  • 8 december ARISS contact to school in France !   1 year 7 weeks ago

    On a contact like this, will you be able to hear both sides of the conversation on the downlink? Or will you only hear the astronaut speaking and not the school?

  • ISS SSTV Planned for December   1 year 7 weeks ago

    Orbitron muestra las pistas de ISS que cubren el sur de América durante estos tiempos también y sstv podría estar disponible en su área.

  • ISS SSTV Planned for December   1 year 7 weeks ago

    hola, estoy en argentina, y leo que las emisiones de sstv para esos dias son en orbitas rusas. Solo en esa zona se recibiran. O se podra por esta parte del mundo recibir sstv tambie.

  • ISS SSTV Planned for December   1 year 7 weeks ago

    The ham radio in the Russian Segment is what supports the SSTV activity and also supports voice operations. SSTV will be on 145.800.
    The radio in the Columbus module (USOS) is what supported VHF packet and Voice. The VHF radio has died and been replaced by the UHF radio and packet is now on 437.550.

  • ISS SSTV Planned for December   1 year 7 weeks ago

    Since the VHF Digipeater has recently died, will it still transmit on 145.800 MHz? Or will it move the UHF?

    Re

    Yes managed a QLS with DK1WB and was only station online. It was a lower 33 deg pass and was not expecting much so forgot to switch the satgate on for ariss.net but saved the monitor screen and screenshot of the exchange. Using the Omni I only get a narrow window of usage on 437.550, about 1 minute after AOS west of my location then it's lost overhead then not heard east of my location at all as it descends over Europe. ISS was quiet again this morning with passes being during the night hours now so won't be much activity.
    I see Amsat UK are out of stock on the ELK 2M/440L5 log periodic handheld antenna which looks like my best option at this time.

    PSAT (UO-84) packet digipeater 145.825 is back online again today so beaconed that one earlier. You should be able to test your new radio on that now. I beaconed this sat with the TH-D72 + APRSIS32 for satgate hence the -10 as wasn't sure if there were any other stations on. Haven't had any success yet with the TS-2000 + UISS and soundcard will try again over the weekend with some different settings.

    Re

    I only checked the last 2 ISS passes over last 2 days and not heard it at all with the Omni. Maybe other satgate stations are using the same and why Europe is more quiet as most activity appears to be USA. Don't really want to go down the path again of putting up more rotating beams etc. until the replacement radio is back online end of 2017 as I only just installed a new 2m ground plane antenna a couple of weeks ago..
    Heard PSAT-1 still packet beaconing this morning whilst switched off.

    Yes it was sad about MIR's demise.
    Good luck on your proposed 15 deg horizontal beam should be a good improvement with better results .

  • ISS Radio Report   1 year 10 weeks ago

    Seems I recieve better on local APRS net with the IC-2300H just now Im tracking NO-84 with my omni antenna

    When MIR was active it was more easy to get over than ISS but ofcause there was always to many stations but it
    was possible to write a mail in the mailbox in a pass, that day they have fire and power fall out I was listning it just
    disappered in a pass in the evening I saw in the TV why :-)

    I belive I must have a horisontal beam with antenna rotator maybe 15 degreeds elevation. I have worked SO-50 some
    times this summer as /P with a 3/5 el yagi on a tripond and a baofeng uv-5r it works fine :-)

    I also use soundcard as modem it works fine :-)

  • ISS Radio Report   1 year 11 weeks ago
    Re

    Sounds like a good improvement with your new Icom. NO-84 APRS has been off for a while now last time I worked it with TH-D72 HT 5 watts into 2m 5/8 wave telescopic antenna whilst walking. Not looked at the PSK31 yet.
    I tried the UISS satgate addon but prefer to use APRSISS32 with UISS as more functions and better map and works fine with both TS-2000 and TH-D72 (aprs mode)
    Never worked MIR.
    I started with the 1200 bpsk sats then mostly worked the store and forward bbs 9k6 LEO sats KITSAT KO-23/KO-25 +UO-22 + POSAT PO-28 using LL.Grace DSP-12 TNC (still got it) + KCT Tuner Tracker + Yaesu FT-847 + Yaesu G500B EL/Rotator + Tonna 144 Mhz and 430 Mhz X-Yagis RHC + Icom Masthead Preamps + PB/PG and Wisp Software running 24/7 fully automated. Those were the days.!!
    Everything today is pc soundcard and transceiver for me now.

  • ISS Radio Report   1 year 11 weeks ago

    I got the IC-2300H station today tested it at local APRS seems to listen better than the TYT TH-9800, have also been listning to NO-84 heard it 4 times with my omni antenna Diamond X520 testet the output to be 66 watt at 145.825 MHz but offcause NO-84 was APOFF :-)
    I have been testing satgate addon to UISS maybe it works :-)
    In that time I was working MIR :-)

  • ISS Radio Report   1 year 11 weeks ago
    Re

    Back in the early 90's when I use to run a fully automated satellite tracking station working all the 1k2 and 9k6 LEO Sats using Tonna X-Yagis RHC + Icom Preamps others were getting good results with Eggbeaters stateside. Hope the IC-2300H is an improvement for you.
    437.550 is not good using my Omni at this time. It will interesting to see what output power they use on Kenwood DM710GA replacement late 2017. Hope it's more than the 5 watts minimum power setting.

  • ISS Radio Report   1 year 11 weeks ago

    The eggbeater antennas works fine at 145.825 MHz but not at 437.550 MHz I use 11 mtr aircom plus cable and around 45 watt/19 watt PWR at 145.825 MHz I recieve PSAT and PCSAT when active but I never get over, last week I have ordered a Icom IC-2300H hope for a better reciever and more power :-)

  • ISS Radio Report   1 year 11 weeks ago

    Yes there are holes in satgate net on both bands. Sometimes stations can be digipeated several times before it gets routed and I have been digipeated several times by the ISS and PSAT even during a single pass and haven't been gated especially when mobile. It can depend on the gateways they are using during their setup and whether there are packet collisions when transmitting whilst receiving etc.

    Not likely to return to 145.825 until late 2017 looking at the reports with new Kenwood DM710GA. The radio needs 13.8 VDC, the ISS provides 120 VDC in the US segment and 28 VDC in the Russian segment. The power supply will allow ham radio equipment to be used anywhere on ISS.
    437.550 not ideal without some sort of pointing antenna but at least it's operational for the time being.

  • ISS Radio Report   1 year 11 weeks ago

    I also think there are big holes in the satgate net on 437.550 mhz in my area even at the 144.850 MHz east passages for my locator (JO54WX), sometimes miss stations that I see with my eggbeater :-)
    Hope it will return soon again Im weak at 437.550 MHz just testing 70 cm eggbeater not optimal at all :-(

  • ISS Radio Report   1 year 11 weeks ago
    Re

    I missed that pass and the german DK station digipeated by ISS you saw did not get picked up by any satgate stations and routed via the network unfortunately.

    Re:

    Hi Patrick

    Yes looks like the gateways and other stations have still not moved over to the UHF frequency yet as it was quiet on the last high pass over UK at 08:40 UTC and I was the only station on having missed the earlier passes which are early in mornings over here and still in darkness. http://www.ariss.net
    The TH-D74 looks to be a very nice upgrade from the TH-D72 I have here and might take the plunge near Christmas to myself. I use to work both the ISS and PSAT quite easily with TH-D72 HT into 2mtr 5/8 wave telescopic antenna whilst walking but will now have to get some sort of pointing antenna. The Elk log periodic is about the only available handheld antenna from Amsat UK this side of the pond and it appears to do a good job from what you say.

  • ISS Radio Report   1 year 11 weeks ago

    Seems like the gateways have stayed at 145.850 MHz here in Northen europe, none of the recieved stations at my place was shown 73

  • ISS Radio Report   1 year 11 weeks ago

    Hi!

    Thanks for posting that listing of packets from yesterday. It looks like more gateways are setting up on 437.550 MHz. I don't know if this means they aren't also listening to 145.825 MHz, but for now I think the UHF frequency is the place to be if these gateways can only monitor one frequency. NO-84's 145.825 MHz digipeater is rarely on, and NO-44 is a tough one to hear unless it is getting a lot of sunlight to power it up.

    I have worked two early morning passes this week, plus a pass in the past hour (midday here in Arizona). I definitely see how the trees around my house make UHF operation tough. When I am pointing away from the trees that cover the lower elevations to my north, the 437.550 MHz downlink is easy to hear with my TH-D74A HT and Elk log periodic antenna. I would expect those using omnidirectional antennas would have a harder time as you mentioned, with this change to UHF operation.

    For the pass I just worked (around 1852 UTC Saturday, 5 October - 11.52am local time in Arizona), three different gateway stations - two in Arizona, and one in California - were picking up traffic from the 437.550 MHz digipeater. The first gateway, KK6RKY in California, picked up one of my beacons about 3 minutes after my AOS. KE7JGM-6 and K8YSE-4 in Arizona covered most of the rest of the pass. Being able to look at ariss.net after ISS passes had been useful with the 145.825 MHz digipeater, and it is nice that there are some gateways that will make ariss.net just as useful with the 437.550 MHz digipeater.

    73!
