While there is over a month and a half before Autumn officially arrives in the northern hemisphere, operators are beginning to notice changing band conditions. This is one of those instances where change is a good thing because openings that have not been seen in months are beginning to show up, stations that have been QRT for the Summer are beginning to make plans for operating, and reports are improving for most stations. While I expect we will see the occasional “bump in the road” we seem to be heading in the right direction. Let hope for stable solar and geomagnetic conditions going forward, at least for some of the time.
Geomagnetic activity was somewhat active although quiet levels persist. The Bz has been variable and solar wind velocity was elevated for much of the session, exceeding 450 km/s. Protons were elevated to high levels for a few reporting periods during the daytime.
Roelof, PA0RDT, “connected the dots’ between solar flux numbers and performance on 472, which corroborates much of what we think we know already. The following was posted on the RSGB LF yahoo group:
There has been some remarks about the decent propagation of last
night. At the moment, solar flux is 71, which is 35 points below
what it was a week ago. This makes a lot of difference.
When you look at this graph:
you will find that over the year 2008 – 2010 solar flux figures
were below 80 at any time. This was the time that truly exceptional
propagation could be observed at LF, albeit not every night.
I hope this helps.

Phil, VE3CIQ, reports “Best inbound was XIQ at -22. Best outbound for me is XKA at +5. Still storm noisy here, but I like where this is going.”:
Roger, VK4YB, reports “Base noise mostly at -79 dBm. A few quieter periods has allowed WH2XCR to be decoded. Storms off VK6 and ZL has not helped.” He also notes that long haul reports are probably not far off and that a persistent noise floor that has been seen recently near -86 dBm would be nice. I think we will get there before the southern hemisphere heads into Spring conditions.
Larry, W7IUV / WH2XGP, reports that he decoded four WSPR stations and was decoded by thirteen unique stations with impacted receive conditions mostly due to a failed Flag antenna. I am guessing the wind took the antenna out again. Larry will be using an E-probe until he can get the Flag repaired.
Steve, VE7SL, reports that he heard five WSPR stations and was heard by nine unique stations. Steve shared twenty two-way exchanges with WH2XCR and he indicates that “things improving slowly”.
John, WA3ETD / WG2XKA, reports that all of the recent rain resulted in the need for a massive retune of his system. He is QRV during the day as this report is being prepared after making adjustments. He was receive-only overnight and heard WH2XGP on the high latitude transcontinental path.
Neil, W0YSE/7 / WG2XSV, reports that the directions switched a bit and conditions look a bit better. Neil’s comments follow:
“WG2XSV was heard by XCR 5 times, but by XPQ only ONCE this session. A switch in directions from last session.
Heard by: WH2XGP, AL7RF, NO1D, NU6O, VA7JX, VE7SL, W7RNB, WE2XPQ (AK), WH2XCR (HI),
Hearing: WH2XGP, VE7SL, WG2XIQ (TX) twice, WH2XCR (HI) only once”
Rick, W7RNB / WI2XJQ, had his maiden voyage on 472 WSPR during this session and he did pretty well, reporting stations in the Pacific Northwest, my station in Texas and WH2XCR in Hawaii. He reports numerous difficulties in getting the software to work properly but was able to make it work on an XP box however that machine crashed during the session. My suspicion is that automatic updates were on and Microsoft had a hand in this treachery. Rick reports that he plans on transmitting on even numbered days and receive on odd numbered days. I presume at this time that this is due to the lack of a TR switch but I have asked the question for a clarification:
Regional and continental WSPR breakdowns follow:
There were no reports from the trans-Atlantic, trans-Equatorial, trans-African, or Caribbean paths. UA0SNV and ZP4KFX were present but no reports have been filed at this time.
Laurence, KL7L / WE2XPQ, operated transceive during this session and was heard by VE7SL and WH2XCR. He also decoded Steve and Merv as well as others in the western portions of North America:
Merv, K9FD/KH6 / WH2XCR, had a strong night along the western edge of North America, including two-way reports at VK4YB and reception reports from VK2DDI. Merv also decoded VK3ELV near sunrise. I only wish W25EQT to the West was real:
