Well if you don’t want to touch the Terminal.app you can download Qt Creator, load the project and hit “Build Project”. The CLI way of doing it is ‘mkdir build && cd build && qmake ../multimon-ng.pro && make && sudo make install’ after installing a compiler (clang/GCC) as well as qmake.

I’m using rtl_fm -f * -g 19.1 -s 22050 -l 50 – |multimon -t raw -a ZVEI /dev/stdin

* tested diffrent frequ.

Zvei sounds like this: http://upload.wikimedia.org/wikipedia/commons/9/9a/5-Ton-Folge-88022.ogg
works fine with fms32 or radio-operator etc

thanks for your help and bye the way great work, multimonNG decodes POCSAG very good

I haven’t verified ZVEI since I forked multimon. Send me a sample and I’ll look into it.

The format used by multimonNG on stdout isn’t TNC2 format required by Xastir so netcat can be used changing output format in multimonNG

I use this one:

rtl_fm -N -l 6 -E -f 173240000 -s 22050 -o 4 -g 100 – | tee >(./multimon -a POCSAG1200 -f alpha -t raw /dev/stdin) >(play -t raw -r 22050 -e signed-integer -b 16 -c1 -V1 -q -) > /dev/null

to here what’s being received.

It’s a self compiled version from github run under ubuntu.

Could you paste the actual command you were using? The version of multimonNG I have packaged doesn’t support standard input via pipe. Instead you can have it read from “/dev/stdin”. The latest version does support getting piped into and I will include it with the next bundle.

Hi and thanks for the great job with multimonNG and Gqrx.

I got some problem when using multimonNG, maybe you know what to do:

When piping the rtl_fm output to multimonNG it doesn’t decode anything. First I thougt, the signal was to weak, but I tested it this way:
- record with Gqrx
- mix down to mono
- normalize the sound
-> multimonNG is able to decode it.

So maybe is rtl_fm the problem – beware – crazy testing:
- I “pipe” the sound via iMacs LineOut to a Windows Notebook with FMS32 installed
-> FMS32 can decode the sound.

Any idea, why multimon wouldn’t eat the plain output of rtl_fm?
