  • SSTV event now tentatively planned for January 16th   19 weeks 5 days ago

    Hi,
    According to International Space Station Calendar January 15/16, 2016 US EVA 35 – SSU Replacement (Kopra, Peake). http://spaceflight101.com/iss/iss-calendar

    Normal operations during spacewalks amateur radio is switched off for safety reasons.

    The spacewalk is scheduled to start at 12:55 GMT and last for six-and-a-half hours.

    The Expedition 46 crew begins its first full week of the New Year planning for a spacewalk scheduled for Jan. 15.
    A pair of spacewalkers will replace a failed voltage regulator to return power to one of eight power channels next Friday. Two crew members will exit the Quest airlock and work outside for 6.5 hours for the replacement work. They will also rig cables for the future installation of docking adapters that will enable commercial crew vehicles to dock at the International Space Station.

    Latest tweet from Tim Peake.!! Final suit fit check prior to Friday's EVA – feels just great! https://twitter.com/astro_timpeake?ref_src=twsrc%5Etfw

    Looks like everything points that this will be done and completed on Friday. Lets hope SSTV can go ahead as planned on Sat 16th.

  • 13 january school contact in Italy !   19 weeks 5 days ago
    re

    The contact will be broadcast on:

  • Sandringham School, St. Albans, Hertfordshire, UK   19 weeks 5 days ago

    The signal has been dropping/changing especially over the UK on overhead passes over the past couple of years compared to what they use to be. The following pass at 10:22 UTC when the handheld was switched back to packet on 145.825 at 49 deg was much better. Others got better reception on their handhelds with smaller whip/vertical antennas looking at YouTube videos compared with tracked X-Yagi's the large dish at Goonhilly for HamTv had good signals as it tracked so looks could be location orientated. Perhaps the old 4-5W Eriksson handheld is getting a bit tired now or maybe ISS antenna damaged as previously reported by Rudy -IW2BSF.!!. Some interesting observations made by M0TCE London UK on his reception of some passes 31-12-2015 shown in Active comments about overhead passes.
    Shame they don't use the 10-25W Kenwood in the Russian segment which also has better antenna for the school contacts as the QSO's on previous transmissions between SSTV is normally very strong S9 right across the footprint.
    The Principia Live Stream school video coverage of the contact was excellent as was the students..very professional.!! All credit to the leadership at the school Alan Gray (G4DJX) and staff for allowing the students to take the leading roll.
    Lets hope future contacts makes use of the HamTV as I got a Kings school, Ottery St.Mary close-by on my doorstep and would nice to get some nice video of that.

  • HamTv no active on ARISS contact on 9 january !   20 weeks 1 day ago

    Hi Everyone,

    I downloaded the full contact Fri 08-01-2016 08:47 UTC with Tim Peake-GB1SS onboard the ISS and Sandringham School-GB1SAN as a screen video capture on laptop showing the students with the Goonhilly and local satellite dishes and Google Earth live as the Space Station passed overhead with position of both my callsign G7HCE and school GB1SAN marked on the map.
    The school coverage was excellent but the ISS pass not so good making contact very difficult weak and crackling most of the pass and very strong overhead allowing about 5 questions answered.
    I also heard part of the contact on my radio Kenwood TS-2000 connected to another pc which is shown near the end of the video. On the following pass at 10:22 UTC the digipeater was switched back on and managed to upload some messages also shown at the end of the video complete with confirmed report from the ariss.net site.
    The video can be seen here and best watched in HD 1080p: https://www.youtube.com/watch?v=ChcaOemGfQ4

  • HamTv no active on ARISS contact on 9 january !   20 weeks 1 day ago

    Sorry, I didn't even think of it..

  • Sandringham School, St. Albans, Hertfordshire, UK   20 weeks 1 day ago

    I've heard astronauts on 145.800mhz on a number of occasions in the past and they've put out really strong signals which have been audible even with a handheld + a rubber duck antenna. Some years ago I worked Doug Wheelock as he was passing over the Bay of Biscay, 5-9 both ways using an FT290 and a colinear. Today I could barely copy Tim's transmissions and the school had obvious problems making and maintaining contact despite having some experienced people helping behind the scenes. The event was covered live on the BBC but it probably didn't impress the general public!

    Heard in Cork, Ireland very clear at 08:47 UTC through to 08:52 UTC

  • Sandringham School, St. Albans, Hertfordshire, UK   20 weeks 2 days ago

    Heard Tim using GB1SS talking to the students at Sandringham School. Very good signals at Cork, Ireland using VX77 and Magmount.
    It was fantastic to hear Tim with such clarity.

  • Data from Port side and South was better received than from overhead or closer   21 weeks 2 days ago

    This is very interesting. Others have observed that reception can vary based on geometry. I once received a school contact better than the telebridge station that was closer to it. Thanks for sharing.

  • Tim Peake ISS School Contacts & HamTV   21 weeks 3 days ago

    Hi All,

    Latest news posted on both Amsat UK and Principia sites.

    The first confirmed Amateur Radio school contact by UK astronaut Tim Peake GB1SS from the International Space Station (ISS) will take place on Friday, January 8, 2016 at 0847 GMT 83 deg with students at Sandringham School, St. Albans in Hertfordshire. The school will use the call sign GB1SAN.

    Tim will operating from the Columbus module and his downlink will be audible on 145.800MHz. This signal should be receivable across most of the British Isles and Europe.

    The contact will also be webcast live via the ARISS Principia Webstream https://principia.ariss.org/live and the blog at the UK Operations team for ARISS https://principia.ariss.org will be updated with details of when the web stream will start early next week.

    Unfortunately, due to the rearrangement of work tasks on the ISS following the EVA (Extra Vehicular Activity or spacewalk), this contact will probably not feature the HamVideo system as other experiments will be running in the Columbus module.

  • ARISS will be off air for a week   21 weeks 4 days ago

    The distant pass by London 540 Miles 11 degrees above Horizon was clear between 8:48 to 8:52 on the morning of December 30th 2015. The first minute from 8:47 and last minute from 8:53 the data signal lost in the squelch noise.

    The data was very clear.

    The remaining times today over London are 10:22 to 10:28, 11:59 to 12:05 almost directly over London, 13:25 to 13:41 and 15:13 to 15:18 peaking between these times.

    There was clear data signal on 145.825 but not on 145.800.

    The distance from London during the clear pass were 720 Miles above North Spain across South France and Switzerland/Italian Alps into Austria 720 miles from London. The signal clear the distance of 880 Miles along the trajectory.

    Shortest distance was 540 miles.

    Seems to have done the trick.!! Hopefully will soon get some confirmed dates/times for HamTV for early Jan 2016.

  • ARISS will be off air for a week   21 weeks 5 days ago

    Great to hear that! I tweeted @RF2Space (the group of people at NASA who manage the amateur radio equipment) last night and got a reply from them saying that they will check. Seems like they sorted it out and everything is back to normal again.

    Hi Andrew,

    At long last APRS Packet Digipeater on 145.825 is now back on the air as of last past over Exeter at 0942 UTC.

    Hello Brian,

    Can you tell us what transceiver, antenna and software you use for packet radio with ISS?
    Have soon a happy new year 2016!

  • ARISS will be off air for a week   21 weeks 6 days ago

    Hi Cor, Thank you very much, you have answered all my questions. I was also suspicious that some HAMS report "ACTIVE" in error. I think its best to copy and paste the ISS packet ref on the report as some do. Best wishes & good DX for 2016, Totsiens Brian.

  • ARISS will be off air for a week   21 weeks 6 days ago

    Hello Brian,

    Take a look at:
    http://www.findu.com/cgi-bin/ariss/index.cgi
    Scroll down to ---> Recent activity.
    At the moment I write this message I can see the last ISS packet traffic is from a long time agoo.
    AMSAT Live OSCAR Satellite Status Page website shows also info:
    http://www.amsat.org/status/
    See ISS-DATA.
    ISS crew power off the ISS amateur radio station for safety reasons because of Vehicle or EVA activities.
    http://spaceflight101.com/iss/iss-calendar/
    The ISS packet station is only active on 145.825Mhz simplex.
    The ISS UHF radio is not active anymore.
    RS0ISS-11 bbs was in the past used from the ISS Kenwood TM-D700.
    This radio is not active with packet anymore.
    Last period the ISS Erricson + packet modem where active with the RS0ISS-1 bbs callsign!
    Somethimes amateur radio operators posting that the ISS packet system is ACTIVE while it is off.
    Probably they hear packet from a packet satellite or from a local station.
    It would be much better if people post an ACTIVE report when they really see the ISS RS0ISS packet callsign on their
    own screen while the ISS is in their range!

    Can someone please confirm the ISS Digipeater RS0ISS on 145.825Mhz is now back in service, and is the RS0ISS-11 Packet Mailbox still operational. Lastly is the 437.550Mhz digipeater working. 73 Brian. ZS5SB.

    It's a fake imagen.

    That imagen never was transmite from ISS.

    It was emited from a local radio operator from Buenos Aires, Argentina.
