Antenna Setup

SDR at FIXME

We currently have two rtl_tcp instances running at FIXME:

  • sdr1.fixme.ch:1234 (62.220.135.211:1234) (Raspberry PI, west window, MC's homemade VHF antenna)
  • foo.fixme.ch:1234 (FIXME's internal server, north window, original UHF antenna)

Service

  • The service is started with the following command is listen to the port 1234
sv start rtl-tcp
