Setting up the Airspy R2

4 Jun

Add udev Rules
sudo vi /etc/udev/rules.d/99-airspy.rules

SUBSYSTEMS=="usb", ATTRS{idVendor}=="1d50", ATTRS{idProduct}=="60a1", MODE:="0666"

sudo udevadm control --reload-rules

CMakeLists.txt for dial_tone.cc

30 May

If you want to compile dial_tone.cc outside of either the GR source tree or OOT module, this is the minimum required CMakeLists.txt (courtesy of Johnathan Corgan)

Setting up the Ettus USRP E310

29 Jun

Add udev Rules for E310 Serial Console
sudo vi /etc/udev/rules.d/99-usrp-e310.rules

SUBSYSTEMS=="usb", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6015", MODE:="0666"

sudo udevadm control --reload-rules

Serial Console Login
Plug in power and wait a few seconds for E310 to boot, then plug in microUSB.

dmesg to figure out the assigned serial port (i.e. /dev/ttyUSB4)

screen /dev/ttyUSB4 115200

Login as root

Setting Static IP
vi /etc/network/interfaces

# Wired or wireless interfaces
auto eth0
#iface eth0 inet dhcp
iface eth0 inet static
address 192.168.1.14
netmask 255.255.255.0
gateway 192.168.1.1
iface eth1 inet dhcp

GQRX Tips

21 Dec

QT5
Prior to installation of gqrx make sure QT5 is available by installing the following:
qt5
qt5-devel

Pulse Audio
Prior to installation of gqrx make sure pulseaudio is available during build by installing the following:
pavucontrol
pavumeter
pulseaudio-libs-devel

Install gqrx
git clone https://github.com/csete/gqrx.git
cd gqrx
mkdir build
cd build
qmake-qt5 ..
make -j8
sudo make install

Typical device strings
For the b200:
uhd,type=b200,nchan=1

For the X310 with LFRX in slot 2:
uhd,addr=192.168.40.2,subdev=B:A,nchan=1

For the X310 with WBX in slot 1:
uhd,addr=192.168.40.2,nchan=1

For the N210 with LFRX:
uhd,addr=192.168.1.13,subdev=A:A,nchan=1

When switching between devices in gqrx the gain control changes will segfault the application.  Fix this by deleting the “gains” section in:
~/.config/gqrx/default.conf

Sending gqrx audio to fldigi
Install fldigi with yum

Configure fldigi sound card to use pulseaudio, leaving server string empty

Launch pulseaudio volume control, and under recording tab, fldigi capture from monitor of built-in audio analog stereo, and set level to 0 dB.

Adjust fldigi waterfall upper signal level and signal range.

Setting up the Ettus USRP B200

10 Jun

Using a Syba SD-PEX20122 (VLI VL80x chipset) PCIE USB 3.0 controller and 1 meter cable

Add udev Rules
sudo vi /etc/udev/rules.d/99-usrp-b200.rules

SUBSYSTEMS=="usb", ATTRS{idVendor}=="2500", ATTRS{idProduct}=="0020", MODE:="0666"

sudo udevadm control --reload-rules

Realtime Priority
sudo vi /etc/security/limits.conf

# Add for USRP realtime priority
myusername – rtprio 99

Will require re-login

Update Firmware
sudo /usr/local/lib64/uhd/utils/uhd_images_downloader.py

Probe
uhd_find_devices --args="type=b200"

Benchmark
cd /usr/local/lib64/uhd/examples
./benchmark_rate --rx_rate 45E6 --args "type=b200, master_clock_rate=45E6"

Baudline Tips

20 Apr

Install extra Fedora fonts
sudo yum install xorg-x11-fonts-misc
sudo yum install xorg-x11-fonts-ISO8859-1-75dpi

Reading data file from GNU Radio
GNU Radio file sink with input type complex writes IEEE 754 single-precision floats:
f = scipy.fromfile(open("filename"), dtype=scipy.complex64)

Baudline file raw parameters
Decompression: OFF
Initial byte offset: 0
Sample Rate: custom
Channels: 2
Quadrature: ON
Flip Complex: ON
Decode Format: 32 bit float, little endian
Normalization: 1 maximum sample value

GNURadio Tricks

20 Apr

Dynamic recording of files
Create a QT GUI Check Box with ID “Record” and set type to Boolean, and Default Value to False.

Create a variable with ID “file_name” and set Value to:
'data.bin' if Record==True else '/dev/null'

Create a File Sink with file “file_name”
