Collective Communication Update

From tomorrow, Monday the 10th of June until July 30th, some members of
Collective Communication will be using the call sign EI 111 IAC (Irish
Air Corps). This will be in commemoration of 25 years since rescue
helicopter, call sign Rescue 111, crashed into sand dunes near Tramore
beach on July 2nd, 1999, during thick fog while returning to Waterford
airport. All crew members were lost in the accident. On June 15th, the
amateur radio station at the Shannon Aviation Museum will be using EI
111 IAC for that single day.

During Saturday and Sunday 6 and 7th of July, Collective Communication
will be on the Tramore promenade operating with the call sign EI111IAC.
The club invites all to join them, either in person, or on air as they
commemorate this very sad event. For further information on Rescue 111,

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.

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.
