KMZ KS EM28ix 14121017 19:06:11 Thanks, Connie.  This is a different way to have fun with FMT.  20 meter signal was between S3 and S7 with some line noise.

W6OQI LAX DM04vf 7063994.4 19:35:35 On the 20 meter FMT I lost about 20 seconds because the 40 meter box was blank and the entry form requires a number in each box.  I quickly realized I had to put a zero in the 40 meter box and then I could make my submission for 20 meters.
AA0CL MO EM48 7063994.5 19:35:40 Booming signal on 40m in MO. 
KMZ KS EM28ix 7063995 19:35:53 Thanks again, Connie.  Lets see how 40 does after the short 20 meter run.  40 meter signals were very strong; about 40 over S9.  A little bit of QSB but mostly a very stable signal.  Lets do this again.  Thanks again.

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 300 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. 



160 - Vertical

 80 - New Sloping dipole. Sloping down from 140'. (favors West, North, East)

 40 - Standard Dipole hanging between two 80 foot towers. (favors East, West)

 20 - 4el SteppIR at 70'
