This session was one of those weird ones. Band performance depended on where you were located and even then there were exceptions to the rule. The “diode effect” was active for many stations, particularly in the West on the trans-Pacific path. The path to JA also showed some life. It was generally quiet here in the evening and overnight aside from a storm sitting on the southern border of Arizona and New Mexico. It was easy enough to steer receive antennas around that one. Roger, VK4YB, reported that it was still noisy in Australia due to more storms in the Tasman sea, which is unfortunate since propagation was very good to North America.
There was a lot of red on the Kp graph over the previous few session but now it seems that more consecutive periods of unsettled conditions are beginning to string together. The Bz is not nearly as South-pointing as it has been, although solar wind velocities are currently averaging 625 km/s, down only slightly. DST values are slightly improved and some additional overnight reports at WE2XPQ near Anchorage suggest that the ring currents may not be as significantly impacted as one might think. We won’t know for a few days:
Doug, K4LY / WH2XZO, started the evening indicating the presence of early reports from the Pacific Northwest: “Surprised by this early decode- 2016-09-30 02:08 WH2XZO 0.475650 -26 0 EM85wb 2 WH2XGP DN07dg 3385 305.” This morning he added, “After a surprising 4 decodes by XGP just past his sunset, things returned to noisy normal- 9 decodes and decoded 24. Using SNR on other RX antenna resulted in no decodes.”
Ken, K5DNL / WG2XXM, reports that he decoded six WSPR stations and was decoded by 39 unique stations including WH2XCR (80 reports, best at -7 dB S/N) and WE2XPQ.
Roger, VK4YB, issued a “code 4” with great propagation but because of local storm noise, he was not hearing much. He adds, “…Similar to last night. Propagation is good. Lots of Tx reports but not a single Rx spot. No, not even a VK! can make it through the static.” He also reports possible first-time reports from WW6D. Roger’s statistics follow:
“Rx: DX None ! Only vk3elv and vk3hp could make it through the wall of QRN
Tx 1*wh2xnv (-27) 3*wh2xgp (-25) 123*ve7bdq (-21) 4*wi2xjq (-23) 15*ve7sl (-21) 2*ww6d (-28) 2*wi2xbq (-18) 8*we2xpq (-25) 35*wh2xcr (-11) 1*jh3xcu (-28)”
Larry, W7IUV / WH2XGP, reports that he decoded ten stations overnight using the eastern BOG but switched to the western receive antenna before sunrise to catch VK4YB. Larry was decoded by 33 unique stations and indicates that propagation was not as good as last week.
Ward, K7PO / WH2XXP, was decoded by 41 unique stations including JH1INM:
Rick, W7RNB / WI2XJQ, decoded ten WSPR stations and was decoded by sixteen unique stations. He provided these comments:
“Howdy — had a decent night, noting a couple of new ones, but nothing really stands out that would make the session exceptional — noise early in the session but XIQ came through quite early, at 02:30, so the band is changing pretty rapidly. Many spots of XCR, and VK4YB is consistent now. “
Nicolas, F4DTL, operated a CW beacon overnight with good success. He offers the following comments on the RSGB-LF reflector:
“Hello all, im testing my new automatic beacon this evening.
476,200 QRSS3 50W
Built in a small size (in a old CB Midland 4001) power by 2x IRFP450A. The frequency and the key are piloted by DDS and Arduino inside. No PC only 24V and my antenna.”
He received a few reports and screen captures which follow:
Tom, DK1IS, reports “2045 UTC: good audible reception here in JN59WK. Rig: remote Perseus with active whip, your signal -113 dBm resp. S4, SNR = 17 dB”
Stephan, DK7FC, had the following comments about the recent activity of RN3AGC on the RSGB-LF reflector:
“RN3AGC is now RXing on MF, having very good results. I always thought the path to Moscow is extremely hard to cross on MF but the results look promising for many stations.”
Once again I took a passive role during the evening and overnight, mostly out of curiosity for propagation that the recent geomagnetic storms might generate. It was a strong night, with many early reports in the Pacific Northwest with CW levels at VE7SL and many locations around North America, plus WH2XCR in KH6. My transmit reports can be found here and my receive reports can be found here. It was an “easy listening” session with low noise and the receive antenna was moved from Northeast to Northwest around 0500z. This morning I cancelled my CW sked due to a sinus headache so there were no morning activities to report today.
Regional and continental WSPR breakdowns follow:
There were no reports from the trans-Atlantic or trans-African paths.
Eden, ZF1EJ, may have experienced excess QRN from storms on the Atlantic coast at the main receiver using the LPA antenna as he did not decode WH2XGP. The LPA and associated receiver have historically been more robust although the large aperture and lack of controlled directivity make it more susceptible to QRN and QRM. The second receiver and loop were directed to the Northwest and were able to hear WH2XGP. There was no apparent opening the KH6 during this session.
Laurence, KL7L / WE2XPQ, experienced a slight improvement over the previous session as more signals are beginning to sneak in under the auroral oval and Laurence is heard a little further South. Laurence reports less aurora than the previous session but absorption was still present at most angle:
Merv, K9FD/KH6 / WH2XCR, experienced a JA explosion with reports from 7L1RLL_4, JA1NQI-2, and JH3XCU. Merv also decoded VK3ELV and shared two-way reports with VK4YB in spite of local QRN in Queensland. It was also a strong night in North America and Alaska. Merv’s recent changes so that he can receive again are really paying off:
