This worked for me....on ubuntu 16.04 xenial

[patelkes]

Hi krippendorf

I was able to use this on my ubuntu 16.04 xenial on linux pc(nuc) as a openwebrx signal source...

I used convert s16 and -b 1546 -s 2048 for VHF feqvency using sdrplay api 2.09 it started working flowlessly. Thank you mate..At this stage it only use First A antenna.

Can you add options to make it work with antenna B and Hi-Z?

You are very near to real working solution. Even you are not programmer, you can do it as you have a attitude to make it work....

Best Regards

Patelkes

@patelkes Could you please post these lines from your config_webrx.py configuration file? Thank you!

My current problem is: $ play_sdr -b 1536 -s 2048 -f 3600000 -x 16 -g 35 -y 0 -| nmux --bufsize 512000 --bufcnt 98 --port 4951 --address 127.0.0.1 [openwebrx-main] Waiting for I/Q server to start... Failed to start SDRplay RSP device.

NOTE: you can find additional information about configuring OpenWebRX in

the Wiki:

https://github.com/simonyiszk/openwebrx/wiki

==== Server settings ====

web_port=8073 server_hostname="localhost" # If this contains an incorrect value, the web UI may freeze on load (it can't open websocket) max_clients=4

==== Web GUI configuration ====

==== sdr.hu listing ====

If you want your ham receiver to be listed publicly on sdr.hu, then take

the following steps:

1. Register at: http://sdr.hu/register

2. You will get an unique key by email. Copy it and paste here:

sdrhu_key = ""

3. Set this setting to True to enable listing:

sdrhu_public_listing = False

==== DSP/RX settings ====

dsp_plugin="csdr" fft_fps=9 fft_size=4096 #Should be power of 2 fft_voverlap_factor=0.3 #If fft_voverlap_factor is above 0, multiple FFTs will be used for creating a line on the diagram.

samp_rate = 2048000 center_freq = 147000 rf_gain = 30 #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

""" Note: if you experience audio underruns while CPU usage is 100%, you can:

• decrease samp_rate,
• set fft_voverlap_factor to 0,
• decrease fft_fps and fft_size,
• limit the number of users by decreasing max_clients. """

==== I/Q sources ====

(Uncomment the appropriate by removing # characters at the beginning of

the corresponding lines.)

There are guides for setting may different SDR hardware including AirSpy,

AFEDRI-SDR, RTL-SDR in direct sampling mode, etc. in the Wiki:

https://github.com/simonyiszk/openwebrx/wiki

You can use other SDR hardware as well, by giving your own command that

outputs the I/Q samples... Some examples of configuration are available here (default is RTL-SDR):

>> RTL-SDR via rtl_sdr

start_rtl_command="rtl_sdr -s {samp_rate} -f {center_freq} -p {ppm} -g

{rf_gain} -".format(rf_gain=rf_gain, center_freq=center_freq, samp_rate=samp_rate, ppm=ppm)

format_conversion="csdr convert_u8_f"

start_rtl_command="cat /tmp/osmocom_fifo"

format_conversion=""

start_rtl_command="/home/kesh/SDRPlayPorts/build/play_sdr -b 1536 -i 0 -v 1 -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"

start_rtl_command="/home/kesh/SDRPlayPorts/build/play_sdr -b 1536 -s

{samp_rate} -f {center_freq} -x 16 -g {rf_gain} -y 0 -".format(rf_gain=rf_gain, center_freq=center_freq, sam$

format_conversion="csdr convert_s16_f"

start_rtl_command="hackrf_transfer -s {samp_rate} -f {center_freq} -g

{rf_gain} -l16 -a0 -q -r-".format(rf_gain=rf_gain, center_freq=center_freq, samp_rate=samp_rate, ppm=ppm)

format_conversion="csdr convert_s8_f"

""" To use a HackRF, compile the HackRF host tools from its "stdout" branch: git clone https://github.com/mossmann/hackrf/ cd hackrf git fetch git checkout origin/stdout cd host mkdir build cd build cmake .. -DINSTALL_UDEV_RULES=ON make sudo make instal """

>> Sound card SDR (needs ALSA)

I did not have the chance to properly test it.

samp_rate = 96000

start_rtl_command="arecord -f S16_LE -r {samp_rate} -c2

-".format(samp_rate=samp_rate)

format_conversion="csdr convert_s16_f | csdr gain_ff 30"

>> /dev/urandom test signal source

samp_rate = 2400000

start_rtl_command="cat /dev/urandom | (pv -qL `python -c 'print

int({samp_rate} * 2.2)'` 2>&1)".format(rf_gain=rf_gain, center_freq=center_freq, samp_rate=samp_rate)

format_conversion="csdr convert_u8_f"

>> Pre-recorded raw I/Q file as signal source

You will have to correctly specify: samp_rate, center_freq,

format_conversion in order to correctly play an I/Q file.

start_rtl_command="(while true; do cat my_iq_file.raw; done) | csdr

flowcontrol {sr} 20 ".format(sr=samp_rate21.05)

format_conversion="csdr convert_u8_f"

>> gr-osmosdr signal source using GNU Radio (follow this guide:

https://github.com/simonyiszk/openwebrx/wiki/Using-GrOsmoSDR-as-signal-source )

start_rtl_command="cat /tmp/osmocom_fifo"

format_conversion=""

==== Misc settings ====

shown_center_freq = center_freq #you can change this if you use an upconverter

client_audio_buffer_size = 5

increasing client_audio_buffer_size will:

- also increase the latency

- decrease the chance of audio underruns

start_freq = center_freq start_mod = "nfm" #nfm, am, lsb, usb, cw

iq_server_port = 4951 #TCP port for ncat to listen on. It will send I/Q data over its connections, for internal use in OpenWebRX. It is only accessible from the localhost by default.

access_log = "~/openwebrx_access.log"

==== Color themes ====

A guide is available to help you set these values:

https://github.com/simonyiszk/openwebrx/wiki/Calibrating-waterfall-display-levels

default theme by teejez:

waterfall_colors = "[0x000000ff,0x0000ffff,0x00ffffff,0x00ff00ff,0xffff00ff,0xff0000ff,0xff00ffff,0xffffffff]" waterfall_min_level = -88 #in dB waterfall_max_level = -20 waterfall_auto_level_margin = (5, 40)

old theme by HA7ILM:

waterfall_colors = "[0x000000ff,0x2e6893ff, 0x69a5d0ff, 0x214b69ff,

0x9dc4e0ff, 0xfff775ff, 0xff8a8aff, 0xb20000ff]"

waterfall_min_level = -115 #in dB

waterfall_max_level = 0

waterfall_auto_level_margin = (20, 30)

For the old colors, you might also want to set [fft_voverlap_factor] to 0.

Note: When the auto waterfall level button is clicked, the following

happens:

[waterfall_min_level] = [current_min_power_level] -

[waterfall_auto_level_margin[0]]

[waterfall_max_level] = [current_max_power_level] +

[waterfall_auto_level_margin[1]] # # |____|____|____|> signal power

_waterfall_auto_levelmargin[0]/ |__ current_min_power_level

 | \_waterfall_auto_level_margin[1]_/

# current_max_power_level __|

==== Experimental settings ===

Warning! These are very experimental.

csdr_dynamic_bufsize = False # This allows you to change the buffering mode of csdr. csdr_print_bufsizes = False # This prints the buffer sizes used for csdr processes. csdr_through = False # Setting this True will print out how much data is going into the DSP chains.

nmux_memory = 50 #in megabytes. This sets the approximate size of the circular buffer used by nmux.
