Bonjour,

Pour information.. 27/08/2014

Transmission radioamateur depuis la station spatiale ISS par le cosmonaute D. P.

"Dmitry Pashkov R4UAB informe qu'il y aura des séquences SSTV utilisant l'indicatif RS0ISS sur 145.800 MHz en FM, mercredi 27 août. La réception utilise MMSSTV, le mode n'est pas précisé, il est conseillé se mettre en décodage automatique de mode."

SSTV?

Logiciel de décodage (démodulation) SSTV :

http://hamsoft.ca/pages/mmsstv.php

Pour utiliser les logiciels radioamateurs (RA), vous n"avez pas besoin d"une licence RA pour ne faire uniquement que de la réception (décodage de donnée)

Bonne réception et décodage.

Passages exploitables en heure TU: 10h47 - 12h23 - 14h00 - 15h37 - 17h14

Heure local à suivre : 16H00, 17H37 et 19H14.

J"ai malheureusement râté les deux premiers passages, j"espère que le cosmonaute n"a pas déjà transmis en SSTV ou bien va pouvoir encore le faire prochainement..

ISS Slow Scan TV on August 27

Dmitry Pashkov R4UAB reports that the Slow Scan Television (SSTV)
experiment MAI-75 on the International Space Station (ISS) may be
active on Wednesday, August 27 using the call sign RS0ISS on 145.800
MHz FM.

A Google English translation of the work plan says “On Gagarin from
Space”. Open gear with ISS RS by amateur radio link to ground receiving stations amateurs around the world images of photographs devoted to the life and work of the first cosmonaut Yuri Gagarin.

It is unclear how long the SSTV transmissions will continue for but the plan shows the Kenwood TM D-700 transceiver being used for a school contact in the Ruzaevo district on Saturday, August 30.

All you need to do to receive the SSTV pictures from the space station is to connect the audio output of a scanner or amateur rig via a simple interface to the soundcard on a Windows PC or an Apple iOS device, and tune in to 145.800 MHz FM. You can even receive pictures by holding an iPhone next to the radio’s loudspeaker.

The ISS puts out a strong signal on 145.800 MHz FM and a 2m handheld
with a 1/4 wave antenna will be enough to receive it. The FM transmission uses 5 kHz deviation which is standard in much of the
world.

Many FM rigs in the UK can be switched been wide and narrow deviation FM filters so select the wider deviation. Handhelds all seem to have a single wide filter fitted as standard.

On Windows PC’s the free application MMSSTV can be used to decode
the signal, on Apple iOS devices you can use the SSTV app. The ISS Fan Club website will show you when the space station is in range.

Bijour,

J"était à l"écoute jeudi dernier (comme des dizaines de radioécouteurs et de radioamateurs en Europe) au passage de 16H00, il y avait bien une porteuse, mais malheureusement pas de signaux TV.. En fait, la raison est un soucis technique au niveau de la station radioamateur à bord de l"ISS.

Il n"y a pas eu d"émission TV à cause d"un cordon défectueux tout simplement (et bien entendu, il n"y en avait pas un autre en réserve..).

ça sera donc pour une prochaine fois..

SSTV transmissions from the International Space Station

The Russian ARISS team members plan to activate SSTV from the ISS on Thursday December 18 and Saturday December 20, 2014.

Expected SSTV mode will be PD180 on 145.800 MHz with 3 minute off periods between transmissions. A total of 12 different photos will be sent during the operational period.

Start time would be around 14:20 UTC on December 18 and 12:40 UTC on December 20. The transmissions should terminate around 21:30 UTC each day.

(Exemples : http://www.dk3wn.info/p/?m=20140906 )

Space X 5 will be launching this week and delays in the launch could adjust SSTV operational times.

Hé voilà le travail..

Bon, pas facile du tout depuis Dole, avec un WX pourri..

Réception avec mon scanner Icom R20 et son antenne télescopique au passage de 18H30. J"espère faire un peu mieux demain ou samedi.



Bien entendu, l"enregistrement audio sera disponible dans l"avenir sur l"ordinateur du groupe astronautique, comme une vingtaine d"autres..
