Receiving Pager messages on a RPi

Thu Oct 25, 2012 1:20 am

I've been messing around with a £12 USB DVB-T dongle as they can be turned into a cheap SDR and it's been a lot of fun.

First I compiled rtl_sdr and made sure it was working, which had the side benefit of turning my Pi into an FM receiver :-)

I then compiled multimonNG to work as a decoder, then glued them both together:

Code: Select all

rtl_fm -f 153.353e6 -g 100 -s 22050 -l 310 - |multimon -t raw -a POCSAG1200 -f alpha /dev/stdin
rtl_fm tunes the DVB-T dongle to 153.353MHz and uses FM demodulation on the signal, the output of which is passed to multimon which is then decoded.

At least I found a use for my Pi that isn't media/MAME related :-)
