RAC Ontario Sections Bulletin for February 5th, 2022

This is V__3____, Official Bulletin Station for Radio Amateurs of Canada, with this week's bulletin

NATIONAL/INTERNATIONAL NEWS

1.  Radar Altimeters and 5G Cell Networks.

The US FAA has made major progress on the issue of interference between
5G cell networks and airline altimeters.
For some models of aircraft, radio interference isn't just an annoyance; it
has the potential for deadly consequences. That was the concern of the US
Federal Aviation Administration's regarding 5G cell phone signals, which
use the same C-band spectrum as some airliners' altimeters.
Now, in a dramatic turnaround of its position, the FAA  has said that more
than three-quarters of planes have altimeters that can filter out 5G
transmissions and are in the clear. Some telecom and consumer advocates
criticized the FAA for taking too long to evaluate altimeters after the FCC
approved the cellular carriers' use of the C-band in 2020.
In 40 other countries where C-band spectrum is in use for cellular service,
there have been no reports of 5G causing trouble with altimeters.
In the US the FCC standards place a 200 MHz guard band between the
cellular carriers and the frequencies used by the altimeters.

2.  Cyberattack hits DARC Website.

The Deutscher Amateur Radio Club is reassuring hams in Germany that a cyberattack
on the website, which exploited the vulnerability of a plug-in, does not appear to have
compromised any members' data. DARC said it successfully halted the January 15th
attack and will not restore the full website to online status until it is convinced the site
is completely secured again. The DARC board reaffirmed to members that their
personal data is kept in folders that are distinct from the website and members'
passwords to the website itself are stored encrypted.
The board said it believed the attack was automated and was not launched specifically
to collect members' data. Meanwhile, an IT company has been asked to conduct a
forensic investigation.

3.    Radio amateurs prepare for all possibilities (Winter Field Day)

Members of the Warren Amateur Radio Association participated in a 24-hour
marathon to reach people across the United States and Canada as part of an
annual event to practice what to do in the case of actual emergencies.

The goal of the event is to make contact with as many people as possible over
the 24-hour time period to hone the skills of amateur radio operators, Larry Oliver
of Braceville, the association’s president, said.

“During times of severe weather and other emergencies, we’re able to communicate
with people so we do 24-hour events two times a year to practice,” he said. “We’re
connecting with other ham radio operators.”
