SAQ celebrates 100 years on Alexanderson Day, June 30th, 2024.

The unique Alexanderson alternator from 1924, with the call sign SAQ, is scheduled for two transmissions on VLF 17.2 kHz CW on June 30th. Almost a hundred years ago, on December 1st, 1924, the long wave transmitter at Grimeton Radio Station, with the call sign SAQ, was put into commercial operation. Transmissions were across the Atlantic Ocean to a receiving station in Riverhead and with the replying transmitter station in Rocky Point, both on Long Island, NY, USA. The other transmitting and receiving stations in the RCA network are now long gone but SAQ has been preserved as a World Heritage Site and is still operational. The design and manufacturing of such a robust a reliable radio transmitter was a monumental achievement by the Swedish-born inventor Ernst F.W. Alexanderson.

To receive the message, you can try using a wire as long as possible connected to the microphone socket of a laptop or PC soundcard. The soundcard can then be used as a receiver allowing you to try to receive the transmissions.


ARRL Confirm Network Attack

ARRL operate the popular Logbook of the World facility used globally. In a recent update, they confirmed that on or around May 12, 2024, that they were the victim of a sophisticated network attack by a malicious international cyber group. The FBI was engaged along with third party experts to investigate. This serious incident was extensive and categorized by the FBI as unique. It compromised their network devices, servers, cloud-based systems, and PCs. The ARRL quickly established an incident response team. They now report that an extensive effort to contain and remediate the networks and restore servers is enabling staff begin the testing of applications and interfaces to ensure proper operation.


Contest Updates

If you took part in the IRTS CW field day at the start of the month, please note that the deadline for logs is next Sunday June 16th. You can submit your logs via email to contestmanager /at/ irts.ie.

Next weekend, over Saturday and Sunday the 15th and 16th of June, the RSGB 50MHz Trophy Contest takes place. It runs from 14:00 UTC on Saturday for 24 hours. Modes permitted are SSB, CW, FM, AM, JT6M, ISCAT, and FSK441. The exchange is RS and T where applicable, serial number, and a 6-character grid locator. Further information may be found at www.rsgbcc.org This coincides with the 2024 IARU Region 1 50 MHz CW/SSB Contest so plenty of activity on the 6m band can be expected next weekend.


Propagation Update

Over the past few days, the K-index which is a measure of geomagnetic field strength disturbance has been three or below. Combined with a solar flux peaking above 170, this indicates excellent HF propagation opportunities were to be had. Despite a short-lived solar storm on June 7th, NOAA's short-range geomagnetic forecast indicates it's a good time to make the most of the HF bands over the coming days.

For VHF and above, there is no significant tropospheric propagation expected over the first part of the week at least as low pressure pushes in. However, Sporadic E opportunities on the 8 and 6-meter bands have been noted and more can be expected. As we get further into the Sporadic E season, opportunities on the 2-meter band may even present themselves also.
