  • ISS Radio Report   46 weeks 6 days ago

    Thanks very much for clarifing that, I suspected that was the case but I wasn't 100% sure.

    They were both off yesterday (I'm guessing for the 6 hour space walk), they must have turned on the Ericsson when they used it for the school contact this morning and left it on but haven't gotten to the Kenwood yet.

    I only get is S4 on the Ericsson at the peak of the very best passes, but often get S9 from the Kenwood even on marginal 10-20 degree passes. On the last pass here witch was almost 70 degrees I didn't decode a single packet, similar to the original post. I don't know if it's output power or the antenna that is making the difference, but it's very noticeable.

  • ISS Radio Report   47 weeks 23 min ago

    Correct, RS0ISS is the Ericsson M-PA on the Columbus module, which does 4-5 Watts, while RS0ISS-4 is the Kenwood TM D700 system on the Support moudule, capablel of doing 5-25 Watts, this might explain why the recevied quality is so much lower.

    Not sure why the D700 is not on, it could simply be a mistake, or there could be power problems, like there were before.

  • ISS Radio Report   47 weeks 1 hour ago

    I only heard RS0ISS, not RS0ISS-4. I'm not 100% clear on this, but isn't RS0ISS-4 the Kenwood D700 and RS0ISS the Ericson, which is way less powerful?

    Hi Kenneth, Thanks for that....Not as easy to see what is happening as the old format but better than nothing.

    Hello Kaustav,

    The MAI-75 SSTV experiments were planned at 2 and 3 July in the orbits in range of Moscow.
    In Moscow is the coordinator of this SSTV event.
    So probably SSTV was turned off when the ISS was out of range of Moscow.

    Welcome Mike,

    Maybe open http://maps.google.com and verify your Latitude and Longitude for your location.
    http://www.wikihow.com/Get-Longitude-and-Latitude-from-Google-Maps

    Check the values you put in to issfanclub.com website. Did you forget the MINUS SIGN? 44.952772,-123.021181 Location for Salem Oregon USA. We are west of London England and use minus Longitude values.

    After posting this, I will check too.
    Don't have a good answer for you question, but share my links below. The "aprs tracking" app was valuable to see. Thanks for pointing it out. I had not used it before.

    I am a simple Ham Radio Operator and use http://heavens-above.com with the Tick "ALL Passes"
    to view the crossing times of the ISS from my latitude and longitude. Besides the SKY View look for the Ground Track view to see which way the ISS passes your location. You can also check other visible satellites here.

    There are many other Satellite tracking programs that others use. Your mileage may vary.

    Hello OE5KFM,

    Thanks for the youtube link!
    Now everyone can see how easy it is to receive a strong
    signal from ISS with only a 4 elements yagi.
    With a 3 or 4 elements yagi at fixed elevation at 40 degrees and a cheap TV rotator to control the azimuth its an easy job also for packet communications.

  • Help with scanner antenna..please!   48 weeks 2 days ago

    145.825 Mhz for Packet first, usually hear the packet racket when the satellite comes over your horizon about a 1000 mile radius from your location.
    My reasoning, is that since packet is normally always working you can hear when the ISS is in your area. Since Amateur Radio astronaut Commander Douglas Wheelock has left, not often that the ISS crew turns on the Amateur radio to make Voice QSOs with hams in 2013. Their schedule is tight and their free time begins at 20:00 UTC and they go to sleep at 00:00 UTC. So for Pacific Daylight Time ( California West Coast Time Summer) Listen between 12PM PDT and 5PM PDT on 145.800Mhz to hear voice transmissions. Again, check 145.825Mhz FM to check that you can hear the ISS packet activity first. then switch to 145.800. Look for time over USA when they make school contacts. Then you can hear the ISS responses. The ISS is only overhead for about 6 minutes total from horizon to horizon. Add 96 minutes (1 hour + 36 minutes) to start PASS time to have the next pass of the ISS.

    http://www.heavens-above.com will help you find ISS crossing times. Register and input your Latitude / Longitude coordinates. Select all Passes to view daytime ISS crossing. The ground Track view can give you and idea where to point your dipole antenna.

    I made a contact with 15 watts using a 1/4 wave 2 meter mag mount antenna on the roof of my car on July 21, 2010 from Dayton Oregon. Note, that a vertical will get good signal from the horizon when the signal is weak. Less signal when the satellite is directly overhead. Have fun with your Uniden scanner Mattford84
    Check for other Satellite frequencies too.
    Link for 2 Meter Antenna ideas. Use what you have for an antenna. Does not have to be fancy to listen.

    HI! According to NASA website, Luca used the HAM Radio in Columbus module.
    I receive packet on 145.825 to the same time as voice on 145.800.

  • ISS Radio Report 36579   48 weeks 4 days ago

    Could not hear the whole contact and the signal was not very high from JN44UT 30 Kms South of Piacenza.
    Does anybody know which radio Luca used, if the Kenwood or the old - I believe - collins from Columbus module?

  • Help with scanner antenna..please!   48 weeks 4 days ago

    great info thank you for the quick reply! i live in california USA

  • Help with scanner antenna..please!   48 weeks 5 days ago

    Hello Mattford84,

    Somethimes ISS crew use the Erricson handheld radio for school contacts wich has
    less power output compared to the ISS Kenwood TM-D700 wich is now used for packet on 145.825Mhz.
    Often wide band scanners does not have verry good receiver sensitivity.
    So that is why you have to connect a good antenna.
    Most wide band scanner antennes have no gain because they are wide in frequency range.

    It depends what you want to do, buy or build an antenna.
    For home made you can start with a 145Mhz dipole antenna.
    ----50cm-------0 0-----50cm-------

    Connect 50 ohm coax to the 0 0.
    The best is to put the dipole antenna on top of your house.
    Or go outside with your scanner and hold the dipole antenna free in the open air.
    But if you dont like to make an antenna you can buy a Diamond X50 antenna and put
    on top of your house.
    And if you can invest more money buy an 145Mhz yagi with rotator (a cheap TV rotor can do).
    Or build this: http://www.open-circuit.co.uk/tape.php
    Build only the antenna you dont need the receiver box cause
    you have a scanner receiver.

    Tell me what country do you life?
    If you life in Europe, tommorow is an ISS school contact with Italia:
    Often AJ9N post ARISS school contact information on the SAREX mailreflector/website:
    http://www.amsat.org/amsat/archive/sarex/48hour/threads.html
    The downlink frequency for ISS school contacts is 145.800Mhz FM/N.
