  • 27 september the HamTV on Space Station ISS return on-air !   7 weeks 5 days ago

    more info of HamTV system on the ISS :

    HamTv data:

    Downlink frequencies: 2.422 GHz, 2.437 GHz

    Contingency frequencies : 2.369 GHz, 2.395 GHz

    DVB-S like signal (without PMT tables)

    Symbol rates: 1.3 Ms/s, 2.0 Ms/s
    FEC : ½
    Video PID = 256
    Audio PID = 257

    Antennas: ARISS 41 and ARISS 43 patch antennas on the nadir of Columbus

    RF radiated power : approximately 10 W EIRP

    Ham Video operates with a Canon XF-305 camera.

    The transmitter is installed in the Columbus module and can transmit DVB-S signals on 2369 MHz, 2395 MHz, 2422 MHz or 2437 MHz at either 1.3 Msps or 2.3 Msps with 10 watts of RF output.

    The main mission of HamTV is to perform contacts between the astronauts on the ISS and school students, not only by voice as now, but also by unidirectional video from the ISS to the ground.

    In addition to school contacts the equipment is capable of transmitting other pre-recorded video up to 24 hours a day to allow ground stations tuning.

    HamVideo is the name of the onboard DATV S-band transmitter. HamTV is the name of the complete system, comprising DATV downlink and VHF voice uplink.

    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   13 weeks 5 days ago
    re

    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.

    Hi!

    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?

    Hello.

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

    Thanks. Mark M6JLQ

  • ISS Radio Report   14 weeks 3 days ago

    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 ariss.net or could be confusing.

  • 8 August contact to Youngsters on the Air (YOTA) !   14 weeks 5 days ago

    Hi!

    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) !   14 weeks 6 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.
