  • ARISS SSTV Commemorative Activity Coming Soon (July 2017)   27 weeks 1 day ago

    20 July SSTV Event to Celebrate 20th Anniversary of ARISS !

    The Amateur Radio on the International Space Station (ARISS) program is planning a slow-scan television (SSTV) event starting on Thursday, July 20, and continuing for 2 days, to commemorate its 20th anniversary. Transmissions, set to get under way around 2125 UTC, will feature 12 images from past and present ARISS activities. The SSTV signal should be available nearly anywhere on the globe at some point during the event.

    “Starting with our first meeting in November 1996, our joint operations on Mir, becoming the first operational payload on ISS in November 2000, to our [more than 1,100] school contact (so far), ARISS’s accomplishments have been tremendous,” ARISS International Chair Frank Bauer, KA3HDO, said, in first announcing the SSTV event last. “We have touched the lives of many and inspired and educated countless students to pursue science, technology, engineering, and math careers.”

    The event plans to use a computer on the ISS Russian Segment, which stores images that are then transmitted to Earth using the onboard Kenwood TM-D710 transceiver, the ARISS announcement explained.

    Those receiving the images can post them at for viewing by the public.
    SSTV signals will be transmitted on 145.80 MHz using FM. The SSTV mode is expected to be PD120, with PD180 as a possible second option. Free SSTV decoder software is available on the Internet.

  • CQ ISS REPEATER on 145.800 ?   27 weeks 3 days ago

    ISS 09:40 UTC 21-deg pass over Exeter/UK packet digipeater was quiet as most stations working the crossband voice repeater over Europe whilst the Tanusha-2 CubeSat stopped transmitting the greeting messages and not heard today.

  • CQ ISS REPEATER on 145.800 ?   27 weeks 4 days ago

    Well it looks like VK4LV and myself are the only two Stations in Australia that know about the ISS Repeater because Rod and myself worked again on the pass at 20:33 EST with very good signals back from ISS so we have not heard any other Stations but I have had two Reports from ZL4JL James but James said he couldn't transmit back but I had good signal into ZL would of been nice to have a contact ??

  • CQ ISS REPEATER on 145.800 ?   27 weeks 4 days ago

    Worked VK4LV Rod again at 15:40 EST while ISS was too the west of me here I thought maybe we would hear from some VK6's but nothing was heard from WA and with ISS over ZL I also called for a contact with ZL but again nothing heard looks like the news of the Repeater back on ISS didn't get around as yet hope to make a contact before it is turned off again==we did get a report from VK4DA Bob who had his rig on scan and came across us thanks Bob hope we have a contact before it goes off and thanks for the report BOB!
    VK4EM Merv.. And VK4LV Rod you got to plus 20 that time mate thanks again !!

  • CQ ISS REPEATER on 145.800 ?   27 weeks 4 days ago

    On the pass that just went over (13:53 est) I was able to Work ROD VK4LV and the signal started at 5 x 5 and got to 5x9 plus 60db and we were able to hold the contact for around 5 min. and I was able to hold the repeater over ZL until just before the foot-print had gone ==how good is that we must pass the info onto ZL so hope to make a contact into ZL on the next good pass! MY gear here is Yaesu FT847 antenna for 70cm two 9's at 5 meters above ground and 145 is one 9 Yagi at 8 meters above ground ==hope we are going to see many more time that the repeater is turned back on Please?? VK4EM Merv one happy user of Amateur Radio From ISS THANKYOU !! IS there a QSL for a contact through the ISS Repeater ??????????

  • CQ ISS REPEATER on 145.800 ?   27 weeks 4 days ago

    I heard the SAT greeting around 7:00z (3am local). I fell asleep with the radio on and was woken by N8HM calling CQ on the next pass an hour later. No greeting heard that class at all. .

    So the switch appears to have happened sometime in that hour.

  • CQ ISS REPEATER on 145.800 ?   27 weeks 5 days ago

    I heard station calling throughout 07:20 UTC pass over UK mostly between the CubeSat transmissions. Stop/start end stop signal with just noise and no sat greeting messages on following pass 09:00 UTC.

  • CQ ISS REPEATER on 145.800 ?   27 weeks 5 days ago

    I'v heard this call in "Belle Ile" Island on my THD74.

    Hi Patrick

    Your recordings are very good and fully quietening. At 09:05 UTC all that was heard sounded like RFI breakthrough the whole pass and could faintly hear station calling through the noise but unable to make out the callsign. The 2 earlier passes were ok as the space station ascended overhead then went into loud pager like noise when moving away. I'm sure RFI is getting into the system from the ISS somewhere.

    Just after the Tanyusha 1 satellite was activated, the ISS passed over the western USA around 1919 UTC Tuesday (4 July). It was a high pass, and I was able to copy 3 of the 4 message. I recorded the messages in Chinese, Russian, and then English, missing only the Spanish message. My recording of that pass, along with smaller clips with each message and the satellite's ID ("Romeo Sierra Six Sierra") are available at:

    (look in the folder "20170704-ISS_on_145.800_MHz")

    During a pass just before 1200 UTC today, there was nothing heard from the satellite on 145.800 MHz. The packet digipeater remained operational on 145.825 MHz, even while the satellite's transmissions were being relayed on 145.800 MHz.

  • ISS crew   28 weeks 1 day ago

    Other than scheduled educational events and the unattended modes, it is up to the crew to decide if they want to use the amateur radio in their leisure time. Most prefer to spend that time taking photos or talking to friends on the phone instead. Every once in a blue moon we get a crew member that likes to play on the amateur radio.

    Will we ever have any voice contacts from the crew on ISS ?
    When ISS goes over my farm here I am sure I can see you looking back at me when we wave ?? :-)

  • ARISS SSTV Commemorative Activity Coming Soon (July 2017)   28 weeks 4 days ago

    Hello and we are looking forward to the SSTV downloads from ISS and yes Please more time because sometimes we only get part Downloads because of the pass and so far I never get to Download all the SSTV but if we had more time well that would be a big help ==I did some test with Packet last week on ISS but couldn't hit the antenna just after it passed over me and off to ZL which I can always work ISS until over ZL and I see that on FB before the Cargo Ship is there so maybe it was between me and the antenna ?? A very big thankyou for what you do for us !! :-)

  • ARISS SSTV Commemorative Activity Coming Soon (July 2017)   29 weeks 1 day ago

    In the recent past, the mode has been PD180. Guess we will find out when they start transmitting.

  • ARISS SSTV Commemorative Activity Coming Soon (July 2017)   29 weeks 2 days ago


    What SSTV mode will the ISS be using?

    Hi James,

    Received tweet from ARISS to say 'spread the word' so posted ASAP.

    Looking forward to SSTV hope it will be on for a few days.

    Your blog link don't appear to work

    SSTV on a PI:

    The signal is so loud when overhead that you can get it on any 2 meter radio set, dust of your beofeng and head outside 145.800 (wide fm)
    use mmsstv (windows) or qsstv (Linux) you dont need an interface cable use the sound card input and hold the radio (or your mobile phone) close.

    You should be able to decode the images.

    Even go out and use the phone to record the sound then send it to the PC mac laptop pi etc to decode.

    73 and have fun
