    Crew schedule now indicates SSTV activity will conclude at 18:00 UT on Monday, July 24.

  • ARISS SSTV Commemorative Activity Coming Soon (July 2017)   17 weeks 4 days ago

    It had to wait until the Progress undocking operations were finished so to be on the safe side they scheduled it for the last activity of the day before sleep (21:30 UTC).

  • ARISS SSTV Commemorative Activity Coming Soon (July 2017)   17 weeks 6 days ago

    Hi All,

    The scheduled start time coincides with the anniversary of the Apollo 11 landing of 48 years ago, which was at 20:18 GMT.

    Here is a recording of the landing you are unlikely to have come across before.

    Best listened to in the car or using earphones for optimum enjoyment.
    At 30:32 someone lights up... (could you hear that?)
    At 31:45 touchdown.


  • PD120 SSTV Test Recording to Use in Preparation for Upcoming ISS SSTV Events   17 weeks 6 days ago

    I have converted Space_Comms_PD120_SSTV_Test_Recording audio file to make it compatible to copy into Kenwood TH-D74 recording playlist which will allow to play the file and output via the 2.5 external speaker port into pc microphone input for MMSSTV/RX-SSTV to check audio levels should you want.
    Set TH-D74 Menu 980 USB Function to Mass Storage. Connect USB lead to pc and put the audio file into folder TH-D74>REC

  • REPEATER on ISS.... is active now or ? info   18 weeks 1 hour ago

    ok...just today ALL finish (crossband repeater & 2 cubesat signals ) ?


  • REPEATER on ISS.... is active now or ? info   18 weeks 16 hours ago


    The D710 crossband repeater was only on for the duration of the 2 Russian CubeSats which were scheduled for the greeting message retransmissions July 4-8 only and is now currently off. Although the CubeSats were turned off early by the crew to save battery power the crossband repeater was left on for the remainder of the test period until July 8-10:30 UTC.

    yes at the moment NO VERY ham-radio abord ISS ! only astronauts that have the ham-radio license by office :-(

  • CQ ISS REPEATER on 145.800 ?   18 weeks 1 day ago

    This is taken from the Amsat-UK site which explains.

    Two Russian satellites are planned to be activated inside the International Space Station (ISS) Russian Segment as part of a verification test from July 4-8.

    The satellites will eventually be deployed by hand from the ISS during a Russian space walk tentatively scheduled for August 17, 2017.

    The satellites Tanusha 1 and Tanusha 2 [спутники Тануша 1/2], will be downlinked at 145.800 MHz FM. Transmissions from Tanusha 1 should begin around 18:30 UT on July 4. Transmissions will cease on July 6 from 08:20 till 18:00 UT to allow the satellites to be swapped out. Tanusha 2 will then be activated beginning on July 6 around 18:00 UT and continue until July 8 at 10:30 UT.

    The satellites will broadcast greeting messages in Russian, English, Spanish and Chinese. More details will be made available on the Southwest Western State University site at

    Some stations were able to work through the crossband repeater in between the retransmissions but the crew changed the schedules and switched them off early to save battery life but the TM-D710 was left on in Crossband repeat and groundstations were able to work through 437.050 uplink and 145.800 downlink.

    These 2 new CubeSat's are the same as Tomsk-TPU-120 which did the same last year 2016 and is still aboard the ISS and will possibly be deployed by hand on the next Russian EVA.

  • PD120 SSTV Test Recording to Use in Preparation for Upcoming ISS SSTV Events   18 weeks 1 day ago

    I have Stereo Mix on both my older desktop and newer i7 laptop running windows 10 but it's not supported on all PC's.
    Here's a short video on how it works for me on the laptop.

    Contact John Brier (Space Comms) about using VB-Audio Virtual Cable and VB-CABLE Driver.

    If you have downloaded ISS-SSTV before with either MMSSTV/RX-SSTV in PD180 mode then it should work fine for faster PD120. If possible try using a recorder inline to record the SSTV transmission in case you mess up to play back afterwards.

  • PD120 SSTV Test Recording to Use in Preparation for Upcoming ISS SSTV Events   18 weeks 1 day ago

    Hi: Thanks for the guide to setting up the MMSTV program in Windows 10...I have two questions, if you don't mind! First, I cannot find "Stereo Mix" on any of my audio drop down listings...How do I get it to show up? Second, I am using the "Audio Cable" driver as both input and output, but this then disables my computer speakers and I cannot hear anything...Any way around this? I really appreciate your assistance (and patience) as I attempt to get ready for the ISS SSTV passes later this week!

    i think NO, posted at 20 July ...... 73

  • ARISS SSTV Commemorative Activity Coming Soon (July 2017)   18 weeks 3 days ago

    So there's not going to be any SSTV from the ISS this week? It's been moved to the 20th?

  • ARISS SSTV Commemorative Activity Coming Soon (July 2017)   19 weeks 16 hours 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 ?   19 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 ?   19 weeks 3 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 ?   19 weeks 3 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 ?   19 weeks 3 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 ?   19 weeks 3 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 ?   19 weeks 4 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 ?   19 weeks 4 days ago

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

  • ISS Radio Report   19 weeks 5 days ago

    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.

  • ISS Radio Report   19 weeks 5 days ago


    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.
