MULTIMON now supports FLEX pagers on Raspberry Pi

[essexRXer]

Some time back I had set up an application that decoded POSCAG pager signals on my raspi, at the time FLEX was too heavy for the beefed up vertion, however upon looking again, there has been an update to this awesome piece of software.


You need.

Raspberry PI (with SSH enabled)
Powered Hub
SDR RTL dongle
A PC *optional

# Install dependencies
sudo apt-get update
sudo apt-get -y install git cmake build-essential libusb-1.0 qt4-qmake libpulse-dev libx11-dev

# Fetch and compile rtl-sdr source
mkdir -p ~/src/
cd ~/src/
git clone git://git.osmocom.org/rtl-sdr.git
cd rtl-sdr
mkdir build
cd build
cmake ../ -DINSTALL_UDEV_RULES=ON
make
sudo make install
sudo ldconfig

# Fetch and compile multimonNG
cd ~/src/
git clone https://https://github.com/craigshelley/multimon-ng.git
cd multimonNG
mkdir build
cd build
qmake ../multimon-ng.pro
make
sudo make install

Then make a blacklist so that the sdr dongle does not trow you out.

/etc/modprobe.d/blacklist.conf

adding these lines:
blacklist dvb_usb_rtl28xxu
blacklist rtl2830
blacklist dvb_usb_v2
blacklist dvb_core

Now when you reboot, do this line:

rtl_fm -f 153.350M -s 22050 | multimon-ng -t raw -a POCSAG512 -a POCSAG1200 -a POCSAG2400 -a FLEX -f alpha /dev/stdin

if you are doing this from SSH this can be viewed by any device that you are using in the house!
More can be done with a web server, but I am struggling to get mine working so I will not share this out yet
