    I would purchase one just to support your initiative. It would be ideal for future SSTV events.

  • 19 august contact to Fleet Science Center in San Diego CA   5 weeks 3 days ago

    The duration of the contact is approximately 9 minutes and 30 seconds.

    The contact will be direct between NA1SS and KJ6KDZ.

    The contact should be audible over the state of California and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink.

    The contact is expected to be conducted in English.

    The Fleet Science Center connects people of all ages to the possibilities and power of science to create a better future. Established in 1973, it was the first science museum to combine interactive science exhibits with a planetarium and an IMAX Dome (OMNIMAX) theater, setting the standard that most major science museums follow today. The Fleet is home to many programs that engage girls in science, one of them is BE WiSE (Better Education for Women in Science and Engineering). BE WiSE BE WiSE engages young women in science, technology, engineering and math (STEM) learning experiences in collaboration with the region's research, industry and academic institutions. BE WiSE goals are to: stimulate young women's interest in STEM through interactions with professionals, increase participants' opportunities and knowledge of STEM fields of study, develop a community of young women (grades 7–12) engaged in science learning through out-of-school activities, and sustain interest and involvement through alumnae and ongoing participation for women in science at all levels. BE WiSE selects girls from all across San Diego County and has sustained contact with over five hundred girls over the past 14 years.

    Yes, you should be able to hear the 145.825 MHz packet signals with a handheld radio. I normally use a Kenwood TH-D74, and previously a TH-D72, to work these passes through the digipeater. You will probably want to improve the antenna on your handheld radio. Longer duckie, telescoping whip, directional antenna - something other than the normal duckie antennas that come on the radios. What radio do you have?

    Can I pick up the ISS packet radio transmissions on a hand-held? If so, what am I likely to hear?

    Thanks. Mark M6JLQ

    Bastante fuerte por el norte de Huesca, 5 7, he realizado el contacto con un walkie yaesu VX8D, 5w y una antena de 1/4 de onda. Se veía a simple vista, mi compañera ha alucinado.

    Hi Andrew

    Maybe more helpful to use UTC standard times instead of AEST GMT+10 as per or could be confusing.

  • 8 August contact to Youngsters on the Air (YOTA) !   6 weeks 4 days ago


    For those that remember when Doug Wheelock was on the microphone from the ISS in 2010, or Bill McArthur back in 2005-06, I thought those guys used NA1SS for all of there contacts around the world. Wasn't that the case over Europe? For the scheduled events, I'd guess that the non-US calls would get used more, unless it comes down to a request or an issue with third-party traffic (i.e., non-hams on the mic talking to the ISS crews).

    Other than on packet or maybe SSTV, RS0ISS is a rare one over North America. I have one voice contact with RS0ISS, done as part of an ARISS radio test one early December morning in 2013:

  • 8 August contact to Youngsters on the Air (YOTA) !   6 weeks 4 days ago

    Paolo used NA1SS when calling and signing off from GB17YOTA ARISS contact 20:14 UTC on 2nd attempt using Kenwood D710 in Russian Service Module as heard at beginning and end of this recording.

    I can understand Rudy confused and preferred if he used an European callsign instead coming from his home country Italy.
    I was very happy when he used this callsign as it's the first time for me of hearing NA1SS from the ISS which is seldom used over Europe.

    I also heard him very briefly calling NA1SS 3/4 through the first pass 18:37 UTC on Ericsson VHF when using HamTv in the Columbus Module when audio failed on the downlink.

  • 8 August contact to Youngsters on the Air (YOTA) !   6 weeks 4 days ago

    I think Paolo just misspoke when he included the "I" in the call sign. Several of the ISS call signs end in "ISS" but the US call suffix is only "SS".


  • 8 August contact to Youngsters on the Air (YOTA) !   6 weeks 5 days ago


    I think NA1SS was used since the US has a third-party traffic agreement with the UK when the UK stations are using call signs with GB special-event prefixes (except for GB3 prefixes). GB17YOTA would fall squarely within this agreement, so that is why I could see the reason for using the NA1SS call sign yesterday. If everyone who talked to NA1SS had a ham license, the US FCC would not consider that "third-party traffic", since they could have talked to NA1SS with their own call signs. I don't know if the UK's Ofcom shares the same opinion on what is or isn't considered "third-party traffic".

    strange ......Paolo used for this contact to UK the callsing american NA1ISS ! 73

    FAULT on Ericsson handy radio !

    on the pass at 20:21 UTC very strong signal (use the Kenwood radio in russian module ) on 145.800 and NO hamtv video !

  • ISS Radio Report   8 weeks 4 days ago

    Here is the latest information posted on the site. Lets hope they can find a solution to the problem soon.

    Packet Module Status
    July 25, 2017

    ARISS has received several reports stating that the packet system on ISS is down. Here is what we know and our current forward plan.

    The packet system in the Columbus module started to act up late last week, sending only a beacon. The ARISS team requested a power recycle by the crew, and with that power recycle, the packet system appears to have stop functioning completely. Note that this unit has been on-orbit for 17 years. It was launched on the STS-106 Space Shuttle Atlantis mission in September 2000 and was built, tested and certified for flight about 20 years ago.

    The ARISS team has had some extensive discussions on the way forward. We would first like to do some additional troubleshooting with the existing packet module. It will take some time (weeks) to develop troubleshooting procedures, get the procedures approved by NASA and then conduct the tests with the crew. This includes an additional power cycle. The turnaround time is much longer than usual because a new crew will soon be arriving on ISS. The current crew is focused on the new crew arrival and there will be about a one- to two-week transition after the new crew arrives. On the positive side, one aspect of our troubleshooting—a second power cycle—will occur automatically because ARISS is shut down during crew docking and turned on afterwards. However, there will be more to our troubleshooting than just the power cycle.

    We have some additional plans with alternative solutions, but those are currently being discussed and prioritized within the ARISS team. All solutions will require international ARISS team coordination, additional procedures and crew interaction. People who have carefully followed ISS operations know that crew time continues to evolve with the more extensive research that is occurring on-board. Suffice it to say, it will take longer than what it has taken in the past to work through this issue.

    The above information is to make sure that ARISS properly sets expectations on how long it will take to resolve this. At this point, expect a few months with no ARISS packet.

    As you all can see, deploying the Interoperable Radio system that is currently under development by ARISS has become even more critically important. The ARISS team is laser focused on getting that system developed and deployed. We are conducting a final design review with NASA on this system next week. But we cannot get to the finish line without your help. If you can, please consider a donation to the ARISS radio fund by clicking on the ARISS donate button on the ARISS web page ( or the AMSAT web page ( All donations, large and small are appreciated.

    On behalf of ARISS, we thank you for your sustained interest and support of our program.
