A review of this session’s S/N reports suggests a wild night, with massive variations in signal levels over very short time spans. Eric, NO3M / WG2XJM, reported that Ken, K5DNL / WG2XXM, “… went from +11 to -5 to +9 over 36 min period, then -1 to +10 in consec. cycles 15 min later.” Larry, W7IUV / WH2XGP, reported that the band appeared poor in the early evening, which was something that I also observed while looking over data. My opinion on this is that the band was slow to stabilize after dark but as the evening continued, single digit S/N reports were common from my station. It is possible that the higher latitudes are still somewhat impacted from the recent storm conditions. Laurence, KL7L / WE2XPQ, reported visual aurora at the end of the previous session. John, WA3ETD / WG2XKA, indicates that the high latitude transcontinental path was open in both direction from his station in Vermont to the Pacific Northwest, however. John was also spotted here with nice signal levels typical for this time of year. I’m not sure, however, whether those reports were successfully uploaded to WSPRnet as many station are having problems.
The geomagnetic field was quiet to unsettled through the session. The Bz component, as reported by the Space Weather Prediction Center, ranged between +/- 10 nT through the session and the solar wind continued to peak above 600 km/s through much of the session.
The Kyoto DST was generally stable through the session but negative.
John, VK2XGJ, sent the following capture of the Australian DST, which I will make an attempt to include in future reports:
Paul, W0RW / WA2XRM, was brave and operated QRSS120 through this session with reports from Garry, K3SIW in Illinois and Jim, W5EST in Arkansas. Jim sent several screen shots but I will post one that shows the signal stability through the selected time period, which appears to be near sunrise in Colorado.
Paul had the following comments, as posted on the 600-meter research group e-mail reflector:
WSPR activity dominated the session once again, with 85 MF WSPR stations observed on the WSPRnet activity page during the North American evening. Laurence, KL7L / WE2XPQ, reports that he operated 630-meter WSPR15 through the session but no reports appear in the database. Its unclear whether there were more upload problems or he simply had no reports due to the continued high speed solar wind stream.
Daytime activity was high, with numerous active stations spread across the US during the 6-hour period surrounding local noon for each station.
Joe, NU6O / WI2XBQ, operated at 5 mW ERP and had a very nice session, with three reports of his signal in the west with best DX reports from VA7MM at 956 km. Joe is currently working on a 500-watt linear amplifier that he hopes to have on the air for testing tonight.
Al, K2BLA / WI2XBV, had a strong session as he progressed to 1-watt ERP levels, with reports across North America, his best DX at WH2XGP in Washington state.
The 24-hour regional / continental WSPR breakdown follows:
Trans-Atlantic activity was limited to reports of DK7FC by WD2XSH/17:
EA8BVP continues to supply good reports for European signals, with SV3DVO making the cut during this session:
The trans-African path persists as well, with reports on Michel’s, FR5ZX, receiver on Reunion Island for DK7FC, EA5DOM, and SV8CS:
In the Caribbean, Roger, ZF1RC, and Eden, ZF1EJ, have a strong session. Roger reports upload problems from previous sessions and indicates that his antenna has been on a 300-degree heading over several days when reports were missing.
In Alaska, Laurence, KL7L / WE2XPQ, transmitted WSPR15 through this session but it appears that no reports were uploaded and he may be a casualty of the high speed solar wind.
In the Pacific, Merv, K9FD/KH6 / WH2XCR, had a good session but its interesting to see his reports essentially stop in the east at the Mississippi River. Merv had no reports from JA through this session, but he did report Phil, VK3ELV, and received reports from John, VK2XGJ, that did not upload to WSPRnet.
Phil, VK3ELV, was reported by two JA’s and WH2XCR through this session:
Other anecdotes and statistics for this session:
OM1II was soliciting QSO’s for the OM2015TITANIC special event station, operating on 472.2 kHz in the ON4KST chat/logger.
Spiros, SV8CS, reported a 2-way CW QSO with I6BQI.
Doug, K4LY / WH2XZO, is in the process of studying S/N reports as he is making some changes to his transmit antenna system. Perhaps Doug will allow me to publish details here upon completion.
Eric, NO3M / WG2XJM, reports that a release version of WSJTx can be downloaded here. This package contains WSPR2 and JT9, which are commonly used on 630-meters.
Dave, N1EA, reports that coast station WNE was QRV on 472 kHz at 0100z with maritime weather transmissions. This information came to Dave from Richard, AA1P.
There have been no CW sessions from WG2XIQ for a few days as schedules are shuffled and a storm system approaches. There is a high possibility that my station will be QRT for the next session.
