Det finns nu lite mer information om DATV / HamVideo från ISS. Kolla på länken nedan, där finns mycket roligt att läsa.
On board Columbus, the HamVideo transmitter is fully operational and provides permanent DATV signals, allowing ground stations to fine tune their receiving equipment. When possible, ARISS school contacts are enhanced by crew operated HamTV.
The demand for a dedicated HamTV receiver is growing. Jean-Pierre Courjaud F6DZP developed an up-to-date receiver and wrote special software for HamTV. He dubbed the receiver TuTiouner and the software Tutioune (phonetic French transcript for “You tune”).
Components for the TuTioune receiver are for sale at the BATC shop (British Amateur Television Club).The software is available for free on Jean-Pierre’s website.
Full details, including schematics, are provided on the HamTV home page:
Now and then, the HamVideo transmitter must be powered down, for several reasons. The status of the transmitter is published on the same webpage.

AMSAT-SM ARISS-koordinator Eskil SM5SRR och bloggen hamnews.se rapporterar att Sandö Räddningsgymnasium tillsammans med Minervaskolan i Ånge har blivit uttagen som en av åtta skolor i Europa som får möjlighet att få köra amatörradio till rymdstationen ARISS.
Vi håller koll på exakta datum och ger er mer information senare.

VHF-stationen på ISS har tydligen gett upp efter 16 års användning(!). Mera info från ANS:
VHF Handheld Radio Failed, ARISS Contacts Moved to Kenwood Radio on Board
the International Space Station (ISS)
The VHF handheld radio model that has been used by the ARISS program to
connect students worldwide with astronauts on board the International Space
Station (ISS) for over 16 years has given an error message and is unusable at
this time. While the ARISS technical team evaluates the best path to restore
operation from the Columbus module, ARISS contacts will be supported using the
Kenwood radio in the Russian Service Module. During this period, the packet
digipeater will be unavailable.
Switching to the 70 cm radio capability on board the Columbus module for some
operations is being coordinated. Expect further updates as we work to resolve
Amateur Radio on the International Space Station (ARISS) is a cooperative
venture of international amateur radio societies and the space agencies that
support the International Space Station (ISS). In the United States, sponsors
are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay
League (ARRL), the Center for the Advancement of Science in Space (CASIS) and
National Aeronautics and Space Administration (NASA). The primary goal of
ARISS is to promote exploration of science, technology, engineering, and
mathematics (STEM) topics by organizing scheduled contacts via amateur radio
between crew members aboard the ISS and students in classrooms or informal
education venues. With the help of experienced amateur radio volunteers, ISS
crews speak directly with large audiences in a variety of public forums.
Before and during these radio contacts, students, teachers, parents, and
communities learn about space, space technologies, and amateur radio.

Från ARRL får vi denna info:
Slow-scan television (SSTV) transmissions will be made from the International Space Station (ISS) on August 15 and 16. The MAI-75 Experiment will transmit SSTV images on 145.80 MHz over the course of a few orbits as the space station passes over Moscow. Operators in Europe and South America will have the best chances to receive images. Operators along the US East Coast may have one chance on August 16. — Thanks to Kenneth Ransom, N5VHO, ISS Ham Project Coordinator

Ny satellit från ISS. Dock stämmer ej datum enligt text:
School SSTV CubeSat to deploy from ISS
A Slow Scan TV (SSTV) CubeSat developed by students at Saint Thomas
More Cathedral School (STM) in Arlington, VA, is set to be deployed
from the International Space Station on March 7 between 8-11am EST.
STM is thought to be the first Elementary school to build their own
satellite, even Pre-Kindergarten, Kindergarten, and First Grade
students were involved in the project.
The satellite, a 1U CubeSat called STMSat-1, will transmit a SSTV
signal on 437.800 MHz.
Middle School Students took the initiative to begin exploring how to
receive data from the CubeSat and formed a Ham Radio Club. There,
they learned the basics of operating a ham radio station and explored
Slow Scan Television as an option for receiving images once the
satellite is deployed.
Be advised that the deployment could be delayed or postponed
depending on demands on the crew’s time.

Dom som har varit med ett tag i verksamheten minns säkert att det gjordes en donation från AMSAT-SM till ARISS.
Efter många år så är nu första kontakten avklarad.
Med vänlig hälsning Håkan SM7WSJ
HamTV school contact – a world first!
Thursday 11 February 2016, at 18:11 UTC, an educational ARISS radio contact took place at the Royal Masonic School for Girls, Rickmansworth,, United Kingdom. The school contact was operated by Tim Peake, KG5BVI in the frame of the Principia mission.
It was a historic event: the radio contact was enhanced with video! Tim Peake activated the Ham Video transmitter on board Columbus.
As far back as the year 2000, a proposal for an ATV system on the International Space Station was submitted to the ARISS Project Selection and Use Committee by Graham Shirville G3VZV.
November 2002, a request for amateur radio facilities on the then under construction Columbus module was submitted by Gaston Bertels, ON4WF to Mr Jörg Feustel-Büechl, Director of Manned Spaceflight and Microgravity Directorate of the European Space Agency (ESA). The request was to install wideband amateur radio antennas on the nadir of Columbus, facing the earth. With such antennas, the on board amateur radio facilities could be extended to amateur TV.
In 2003 the request was examined in detail and finally accepted. ARISS would pay for the development, manufacturing and qualification of the antennas. ESA would support the installation cost.
ARISS-Europe started a funding campaign, all donations being published on the website.
In 2004 coaxial feed throughs were installed on the port cone of Columbus. This was needed for accessing the antennas with feedlines from inside the module.
In 2005, the Royal Belgian Amateur Radio Society (UBA) signed a contract with the Wroclaw University of Technology, Poland for the develoment and manufacturing of the antennas. Whereas initial plans were for UHF, L-band and S-band antennas, only L- and S-band antennas could be ordered by lack of funding. The cost of the project was 47.000 Euro.
Early 2006 the antennas were delivered to ESA. Meanwhile main Columbus contractor EADS and subcontractor Alenia Spazio had reviewed mechanical and thermal constraints. Wroclaw University proceeded to qualifications tests (cost 3.000 Euro) and the antennas failed.
In 2007 an additional contract was signed with the Wroclaw University for the development of modified antennas. This amounted to 36.000 Euro. These antennas were accepted and installed on Columbus, October 2007.
The cost of the antennas finally amounted to 86.000 Euro and was covered by a wordwide funding campaign.
ESA supported the total installation cost of the antennas, including feed throughs and coaxial cables.
After the successful launch of Columbus and its integration into the International Space Station complex, an ARISS-Europe working group started a study for the development of an amateur television transmitter on Columbus, using one of the the S-band antennas. A debate started between the supporters of analog television (ATV) and the proponents of digital television (DATV). The working group, which met monthly per teleconference, made progress, but was stuck by the lack of funding.
As time went by, the debate on ATV versus DATV evolved at the advantage of the latter, but no funding was in sight… Then, suddenly, supported by the enthusiasm of Italian astronaut Paolo Nespoli IZ0JPA, who had performed many ARISS school contacts during his 2010-2011 expedition aboard the Space Station, at the initiative of AMSAT Italia, an Italian manufacturer, Kayser Italia, presented a project for an amateur radio DATV transmitter to ESA’s educational services. In 2012, this proposal was accepted and ESA signed a contract with Kayser Italia for the development and the manufacturing
of a DATV transmitter on S-band. This transmitter, dubbed “Ham Video, was installed on Columbus and ESA transferred the custodianship of this equipment to ARISS.
It was a long way, spanning sixteen years, from the initial proposal to the first ever HamTV school contact. A new era opens for ground station operators, interested in receiving digital amateur television from the International Space Station. A technical challenge already met by a few ground stations in Europe, USA and Australia. Long life to HamTV and success to the pioneering ground stations, world wide!
