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

Variable propagation across the globe resulted in isolated long haul openings; Strong Texas storms mean big noise in North America; KP2XX providing reports for North American and Caribbean stations; WI2XUF application granted after long wait

Noise was once again a dominant feature impacting many stations.  In fact this morning during a CW QSO attempt with VK4YB, Steve, VE7SL, noted that QRN was registering at S9+ 15 dB.  I can’t imagine what it was like here since the storms were overhead.  My station was very much secured.

Geomagnetic activity was quiet for a second consecutive session.  The Bz continues to point to the North very near the center line and solar wind velocities are largely unchanged from the previous session, averaging near 435 km/s.  DST values were stable for much of the session although they trended downward as sunrise  approached North America.




Roelof, PA0RDT, reported that propagation continues at depressed levels but he did have aural copy on Joe, VO1NA, who was operating CW on 477.7 kHz at 2345z.



Luis, EA5DOM, reported his first QSO with EA4GHB using QRSS3.  Luis explains:

“Finally we managed to make our first QSO last night. Signals were loud enough for CW but Alberto had a delay in the PA and so we went to QRSS3.  Hopefully he will keep active tonight in QRSS for anyone to try. The next station with conditions for QSO is Francesc, EA3AER which is actually 300w and improving antenna”

There was only one trans-Atlantic report for the session and it was “out of the blue”.  Report details can be viewed here.


Paul, N1BUG / WI2XTC, reported low QRN prior to sunrise which increased to moderate levels through the evening finally subsiding slowly by morning.  Paul decoded eight WSPR stations including WH2XGP in Washington state.

Al, K2BLA / WI2XBV, reported low to moderate QRN this morning, decoding six WSPR stations and receiving reports from 29 unique stations, five of which were at a distance of at least 4000 km.  Those stations include WH2XCR and VE7BDQ.

Rick, W7RNB / WI2XJQ, provided reports for nine WSPR stations and he received reports from 21 WSPR stations.  Rick’s unique report details can be viewed here.

Dave, N4DB, reported that he decoded ten WSPR stations, two of which were greater than 3000 km distant.

Mike, WA3TTS, reported that he appears to have been the most easterly station in the US to report WH2XCR and VE7BDQ during  this session.  Storm QRN impacted a number of typical reporting stations.  He included these additional comments and statistics for the session:

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

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

Roger, VK4YB, reported that, “The band was quirky tonight. Very good reports from all over VK, including some -3 S/N from VK6XT at 3441 km, off the back of the beam. Reports were down from Hawaii and almost non-existant from NA. QRN remained low throughout. VE6XH stats: 160m 4 spots, best -9, 630m 2 spots, best -24.”  Roger received reports from VE6XH, WE2XPQ, and WH2XCR.  He provided reports for WG2XXM, VE7BDQ, WH2XGP, WH2XXP and WH2XCR.

Ken, K5DNL / WG2XXM, reports that he decoded four WSPR stations and was decoded by 59 unique stations including VK4YB, KP2XX, and the previously reported LA2XPA/2.

John, VE7BDQ, provided reports for ten WSPR stations and he was decoded by 23 unique stations including VK4YB.

Ward, K7PO / WH2XXP, received reports from 53 unique stations including JA3TVF, VK2XGJ, and VK4YB.

Larry, W7IUV / WH2XGP, provided reports for ten WSPR stations and he was reported by 53 unique stations including VK4YB and VK2XGJ.  As W7IUV, Larry provided reports for nine WSPR stations.

David, G0MRF, submitted this note about a recent article about charged particle depletion following a solar storm and might offer some explanation as to why poor band conditions are observed during the calm geomagnetic conditions following a storm:

“A piece of interesting research from NASA today into electron density variations following a CME.


‘The 2014 geomagnetic storm was a result of two powerful Earth-directed CMEs. The storm initially produced patches of extra electrons in the ionosphere over northern Greenland, as usual. But just south of these patches, the scientists were surprised to find broad areas extending 300 to 600 miles (500 to 1,000 kilometers) where the electrons were “almost vacuumed out,” in the words of Per Hoeg of the National Space Research Institute at the Technical University of Denmark, Lyngby. These areas remained depleted of electrons for several days.'”

David, N1DAY / WI2XUF, has finally had his application granted after a very long wait.  Its unclear exactly what this might mean for other active applications following the recent R & O publication.  I continue to maintain the position that, for now, parties interested in filing a Part-5 application should stand by.  We are entering Summer band conditions so waiting a few weeks or even a month or two won’t make much difference and it will give the FCC an opportunity to sort out Part-97 implementation procedures.  Save your $65 for now.

Eden, ZF1EJ, provided reports for six WSPR stations and he received reports from seventeen unique stations including WH2XCR and KP2XX.  Noise was likely a very big factor in Eden’s hearing capability through the session.

ZF1EJ 24-hour WSPR activity


Jim, KP2XX, located on St. Thomas, VI, was listening for stations during this session, providing reports for five WSPR stations.  Jim has shown up on the map in the past but I believe that this may be the first time that he has actually provided reports for stations.

KP2XX 24-hour WSPR activity


Laurence, KL7L / WE2XPQ, reported after start up that his system loading looked abnormal so its possible that weather conditions or even a real problem exists with the antenna requiring physical inspection.  Propagation was a bit depressed compared to the previous session, particularly with stations in the western areas of North America.  Laurence managed to provide reports for VK4YB and he shared two-way reports with WH2XCR.  Report details can be viewed here.

WE2XPQ 24-hour WSPR activity


Merv, K9FD/KH6 / WH2XCR, confirmed Internet problems late in his previous session.  During this session he shared two-way reports with VK4YB and WE2XPQ.  He provided reports for ZF1EJ and was reported by 7L1RLL4, JH3XCU, and VK2XGJ.  He also reported WI2XBV in Florida and was reported as far East as WA3TTS near Pittsburgh.  DX report details can be viewed here.
