you have got a very small bandwidth - I would widen that up a fair bit and what gain are you using or are you using AGC? If so, I would turn AGC off and manually adjust the gain.

OK your giving me too much credit. What would you set the offset to? I can untick automatic gain. I am very new to this stuff and cubicsdr has zero documentation.

It was turning off auto gain and the antenna. Ha! Working well on Elementary os Freya(Ubuntu 14.04) with a 15" whip. Thanks for the help.

Use the Start here link on
http://www.sdrplay.com/starthere.php
Download and install api/driver.
Use PyBombs to install gr-osmosdr and gnuradio. I had pip already so used that method.
https://github.com/gnuradio/pybombs
If you want to use the gnuradio you have to add thi line.

Code: Select all

var: {config_opt: ' -DENABLE_NONFREE=TRUE'}

in the recipe file gr-osmosdr.lwr in pybombs/recipe/, before the "inherit: cmake" line.
https://github.com/gnuradio/pybombs/issues/201

Then go straight to the cubicsdr wiki linux install page and follow
https://github.com/cjcliffe/CubicSDR/wiki/Build-Linux

I originally used the soapysdr github page but that failed when I was working through cubicsdr install instructions.
So removed soapy and reinstalled it while working through Cubicsdr install page.
At the bottom of that page is the sdrplay module install it.(I installed both of them).
I then had to blacklist a couple modules.
https://linuxconfig.org/how-to-blacklist-a-module-on-ubuntu-debian-linux

After that I turned off auto gain. It will be on every time you start Cubic.
Then I received sma cable and removed my wifi antenna ;)
Success.

Thank you again for all your help.

Hi - just posting this for info in case others are having trouble wrestling with Pybombs :)

Instead of adding the -DENABLE_NONFREE=TRUE switch to the Pybombs recipe file for gr-osmosdr, I built gr-osmosdr from source using the instructions in Section 5 of the SDRPlay Linux install technical note: http://www.sdrplay.com/docs/Mirics_SDR_ ... e_r2p0.pdf

If, like mine, your GNURadio installation is in a sandbox, you'll need to use the following cmake line instead of the one in the tech note:

Code: Select all

cmake ../ -DENABLE_NONFREE=TRUE -DCMAKE_INSTALL_PREFIX=/path/to/your/sandbox


Do everything else as per the tech note. That worked nicely for me - GNURadio and SDRPlay now playing together happily!
