From the BBC Media Centre (press release):
BBC World Service announces Emergency Radio Service for Gaza
It will provide listeners in Gaza with the latest information
and developments as well as safety advice on where to access
shelZtood and water supplies
November 1, 2023
BBC News Arabic has announced an Emergency Radio Service for Gaza
in response to the conflict in the region.
The emergency service – Gaza Daily – will broadcast vital news
daily to the people of Gaza during this time of urgent need.
It will provide listeners in Gaza with the latest information and
developments as well as safety advice on where to access shelter,
food and water supplies.
Produced in Cairo and London and broadcast on medium wave, the
service will initially run one programme a day at 1500 GMT from
Friday 3 November. A second daily update will be broadcast at
0500 GMT from Friday 10 November.
The BBC World Service has a history of responding to emergency
situations globally. Most recently, in May 2023 during the
conflict in Sudan BBC News Arabic began an emergency radio
service. In February 2022, the BBC News Ukraine service began
extended TV bulletins following the invasion of the country. The
BBC also previously launched a service for Gaza in 2014 following
a summer of conflict.
Liliane Landor, Director, BBC World Service, says: "BBC News
Arabic are extremely well-placed to offer this vital service for
the people of Gaza at a time of greatest need. Their expertise
and specialist knowledge of the region alongside the BBC's
reputation as the most trusted news provider, means we can reach
civilians in Gaza with the information they need."
Note to editors: The Gaza service will be broadcast on MW 639kHz
for morning and evening episodes.

We Shortwave Radiogram listeners know that radio -- medium wave,
shortwave or FM -- can be used to transmit text and images as
well as the usual voice content. To demonstrate our ability to
transmit Arabic text, this excerpt of a recent BBC Arabic news
story about power failures in Egypt ...
بدأت الانقطاعات المتكررة للكهرباء في مصر تزداد موخراً رغم تصريحات
حكومية سابقة أكدت أن وزارة الكهرباء والطاقة المتجددة المصرية
ستتوقف عن العمل باستراتيجية تخفيف الأحمال بحلول منتصف شهر أكتوبر/
تشرين الأول، وذلك مع بدء انخفاض درجات الحرارة.

From New Atlas:
NASA testing two-way, high-speed laser space communication system
By Michael Irving
October 29, 2023
NASA will soon demonstrate a laser-based communication system
between ground facilities and the International Space Station
(ISS). The technology will boost data transmission speeds by 10
to 100 times the current capabilities, potentially paving the way
for a new standard in deep space comms.
Radio has been the standard communication tech for spacecraft
since the very beginning, but it's showing its age as the amount
of data being beamed to and from space surges. Data can be
encoded far more densely into light than radio waves, so optical
systems are being explored for high-speed connections between
spacecraft and facilities on the ground.
NASA is planning a major step towards that goal, with the launch
and test of its first two-way, end-to-end laser communications
system. It's known as the Integrated Laser Communications Relay
Demonstration Low Earth Orbit User Modem and Amplifier Terminal
(ILLUMA-T), which is due to launch in November aboard SpaceX's
Dragon spacecraft.
ILLUMA-T, which consists of a telescope and a two-axis gimbal,
will be installed on the exterior of the space station. From
there, it will track and communicate with the Laser
Communications Relay Demonstration (LCRD) satellite, which NASA
launched in December 2021. The LCRD, parked in geosynchronous
orbit, will then beam the signals down to ground stations in
California and Hawaii. After it arrives on the ground, the data
will be forwarded on to the ILLUMA-T team at Goddard Space Flight
Center to check that it's still accurate and high quality at
those speeds.
The data will be relayed at speeds of 1.2 gigabits per second,
which is up to 100 times faster than the old radio communications
and twice as fast as previous laser-based demonstrations.
However, other teams have managed even faster data transmission
speeds using lasers, including the TBIRD satellite which
transmitted data at 100 Gbps in a test last year.
If the experiment is a success, NASA hopes that laser
communication could become a regular part of operations not only
on the ISS, but for the Near Space Network – which would cover
satellites orbiting Earth and the Moon – and the Deep Space
Network, which communicates with spacecraft exploring farther
away in the solar system.
