Radio: it's not just a hobby, it's a way of life

Current Operating Frequency and Mode

OFF AIR for storms, probably for much of the week if the forecast holds

Rough night as geomagnetic conditions drop to levels not seen in a long time but VK4YB -> JA, WH2XGP

IMPORTANT REMINDER: Neither 630-meters nor 2200-meters are open to amateurs in the US yet.  Please continue to be patient and let the FCC finish their processes.  Click here to view the proposed “considerate operators” frequency usage guide for 630-meters under Part-97 rules that was developed with the input of active band users.

Wow – it has been a long time since we have observed band conditions with such high noise and erratic geomagnetic conditions which is saying a lot as the last few weeks have been very trying for low band radio operators.  Lightning conditions brought tremendous noise to the band during the late evening and overnight over a wide area and many stations reported that they heard very few or even no one by this morning.

12-hour North American lightning summary


Geomagnetic conditions reached G3 storm levels as the Kp reached 7.  The Bz pushed strongly to the South, reaching levels in excess of -15 nT for long durations.  Proton levels were elevated through much of the session, reaching levels in excess of 60 protons/cc which is extreme.  Both Bz and proton counts have relaxed a bit this morning.  Solar wind velocities reached above 400 km/s during the peak of activity following the CME interaction but have since returned to calm levels, averaging near 370 km/s.  DST values are as low as have been observed in quite a long time, approaching -200 units on the Australian measurement.  The difference from the previous session with the Kyoto measurement is also very impressive.




Doug, K4LY / WH2XZO, reported that he decoded one WSPR station and he was decoded by eleven unique stations.

Neil, W0YSE/7 / WG2XSV, reported that he was decoded by ten unique stations,”…all along western NA + HI. Hrd only XCR, XBQ, & XGP.”

Al, K2BLA / WI2XBV, reported that his noise was only moderate but  he heard no stations after a brief listening session this morning.  Its possible that propagation was so poor that the high noise from the central US was not reaching Florida.

Dave, N4DB, reported that he was only active for about an hour due to local thunderstorm conditions.  He decoded four WSPR stations during that time frame.

Mike, WA3TTS, reported that “only XXC, XZO and XGR/3 hrd overnight with NE EWE antenna to attempt noise null, rather futile…”

Hideo, JH3XCU, provided links detailing VK -> total JA DX and VK -> JA peak S/N for the session.

Roger, VK4YB, reported that “Only Merv, WH2XCR able to penetrate the cacophony of QRN from triple storm systems in the Tasman Sea. The space weather event had little effect in this region with paths to North America and Japan in evidence.”  Roger received reports from 7L1RLL4, JA1NQI/2, JA3TVF, JH3XCU, TNUKJPM, and WH2XGP and he shared two-way reports with WH2XCR.

John, VK2XGJ, reported his first decode of WH2XCR at 0910z with a signal of -21 dB S/N.

Larry, W7IUV / WH2XGP, reported very high noise at his sunset but he managed to provide reports for five WSPR stations including VK4YB and he received reports from twelve unique stations.  As W7IUV, Larry provided reports for two WSPR stations.

My activity was limited to CW prior to sunset  and through the evening.  The band was clearly becoming noisier as the evening progressed but was manageable for much of the operating period.  With storms expected overnight, I secured the station at bed time.  The coming week will be hit or miss due to some flavor of storms expected each of the next seven days.  Timing will be key and as long as storms are not expected overnight or during the evening I am comfortable with being on the air.

Regional and continental WSPR breakdowns follow:

North American 24-hour WSPR activity


European 24-hour WSPR activity


Japanese 24-hour WSPR activity


Oceania 24-hour WSPR activity


Eden, ZF1EJ, who was expected to be in a receive-only capacity through the weekend, had no reports for this session.

Laurence, KL7L / WE2XPQ, received reports from only WH2XCR as high latitude geomagnetic conditions deteriorated very early in the session.  He indicates that he was transmitting a 20% duty cycle.

WE2XPQ 24-hour WSPR activity


Merv, K9FD/KH6 / WH2XCR, provided reports for WE2XPQ and VK3HP and he shared two-way reports with VK4YB.  Merv received a report from VK2XGJ.  DX report details can be viewed here.
