README.md

multimon-ng a fork of multimon. It decodes the following digital transmission modes:

  • POCSAG512 POCSAG1200 POCSAG2400
  • FLEX
  • EAS
  • UFSK1200 CLIPFSK AFSK1200 AFSK2400 AFSK2400_2 AFSK2400_3
  • HAPN4800
  • FSK9600
  • DTMF
  • ZVEI1 ZVEI2 ZVEI3 DZVEI PZVEI
  • EEA EIA CCIR
  • MORSE CW

The following changes have been made so far:

  • Fixes for x64
  • Basic functionality on Mac OS X (Soundcard/OSS input is unsupported)
  • DUMMY_AUDIO "backend" (Gets rid of the OSS dependency, breaks audio in doing so)
  • ONLY_RAW disables the format conversion while getting rid of posix dependencies
  • Option NO_X11 to disable the X11 dependency
  • Brute-Force BCH implementation for POCSAG forward error correction
  • Verbose mode is now listed in -h
  • Continued EAS/SAME development. The decoder now works, but it should be considered "alpha" quality. Do not rely on it for the reception of emergency alerts!
  • Improved portability
  • Compiles on Windows (MinGW or Cygwin) without format conversion
  • Windows native audio
  • PulseAudio support
  • Accepts raw samples as piped input
  • CSV output
  • FLEX decoder

In addition to the deprecated legacy Makefile there is also a file for qmake which is the preferred way of building multimon-ng. It's recommended to use qmake to generate the Makefile.

mkdir build
cd build
qmake ../multimon-ng.pro
make
sudo make install

The installation prefix can be set by passing a 'PREFIX' parameter to qmake. e.g: qmake multimon-ng.pro PREFIX=/usr/local

So far multimon-ng has been successfully built on OS X, Debian, Ubuntu, Windows and FreeBSD. (On Windows using the Qt-MinGW build environment, as well as Cygwin and VisualStudio/MSVC)

Files can be easily converted into multimon-ng's native raw format using sox. e.g: sox -t wav pocsag_short.wav -esigned-integer -b16 -r 22050 -t raw pocsag_short.raw GNURadio can also generate the format using the file sink in input mode short.

You can also "pipe" raw samples into multimon-ng using something like sox -t wav pocsag_short.wav -esigned-integer -b16 -r 22050 -t raw - | ./multimon-ng - (note the trailing dash)

Packaging

qmake multimon-ng.pro PREFIX=/usr/local
make
make install INSTALL_ROOT=/
