Current Operating Frequency and Mode

OFF AIR for storms - just one more night - should be QRV Saturday night!

High QRN reported across North America as quiet prevails in Oceania; Geoeffective coronal hole expected today; Another random trans-Atlantic report but consistency in the Pacific is improving; First time reception of VK4YB at WG2XSV

There was probably no escaping QRN during this session for North American stations as storms ranged from Mexico through the central US, across the Midwest and into New England.  WA3TTS reported S8 noise levels during the evening on the northwest, southwest and northeast paths.  A check to the southeast briefly  yielded some positive results but quickly fizzled as noise levels there were just as bad as other directions.  Oceania was quiet for a change, however, as was reported by VK4YB.  Roger added that propagation went quite long for parts of the evening.

11-hour North American lightning summary


Geomagnetic conditions were quiet through the session although the Bz continues to point slightly to the South.  Solar wind velocities are down from the previous session, averaging 365 km/s this morning.  DST values have, in fact, improved during this session, riding the center line and in several instances pushing to positive levels on one indicator.  Solarham is reporting that a coronal hole is becoming geoeffective sometime today so expect changing geomagnetic conditions within the next 24-48 hours.





Trans-Atlantic opening were limited to a “one-off” report for a Florida station.  Report details can be viewed here.


Paul, N1BUG / WI2XTC, reported increasing QRN through the evening, reaching high levels before subsiding by morning.  He decoded eight WSPR stations including WD2XSH/20.

Al, K2BLA / WI2XBV, reported a “mediocre session” with increasing noise conditions through the evening that subsided by morning.  Al indicates that he decoded eight WSPR stations and he was decoded by 24 unique stations including reports from WH2XCR (best -20 dB S/N) and VE7SL.

Trans-Pacific report details, excluding KL7 and KH6, can be viewed here.

Hideo, JH3XCU, posted links to two tables showing PAC -> total JA DX  and PAC -> JA peak S/N for the session.

Roger, VK4YB,  reported the “Return of classical “Bactrian” conditions. For those not familiar with camels, the Bactrian has two humps. The Dromedary has only one.  The second peak was as good as the first but not good enough to meep Steve, VE7SL[for a CW QSO attempt]. His best report was a -16.  Noise was low throughout. VE6XH was not QRV on 160, and did not decode my sigs on 630m.”  Roger provided reports for WD2XSH/20, WE2XPQ, WG2XXM, WH2XCR, WH2XXP, and WI2XBQ.  He was reported by VE7BDQ, VE7SL, W7IUV, WG2XSV, WH2XCR, WH2XGP, and WI2XJQ.

John, VK2XGJ, reported a nice array of early reports:

Ken, K5DNL / WG2XXM, reported that he decoded five WSPR stations and was decoded by 52 unique stations including VK4YB, WE2XPQ, and WH2XCR.  He indicates storm QRN originating to his North.

Ward, K7PO / WH2XXP, received reports from 49 unique stations including VK4YB, VK2XGJ, EJTSWL, and ZL2AFP.  Ward also indicates that he has deployed an addition two miles of radials under his antenna.

Larry, W7IUV / WH2XGP, provided reports for thirteen WSPR stations including VK4YB and was decoded by 23 unique stations including ZL2AFP.  As W7IUV, Larry provided reports for thirteen WSPR stations including VK4YB.  Larry indicates that his PA tripped off again overnight but on inspection this morning nothing was amiss.

Joe, NU6O / WI2XBQ, provided reports for nine WSPR stations and was decoded by 23 unique stations including VK4YB.

Rudy, N6LF / WD2XSH/20, provided reports for eleven WSPR stations and was decoded by 36 unique station including VK4YB and VK2XGJ.

Neil, W0YSE/7 / WG2XSV, reports that he decoded Roger, VK4YB, for the first time during this session with two reports.  He provided reports for eleven WSPR stations including VK4YB and was reported by 36 unique stations.  Neil provided these comments:

“I got a VERY NICE SURPRISE this morning. I finally heard Roger/VK4YB !! I did not think my RX capabilities were ever going to be able to hear that distance !!”

Rick, W7RNB / WI2XJQ, reports that while the Mississippi river has returned to brick wall status, he managed to decode VK4YB.  He provided reports for twelve WSPR stations including VK4YB and he received reports from 23 unique stations.  Rick’s unique report details can be viewed here.

I briefly operated WSPR during the evening but operator error resulted in the system being off line for much of the night.  It was a noisy night so I don’t believe that much was lost by missing most of the overnight period.  This morning I called CQ on CW from around 1102z through 1215z and restarted after 1300z for daytime calls.  QRN is low at the moment but storms are expected later today and will likely impact operating.

Eden, ZF1EJ, provided reports for eight WSPR stations and he was reported by twelve unique stations including WH2XCR.

ZF1EJ 24-hour WSPR activity


Laurence, KL7L / WE2XPQ, reports that he may be experiencing more Internet upload problems which may have stranded a few reports during the session.  This session was significantly better than the previous, even with potentially missing reports.  He received reports from VK4YB and shared two-way reports with WH2XCR.  Laurence indicates that he was QRT early for some VLF experiments.   DX report details can be viewed here.

WE2XPQ 24-hour WSPR activity


Merv, K9FD/KH6 / WH2XCR, saw a return of JA station reports, including 7L1RLL4, JA1NQI-2, JE1JDL, and JH3XCU, who provided late, sunrise reports for Merv.  He shared two-way reports with WE2XPQ and VK4YB, the latter of which also engaged in late-session reporting.  Merv also provided reports for ZF1EJ while receiving reports from VK2XGJ and ZL2AFP.  Eastern coverage was largely impacted by noisy conditions in North America, but K8PZ managed to hear Merv overnight.  DX report details can be viewed here.
