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

Current Operating Frequency and Mode

OFF AIR but will be QRV on CW somewhere between 472.5 kHz and 475 kHz after dark

SCHEDULED ACTIVITY: CQ 474.5 kHz CW by 1030z through sunrise most days, WX permitting

Make that seven JA’s for WE2XPQ; WH2XGP receives report from JA1NQI-2 for second consecutive session; WG2XKA trans-Atlantic reports in Europe; JA and VK paths persist at WH2XCR

– Posted in: 630 Meter Daily Reports, 630 Meters

It was another impressive night on 630-meters.  WG2XKA made it across the Atlantic to be reported by three stations in Europe, WH2XGP made it across the Pacific to be reported for a second consecutive night by JA1NQI-2, WE2XPQ was reported by seven JA stations in a single session, WH2XCR received reports from two JA stations and was reported in VK as well as providing reports to VK stations and the list goes on and on, not even taking into account the impressive reports within continental Europe, Australia and North America.

Geomagnetic conditions were quiet but elevated once again.  The Bz was variable and solar wind velocity has returned to levels in the low category, below 400 km/s.

Larry, W7IUV / WH2XGP, experienced a second night of Pacific crossings that has sparked excitement on both sides of the ocean.  In addition to his report from JA1NQI-2, Larry reports that he decoded ten stations, two of which were from Canada and he was decoded by 45 unique stations, nine of which were Canadian and one was in Japan.

Additional statistics, anecdotes, comments and information:

Ken, K5DNL / WG2XXM, reports that he decoded eleven stations, three were Canadian stations and he was decoded by 45 unique stations, where nine were Canadians.

I called CQ on 474.5 kHz CW shortly after sunset in Texas for 15-20 minutes.  No additional QSO’s were reported.  I am hoping to get back into the routine of regular CW QSO’s.  This weekend will hopefully see the return of activity by Steve, KF5RYI, using my second station capability, as WG2XIQ/1.

Jim, W5EST, provides this interesting discussion entitled, “TESTABLE RULE OF THUMB FOR N.Am.-VK PROPAGATION?”:

The last month on 630m has witnessed historic N.America-to-Australia and VK-to-N.America milestones. Even though we have missed ZL from this season’s 630m activity, this is a time of increasing VK 630m activity and demonstrable long path equipment readiness. Among others, think of Phil VK3ELV, John VK2XGJ, David VK2DDI, Roger VK4YB, Justin VK7TW.

Until this last month, the possibility of successful VK 630m WSPR transmissions into North America had long been a matter of conjecture. This blog on Feb. 22 noted the annual asymmetry of storm seasons in the context of overall symmetry between the opposite seasons in the N. & S. Hemispheres.

Sufficient 630m propagation examples of February-March N.Am.-VK symmetry of hemispheres are finally at hand as we near the upcoming equinox.  Six WSPR2 decodes comprise the evidence, 6 months after Aug. 15, 2015 when N.Am.-VK propagation began late last summer before the last equinox mini-season.  We will see how long the present VK-N.Am. mini-season lasts. For now, hearty congratulations to Phil, John, Laurence and Larry!

Predicting 630m trans-Pacific trans-hemispheric WSPR decode occurrences presents a worthy challenge to us amateur experimenters. Tomorrow I’m going to review a N.Am.-VK long path Rule of Thumb in hopes that future blog posts can marshal data and evaluate it.  Let’s see what we can learn!
