Propagation in North America was slow to develop in the early evening likely due to high QRN levels in the South but as in the previous session, those quickly dissipated after sunset due to a loss of heating. Joe, NU6O / WI2XBQ, also noted that the session started off a little weak from his station in northern California. The band was strong later in the evening and WA3TTS reported that WG2XXM was at single-digit S/N with the EWE pointed to the Northwest.
Geomagnetic conditions continue at quiet to unsettled levels. Just when we think we have returned to persistent quiet levels, a spike is observed and this seems to be recurring on a 12-15 hour cycle so far. The Bz is pointing to the South and solar wind has generally exceeded 600 km/s for much of the session but is currently averaging 550 km/s. DST values suggest that recovery many be approaching but Solarham is reporting another chance of G1 storm levels within the next 24-hours. These conditions seem to have had little detrimental impact to the mid and lower latitudes. They are creating problems for WE2XPQ, however.
Roger, VK4YB, reports a noise floor at -84 dBm to the Northeast and -85 dBm to the Northwest with no QRN from his station in Northeastern Queensland. These facts played a crucial role in reports by David, VK2DDI, in New South Wales who once again magically decoded WSPR signals from WH2XGP, WG2XXM, and WG2XIQ:
Larry, W7IUV / WH2XGP, also had reports from John, VK2XGJ:
Ken, K5DNL / WG2XXM, reports that he decoded three WSPR stations and was decoded by 27 unique stations, including VK2DDI. Ken had 24 decodes from WH2XCR and two from new station VE7IGH.
Larry, W7IUV / WH2XGP, returned to air after a station rebuild that turned out more complicated than originally planned. Testing and debugging is ongoing. Larry also upgraded to WSJT-X V1.7r7005 and made it through the session with no problems. He decoded seven WSPR stations and was decoded by 21 unique stations including VK2DDI.
Phil, VE3CIQ, had this to report:
“Started out with really big signals at sundown, but that was short lived.. Looks like a good run, spot counts nearing 200. Great to see the 4 bigger stations all on.”
Mike, WA3TTS, reported “Best XGP overnite as -17. I was hoping for a VE7SL decode, but cndx not quite good enuf.”
John, WA3ETD / WG2XKA, reported “+2 from WE2XGR/3” at 0125z, which was a significant report for that time of the evening. He added this morning:
“Conditions seem to be on the upswing, although still impacted by the noise of continuous, isolated pop-up TS in ME, VT, NH. Several higher powered stations out west were spotted here, and XKA was spotted by several while running ‘only’ 100W TPO due to a compromised radial system. Several early spots from locals in the 200-500 km range indicated extremely good sporadic conditions.”
Steve, VE7SL, reports that he decoded seven WSPR stations and was decoded by ten unique stations. There were no eastern reports.
Rick, W7RNB / WI2XJQ, provided the following WSPR reception and transmitting reports:
Edgar, EJTSWL, currently operating portably from Rolleston, QLD, has been reporting a number of stations and posting screen captures to dropbox. I have been unable to download screen captures from his dropbox links until today and am happy to present his view of VK4YB, VK5ABN, and VK3ELV:
There were two new stations during this session: AF5GM and VE7IGH. Both stations were originally reporting on the old frequency of 503.9 kHz but VE7IGH fixed the problem at some point and began making reports. AF5GM, who is located in West Texas, was still reporting the old frequency of 503.9 kHz and had no reports. A check of QRZ indicated no email address. When decoding with version 2.0, 2.1 or 2.11 of the WSPR2 software, the default is unfortunately the old frequency. On the left side of the window and below the water fall, the box marked “Dial” should be set to “0.474200” and the box marked “TX” should be set to “0.475700”. This is particularly important for stations using CAT to control their receivers.
Regional and continental WSPR breakdowns follow:
There were no reports from the trans-African, trans-Atlantic, or trans-Equatorial paths. UA0SNV was present but no reports have been filed at this time.
In the Caribbean, Eden, ZF1EJ, operated two stations once again and presumably in the same configuration as the previous session. Reports from each receiver/antenna combination seem to be relatively consistent through simple comparison. There were a large number of reports for each station:
Laurence, KL7L / WE2XPQ, operated both call signs once again with two receivers and two antennas. WE2XPQ was defined as “W1VD/AMRAD at 20ft wet trees” and KL7L was using the “L400b at 35ft or so in clear – hvy rain continues.” The lack of decodes for VE7SL and WH2XGP is interesting but they may have been far enough North to be under the auroral oval:
Merv, K9FD/KH6 / WH2XCR, had a strong session, evening being heard again here at my station. The path to Australia was pretty good as well. Seasons are definitely in flux:
