  2. Install Armbian on your Dreamcatcher board
  3. Once it boots, update and upgrade in terminal (you can copy the command line commands below into terminal):

    sudo apt-get update
    sudo apt-get upgrade
  4. Install necessary dependencies:

    sudo apt-get install build-essential cmake libfftw3-dev libusb-1.0-0-dev curl libcurl4-gnutls-dev ntp
  5. Install rtlsdr library (as described on http://osmocom.org/projects/sdr/wiki/rtl-sdr ):

    cd rtl-sdr/
    mkdir build

  7. Running wsprd:

    ./rtlsdr_wsprd -f 14095600 -c [callsign] -l [grid] -d 2 -S

Help copy pasted:

rtlsdr_wsprd, a simple WSPR daemon for RTL receivers

Use:    rtlsdr_wsprd -f frequency -c callsign -l locator [options]

        -f dial frequency [(,k,M) Hz], check http://wsprnet.org/ for freq.

        -c your callsign (12 chars max)

        -l your locator grid (6 chars max)

Receiver extra options:

        -g gain [0-49] (default: 29)

        -a auto gain (default: off)

        -o frequency offset (default: 0)

        -p crystal correction factor (ppm) (default: 0)

        -u upconverter (default: 0, example: 125M)

        -d direct dampling [0,1,2] (default: 0, 1 for I input, 2 for Q input)

Decoder extra options:

        -H do not use (or update) the hash table

        -Q quick mode, doesn't dig deep for weak signals

        -S single pass mode, no subtraction (same as original wsprd)
