These plugins have a lot of bugs and they have been removed trom the build. Original sources still exist in the tree. So current version only supports the following hardware:
Funcube Dongle Pro+ support will need "libasound2-dev" installed. ("libhid" is built from source). Install the rules file "fcdpp.rules" in "/etc/udev/rules.d" to gain the "root access" needed to control the dongle.
Funcube Dongle Pro+ USB drivers are broken on some hardware with recent kernels. It works well for me with an Atom Chipset, which has Full Speed USB ports, or a "Valleyview" Chromebook (kernel 3.10). A Desktop with the "same" chipset needs kernel 3.2, available with Debian 7 "wheezy". YMMV.
A complete new plugin has been written for the BladeRF that interfaces libbladeRF directly. Osmosdr/GnuRadio interface is not implemented correctly and has a lot of bugs as mentioned previously and was not reasonably usable with the BladeRF.
If you use your own location for libbladeRF install directory you need to specify library and include locations. Example with `opt/install/libbladerf` with the following defines on `cmake` command line:
Use `cmake ../ -DV4L-RTL=ON` to build the Linux kernel driver for RTL-SDR (Experimental). Needs a recent kernel and libv4l2. Will need extra work to support SDRPlay. Needs `cp KERNEL_SOURCE/include/linux/compiler.h /usr/include/linux/` and `cp KERNEL_SOURCE/include/uapi/linux/videodev2.h /usr/include/uapi/linux/` and package `libv4l-dev`.
For non standard installations of RTL-SDR library, the GNU Radio runtime and gr.osmocom drivers use the following variables in the cmake command line. The paths specified are just examples:
- RTL frontend will have bad aliasing in noisy environments. Considering the size of the hardware there is no place for proper filters. With good filtering and a good antenna up front these devices work remarkably well for the price!
- Aliasing can be annoying for broadcast FM. In this case try to shift the signal until you find a clear background for your station. This is a limitation of the RTL hardware so just use this workaround.
- NFM demodulation without using atan and smooth squelch with AGC suppressing most clicks on low level signals and hiss on carrier tails. Only useful modulation comes through.
- New plugin for BladeRF interfacing libbladeRF directly
- Corrected the nasty audio band resampling bug preventing use of sample rates that are not power of 2 multiples of 48kHz. This was because the resampling ratio was calculated with an integer division instead of a float division.
- As a consequence of the above added more interesting values for the available sampling rates of the BladeRF plugin
- Channel analyzer bandwidth up to half the available RF (IF) bandwidth (was 48k fixed)
- Enhanced scope display and controls: scale display, better X (time) and Y scales control, grid fit to scale, effectively implementing triggers, trigger on magnitude and phase, properly handling time shift, ...
- Enhanced spectrum display: Histogram: wider decay range, make stroke and late holdoff adjustable. Added option to show live spectrum (had only max hold before).
- Enhanced channel analyzer: enhanced scope and spectrum displays as mentioned above, make the spectrum display synchronous to scope (hence triggerable a la E4406A).
