WA4FJC VA FM08lf Imagination only on 20 M.  Nice sig on 40M & 80M
N2GL ORG cn85kp Tnx Connie, your effort is appreciated
VE3GSO ON EN92JX 20m just barely heard, 40m noisy, 80m strong and close to an USB conversation.  Fun!
W9ZB IN EM69xp 20M extremely weak here.  40 very strong.  80 strong, but with QSB.  TNX fer the practice, Connie!
W4JLE SC EM96 SWAG on 20 barely a signal, 40 and 80 good signals between digital and contester on 80 tks fer the test!.
W6OQI LAX
WA7KMR WWA cn87UU The 80 meter signal was very weak 40 and 20 were OK. RX is a Flex 5000a using a HP 3336B external reference. I used AM detection and zero beat with the HP 3336B. The 20 meter antenna was a Quad and on 40 and 80 on a un-tuned active loop antenna..
N3IZN SDG DM13ji Came in late, 20 meters measurment done on closing CW. Rig is Kenwood TS-50
KK4KAZ NFL EL88ql Nothing at all on 20m!
W2TX SFL EL97qw 20M: 0.2 uV on inv. vee.  40M: 300 uV on tuned 64 ft. Vertical.  80M; 300 uV on resonant 64 ft. Vertical.  Up to 0.3 Hz spread on the signals on 40 and 20. Rx is RF-590 locked to T-Bolt, timecard cal. against local GPS locked AM carrier.
N6RDR ORG DM13cx Wow! Great signal in southern California.  Even off the backside of the 20m antenna.  I used Joe Taylor's (K1JT) excellent Frequency Measuring Tools from his WSPR programs.  All measurements were with my old Icom IC-746PRO and a 20-meter dipole at 43 ft.
K7HIL AZ DM42ph Doppler pretty severe here, but fun to do it! Thanks Connie.
w9tj IL EM48wl Old man couldn"t get with it.  80 mtrs was only thing that came out of the slot  TNX Connie
K3KO NFL EM90 20M sig at noise level + had a birdie within a few Hz. Did not hear the first run on 20M. Other bands good signals
AB4RS VA FM18hw Tough conditions tonight. Could not hear 20m, but saw trace on the waterfall. 2 separate freqs actually, about 1 Hz apart. 40m and 80m were quite strong (both -70 dBm) but the energy was spread over about 1.75 Hz. I think I found a straight line.
W8NN MI EN82bk First time at this ... looking forward to FMT in April... Thanks... Bill
KB0EW MN EN34JL Thanks for the practice run.  This is my second try.
KA5QEP OK EM15mj Good propagation, heard all frequencies.  20 meter west was a bit better.  Thanks for the test.
AF9A IN EM69 Only able to copy a few CW characters on 20. Good signals on 40 and 80.  Tnx!
K1MC EMA FN42jk ICOM IC-7100 transceiver using the AUTO TUNE function 10 Hz display resolution
VE3OAT ON FN25eg Thanks for the practice, Connie.  Much needed here.  Measured your West beam at just 50 millihertz (mHz) lower than the East beam, but much weaker signal of course.  Lots of SSB QRM on 80m.  Thanks again!
W3JW VA FM17tn 20M signal very weak (no S-meter reading) but copiable, 40M signal S9+10db and 80M signal s9+5db. As usual, 40 and 80 sigs had lots of multipath and doppler shift. Tnx fer the "tune-up"----73
KM6QX EB CM87 Very strong signals, 40dB over noise floor on dipole for 20m & 40m.  33dB over on loop for 80m.
WAS2DVU SNJ FM29NC 20 M in the noise but could see scope trace and SL processsed it.  40 and 80 good copy. Thanks again Connie.
WA2DVU SNJ FM29NC 20 M was in the noise but could see trace and SL could process it!  40 and 80 fine.  Thanks again Connie.
VE2IQ ON FN15nt Dipole,  TS850 500-Hz CW mode, measure audio out.  20M-east: S1-S5 QSB, 20M-west: S0-S3.  West  measured 200 mHz higher than east.  Submitting west, seemed more stable. 40M: S9, 80M: S9+10dB. Tnx for the run.

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'

 

73,

Connie
