Configuration 4 was used:
* ARISS antenna 43
* Frequency 2395 MHz
* Symbol rate 2.0 MS/s

Ground stations G4KLB, F6DZP, IK1SLD and KI (Livorno) received the signals and streamed the video over the BATC server. The DATV signal was received for about 6 minutes.

Commander Wakata congratulated ARISS for this achievement and answered a series of questions, prepared in the manner of a school contact. He also proceeded to a microgravity experiment.

Congratulations to the Ham Video team for this outstanding performance.

Next step should be a video enhanced ARISS school contact. We will keep you informed on any progress.

The Ham Video transmitter has downlink frequencies of 2.369, 2.395, 2.422 and 2.437 GHz in a DVB-S type format (symbol rates of 1.3 Ms/s and 2.0 Ms/s). The two patch antennas, ARISS 41 and ARISS 43, are located on the nadir of the Columbus module. The Ham Video transmitter puts out approximately 10 W EIRP. The camera is a Canon XF-305.

ISS astronaut Koichi Wakata KC5ZTA will operate using the call sign OR4ISS. Ground stations F6DZP and IK1SLD will receive the signals and stream the video over the BATC server. The video is expected to be received during 5 minutes.

This will mark the end of the Blank Transmissions.

We thank the operators who filed reception reports of blank transmissions. Your  participation to the Ham Video testing campaign has been invaluable.

No decision has been taken yet on the future use of Ham Video. We will keep you informed on any progress.

President’s greetings message sent from space

A greetings message from the President of the Republic of Lithuania Dalia Grybauskaitė has been transmitted by the amateur radio satellite LituanicaSAT-1. She is believed to be the first President of any nation to have a greetings message sent from space since President Eisenhower in 1958.

In 2013 the President of the Republic of Lithuania, Dalia Grybauskaitė visited the Science Communication and Information Center (SCIC) at Vilnius University. There she saw the amateur radio CubeSat LituanicaSAT-1. Using a handheld radio and the call sign LY5N she transmitted through the satellite’s FM voice transponder.

Her words “Greetings to all Lithuanians around the world” were recorded on a memory chip in the satellite and the message was successfully transmitted from space on March 22, 2014 at 04:17:38 UT.

LituanicaSAT-1 was launched to the International Space Station (ISS) on January 9, 2014 and was deployed with other amateur radio satellites on February 28.

The tiny satellite is just 10x10x10 cm with a mass of 1.090 kg yet it has a VGA camera and a 145/435 MHz FM voice transponder, designed and built by Lithuanian radio amateurs.

The prototype of the FM repeater has been operating in the home of its designer Žilvinas Batisa LY3H in Elektrėnai, Lithuania. Further information at http://ly3h.epalete.com/?p=303

On Sunday, March 23, Ham Video will start transmitting in configuration 4, i.e. 2395 MHz and 2.0 Ms/s.

Due to SpaceX docking and related operations, Ham Video blank transmissions will come to an end March 31.

The last commissioning step will be planned in April or in May 2014. We will keep you informed on the precise date and time.

Reports on reception of blank transmissions are very welcome. Reports can be filed via this webpage: http://www.spaceflightsoftware.com/ARISS_FSTV/submit.php

Participants using the Tutioune receiving software can record as well as stream detailed parameters of the received signal. Please see: http://www.vivadatv.org/

On Thursday, March 20, three ground stations tested chained reception of Ham Video signals. Jean Pierre Courjaud reported on this experiment on his website. The report is available at
