Satellite Memory File for IC-705

This is a memory group file over satellite frequencies for Icom IC-705 and CS-705 software. It is not complete and will be updated. Feel free to use it, change and add, make your own groups etc.

The memories are used like this:

  • Channels named with satellite name, for exemple “PO-101 Split”, are used in split mode. This channel can be used when using the IC-705 for portable operation or without an extra receiver .
  • The FM-satellites also has five split memories each with AOS-LOS frequencies – for portable operation without computer doppler tuning.
  • Channels named with satellite name and Uplink, for exemple “PO-101 Uplink”, are used only for uplink (not split). This can be used with software like SDR-Console v3 (external radio) or if you have an extra receiver.
  • Channels named with satellite name and Downlink, for exemple “RS-44 Downlink”, are used only for downlink (not split).

Import the memory file into CS-705:
Note! Be sure that you not overwrite anything in your IC-705 when cloning. Make a backup of your current settings!

  • Create a new memory group
  • Mark this new group
  • Choose File->Import->Group and choose the .csv file
  • The memories will now be imported to CS-705
  • Clone to your IC-705

As CS-705 seems to handle character set different between regions I have now created two files. If one does not work, try the other one. Comma separated is working for North America.

The files has to be downloaded as a zip file from GitHub, then use your file of interest:

If you have problems downloading the files from GitHub please contact us and the files can be sent via mail.

RT Systems Memories example

The following explanation is from Jack Spitznagel – KD4IZ, for the RT Systems software.This brief explanation assumes that the RT Systems IC-705 Programmer user knows how to import memories into the software:

  1. Before you merge these into an existing RT Systems memory set, it is first necessary to open the .CSV file in a spreadsheet (Excel or Libre Office) and edit the Channel Number and Bank names. Save the edited file as a .CSV file.
  2. Channel numbers should be set to start numbering at the first open memory row (this example: if row 77 is your first open memory row, start numbering at 77, go up to 99).
  3. Bank numbers should be changed to the first open memory Bank # in the form “##:Bank Name”. In the example, “04:Satellite” was used because Bank 0, 1, 2, and 3 already have assigned names in the memopry file that was used. Interestingly, the “Satellite” Bank Name was not recorded which requires some easy editing of the new file.
  4. Save your RT Systems memory file to a NEW FILENAME so you don’t lose your settings. Users may want to edit the arrangement once the data is imported into the RT Systems IC-705 Programmer.

Users may want to edit the arrangement once the data is imported into the RT Systems IC-705 Programmer.

IARU Coordinates Frequencies for Six Satellites in October

During the month of October the IARU coordinated frequencies for six
upcoming Amateur Radio satellites:

  • OreSat0 (Portland State Aerospace Society at Portland State
    University is a 1U CubeSat. The mission is to provide flight heritage
    to the “OreSat bus”, an open source card-cage based system that is
    ideally suited for education CubeSat projects involving
    interdisciplinary teams of students. Downlinks on UHF using CW
    beacon, 9k6 G3RUH AX25/APRS packet beacon and a 96k GMSK
    engineering downlink. Also downlink on S Band using amateur 802.11b
    DPSK with 11M chip/sec spread and 1 Mbps data rate for bulk mission
    data. Downlinks on 436.500 MHz and 2425.00 MHz have been
    coordinated. Planning a launch with Momentus Space from Cape
    Canaveral in February 2021 into a 450 km polar orbit. More info at:
    http://oresat.org/ and https://github.com/oresat.
  • TartanArtibeus-1 (Carnegie Mellon University) is a 1P PocketQube.
    The
    Amateur Radio community globally will be provided with a delay
    ping-back service, allowing Amateurs to send messages, with replies
    from the satellite transmitted later. A UHF downlink using 3kbps FSK
    compatible with RadioHead library. A downlink on 437.170 MHz has
    been coordinated. Planning a SpaceX launch from KSC in December 2020
    into a 550km SSO.
  • SATLLA-2 (Ariel University) is a 2P picosat that will take
    low-resolution photos and will broadcast the photos over the Amateur
    Radio with its position in orbit and data from its sensors. UHF and S
    Band downlinks using LORA from 476bps to 9k6 bps. Downlinks on
    437.250 MHz and 2401.000 MHz have been coordinated.Planning a SpaceX
    launch into a 410 km 52 degree orbit in December 2020.
  • CSIROSat-1 (University of South Australia & CSIRO) is a 3U CubeSat
    mission that will perform hyperspectral infrared imaging of the earth
    for scientific research purposes. An experimental two-way link for
    Amateur Radio operators to exchange short messages through a
    ‘ping-pong’ arrangement of data exchange is among the several
    communications experiments. Proposing a 9k6 FSK downlink. A downlink
    on 437.315 MHz has been coordinated. Planning a launch from Cape
    Canaveral in March 2021 into an ISS orbit.
  • PyCubed-1 (Carnegie Mellon University) is a 1P PocketQube that will
    test a novel 3-axis attitude control system based on magnetic torque
    coils. In addition, it will test new low- power LoRa radios in
    low-Earth orbit which will be of interest to many other Amateur Radio
    small satellite operators. Proposing a 3kbps UHF downlink. A downlink
    on 437.290 MHz has been coordinated. Packets are standard LoRa format
    and are compatible with the RadioHead library. Planning a SpaceX
    launch from KSC into a 550 km SSO in December 2020.
  • Grizu-263A (Zonguldak Bülent Ecevit University) is a pocketcube
    satellite with a digipeater mode that will allow forwarding of
    received messages back to earth to support communication between
    Amateur Radio operators. Proposing a UHF downlink using 4k8 FSK. A
    downlink on 437.190 MHz has been coordinated. Planning a SpaceX
    launch from Vandenberg into a 500 600 km SSO in December 2020.

Info från AMSAT-SM styrgrupp

(Swedish only)
Hej, lite info från AMSAT-SM styrgrupp. Egentligen finns inte så mycket att rapportera, med tanke på Covid-19 har vi inga större planer på gång vad gäller fysiska träffar.

  • Vi har fortsatt att ge råd runt KTHs nya markstation för satelliten MIST. Vi hoppas att de snart är klara med stationen och då förhoppningsvis kan vi publicera lite bilder.
  • Det finns ett intresse runt föredrag om amatörradiosatelliter, jag (Lars SM0TGU) har ett antal förfrågningar vilandes pga. Covid-19. Jag är redo att åka ut när det är tillåtet igen med fysiska möten!
  • Vi fortsätter ge information och skriva artiklar på vår hemsida och Twitter. Jag upplever att intresset runt satelliter fortsatt är stort.
    AMSAT-SM är ett välkänt varumärke i denna lilla begränsade del av amatörradio-hobbyn.
  • Håkan tror jag håller igång HF-nätet så ofta som möjligt.

73 Lars SM0TGU
