  • PD120 SSTV Test Recording to Use in Preparation for Upcoming ISS SSTV Events   19 weeks 2 days ago

    Hi John,

    Many thanks to you for the PD120 SSTV Test upload. Just to add for Windows/MMSTV users who are not sure on the setup and unable to get the speaker sound back into the mic.!!

    From Windows right click “Speakers” icon from bottom right of taskbar.
    Click on the "Recording devices" tab.
    Right click on one of the listed items and then clicked "Show Disabled Devices".
    Select "Stereo Mix" right click "Enable".
    At this stage keep the Sound window open for adjustment.

    Run MMSSTV.
    Under “RX Mode” right click on any of the modes and select one to “PD120” and leave it in “Auto” position.
    From the dropdown menu choose “Options” then “Setup MMSSTV”
    Select “Misc” then “Sound Card In” then choose “Stereo Mix”
    From the Sound window right click “Stereo Mix” then choose “Properties”
    Select “Levels” and adjust the level to show MMSSTV vertical green bar between 1/2 to 3/4 max mark (this might need further adjustment during live ISS RX).

    Don’t forget to disable the “Stereo Mix” after making all adjustments.

  • All Events ISS 2015-2016 ARISS - SSTV -HamTV by GB1ISS !   19 weeks 3 days ago

    Hi Rudy,

    The school contacts in HamTV looks very exciting. Here is the site that is supporting Tim Peake's mission on-board the ISS and I think to watch the live school contact just select either ISS Dasboard or Live Webcast.

  • ARISS will be off air for a week   19 weeks 4 days ago

    Hi Andrew,

    No further details at this time as to when amateur radios will be back on air but hopefully soon.!!

    Full details of the unscheduled spacewalk can be seen here:

    Keep checking ISS Ham twitter site for lasts updates:

    Some very nice school contacts coming early January 2016 with major Tim Peake using callsign GB1SS will be the first ISS crew member to use the HamTV digital Amateur Radio TV (DATV) system during an Amateur Radio on the International Space Station (ARISS) contact.

    Full details can be seen here:

  • ARISS will be off air for a week   19 weeks 4 days ago

    Thanks for the update David, do we have any indication of when it may be back on the air? Is it possible for Wednesday?

  • ARISS will be off air for a week   19 weeks 4 days ago

    Unplanned EVA will result in extended time off for ISS amateur radios. Unscheduled-spacewalk-possible-on-Monday 21/Tuesday 22 Dec.

    The International Space Station’s mission managers are preparing for a likely unplanned spacewalk by Astronauts Scott Kelly and Tim Kopra no earlier than Monday, Dec. 21.
    Kelly will be designated Extravehicular Activity crew member 1 (EV1) wearing the suit bearing the red stripes, and Kopra will be Extravehicular Activity crew member 2 (EV2) wearing the suit with no stripes.

    Late Wednesday, the Mobile Transporter rail car on the station’s truss was being moved by robotic flight controllers at Mission Control, Houston, to a different worksite near the center of the truss for payload operations when it stopped moving.

    Hopefully the planned SSTV targeted for Dec 26-27 will still go ahead fingers crossed.!!

  • Received soyuz comm   20 weeks 5 hours ago

    Hi Ron,

    Must have been nice to hear the live transmissions. I watched the launch and docking of the Soyuz rocket to the ISS via Nasa Live TV and with Ustream TV/ISS tracker and did a video screen capture to show where the ISS was in relation to earth.

    The capsule apparently backed away during the automated docking sequence and had to revert to a manual dock to the ISS. Top man Yuri Malenchenko at the controls for keeping calm and making a perfect manual dock following instructions from Russian ground staff. I expect this is the part of the communications you heard with groundstation.
    The full story is shown here:

    My video screen capture of the launch, docking, hatch open and the crew entering the ISS with the crews vidio link to families on ground shown here:

  • SSTV-December 2015   20 weeks 9 hours ago

    Hi All,

    Thursday, December 17, 2015. SSTV activity being planned for late Dec. 2015.

    The ARISS Russia team is making plans to support a couple of SSTV events in the next few months. The first session is being targeted for Dec 26-27 (subject to change) to celebrate 15 years of ARISS school contacts with the ISS crew. The down link mode will be PD120 which should allow for the opportunity to receive more images in a single pass.

  • Weak signals on packet   20 weeks 6 days ago

    Hello Cor,

    well 50 watts vs 5 watts, that maybe a part of the problem :)

    A friend of mine lend me it's good old Yaesu FT290, I will listen to the ISS signals this week-end and see...

    73 from F5FIE Laurent.

    PS: at least the ROS is good, so no big issue with antenna at this point...

    In addition to this site you will generally find out when SSTV is operational on VKLOGGER

  • SSTV-December 2015   21 weeks 1 day ago

    OK! David thankyou for your reply and info ==here in Australia we are the last to know what ISS is doing and the last few times that we had SSTV from ISS it was just hours before and one time i didn't know until after the SSTV had been going for 12 hours and packet from ISS is always very good here !!
    OK i will keep looking ==Merv VK4EM

  • Weak signals on packet   21 weeks 3 days ago

    Hello Laurent,

    Better to chance your antenna system first!
    Maybe than the ISS packet signals will be much better.
    Here you can see a simple yagis system on a cheap
    rotator and antennas are at a fixed elevation.
    With this system no elevation rotator needed!
    If ISS crew call CQ (in voice) than they will hear you with a strong signal.
    I have heard that MIR was active with 50 watts power in the past.
    The ISS Erricson handheld radio works on 4 - 5 watts.
    I have heard that in the future a new Kenwood TM-D710 will go to ISS.
    Probably signals will be much better.

  • Weak signals on packet   21 weeks 3 days ago

    Hello Cor,

    and thank you for your reply.

    I understand in your reply that I have a problem with my receivers sensitivity :)

    Before changing the antenna, I will try some others (branded) receivers (I will ask a ham at my job's place).

    If things would not get better, I would consider changing my antenna, but I remember making numerous good listenings of the MIR space station with it !!

  • Weak signals on packet   21 weeks 4 days ago

    Bonjour Laurent,

    I have a 9 elements tonna cross yagi often a few seconds after ISS AOS good packet decodes till LOS.
    I also have a Diamond X5000 vertical GP antenna with good decodes when ISS is a bit closer to my QTH.
    For portable you can try a home made measure taped yagi.
    You can elevate with hand in the direction to ISS.
    Or put it with 35 degrees fixed elevation in a mast with a cheap azimuth rotator (in the past I have used a cheap channel master rotator).
    Its recommanded to use soundmodem + UISS software to receive weak ISS packet signals (do NOT use AGW!!!).
    Very importand is frequency correction because of the doppler effect you will decode more ISS packet frames.
    Many wide band scanner receivers have not a very sensitive receiver because big signals will overload the receiver.
    Scanners also have less quality filters.
    Modern transceivers like Kenwood, Icom and Yaesu have good filters and a good receiver sensitivity.
    Recommanded receiver sensitivity 0,2uV (12db sinad) or better.

  • ISS APRS off the air?   25 weeks 4 days ago

    - didn't hear it as it passed to my southeast.

  • APRS Tracking   25 weeks 6 days ago

    I will look into the tracking software.

    So are hams able to beacon that location on aprs over the air with those tracking software's data?
    I have a receive only aprs setup, just listens to 145.825 sending data heard to a private aprs server and have seen it show up once or twice in the last 3 months with an actual location beacon . That's why I was asking about it , if they have a gps connected or if it coming threw over air by other means.
    I use the private server so I can see just the stations heard by iss or other aprs sats to give me an idea of range during passes.

  • APRS Tracking   26 weeks 4 hours ago

    ISS Erricson + packet modem is not connected to GPS or other position systems.
    Better is to use good satellite trackings software to see the actual ISS position or see the
    future predictions in range of your QTH.
    Good trackings software are Satscape and Orbitron (these are free software and does not cost money).

  • ISS APRS off the air?   26 weeks 4 hours ago

    If you downloaded UISS and soundmodem, start first soundmodem and
    after that start UISS software.
    Put your transceiver at 145.825Mhz (FM/N mode).
    If ISS comes in your range you should hear the packet beacons and see
    some packet data on the soundmodem and UISS screen.
    Press with your mouse button several times on the blue position button on
    UISS software, your transceiver should start to TX these beacons.
    Let me know about your results!

  • APRS Tracking   26 weeks 6 hours ago

    Is there a way to get iss to beacon it's position as it passes over within range . Also to get my station to igate the aprs position on the map
    I see sometimes it beacons a position allot of other times nothing just beacons the other stations.

    Anyone have any idea of that or is it something with the gps of the aprs aboard the iss ?

  • HAMTV   26 weeks 18 hours ago

    I just had a low elevation pass and received several minutes of signal on 2395 Mhz. The transmitter is still happily transmitting away.
