Not quite. The tones alternate at 20 pulses per second, not
simultaneous. 1336 for 50ms, then 1800 for 50 ms, then 1633 for 50 ms,
etc.

Subject: I Was Hacked. The Spyware Used Against Me Makes Us All
Vulnerable.
Invasive hacking software sold to countries to fight terrorism is
easily abused. Researchers say my phone was hacked twice, probably by
Saudi Arabia.
By Ben Hubbard
BEIRUT, Lebanon - In Mexico, the government hacked the cellphones of
journalists and activists. Saudi Arabia has broken into the phones of
dissidents at home and abroad, sending some to prison. The ruler of
Dubai hacked the phones of his ex-wife and her lawyers.
So perhaps I should not have been surprised when I learned recently
that I, too, had been hacked.

It is not a secret that governments want security vulnerabilities in
soft and hardware. The only way to stop that is not using proprietary
software. Also, don't use cellphones at all, many of them have
backdoors to use them as a wiretap.

Subject: Empowering Our Veterans to Win Real Change
Thursday, November 11, 2021
Veterans Day statement from CWA President Chris Shelton
This Veterans Day, I proudly salute the thousands of CWA member and
retiree military veterans and their families for their service and
sacrifice. Our veterans are a source of strength for our union and the
labor movement. Even through the difficulties of the last year and a
half, our veterans have continued to step up as activists, organizers
and leaders in our union and beyond to meet the challenges we have
been faced with and ensure the progress of the working class. Since
the launch of the CWA Veterans for Social Change program almost two
years ago, CWA has been organizing a broad base of CWA activists who
are veterans and active duty service members to build power and
strengthen our union by advocating for issues that impact other
veterans and working families. In addition to advocating for
pro-worker legislation like the PRO Act, participating in community
service and advocacy, standing up for Black lives, and organizing
other veterans in their community, CWA veterans who have taken part in
this program were instrumental in securing key wins for working people
in the 2020 elections.
