There is not a tremendous amount to report from this session. Propagation is still seeing an impact from the recent geomagnetic activity but activity is still very high and many spots, often very strong, are reported. Larry, W7IUV / WH2XGP reports that high latitude absorption has resulted in another night of no open path to stations in New England. Larry goes on to say that the path to KH6 appears to be doing very well, however, where his signal was reported by Merv, K9FD/KH6 / WH2XCR, one hour after local sunrise in Washington state.
The general consensus seems to be that while the session started very quietly, propagation was not as strong as previously observed but as Ken, K5DNL / WG2XXM, points out, conditions did seem to get better, at least at lower latitudes, as the overnight period here in North America progressed. This slight improvement seems consistent with the very slight improvement in the reported geomagnetic activity.
Daylight conditions were slightly improved compared to previous sessions, with persistent reports from WD2XSH/17 in Colorado. While fewer reports were submitted than during recent peaks, regular daytime reports were common through the afternoon here at WG2XIQ.
John, WA3ETD / WG2XKA, reports that John, W1TAG reported his ground wave signal over a path of 211 km throughout the afternoon.
Worldwide WSPR activity remained high throughout the day, with 71 stations reporting activity on MF WSPR during mid-afternoon in the central time zone of the US. Continental / regional WSPR activity breaks-down as follows:
Atlantic activity improved slightly with reports from VP9GE extending into New England once again.
ZF1EJ and ZF1RC continue to report a wide variety of stations across the US.
Reports by Michel, FR5ZX, on Reunion Island of European stations resumed during this session, including spots for G8HUH, DK7FC, SV8CS, and EA5DOM.
In Alaska, Laurence, KL7L / WE2XPQ, continues to remotely operate his station with some success to show for it. Laurence indicates that temperature will start to drop in Alaska near the end of the week which should help his signal a bit.
In the Pacific, Merv, K9FD/KH6 / WH2XCR, was in receive-only mode for the session and did a nice job hearing Rob, K3RWR / WH2XCC, in Maryland as well as Eric, NO3M / WG2XJM in western Pennsylvania.
Merv will likely be QRV at reduced power during this evening’s session. His amplifier lost a FET following what appears to be a power spike from his power supply which consists of a pair of 12-Volt 54-Amp computer server power supplies wired in series. While he did not have the proper replacement FET on hand, he is using a different value FET which will probably be OK at reduced power for a few days while spares are ordered and shipped. If you do own one of the amps that I build and you are not using a soft start power supply, be sure to power up the supply BEFORE physically connecting the power leads to the amp. The voltage spike on start up of some supplies can damage semiconductors within the amp. All further amps that I ship will be fitted with MOV’s to help suppress damaging spikes but that is not necessarily a cure all.
Doug, K4LY / WH2XZO, reports that his “antenna shoot out” continues with both the loop and transmit antenna showing 149 decoded signals through the session. Each antenna had one decode of Ward, K7PO / WH2XXP, representing the best DX of the evening. Doug will be away on a research project for a few days and his reports and signal will be missed.
Neil, W0YSE/7 / WG2XSV, reports that his antenna shoot out analysis is in progress. Neil also indicated that his signal was reported by 18 unique stations, 3 of which were new.
We were joined last night by W7PUA who seemed to give out a large number of reports over the session. Welcome aboard.
My morning CW session did not yield any additional QSO’s and there was a miscommunication about my morning sked due to changing local weather, so it did not take place. I returned to WSPR a little early, around 1150z.
So this was a very uneventful session aside from the large number of participants and the return of trans-African propagation. As the song says, “Mama said there’d be days like this…”
