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

Better night on the air in spite of high-speed solar wind and more terrestrial storms in the southern and midwestern US; Trans-Pacific path between Oceania and North America returns and VK -> JA path continues to produce results

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.

Noise continues to complicate band activity as storms rage from Mexico through the Midwest to the southeastern US.  Its tough to steer receive antennas when lightning-baring storms are in every direction but the session was not a total bust.  Propagation seemed better on both domestic and long-haul trans-Pacific paths and activity was probably a bit better than the previous session.

11-hour North American lightning summary


Geomagnetic activity returned to elevated-quiet levels with the Bz turning around to the North after quite a bit of variability over the previous 24 hours.  Solar wind velocities decreased to moderate levels briefly but have generally averaged above 600 km/s.  The DST “free fall” has leveled off but persists at negative values.




Al, K2BLA / WI2XBV, reported high noise this morning, only decoding one WSPR station.

Ken, K5DNL / WG2XXM, reported down band conditions and activity.  He decoded two WSPR stations and was decoded by 38 unique stations including WH2XCR, ZF1EJ and three Canadian stations.

Dave, N4DB, reported that the band was slightly better overnight as he decoded six WSPR stations including ZF1EJ who was his best DX for the session.

Mike, WA3TTS, reported that at “About 0500 the propagation started to improve and WG2XXM started to decode here fairly well, although the QRN was still high. About the same time WH2XND was decoding on 2200m. Although for some reason my 2200m spots were not accepted by the wspr2 db. I tried a manual upload and got an “invalid grid” message.  Best overnights on the NW EWE antenna:”

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

Roger, VK4YB, reported “QRN slightly higher than yesterday but still quite mild. Merv, WH2XCR is back with a -10dB S/N. Highlight was 2 spots from Larry, WH2XGP. Obviously that antenna is working Larry!  JA path continues to perform despite QRN from a storm system Eastward of Japan.”  Roger’s complete trans-Pacific / long haul receive list includes 7L1RLL4, JA1NQI, JA1NQI/2, JA3TVF, JH3XCU, WH2XCR, and WH2XGP.

Larry, W7IUV / WH2XGP, reported that he has reversed his receiving directions for both of his stations with WH2XGP receiving to the West and W7IUV listening to the East.  He provided reports for six WSPR stations including VK4YB and he received reports from 21 unique stations.  As W7IUV, Larry provided reports for four WSPR stations.

It was definitely noisy but after several days off air I didn’t care.  I started the session with a few CQ’s on 474.5 kHz CW but no calls or reports were received.  I didn’t expect much as the activity was impromptu and I didn’t advertise.  I started before sunset with ground wave in mind knowing that once darkness arrived the noise level was going to skyrocket.  I transitioned to WSPR prior to sunset and it was obvious that the band was in better shape than what had been reported in previous sessions.  S/N levels were impacted by QRN, of course, but the band was open over a relatively large area of North America.  My transmission report details at 17% transmit duty cycle can be viewed here and my reception report details can be viewed here.  I’m continue to be very happy with the Monitor Sensors transverter.  My opinion of it’s receive capability compared to the Heathkit HD-1420 receive converter is that the transverter is far superior.

Eden, ZF1EJ, experienced a better session, providing reports for three WSPR stations and he received reports from five unique stations including WH2XCR.

Laurence, KL7L / WE2XPQ, also experienced a much better session, providing reports for three WSPR stations and receiving reports from six unique stations.  He shared two-way reports with WH2XCR and those report details are included with Merv’s report below.

Merv, K9FD/KH6 / WH2XCR, provided reports for ZF1EJ, VK3HP and VK5FQ and he shared two-way reports with WE2XPQ and VK4YB.  He received reports for VK2XGJ.  Merv’s DX report details can be viewed here.
