It was a noisy night for many in North America as storms in the Gulf of Mexico once again pushed eastward. The noise was by no means a deal-breaker here in Texas, however. Turning of one of the receive loops broadside to the storms yielded reports for John, WA3ETD / WG2XKA, in Vermont and Doug, K4LY / WH2XZO, in South Carolina who had made adjustments to his top loading but ran out of daylight before he could finish the tuning. As a result, he operated with reduced power at an estimated 500 mW ERP. Curiously, however, reports from northern stations were less optimistic. John, WA3ETD / WG2XKA, in Vermont noted that the band seemed flat and while he had a few reports from the Pacific Northwest, his spot numbers were the lowest of the season. John also noted that he was experiencing a bit of a thaw which might suggest increased environmental losses. Larry, W7IUV / WH2XGP, reported poor conditions from Washington state with high noise and degraded propagation. Examination of reports for my station suggest that while some reports might be down 3-6 db S/N, the session seemed consistent with most other nights that experienced above average noise conditions.
The geomagnetic field was quiet, in fact more quiet than has been experienced in over a week. The Bz was northerly through much of the session but shifted to the south overnight. Solar wind remained low through the session at around 320 km/s.
Mike, WA3TTS, reported that Frank, K3DZ / WH2XHA, was operating QRSS3 on 476.700 kHz. Mike also confirmed that “MP” was no longer operating QRSS6 on 475 kHz. VE3OT reported on LOWFER this morning that “MP” had a blown FET.
Europeans experienced another session of strong JT9 activity. Participants include but are not limited to the following: OR7T, SV8CS, DC1RJJ, DG3LV, DL6II, SV3DVO, F6CNI, LA3EQ, F5WK, YO2IS, OM1II, DF8UO, DL4YHF, IW4DXW, G3KEV, and SP9DNO. I have seen numerous QSO transcripts for this session but will refrain from trying to post those details until I can figure out how to do so most efficiently. JT9 QSO’s were plentiful, however.
Roelof, PA0RDT, reported on the RSGB “blacksheep” reflector that the normal CW signal of Joe, VO1NA, was visible throughout the European dark period, peaking around 0200z.
The WSPRnet activity page reported 76 MF WSPR stations as of 0240z. As in the previous session, I did not show up in the list in spite of actually transmitting at 30% as well as providing reception reports so the actual number of participants was higher. One new receive station was observed during the session, KB0BRY. There was also a new station in the north that executed a poor band change, which ultimately polluted the MF WSPR map. Please be sure to set to “IDLE” or turn off “Monitor” and wait for the current cycle to complete before transitioning to a new band. It otherwise makes the handling of data challenging. Thanks!
Regional and continental WSPR breakdowns follow:
There were no trans-African reports for this session.
AA1A provided two reports for DK7FC on the trans-Atlantic path:
In the Caribbean, Eden, ZF1EJ, was limited by Gulf storm noise but was successful in providing a few reports:
In Alaska, Laurence, KL7L / WE2XPQ, was reported by JA1NQI-1 in addition to the usual stations in western North America and Hawaii. KL7L was designated as receive-only. Laurence indicates that he also operated OPERA32 on 137 kHz at 1.4 KW, which was unsynchronized with his operations on 630-meters. This resulted in de-sense of KL7L and explains the spot disparity between WH2XCR’s reports of WE2XPQ and KL7L’s reports of WH2XCR.
In the Pacific, Merv, K9FD/KH6 / WH2XCR, saw a restored path to both JA1NQI-1 and VK2XGJ in addition to reports from the mainland US and Alaska. Presumably storm noise limited reports coming from east of the central US:
In very hot Australia, Phil, VK3ELV, has returned to operation with reports from JA1NQI-1 and JH3XCU after the reporting period in the previous session:
Additional anecdotes, statistics, comments or information:
Jim, WB5WPA / WH2XQC, reported spots from K3SIW/1, NX0P, W0JW, W5EST, W9MDO, WA3TTS, WB0VAK, WG2XIQ, WG2XJM and WH2XRR while running 5-watt TPO to the Edginton loop located in a 30-foot by 50-foot backyard.
Eric, NO3M / WG2XJM, indicates that he was reporting Ward, K7PO / WH2XXP, well before sunset in Arizona.
Jim, W5EST, provided the following session profile for Vernon, VE4XC:
“Vernon VE4XC activates 630m WSPR reception from Winnipeg, Manitoba. He operates currently the northernmost central Canadian receiving site. This means he is able to monitor 1-hop propagation on the “northern path” in any direction when transcontinental reception between a station farther east and one farther west like XGP-XKA likely involves two such hops. His 630m cockpit assesses southern USA signal penetration far northward as well.
Vernon’s best distance recently: Merv’s 2 watt WH2XCR from Molokai provided VE4XC two distant decodes Jan. 8 at 6096 kilometers distance: -30dB 0832, -27dB 0942z.
Vernon’s station reception profile spans Canada and USA without Alaska in last 2 weeks. Since his database WSPR spots show for selected nights and portions of nights, this profile combines intervals from different days and gives SIQ* for WG2XXM only.
Northern path: At VE4XC, WH2XGP SNR was down about 8dB compared to WG2XXM SNR (median peak-SNR difference over 8 days: 5.5dB down less 3dB for 2x TX XGP power at same distance). This suggests that the E/W northern path was ~8dB worse than the N/S path from XXM. (It’s also possible VE4XC’s antenna pattern favored XXM.)”
