Most of the North American mainland was lightning-free but rain static was reported in British Columbia during the evening. The western Pacific was once again very active, with numerous lightning-rich storms covering central Japan and Indonesia into central and southeastern Australia. The central and northeastern coast of Australia was in the clear allowing a bit more activity there than in previous session. New Zealand also experienced some evening and overnight storms.
Geomagnetic conditions were very quiet through this session in spite of the Bz which has been pointing to the South. Solar wind velocities are averaging near 300 km/s. DST values have been very stable through this session at or exceeding the center line into positive territory. Unsettled conditions are possible in the coming days as a coronal hole will become geoeffective and an active filament could result in a coronal mass ejection. Stay tuned or check solarham for updates!
Evening propagation was outstanding in North America. As with other recent sessions, full darkness was necessary for stable conditions which meant that quality openings in the West were not realized until later in the evening. QSB was active but a number of near-detection-limit QSO’s were reported. Interesting late evening QSB was reported in the Pacific and West. Noise was low for most station although there were periods in the late evening when stations in the West reporting spiking noise levels and a number of rain static reports were received from British Columbia. This is what a good session can look like. In typical form, however, many of us are cynical and don’t expect the same good propagation to occur tonight for a number of reason detailed in the past. We will have to wait and see.

Ted, KC3OL, completed his first 630-meter QSO with NO3M using JT9. Ted is using about 20 watts from an MF Solutions transmit converter and an 80-meter dipole configured as a Marconi-T. Ted also completed confirmed JT9 QSO’s with (but not limited to) K5DNL, NC0B and KB5NJD. A screen capture of the Ted’s first QSO follows:
John, WA3ETD, had a very strong night, completing JT9 QSO’s with K9SLQ, KA1R, N1DAY, VE3CIQ, K5DNL, K9MRI, K9KFR and KB5NJD.
Clint, KA7OEI, also had a great session, completing QSO’s from Utah with W7IUV, VE7CNF, K5DNL and KB5NJD.
Keith, K0KE, completed a JT9 QSO with Ben, N1VF.
Rob, NC0B, reported JT9 QSO’s with K9KFR, KC3OL (16th state), and CF7MAY. He and I also completed a CW QSO. Rob offered the following details about his overnight activity via email:
“…VK4YB was copied calling CQ at 10:44Z at -27, 10:48Z at -26 & 10:50@ -25. Roger worked VK4AQJ between 10:52 and 10:58, but I never decoded VK4AQJ.
VK4YB called CQ later at 12:05Z @ -26, 12:07Z at -25, 12:09Z @ -24 & 12:11Z @ -25. That was the last decode.
I got up in the middle of the night and copied WB4JWM calling CQ over a 50 minute window. Don’t know if he only peaked up then, or whether his CQs were sporadic.
8:35Z -26, 8:37Z -27, then 9:01Z -25, 9:03Z -25, 9:03 -25 and then one more decode at 9:23 -27. Georgia would have been a new state for me. I called him 7 times starting at 9:38Z, but his signal had either faded out or he was no longer monitoring.“
Ken, K5DNL, completed JT9 QSO’s with WA3ETD, KC3OL, WB4JWM, KA7OEI, CF7MAY, VE7CNF, W0YSE and N9RU. Using WSPR overnight, Ken reported seventeen stations including VK4YB and received reports from 94 unique stations including ZL2AFP, YV7MAE, ZF1EJ and ten Canadian stations. Ken shared two-way WSPR reports with VE3CIQ and K9FD (/KH6).
Neil, W0YSE, reported a great session and offered the following extensive details:
“I worked Joe, NU6O on JT9. That took ~22 minutes to accomplish (Thanks, Joe, for hanging in there!!!). Then I worked KA7OEI (our first), then CF7MAY (another first) and then VE7CNF, all on JT9.
This morning I rolled over and looked at the clock at 3:50 AM PST, decided to go check the radio PC and found Ken, K5NDL calling CQ on JT9. After much QSB and several repeats we accomplished a QSO, another “first”. Ken varied from -27 to -22, while he was hearing me at zilch to -24.
WSPR was very good this session. I had 42 stations hearing my 1.5w EIRP, and these were the ones >3000 km:
…and I heard 10 stations including 1 decode of Roger, VK4YB at -30, and a boat load of Merv, K9FD (44 spots with a best of -9). I am thinking that Merv might have been able to hear my CW ID at times overnight.”
Al, K2BLA, had a good vantage point to observe the evening activity, reporting that he heard “…JT9 guys wkg 5 different stns that wud be new to me last nite. Cud not hear the new ones. Did manage to wk K9EGT for a new one. WSPR: hrd by 49 and hrd 18” Al also worked K9SLQ during the evening (second hand report).
Larry, W7IUV, completed JT9 QSO’s with KA7OEI and KB5NJD. Larry reported a number of other stations, including CF7MAY and K2BLA on the long, diagonal transcontinental path across the US. On CW, he reported W0RW during the mid-evening and made some interesting observations about my CW signal (KB5NJD) showing stability not seen in some time. Larry also reported W0RW as strong on CW at his QTH in the later evening. This morning, Larry received the VK4YB-side of a JT9 QSO with VK4AQJ, details follow:
“1052 -25 -0.2 1098 @ VK4AQJ VK4YB -26
1054 -22 -0.1 1098 @ VK4AQJ VK4YB RRR
1056 -24 -0.0 1099 @ TKS JIM 73″
Larry also noted a later CQ by Roger at 1209z at -25 dB S/N.
Joe, NU6O, completed a JT9 QSO with W0YSE. He also reported WSPR from VK4YB and received WSPR reports from ZL2AFP.
Toby, VE7CNF, reported that he had two JT9 decodes on his console this morning for VK4YB: 1044 -26 0.1 1098 @ CQ VK4YB QG62, 1046 -25 0.2 1098 @ CQ VK4YB QG62
Roger, VK4YB, reported that “QRN continues but KL7L managed to make it through for both ways WSPR reports. I worked Jim, VK4AQJ, for a first time JT9 QSO.“
It was a great session at KB5NJD. While I spent time calling CQ on CW early, the best results during this evening session were on JT9, as I completed QSO’s with N9EGT, W7IUV, WA3ETD, KA7OEI, K9SLQ, KC3OL and VE7SL. VE7SL was uncharacteristically strong but the path to the West and Northwest was very interesting later in the evening as QSB seemed to move my CW signal from North to South and back again between W7IUV, KR7O and K9FD. Uncharacteristically strong and stable reports were received for my signal, including K9FD (/KH6) reporting me at his sunset only to fade away after dark with an upward fade reported at KR7O followed by W7IUV. This undulation occurred on a long time scale of 20 to 30 minutes and went on for probably an hour. I was not hearing Merv well at all but there were a few peaks. Others, like W7IUV, reported no copy on Merv during this episode as well so the spot light was fickle and moving around. I completed a CW QSO with Rob, NC0B, and we spent a few minutes comparing notes just prior to this episode with K9FD and others in the West. Merv noted that Rob and I were both strong at his sunset. The key is going to be getting my peak in KH6 in sync with his signal moving back this direction. Some work in the early morning hours may be in order, which can be complicated to coordinate. W0RW was heard calling CQ on 473 but he was much weaker than normal while being reported as “blasting” into the Northwest at W7IUV. Reverse beacon reports at WZ7I were good in the later evening but the path to VE6 was not present or rain static was an issue or those nodes were down due to CQWW. It could also be a combination of all three of those events. It was an enjoyable session and fun to be in the trenches with so many operators. Let’s continue to grow this QSO activity. If you are currently using WSPR I would encourage you to step out of your comfort zone and arrange a sked or make a few blind calls. You may be rewarded. If you need help, please ask questions. I slept in this morning so there was no pre-sunrise activity for me.

Robert, KR7O, reported a very good session, offering the following comments and statistics:
“Good conditions and lots of QSO activity on JT9 last night with at least 13 stations copied, including K9SLQ and K9MRI. KA7OEI and CF7MAY stirred things up. Best conditions I have seen to KB5NJD with many JT9 decodes and good CW signals with a long QSB cycle. Could still see John’s trace on the waterfall during the lulls, so not a complete fade out.
Overnight WSPR, 13 spots with only single TC spots of K2BLA and K4SV. I was expecting better TC overnight based on the evening conditions.
K9FD – 75 spots, -9
KL7L – 53 spots, -9
VK4YB – 21 spots, -19 (0940-1236Z)“
Mike, WA3TTS, listened to WSPR, reporting that he heard “…21 overnight, incl K9FD 20 spots best -20 @ 1004, N6GN, 1 spot -25, W0YSE 3 spots all -27, KA7OEI 35 spots best -17 @ 0906. My 475 kHz version of the W1VD MF preselector worked well overnight.”
There were 162 MF WSPR stations reported on the WSPRNet activity page at 0030z. Regional and continental WSPR breakdowns follow:
Eden, ZF1EJ, continues to operate in a receive-only capacity as his station operates in the CQWW CW contest this weekend. He reported twelve WSPR stations including K9FD.
Martin, YV7MAE, reported three WSPR stations.
Laurence, KL7L, was up early for JT9 and submitted the following comments and statistics:
“…up at 0430 local to call CQ JT9 but no takers – I also saw half the VK4s qso – or a bit of it
I ran three transmitters over night all syncd to transmit in the same time slot –
XPQ was on my portable 30ft Sotabeam vertical and temp Variometer and 475kHz slapped against a gutter on the house and using the house Earth as the return as I would be using in “remote ops” – very temp but from the meter readings it looks like it will work – and Ive not added the cap hat cos of the high winds here, so its in its worst eirp config at the moment.
137/475kHz KL7L were running at legal EIRPs respectively and conditions looks like they are going the right way – we just need for it to open to the East now. Rudy decoded the 137kHz WSPR which is good going.“
At KL7L and using WSPR, Laurence shared two-way reports with VK4YB and K9FD (/KH6) and received reports from JA1PKG, JA1NQI/2, JH3XCU and ZL2AFP. Select DX report details can be viewed here.
Merv, K9FD (/KH6), spent time on CW near his sunset, reporting strong signals from North America that were stable and persistent until dark when levels dropped significantly. Merv’s CW signal ranged from no copy in the Northwest to slight copy at just under the noise floor in Texas. It was an interesting episode to say the least. Using WSPR overnight, Merv reported eleven stations including 7L1RLL. He shared two-way reports with VK4YB and KL7L. Merv received reports from 54 unique stations including 7L1RLL2, 7L1RLL4, JA1NQI/2, JA1PKG, JE1JDL, JH3XCU, ZF1EJ and ZL2AFP. Select DX report details can be viewed here.
Jim, W5EST, present “Pre-Sunset 630m QSB”:
“Today’s illustration shows K5DNL WSPR signal at medium angle on a short 430 km path from Oklahoma to w5est here in Little Rock, Arkansas 11/25/17. At center right, compare the WSPR bar at 2216z vanishing about 2217z with the full WSPR bar that decoded 2220z. (See waterfall areas “6” for 2216z and “0” for 2220z.)In the late fall afternoon, the sun’s descent was nearing the southwest horizon about 40 minutes before Little Rock local sunset (SS) later at 2258z. One would have expected the signal to have been invisible before appearing in the slot rather than the reverse as shown. So, interpreting it as pre-SS QSB seems justified.Why did this pre-SS QSB happen? I’d chalk it up to either ground wave anti-phasing with pre-SS sky wave, multipath anti-phasing in the sky, or to some non-uniformity in the pre-SS D-region absorption or E-region reflectivity.As to non-uniformity, however, sunset at altitude in either D- or E-region happened much later than local sunset in Arkansas. So it seems unlikely that some sudden disequilibrium caused a non-uniformity in either D-region or E-region to yield the QSB 40 minutes before sunset.Instead, it seems more likely that gradually declining absorption in the D-region under the late-day sun admitted more sky wave to the receiving antenna and that the QSB was caused by destructive interference (anti-phasing) of the signal with itself along more than one path–sky/ground or sky/sky.Occasional WSPR decodes earlier in the afternoon are consistent with the possibility of phase changes between two signals that led to constructive interference and those successful decodes even earlier than the QSB discussed here.GL on 630m in the daytime!”
