| W3JW | VA | 3556233.790 | -0.068 | 1.91E-08 | Jeff says, The 80 and 40 meter signals were of good strength but the SL waterfall plot indicated "active" Doppler effects on both bands. It was not as severe as was noted last week. Got a beautiful set of data on 30 meters (with noticeably less Doppler effect than on 80 and 40 M) but I failed to record the transceiver dial frequency so could not translate the results up to the incoming RF frequency. I must have gone to sleep before the test was over! | |||

| KD2BD | NJ | 3556234.375 | 0.517 | 1.45E-07 | John says, I blew the 80-meter measurement and managed a first time 40-meter reading, but PLL loop filter issues (tightened up from last week to better handle QSB), severely damaged my results on both bands. Overall, signals on 80 appeared much stronger with less fading than on 40. In true Rube Goldberg fashion, I added a 16 MHz crystal oscillator, mixer, and amplifier to my receiver's L.O. to allow reception on 40-meters. My antenna was an amplified one-turn receiving loop antenna (13 feet of wire) that works remarkably well. A half-wave dipole was used on 80 as in previous runs.I am hopeful that Murphy won't strike "All of a Sudden" next time. ;-) | |||

Spectrum Lab, Screen capture by Burt, K6OQK of 30 meters (near the top of the water fall) .
15,625 is 10,115,398 Hz and 15,624 is 10,115,399 Hz. Since Burt is looking directly at the IF of his HP 3586B which is locked to GPS, he can read frequency directly with out the need of a reference marker and a difference calculation.
Conditions were noticeably better than last week with several stations achieving HR status. Doppler seemed very pronounced to the West on 80 meters with all the West coast reading the signal low. Mike, AC8Y, and Joe, K9HDE read all three bands to HR status. Jeff, W3JW has the most HR readings. Don, now has two weeks in a row of HR status, so it must have not been beginners luck last week hi hi. Phil, W1PW continues to demonstrate what can be done with simple equipment, using only a ICOM 756 Pro to read to HR status. John, KB2BD, got his home brew system running on 40 meters and made readings on two bands this week. Hank, WB0UIR made a good reading with his 65 tube National receiver .
Honor Roll: (.1 Hz or better on two bands or more)
Three bands - AC8Y, K9HDE
Two bands - W3JW, W1PW, Don (swl)
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. Then to a Drake L4B at 300 watts output except on 30 meters where the power is 75 watts.
Antennas:
80 - Cage Dipole (favors East, West, and North)
40 - Dipole (favors East, West)
30 - Dipole (favors East, North, West)
20, 17 - 4 element SteppIR in Bi Direction Mode (East/West)
Note: Because I put the results up quickly there will be mistakes, so don't hesitate to point them out quickly.
Thanks to all that participated.
