SDRPlayPorts

Ports of some parts of git://git.osmocom.org/rtl-sdr.git / http://sdr.osmocom.org/trac/wiki/rtl-sdr for the SDRPlay (http://www.sdrplay.com/)

Incomplete!!! Actually not working yet ... Work in progress Prototype demo:

• https://youtu.be/rDvxwpe5HT8 rtl_tcp first steps
• https://youtu.be/aYnz0Auqwho play_sdr first steps

Installation

1. SDRPlay API
   Download the SDRPlay linux api.

• x86 32/64bit: http://www.sdrplay.com/linux.html
• RaspberryPI: http://www.sdrplay.com/raspberrypi2.html

and follow the instructions.

2. Build SDRPlayPorts:

git clone https://github.com/krippendorf/SDRPlayPorts.git
cd SDRPlayPorts
mkdir build && cd build
cmake ..
make
sudo make install

Todo

• Test, refactor and enhance ;-)

Samples

• Use with OpenWebRx / Config file:

Very unstable with play_sdr so far...

I've tried the 16 bit (-x 16 switch and csdr convert_s16_f) and 8bit variant, but no luck so far, maybe you? Check for aliasing, mirrors, before reporting success ;)

# ==== DSP/RX settings ====
dsp_plugin="csdr"
fft_fps=9
fft_size=4096
samp_rate = 1024000
center_freq = 3600000
rf_gain = 35 #in dB. For an RTL-SDR, rf_gain=0 will set the tuner to auto gain mode, else it will be in manual gain mode.
ppm = 0

audio_compression="adpcm" #valid values: "adpcm", "none"
fft_compression="adpcm" #valid values: "adpcm", "none"

start_rtl_thread=True

# ==== I/Q sources (uncomment the appropriate) ====

# >> RTL-SDR via rtl_sdr

start_rtl_command="play_sdr -b 600 -s {samp_rate} -f {center_freq} -x 16 -g {rf_gain} -y 0 -".format(rf_gain=rf_gain, center_freq=center_freq, samp_rate=samp_rate, ppm=ppm)
format_conversion="csdr convert_s16_f"

• Use with Baudline
