Done

Hardware

  • "ezcap USB 2.0 DVB-T/DAB/FM" dongle (RTL2838U, Fitipower FC0013 tuner)
  • VK5QI HABamp
  • Raspberry Pi (+ power supply)
  • Antenna: Diamond X-50N

Software

  • Raspbian: revspace/geheim
    • IP: 10.42.43.20
    • SSH/Mosh: revspace/geheim
  • running rtl_tcp on port 1234 (default)
    • Make sure you are on a wired connection, or else latency will ruin everything

Todo

Hardware

  • Earth the antenna, to prevent static buildup
  • Moar ferrite
  • Metal box for some shielding (DIY or be lazy and get something like [1] or [2])

Software

  • Setting up a (virtual?) machine with gqrx and dl-fldigi.
    • Blokje told us we could use his machine for permanent setup
      • This requires us to move the SpaceSoundSystem towards something like a Cubieboard
        • Preferred to setup a complete NAS at the same time, this idea has been floating around for a while too
