I tried to get the SDRPlay running unter Linux, but I have a lot of trouble.
No configurations works without problems or crachs.

1.)
sudo apt-get update && apt-get upgrade

2.)
Download the latest API from sdrplay and install it
(SDRplay_RSP_MiricsAPI-Linux-1.95.3.run)

3.)
I use the file Mirics_SDR_API_Linux_install_technote_r2p0.pdf for compile all necessary sources.
gqrx works and I get a spectrum from the device. But if I change the sample rate, the hole system freeze after a few seconds. I did not find a entry in the logs or a core dump.

4.)
I try to install CubeSDR. I use this description:
https://github.com/cjcliffe/CubicSDR/wiki/Build-Linux

The soapy + liquid-dsp + wxwidget seems to work. But if I start CubicSDR, I get an illegal instruction and CubicSDR crash.

I added the command "ulimit -c unlimited" and tries again.
I get a core file and if I open ddd ./CubicSDR core and start the debugger, I get a problem in liquid-dsp/src/nco/src/nco.c

5.)
I try to install soapy and gqrx via the ppa

See https://github.com/pothosware/pothos/wiki/Ubuntu & http://gqrx.dk/download/install-ubuntu

gqrx found a Mircis MSSI2500 default/Device String miri=0, but it is not possible to slelect an input rate and I did not get a spectrum or audio.
If I start gqrx in an terminal, I get this output:

Between Step 3/4/5, I deleted all files via make uninstall or used apt-get autoremove and rebooted.
Any Idea how to get a running SDRPlay?

Hi Andreas,

getting SDRPlay to work in Ubuntu 16.04 is not easy. If possible, try with an USB3.0 port, this seems to work on most machines.
There is a patch for Soapysdrplay that fixes this, but you have to get soapysdrplay from git and build it from source.

I have cubicsdr running here, built from git about one week ago. I'll check with current git later.

I am using gqrx, so I am quite familiar with the problems here.

You say the miri modules are blacklisted, the gqrx startup messages seem to indicate that this is not working. What does lsmod say?

OTOH, gqrx needs some work anyway.

You can go 2 ways:

1. gr-osmosdr with SDRPlay support:
You have to build gr-osmosdr from source with the non free drivers enabled. Don't know by heart how to do this, please search the net.

2. gr-osmosdr via soapysdr/soapysdrplay
This is what I am doing. This needs a patch in gr-osmosdr so that the soapysdr devices are enumerated on startup.

Hello Wolf,

my PC didn't have USB 3, I have to buy an PCIe Card with Linux support.

But I found some reason, why CubicSDR crashes and a workaround.
On my PC the compiling of libliquid-dsp didn't work correct.
The makescript didn't link the libfft, but it is building the lib. The libfft is installed.

Last line of make
ldd local
ldd from skywave

Code: Select all

gcc -shared -Xlinker -soname=libliquid.so -o libliquid.so -Wl,-whole-archive libliquid.a -Wl,-no-whole-archive -lfec -lfftw3f -lm -lc 
fxxx:~/src/CubicSDR/liquid-dsp$ ldd libliquid.so
	linux-vdso.so.1 =>  (0x00007ffe98760000)
	libfec.so => /usr/local/lib/libfec.so (0x00007f2ca886d000)
	libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f2ca8564000)

	linux-vdso.so.1 =>  (0x00007fff35bdf000)
	libfftw3f.so.3 => /usr/lib/x86_64-linux-gnu/libfftw3f.so.3 (0x00007fe2f0a15000)
	libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007fe2f070c000)
	libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fe2f0342000)
	/lib64/ld-linux-x86-64.so.2 (0x00005636543d5000)

I use a Live CD Skywave for testing and copy the libliquid and the CubicSDR.
I put the both lib to /usr/local/lib and CubicSDR works.

GQRX works sometimes with the gr-osmosdr Soapy-driver.
But if it's crash, I have to disconnect SDRPlay form the USB-Port.
