  • Will the ISS be on with voice for Field Day 2016 ?   14 hours 46 min ago

    ISS currently has only 1 US crewmember and is busy getting ready for some major equipment repairs. I doubt he will make it to the mic for Field Day.

  • Nice video of Tim Peake on ARISS with school !   1 week 2 days ago

    Hi Rudy,

    Yes saw this video some time ago and very informative and great views of the onboard equipment in the Columbus module including the HamTv.

    Another video of GB1SS: schools speaking to Tim Peake.
    The ten school contacts with Tim Peake on the ISS during his Principia mission have inspired thousands of young people and introduced them to amateur radio in a new and exciting way. Our new video celebrates these historic events and the range of linked activities the schools have enjoyed. https://www.youtube.com/watch?v=ByEf1xlWZyE

    TX-Factor did a great video on the last ARISS school contact with King's school Ottery St Mary Devon. Here it shows all the equipment setup used by the ARISS UK Team for the Principia Mission.
    In this special edition, we follow the progress of a Devon School in their attempt to be one of the ten lucky UK schools to link up with Tim Peake aboard the International Space Station. https://www.youtube.com/watch?v=hpUDArlvVuM

    What a great success the ARISS Principia Mission did!! Enjoyed them all.

  • ISS QSL Info   2 weeks 4 days ago

    Hi,
    An ARISS school contact programme has been organised for H.A.L. School Lucknow, India students on 12th May 2016 at 0811 Hrs UTC. In which Tim Kopra KE5UDN answered the questions of students.

    I do feel very much delighted to know whether the students alongwith the teacher who participated in programme may get the QSL card from ARISS.

    If yes, what should we do.

    If we get soft copies of the QSL cards, we can take printout of QSL cards at our end.

    Pl do reply.

  • 6 May : ARISS contact to USA school !   5 weeks 6 days ago

    The May 6, 2016 contact was successful and was the first one held in Rhode Island, USA. We had a large audience watching live: 160 people at the school, 250+ at the nearby church, and another 258 locations around the globe watching the live stream.

    You can watch the 10 minute YouTube video -- https://youtu.be/oTkq5btNW_U -- as ISS astronaut Jeff Williams makes it through all 24 student questions.

    Our small school's amateur radio station is N1ASA and we will be becoming more active as a satellite ground station.

  • Decoding software   6 weeks 1 day ago

    Hi Mike

    Amsat do a great job for satellite users but it takes a lot of effort to keep abreast of the times in modern day technology and software and the pace it's moving at.
    There's also plenty of help and information freely available via the internet from other sources now especially on here ISS Fan Club and also lots of good satellite operators with good knowledge willing to help from state-side too.
    Here is short clip screen capture i did back along of how TS-2000 hookup with Ham Radio Deluxe + Google Earth + UISS + Soundmodem APRS packet via the ISS digipeater would look like when it's running bearing in mind i was only using a 2m/70cms mobile antenna cable tied to my fence.
    https://www.youtube.com/watch?v=qm231BHWmV0
    As you can see from the clip we DON'T connect to the digipeater to send messages but just unproto packets from either of the buttons Text/data, Position, Message and MHeard

    I can also work the ISS APRS with my Kenwood THD72 handheld using 5 watts into 2m telescopic antenna like today on a low 22 deg pass. So it's really not hard at all.

    Always feel free to ask any questions up here sure others would help also.

  • Decoding software   6 weeks 1 day ago

    Thanks so much! We just had our radio club general meeting and a new ham was asking me how to transmit to the ISS. I told him it seeks you folks in England seem to be more helpful than AMSAT. A lot of beginners info on your version of amsat website. This just more or less justifies what I told him. Once again thank you so much.

    Rather than go over old ground where others have had problems i will send you some links instead to start with.

    For simple receive only of ISS APRS packet just connect a lead from from TS-2000 headphone socket to pc microphone-in socket. Tune to 145.825 FM on main radio screen and fully open the squelch so you hear static noise all the time. Run UISS and setup choose UZ7HO Soundmodem as packet engine then point the directory where it is located and tick both boxes for Auto Run and Auto Close, select LAN Setup and tick Enable, Host/IP 127.0.0.1, AGW LAN Port 8000, AGW RX Radioport 1 and same for TX radioPort. Close and reload the UISS to run-up Soundmodem. Choose Settings, Devices, Output and Imput device and PTT Port and fill in the correct details. Choose Modem settings and select Modem type ch.A VHF AX.25 1200bd and same again for Modem type ch.B. From the top menu put 1700 for both Ch A and Ch B + DCD slider nearly fully to the left and tick box to Hold pointers. You should now be able to see some signal on the waterfall. You can also try receiving from your local APRS packet frequency.

  • Decoding software   6 weeks 2 days ago

    Right now I'm not even thinking about transmitting to the space station I would just like to be able to receive it. I was up pretty much all night trying to figure things out with the software you sent a link to. The station made a couple passes and I could hear the aprs but not decode it. I also tried to see if I could some kind of reaction decoding the local aprs beacon. I have been. Setting my radio on USB as I do a lot of bpsk31 stuff I assumed. That was the the way to go but for some reason no matter what I do I can't receive or decode the signal. I can turn the volume up and down on the rig and it does effect the water fall. Any ideas??

  • Decoding software   6 weeks 2 days ago

    TS-2000 set to 145.825 FM preferably in split mode as to adjust for doppler TX/RX separately. ISS APRS packet digipeater is 145.825 MHz FM 1200 BPS uplink and downlink Path set to ARISS. It is NOT advised to try and connect to the ISS (RS0ISS-1) digipeater. Send APRS UNPROTO packets instead.
    Packet communication via ISS almost exclusively relies on using CONNECTIONLESS operation. The AX.25 protocol defines these types of packets as UI packets. An UI packet is pretty much transmitted out there for anyone and everyone to receive and copy. When stations transmit UI packets the AX.25 protocol will not be waiting for all of the handshake messages to complete – this very much simplifies the message exchange.

    If you are going to use the UISS software which most users do then this will be done automatically. UISS also comes with Soundmodem which is a pc soundcard software interface and works very well and does not require the use of the inbuilt TS-2000 TNC so make sure that it switched off. You will need to allow for doppler shift either manaul adjustment, programmed into menu or software control.

    Good luck!!

  • Decoding software   6 weeks 2 days ago

    Thank and yes it is well worth a donation. You may or may not be surprised of all the dead links for aprs software. What mode would Ai set my radio in to receive fsk,USB or fm? At this point I very happy I will hear from them. The last object in space I heard and decoded was the Dove satellite before it died.

  • Tomsk Sat to be tested 5/10-08:00 to 5/11-16:00 UTC for Univ   6 weeks 3 days ago
    Re

    Yes very strong signals on vhf via ISS 145.800 even on handhelds on low elevation passes but nothing heard on the the uhf frequency at all.
    Looking around the internet and other YouTube videos i could see others were monitoring the 437.025 FM frequency but can't see anyone else received eiher so must be very low milliwatts output power signal on that band.

  • Tomsk Sat to be tested 5/10-08:00 to 5/11-16:00 UTC for Univ   6 weeks 4 days ago

    Thanks so much! I appreciate the help. I woke up at 9:06 UTC this morning and was lucky enough to hear some chatter. Not the message loop but ARISS communicating with another HAM. I stated KE8DRY listening and was lucky enough to have the Station respond! I just got my call sign through at the end of the pass and I believe they asked me to restate my call sign, which I did not have time to do before the pass was over. It was still an amazing experience and am going to try again the next time I have a high altitude early morning pass. I am going to try again today at 3:36 UTC with another high altitude pass, hopefully this time I will get to say more than just my call sign! This has been a great experience for a new HAM. Again thanks for your help G7HCE!

  • Tomsk Sat to be tested 5/10-08:00 to 5/11-16:00 UTC for Univ   6 weeks 4 days ago

    This morning I heard the English greeting at 06:10 UTC and also worked the APRS packet digipeater in between transmissions with THD72 handheld 5 watts into 1/2 wave telescopic antenna and confirmed on ariss.net as shown in this video here. https://www.youtube.com/watch?v=bDjJ1_JaQ9w

    My antenna has got no markings on it and had for a number of years now but is exactly the same as this MFJ-1714 LongRanger Telescopic Endfed Halfwave 2 Meter HT Antenna.
    The Long Ranger 2 Meter 1/2 wave. For long range this MFJ endfed 1/2 wave is hard to beat. Outperforms a 5/8 wave on an HT because the 5/8 wave needs a ground plane. It's shorter, lighter, has more gain and places less stress on your antenna connector. When collapsed it performs like a rubber duck (0 1/2"). 40" long when extended.

    I use a SMA (wide base connector) to BNC-male connector the wider base giving more support when srewed into the radio. The antenna can be seen in the above video.

  • 9 May : ARISS contact to school in Devon - UK !   6 weeks 4 days ago

    The final ARISS school contact of the Principia Mission took place on Monday, May 9 at 0926 GMT (10:26 am BST) between The King’s School GB1OSM in Ottery St Mary, Devon and Tim Peake GB1SS on the International Space Station. I recorded and uploaded a video of the online webcast contact complete with dashbord for HamTv/Goonhilly satellite dish shown passing south over the UK on a 62 deg pass in Google Earth travelling over Europe and ending in Italy. https://www.youtube.com/watch?v=sqDscnjZgcU

    Hi Mike,
    ISS APRS packet is on 145.825 FM up/down worldwide. I also use the TS-2000 which is set in split mode RX on A-VFO (main band) and TX on B-VFO (sub band) with the second (sub) receiver turned off. This is controlled by free addition of HRD which has a satellite tracking software built in and fully compensates for doppler etc. and is available from here. http://www.iw5edi.com/software/ham-radio-deluxe-5-download-links you will either make you own leads as per user manual or buy online. I use programming and PTT interface leads from here https://radioarena.co.uk/programming-cables/kenwood/usb-cat-/-programmin....
    Free APRS packet software to work the ISS i use UISS by ON6MU download from here http://users.belgacom.net/hamradio/uissdownload.htm and it's well worth a small donation to register as there is a lot of work gone into it and also extra feature as well.

  • Tomsk Sat to be tested 5/10-08:00 to 5/11-16:00 UTC for Univ   6 weeks 4 days ago

    Hi
    Sorry to hear you not heard it yet. I use halve wave telescopic antenna mounted on Kenwood TH-D72 handheld. Try holding the radio with the antenna either horizontal or pointing towards the ground and keep moving around to find best signal during the overhead passes. I use the same antenna to work the APRS on 145.825 on 5 watts even at the lower 25 deg passes. The antenna can be seen in this video. https://www.youtube.com/watch?v=PU7tuk-ZAiE

    Tomsk-120 via ISS 145.800 is being swithced off a little earlier tomorrow morning at 10:05 UTC May 11
