  • how to sked voice contact ?   18 weeks 12 hours ago

    All depends on the interest of ISS crewmembers if they want to do
    random contacts.
    There is no guarentee.
    Put your transceiver in the squelch at 145.800Mhz (with -600khz shift) and
    wait till you hear a voice in these 6 months :-)
    Yes it can be possible that Samantha use the callsign IR0ISS.

    Keep following the Oscar satellite status ISS reports:
    Look at ISS-FM

    And keep following ifc voice reports:

  • how to sked voice contact ?   18 weeks 1 day ago

    Hello IW2GJV,

    In December 2012 I have asked Samantha Cristoforetti (via twitter!) if she would like to do random contacts via amateur radio during her mission.
    She replied: I thinks so

    Probably the first month(s) she will be verry busy with her work duties and exploring the space station.
    If you have twitter you can send her a message and invite her to come on amateur radio.

    Crew timelines work scedule:
    Times are in UTC.
    Presleep time is the "free" time after work and before sleep.
    During the weekend crew has less work duties.

  • ISS Radio Report   18 weeks 2 days ago

    They turn the radio off for Progress, Soyuz and ATV docking and undocking. The new expedition 42 crew just arrived on a Soyuz on Sunday (Nov 23).

  • how to sked voice contact ?   18 weeks 2 days ago


    For Europe, you should be able to RX on 145.800 and TX on 145.200 (standard -600 kHz repeater shift) for ISS voice contacts.

    Although Samantha Cristoforetti (new Italian ISS crewmember) has her own amateur call IZ0UDF that she might use in orbit, she may use one of the other ISS calls. For scheduled contacts, she may use one of the ISS calls to comply with third-party traffic restrictions.

    The ISS workday normally follows the UTC clock, not Houston (NASA mission control) or Moscow (Russian mission control) time. This may change from time to time due to the tasks they are working on, or for docking/undocking procedures.

    Crewmembers, generally, can use the radio gear on their (limited) free time. We won't get a chance to schedule a contact with the ISS, unless it is for something related to a school or other special event. We are sometimes alerted to the possibility of a crewmember being on the radio, like we saw in June when Reid Wiseman was on the air over North America for the ARRL Field Day. If Samantha wants to use the radio, you may hear her over Italy during her time on the station.

    Good luck, and 73!

  • Have you seen the ISS with your naked eyes??   21 weeks 6 days ago

    yesterday 29th October at 19:09PM IST(13:39GMT) I saw ISS through naked eyes. It was passing over my city (Pune, India). A very bright star like object but was moving from North-West to South-East. Such a glorious experience as from months I was awaiting to have a glimpse of it. Yesterday got a clear cloud-fee sky.

  • Contacting ISS   23 weeks 3 days ago

    Hello Malcolm,

    For a personal contact it is not true that you can book a time to make a contact with the ISS crew.
    Only if you want to apply for an official ARISS school contact.
    Random contacts depends on the interest of ISS crew members.
    In the past some ISS crew members liked amateur radio and some made a lot random contacts.
    Current ISS crew is not much voice active.
    Reid Wiseman made random contacts during the USA field day event.
    Alexander Gerst made a few sceduled contacts with German hams he knows.
    I think you have to wait a while for next crew so keep following voice status reports.
    But you can always join packet/aprs via the ISS.

  • First ISS Contact from Ghana (9G2AA)   24 weeks 2 days ago

    Hello 9G2AA,

    Here is a youtube video showing receiving a ISS SSTV picture!
    At the end you hear voice conversation from Richard Garriott (space tourist aboard the ISS in 2008).

  • First ISS Contact from Ghana (9G2AA)   24 weeks 2 days ago

    I certainly received it during the ISS pass over Ghana and on their designated frequency. I am using a USRP N210 radio and SodaRadio as my hardware and software setup. I guess the frequency might be a little offset. However, can I receive NOAA satellite imagies on an amateur (ISS) frequency??

    Thank you.

  • First ISS Contact from Ghana (9G2AA)   24 weeks 6 days ago

    The sound you are hearing is coded images coming from a weather satellite. It might be one of the NOAA Sats. If you have the correct decoding software, you can receive the images that the sat is taking of earth.

  • First ISS Contact from Ghana (9G2AA)   25 weeks 2 days ago

    Not sure what you were recording but that is not like any signal I have heard from ISS amateur radio system. The packet system has much shorter bursts and is on 145.825. Voice or SSTV would be on 145.800.

  • Voice Contact?   25 weeks 3 days ago

    Hello Donevin Kelly,

    Current ISS crew is not much voice active with random contacts.
    Reid Wiseman has made only few random contacts on USA and
    Alexander Gerst (DP0ISS) has only made (sceduled) contacts with
    German hams he know.
    But you can make APRS/packet contacts via the ISS packet system.
    RS0ISS aprs/packet is 24 hours per day active on 145.825Mhz.
    With AGW and UISS soundcard software you can work via the
    ISS digipeater system.
    Also good packet software is soundmodem:
    You can follow the ISS aprs/packet tracking via this website:

  • Xastir as a Satgate?   26 weeks 5 days ago

    Hi, everything is outdated. Few apps have been maintained. The UISS and the soundmodem do work. The AGW packet app works but needs set up correctly. I use both as I have a TNC also.

    There seems to be a packet repeater working where the ISS only repeats what it hears. The ISS sends out its name in APRS MESSAGE. BUT I never seen it leave a position on any of my igate/APRS MAPS. YOU CAN SEE IT ON map along with the stations it hears. I am new at this and don't know if I am correct or not but this is from my observations.
