's after the FMT started.)

Rather than drag out all the fancy equipment, this submission is for the LIMITED class. Here is what I did. Using a borrowed IC-706MKIIG (getting it ready for Field Day) I let it warm up for four hours, which is a time previously determined to achieve good stability. A half hour prior to the test, receiving WWV on 15 MHz LSB, computer software determined the radio dial error to be +28.55 Hz. From here on no computers, just the calibrated radio, a 440 Hz tuning fork (previously calibrated), and a stop watch. I hope the tuning fork and stop watch do not violate the "no test equipment" rule. All bands were tuned in the LSB mode to keep the math the same. After finding Connie's signal, I quickly tuned the radio for an approximate 440 Hz note (I have pretty good pitch), or you could find zero beat and then tune up 440 Hz on the dial. Tuning a little lower than 440 Hz is desirable to begin the next step. Now with your ear facing the radio speaker and an eye on the radio dial, strike the tuning fork, placing it near the speaker so that you can here a beat note between the two. Tune the radio higher in frequency so as to minimize the beat frequency. This assumes a radio like the IC-706 that tunes in 1 Hz increments. Now tune lower one, or at most two Hz to increase the beat frequency to a rate that can be counted. Use the stop watch to measure the time elapsed in ten beat cycles. Ten (beats) divided by the stop watch time (seconds) gives frequency in Hz to be added to the (corrected) dial readout. This should be good to about 0.2 Hz or better. Finally subtract off the 440 Hz tuning fork frequency (LSB) to give the measured carrier frequency. I hope this is right, or my measurements are going to be way off. If so, ignore the above wasted bandwidth!

Of course this is viable only if you can hear the signal well above the noise. Try as I might, I could not detect the 80 meter signal at all.

73 - Brad WB9FIP

 

I know there was some confusion about the two runs so I allowed anyone that asked, to submit readings on both days. I also allowed SDR's to enter the Limited class.

W1AW may have had daytime  FMT's in the past, but If so they were before the time that I used to participate  in the 70ies and 80ies. So this may have been the first.

Conditions seemed to be fair considering we are at the bottom of the SS cycle. My 15 meter signal was copied by a few, but know one got a reading on the 10 meter signal. I had hoped the 80 meter signal might be copied on either coast, but I now think we are just to far into the Spring/Summer season for this to happen, at least at my 300 watt power level.

There were some impressive readings with Jeff, (W3JW) making four band HR. Great readings Jeff!!!   Mike (AC8Y), and Bill (VE2IQ) read all three of the bands they entered to HR status.

 

Honor Roll: (.1 Hz or better on two bands or more)

W3JW*,  AC8Y**,  VE2IQ**,  VE3OAT, WB9FIP,  K8JQ 

 *  (Four Bands)

** (Three Bands)

 

Transmitting equipment used for this FMT:

A HP-Z3801 GPS clocks a HP-3336B. A small 10 db transistor amp follows and drives a 12BY7 / pair 6146 in a TS-830, which drives a Drake L4B to 300 watts output. 

Antennas:

80 -  Cage Dipole (favors East, West, and North)

40 - Dipole (favors East, West)

30 -  Dipole

20,15,10  - Pair of tribanders, one pointed East, the other North West. Power is split between the two.

 

 

Thanks to all that participated.
