ARDC Grant Funds FreeDV Project
To advance the state of the art in HF digital voice and to promote its use,
Amateur Radio Digital Communications (ARDC) has awarded $420,000 to the
FreeDV Project.
FreeDV is a low-bit-rate digital voice mode for HF radio. Initially
developed by David Rowe, VK5DGR, an international team of radio amateurs
are now working together on the project. FreeDV is open-source software,
released under the GNU Lesser Public License (LPGL) version 2.1. The modems
and Codec 2 speech codec used in FreeDV are also open source.
Hardware and software developers can integrate FreeDV into their projects
using the FreeDV API. To operate FreeDV, radio amateurs either run the
FreeDV GUI application on Windows, Linux and OSX machines or use the SM1000
FreeDV adaptor. Either method allows hams to use a single-sideband HF radio
to send and receive FreeDV signals. To learn more about FreeDV, go to
https://www.freedv.org.
Amateur Radio Digital Communications (ARDC) is a California-based
foundation with roots in amateur radio and the technology of internet
communication. The organization got its start by managing the AMPRNet
address space, which is reserved for licensed amateur radio operators
worldwide.
Additionally, ARDC makes grants to projects and organizations that follow
amateur radios practice and tradition of technical experimentation
in both
amateur radio and digital communication science. Such experimentation has
led to advances that benefit the general public, including the mobile phone
and wireless internet technology. ARDC envisions a world where all such
technology is available through open source hardware and software, and
where anyone has the ability to innovate upon it. To learn more about ARDC,

Radio Interference From Satellites Threatening Astronomy
Radio telescopes are facing a problem. All satellites, whatever their
function, use radio waves to transmit information to the surface of the
Earth. Just as light pollution can hide a starry night sky, radio
transmissions can swamp out the radio waves astronomers use to learn about
black holes, newly forming stars and the evolution of galaxies.
In a paper published March 3,2023, Christopher Gordon De Pree, Deputy
Electromagnetic Spectrum Manager, National Radio Astronomy Observatory;
Christopher R. Anderson, Associate Professor of Electrical Engineering at
the United States Naval Academy; and Mariya Zheleva, Assistant Professor of
Computer Science, University at Albany, State University of New York, call
for creation of a national radio dynamic zone.
This zone would be similar to existing radio quiet zones, covering a large
area with restrictions on radio transmissions nearby. Unlike a quiet zone,
the facility would be outfitted with sensitive spectrum monitors that would
allow astronomers, satellite companies and technology developers to test
receivers and transmitters together at large scales. The goal would be to
support creative and cooperative uses of the radio spectrum.
As the problem of radio pollution continues to grow, scientists, engineers
and policymakers will need to figure out how everyone can effectively share
the limited range of radio frequencies. One solution that astronomers have
been working on for the past few years is to create a facility where
astronomers and engineers can test new technologies to prevent radio
interference from blocking out the night sky.
Such a zone doesnt exist yet, but our team and many people across
the U.S.
are working to refine the concept so that radio astronomy, Earth-sensing
satellites and government and commercial wireless systems can find ways to
share the precious natural resource that is the radio spectrum.

House Subcommittee Advances Five Satellite-Related Bills
A U.S. House Energy and Commerce subcommittee unanimously approved five
space-related bills March 8, including legislation seeking to modernize
regulations for satellites in non-geostationary orbit (NGSO).
+ The Satellite and Telecommunications Streamlining Act (HR 1338) would
give the FCC defined deadlines for processing satellite license
applications. It would require the FCC to “modernize its rules to e
ncourage
operators to base their operations in the United States,” said Hous
e Energy
and Commerce Chair Cathy Rodgers (R-Wash.), “and incentivize operat
ors to
be responsible stewards of space and spectrum in a global marketplace.
+ The Secure Space Act (HR 675) would prohibit the FCC from granting
satellite licenses to foreign entities the U.S. deems a threat to national
security or domestic supply chains.
+ Launch Communications Act (HR 682) would streamline the process for
accessing certain spectrum for performing commercial spacecraft launches
and reentries.
+ Precision Agriculture Satellite Connectivity Act (HR 1339) would compel
the FCC would to review rule changes that could help promote space-based
communications for the agriculture market.
+ Advanced, Local Emergency Response Telecommunications Parity Act (HR
1353) would facilitate the use of satellites as providers of connectivity
for emergency services in areas hit by natural disasters or otherwise
lacking wireless communications.

AMSAT-INDIA Participates in Science Carnival
To celebrate National Day of India on February 28 one of the biggest
Science Carnival 2023 was organised by Gujarat state - India at prestigious
Science City Ahmedabad during 28th February to 4th March 2023.
AMSAT-INDIA was specially invited to participate in this biggest scientific
exhibition for mass awareness on Amateur Radio & Satellite Communication!
AMSAT-INDIA Regional Coordinator Rajesh Vagadia VU2EXP & team member Sakshi
Vagadia VU3EXP did huge efforts to mass promote AMSAT activities amongst
all sort of visitors which includes young kids, school-college students,
budding engineers, IT Programmers, general public, professionals from
various industries, scientists from renowned organization like ISRO, PRL,
IPR, VSSE, ISR, officers from BSF, Police, Fire dept and citizens from
every walk of life! More than 100,000 visitors were reported and grabbed
the opportunity to visit science carnival 2023 and our Science exhibition
during 5 days.
AMSAT-INDIA stall was spacious & decent sized at 3m x 3m, it was a big
attraction at the center of the Science Exhibition. With well prepared
different informative Banners on AMSAT-INDIA, Various Satellite Activities,
Amateur Radio Satellite chronology, ARISS Student outreach program, ARISS
SSTV event, Question submission for our upcoming ARISS student outreach
program etc was absolutely eye catching from a distance.
For the curious visitors we tried to highlight every aspect of our hobby
and exhibited all sorts of Radio stuff, Documents, QSL Cards, Books, Ham
License, Awards, Project articles, Tracking software, SSTV software, SDR
Software, Cube Satellite models etc to give bit idea of our hobby.
Experiencing various amateur radio gear, satellite antenna & test
instruments were highly appreciated by visiting budding engineers from a
number of colleges at AMSAT-INDIA stall. Some of the stuff we displayed
include; Dual band Arrow-II antenna, dual band Yagi, tape measure antenna,
GP, Telescopic antenna for SDR, Radios includes Icom IC-705 with LiFePO4
battery pack, Kenwood VHF base, half dozen of VHF/UHF HTs, RTL-SDR setup,
LDG ATU, NanoVNA, Morse Key, cw oscillator, Paddle, electronic keyer,
SWR/Power meter, Cable, Connectors etc. It made our task easy to explain
the use of each stuff according to the visitors' query.
We came across various types of queries like how to be a Ham, Procedure to
get license, Types of Amateur Radio satellites, operating modes, setting up
ground station, how to receive ISS SSTV images, how to establish satellite
contact etc. We made a humble attempt to answer & satisfy all of those
queries. We enjoyed a very detailed discussion with students/groups who
already know about Amateur Radio and always need to learn more on Satellite
Communication.
We also highlighted contributions of worldwide AMSAT organizations, IARU,
ARISS, RSGB, ARRL and our ARSI & GIAR. I also mark a note on an author and
my teacher Mr. Nagendra Vijay of popular Gujarati Science magazine named
'Scope' who did tremendous efforts to introduce Ham Radio in Gujarat
(India) 40 years back and still continue to create awareness via it's
leading Science magazine 'Safari', his stall was just after a row.
Our AMSAT-INDIA stall were visited by many well-wisher GIAR Ham friends
including VU2CPV Pravinbhai, VU2JGI Jagdishbhai, VU2MJP Manojbhai, VU2SPF
Bhatnagarji, VU3APY Asheshbhai, VU3VDC Vitthhalbhai, VU3GLY Priyesh, VU3WHO
Snehal etc.
It was a great experience for us to spend the whole 5 days enjoying talking
& explaining our favorite hobby Amateur Radio & Satellite Communication!
We were happy to present amateur radio as a scientific hobby &
experimenting platform for diversified fields and not just emergency
communication tools!
Lots of positive & appreciating feedback we received in the visitor
feedback book.
We are thankful to Science Carnival 2023 Organiser Dr. Vrajesh Parikh,

ISS Dodges Commercial Imaging Satellite
The International Space Station adjusted its orbit March 6 to avoid a close
approach by an imaging satellite operated by Satellogic, the latest
evidence of growing congestion in low Earth orbit.
NASA said in a March 6 blog post that the Progress MS-22 spacecraft docked
to the station fired its thrusters for a little more than six minutes,
raising the stations orbit to move out of the way of what the agen
cy
called an Earth observation satellite. According to Roscosmos, the
maneuver, lasting 375.8 seconds, changed the stations velocity by
0.7
meters per second.
NASA spokesperson Sandra Jones told SpaceNews March 7 that the spacecraft
would have approached within about 2.7 kilometers of the station without
the maneuver. She did not identify the satellite involved in the close
approach to the station other than an “Argentine earth observation
satellite launched in 2020.” Other sources said the satellite was N
uSat-17,
also called NewSat-17, one of 10 satellites launched in November 2020 by
Satellogic, headquartered in Buenos Aires.
A Satellogic spokesperson said late March 7 it received a conjunction data
message, or CDM, from the 18th Space Defense Squadron, the Space Force unit
that handles space situational awareness activities, about this close
approach.
The orbit of NewSat-17 and the other nine satellites launched in 2020 have
been gradually decaying, and are now crossing the orbital altitude of the
ISS. That is an increasing concern for ISS operations as it and other Earth
observation satellites typically operate in higher sun-synchronous orbits
that will decay if not actively deorbited at the end of the missions.
The March 6 maneuver, NASA said, will not affect upcoming spacecraft going
to and from the station. However, amateurs using the ARISS repeaters will
want to be sure to have updated Keplerian elements that take the new orbit
into account.

in the amateur community, are the inputs to the SGP4 standard mathematical
model of spacecraft orbits used by most amateur tracking programs. Weekly
updates are completely adequate for most amateur satellites. TLE bulletin
files are updated Thursday evenings around 2300 UTC, or more frequently if
new high interest satellites are launched. More information may be found at
