1.   Youth on the Air campers enjoy successful ISS contact, busy with other activities

The first Youth on the Air (YOTA) camp for young radio amateurs in the Americas wrapped up
on Friday in West Chester, Ohio. Among other activities, the campers have been operating
special event station W8Y from both the National Voice of America Museum of Broadcasting
and from the camp hotel.

The earlier launch of a balloon carrying a ham radio payload was successful, and after
pinpointing where the payload landed some 3 hours away the campers were able to
retrieve the package. The balloon reached approximately 100,000 feet.

Several of the approximately two dozen campers got to ask questions of ISS crew member
Akihiko Hoshide, KE5DNI, during a Tuesday ARISS contact. Responding to a query posed by
Graham, KO4FJK, Hoshide said the most interesting things he’s seen from space included
flying through an aurora and looking down at “shooting stars” from the ISS. He also said the
ISS crew was able to view a partial lunar eclipse from space.

2. A History of Amateur Radio in Newfoundland

The Muse reports amateur or 'ham' radio has a rich history in Newfoundland
and Labrador. It gives us the ability to transmit messages over long distances
without wires or the internet. In 1901, Guglielmo Marconi received the first
transatlantic wireless radio transmission from Signal Hill. From this monumental
event sprang the Newfoundland Radio Club. This club persisted until 1959 when it
was dissolved, and the Society of Newfoundland Radio Amateurs was formed in its
place. SONRA is still active today.

The term 'amateur' does not indicate the level of expertise of the operator and instead
indicates the fact that it is illegal to use ham radio for commercial purposes or profit.
It is also essential for transmitting and receiving communications across the province
during emergencies such as natural disasters or devastating weather. During Snowmaggedon
in 2020, SONRA used amateur radio to aid in notifying emergency services when communities
on the Burin Peninsula lost the ability to communicate with each other through phone
and internet.

4. First X-Class Major Solar Flare of Solar Cycle 25 Blacks Out HF on July 3

A lot of radio amateurs may have been wondering, “Where did the bands go?” as the first
X-class solar flare in 4 years blacked out HF propagation for a time on July 3.

Many American radio amateurs reported sudden HF propagation blackouts on Saturday morning,
July 3, when solar active region 12838 produced an X1.5 major solar flare that reached
maximum intensity at 1429 UTC, the first X-class solar flare of Solar Cycle 25 and the
first since 2017,” Frank Donovan, W3LPL, said. “HF propagation blackouts are caused when
x-ray and extreme ultraviolet radiation from X-class solar flares strongly ionizes the
absorbing D-region in the Earth’s sun-facing dense lower ionosphere,” he explained.

X-class major flares are measured on an open-ended scale. The strongest one ever recorded
was an X28 flare in 2003, hundreds of times more powerful than the July 3 X1.5 solar flare.
X10-class and stronger solar flares typically have effects that last for most of a day and
affect the entire sunlit side of the Earth. Fortunately, X10-class solar flares occur only
about once every 20 years or more.
