Sorted by most accurate readings.



There was a contest on 160 meters so 80 meters was chosen for this FMT.  The accuracy of the first reading was widened to 500 millihertz to take most of the Doppler out of the equation and as in the last FMT, make the first reading more about speed than trying to figure out the Doppler.  Dick, K6BZZ (ex W5UFZ) sets at the top of the most accurate list, with Tom, W9TJ heading up the fastest reading within 500 millihertz for two FMT's in a row. Interestingly, Tom would have also won most accurate if he would have not turned in a second reading. Mike AA8K, although not within 500 millihertz, turned in the first report 11 seconds after the official start of the call up. He was about 3 Hz low.... not bad. 




w0cnn CO Blew the first entry big time- we will see how the later entry does.  Thanks Connie!
W2FD WPA Good Propagation Conditions for K5CM
WA1ABI RI Good signal tonight. Thanks Connie & 73.
K6APW/m OR Mobile in driveway. Not as easy!
K5BTK MS Much Fun! Thanks...
K6BZZ AZ Thanks for running the test Connie. Always a challenge. We have circular Doppler here in Arizona.
K6APW/m OR Tried this one mobile parked in driveway.



Rules used in this FMT:


This FMT will be focused at not only accuracy but speed as well.

You must submit your entry within 30 minutes after the start of the run. You can submit your entry as soon as you hear the first dit of the transmission if you want. Keep in mind that I may change frequency after I send QRL (is the frequency in use) if someone is using the frequency.


F1: A certificate will be given to the first station posting a reading within 500 millihertz.*


F2: A certificate will be given to the station posting a reading nearest the transmission frequency within the 30 minute reporting period.* 


Unlike the last FMT, you can try for both certificate's with two readings.  If only one entry is received you will automatically be entered in both events (F1 = F2). You can submit multiple times but your first entry will count as F1 and your last entry will count as F2. So if you make a mistake typing in your first reading (F1) and hit "submit" there is no way to correct it. A mistake on the second reading (F2) can be corrected by just sending another reading within the 30 minute period. Note that an entry without a frequency does not count as an entry. 



No West coast run this time.


*or a sticker if you received a certificate in a previous FMT



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 200 watts on 80m. 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.


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.
