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

Current Operating Frequency and Mode

OFF AIR; QRT Thursday night but back Friday morning by 1100z

Propagation continues to improve as noise increases; ZL1AKI first ZL receive station in over a year; More details on VK2FPQ crystal set; Daily reports through the summer; An ARRL Field Day demonstration opportunity for 630-meters

The band was open and signals were strong for the most part, particularly to destinations out to about 1800 km.  QRN played a role during this session, however, with some paths  down 3-6 dB as a result.   Geomagnetic conditions were generally quiet but elevated and solar wind velocities peaked above 600 km/s during the session.  Current solar wind velocities are averaging 575 km/s.  The Bz has been variable, pointing North and South through the session and DST values have fallen once again.

Phil, VE3CIQ, reports that he dropped his power by 3-dB and is still achieving the same distances.  Phil decoded five WSPR stations and was decoded by ten unique stations.

Larry, W7IUV / WH2XGP, reports that his session from Washington state was a bit better than the last, with an open path to WH2XCR once again and a good path to the East coast.  Larry decoded six WSPR stations and was was decoded by 19 unique stations.

Neil, W0YSE/7 / WG2XSV, suggests that while reception was poor in Vancouver, Washington, the spotlight may have contributed to reports at WE2XPQ in Alaska.  Neil provided the following details:

Roger, VK4YB, provided more details about the crystal set of Graeme, VK2FPQ, who has a You Tube video linked below of VK3HP in cross-band QSO with Graeme.  Roger reports that there has actually been quite a bit of operating activity in VK recently, which is fantastic news!

There were no reports from the Caribbean, trans-Atlantic, or trans-African paths during this session.  UA0SNV was present but no reports have been received.

ZL1AKI was listening to WSPR from the North Island but no reports were found during the session.  Further inspection indicates that his software was reporting the old WSPR frequency of 503.9 kHz.  If he is using CAT to control his receiver it is possible that he may be listening on the wrong frequency.  If anyone knows this guy, please let him know about the new frequency.  His QRZ page does not have an email address listed.

Laurence, KL7L / WE2XPQ, reports that he made some adjustments to the 630-meter PA for a little more “kick” and seems to have had a decent session for a May night that didn’t actually achieve darkness.

Merv, K9FD/KH6 / WH2XCR, sees a return of the two-way path to WH2XGP and continues to share two-way reports with Roger, VK4YB.  John, VK2XGJ, also reported Merv three times during the session.   WG2XXM was also reported in KH6.

Jim, W5EST, is off today but should return tomorrow with more discussions.

There has been some discussion about how these reports will progress through the summer.  At the moment I intent to continue my daily reports until activity gets really slow when I will likely transition to a weekly summary and “breaking news”-style daily reports when necessary until activity picks back up again after September 1.  There are still interesting things to report from other parts of the world  and 630-meter continues to be open so I don’t think there is a reason to put up the “gone fishin'” sign just yet.  Note that I know right now that there will be no regular report during the weekend of June 10 and 11, which is Hamcom here in the DFW area where a number of knowledgeable operators will be speaking about MF and LF related topics.  Details for that can be found here.

Also upcoming is Field Day when many of us have operated our stations to transmit special Field Day messages intended as a demonstration opportunity for participating groups.  Details on last years event can be found here.  I normally don’t start working on this until after Hamcom, about two weeks before field day, but this year I have some time now and the media outlets prefer that I get them details as soon as possible.  If you are interested in participating, please let me know.  All you have to do is put some type of field day related beacon content on the air in a mode of your choosing during field day and maybe send an email to the local club about the receive-only opportunity.  Operators who are attending a field day operation might find it advantageous to develop a 5-minutes demonstration for their field day site.  I plan on driving around North Texas again this year talking to anyone who will listen in lieu of operating with a competitive group.  This will be my second year to do so and it was well received and a lot of fun last year.
