  • ISS Radio Report   38 weeks 2 days ago

    Appears inactive for the UK pass this morning - 73 Jon G4NEY

  • Kenwood TH-D72, APRS and the ISS   38 weeks 3 days ago

    After having this radio for just a few days i have had success today working RS0ISS packet digipeater 145.825 using just diamond SRH-771 whip antenna on 72 deg pass with My Position via RS0ISS shown on the screen.
    On the next pass i changed APRS TX & RX bands from A-Band (default) to A:TX B:RX and had the same problem as you not decoding packets.

    Perhaps you are not TX & RX on the same band as this would give the problem you are experiencing of not decoding packets etc. You will need to refer to the DVD manual and APRS section as shown below.

    On this transceiver you can select data band for APRS
    mode independent of the selection for Packet mode.
    Select band A or B as the data band for receiving or
    transmitting APRS packets. The default is band A. “ ”
    indicates the current data band.

    Note: In Menu 310, the selection switches among A-Band,
    B-Band, A:TX B:RX, and A:RX B:TX. Select A:TX B:RX or A:
    RX B:TX if APRS networks which use two separate frequencies
    become available in the future

    Hope this helps. David

  • ARISS will soon celebrate its 1000th educational radio contact!!   38 weeks 3 days ago

    A telebridge contact via W6SRJ with students hosted by North Dakota Space Grant Consortium (NDSGC), Grand Forks, North Dakota, USA was successful Thu 2016-03-10 19:08:55 UTC 56 deg. Astronaut Tim Kopra KE5UDN answered 19 questions for students from North Dakota and Minnesota assembled at the North Dakota Student Union ballroom with about 500 people watching.

    This was the milestone 1000th scheduled contact for the ARISS program!

    Congratulations go to the entire ARISS team on its #1000 successful amateur radio contact with ISS astronauts and cosmonauts!

  • 8 March ARISS contact by ISS to Czech !   38 weeks 4 days ago

    Hi Rudy,

    Managed to hear the start of the Q&A's on the overhead pass over Exeter UK IO80gr on HT here: https://www.youtube.com/watch?v=j42pN8WrFRE

    A bit of MIR Nostalgia for you!!..Not sure if you've seen this. BBC TV reports on Oasis Academy Brightstowe, Bristol. UK ISS-Tim Peake GB1SS contact with GB1OAB which took place on February 19, 2016.

    Tim Peake links up with British school students and we hear from some that interviewed Helen Sharman GB1MIR some 25 years ago , as well as two of them getting to talk to Tim this time round as well and ask him a couple of challenging questions. https://www.youtube.com/watch?v=OfbrTeqDvRo

    Not sure if this helps as only got this radio yesterday so not much experience yet but aprs & gps works fine for local. Hope to try it later in week for the ISS.

    Perhaps a packet or display filter setting somewhere not letting you decode.

    DISPLAY FILTER FUNCTION - This function allows you to display only the specified types of data from the station list. (APRS-5 in manual)

    Hi Alan,

    Yes I also use the amsat nasabare keps as well but always confirm current ISS position with lat/long here first http://www.ustream.tv/channel/live-iss-stream

  • Possible error in upcoming contact time? typo?   39 weeks 2 days ago

    Mostly yes, but shortly after a boost, they can lag a few hours. AMSAT gets the predicted post-boost Keps from JSC and factors them in to their list:

    http://www.amsat.org/amsat/ftp/keps/current/nasabare.txt

    Note that while most of the satellites are updated weekly, which is fine, the ISS is updated daily. More often if needed.

    Hi,
    I haven't had any problems to date with these keps as yet and appear to be quite accurate. Unless you know otherwise.?

    There are a couple of ARISS telebridge contacts with ISS passes covering the USA which you might be able to hear direct on 145.800 shown below.

    The W6SRJ station might be the 1000th ARISS contact from the ISS being the 4th upcoming contact.?..Successful ARISS contact #996 was for PS97 Harvey Austin School in the Buffalo, New York, USA.

    A telebridge contact via K6DUE with visitors at the Atlanta Science Festival, Atlanta, Georgia, USA is presently scheduled for Tue 2016-03-08 16:11:05 UTC 53 deg. The scheduled astronaut is Timothy Peake KG5BVI.

    A telebridge contact via W6SRJ with students hosted by North Dakota Space Grant Consortium (NDSGC), Grand Forks, North Dakota, USA is scheduled for Thu 2016-03-10 19:08:55 UTC 56 deg. The scheduled astronaut is Tim Kopra KE5UDN

  • 29 Feb contact ARISS with school in Germany !   39 weeks 4 days ago

    Hello to all ISS fans!

    Here is a short video containing the original audio with all questions and answers at DL0IL radio amateur station.

  • Xastir as a Satgate?   39 weeks 4 days ago

    You really only want to check the option for RF to Internet, and NOT the Internet to RF or both option.

    This way when you RX anything from the ISS via its digi it will send that via the Internet to aprs.fi or ariss.net.

    So if you think of the ISS as purley a digipeater / gateway, which sends its RSoISS call every 10-15 mins.

    If I call ISS, maybe someone in France or Germany may pick up my signal, and kindly send it to aprs igate.

    if you look at the full packet (seen on ariss.net) you will see rsoiss as the didgi in the path.
    This way you know you have got the station VIA the ISS.

    Please do let me know if you need any help, very happy to assist.

    Also look out for PSAT on 145.800 its there too.

    Best 73

    James.

    Re

    The ISS pass is NOT over Buffalo USA as it's NOT a direct contact it's over Australia and being a (radio hookup via telephone line) "telebridge" contact via VK5AZAI (53 deg from his location Australian amateur station) to PS97 Harvey Austin School in the Buffalo, New York. So you will not be able to hear the contact direct from the ISS 145.800 on your radio but from the links shown below.

    Here is small clip of Tony Hutchison VK5ZAI who is conducting the telebridge contact http://www.southgatearc.org/news/june2012/radio_amateur_vk5zai_on_tv_sho...

    Telebridge contact : ARISS has a dozen of dedicated "telebridge" ground stations covering the world. These highly performing radio stations are maintained and operated by experienced amateur radio volunteers. For a "telebridge" School Contact, the radio contact with the Space Station is established during a pass of the ISS over one of the ARISS "telebridge" stations and the signals are relayed to and from the school per telephone line.

    Here is an old 2007 list of telebridge stations. http://www.electric-web.org/telebridge-stations.pdf.pdf

    Audio from this contact will be fed into the EchoLink *AMSAT* (101377) Conference and IRLP Node 9010 Discovery Reflector. Streaming audio will be available at: https://sites.google.com/site/arissaudio/

    Hope this helps.

    Here are my Orbitron pass predictions for Melbourne 82.4 el which shows that the ISS is over south of Australia at that time. I have found that current ISS position shows different Lat/long in N2YO.com but is correct in Live ISS streaming http://www.ustream.tv/channel/live-iss-stream. Make sure your pc time is correct also and you use UTC.

    I used N2YO instead of Orbitron to double check. It matches what I have in Orbitron and does NOT appear to match the contact time. Can you tell me what your prediction shows exactly?

    I updated my keps which were older than I thought and they are now in agreement with you over Austrialia. A prediction run doesn't see any 53 degree pass over Buffalo, NY, USA that day....

  • Possible error in upcoming contact time? typo?   40 weeks 18 hours ago

    Excuse me for not understanding but it would appear that this is still the wrong side of the planet? I have tweaked the install directory of Orbitron to be read/write by all (windows by default does NOT set the program files directories writable by users, thus leading to virtualization nightmares)

  • Possible error in upcoming contact time? typo?   40 weeks 18 hours ago

    Would you recommend trusting the latest http://www.celestrak.com/NORAD/elements/amateur.txt file?

  • 29 Feb contact ARISS with school in Germany !   40 weeks 1 day ago

  • Possible error in upcoming contact time? typo?   40 weeks 1 day ago

    Orbitron shows ISS footprint covering the south of Australia at that time Tue 2016-03-01 at 16:45:18 UTC 53 deg.

    Using Windows make sure updating keps has access to the Tle folder under security options. I have found by default install on Windows 8 and above that keps have not been updated even though Orbitron says they have. These are the keps that work for me http://www.celestrak.com/NORAD/elements/amateur.txt

    The last 2 Tim Peake UK school contacts were published 3 minutes later on the ARISS site but updated on the Principia site and Orbitron also confirmed the updated times as correct.

  • Possible error in upcoming contact time? typo?   40 weeks 2 days ago

    Using the latest Keps, absolutely necessary with the ISS, I get it within range of VK5AZA at that time.

    These times align to school contact periods. Contact with the crew is unusual during these passes.
