A text user interface frontend for multimon-ng. mmng-ui will listen on a chosen UDP port (defaults to 8888) for raw streams from software like SDR++, use multimon-ng to decode it, and show you POCSAG messages in a wonderful text interface. It will attempt to auto-detect the output format from multimon-ng, and if it looks like JSON, it'll use it.

Software that 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 code (CW), X10.

Give it a recording or stream of raw audio and it can try to make sense of it. This includes the output of utilities like rtl_fm.

A directory of e-mail addresses that can be used to send alerts to various mobile devices (phones, pagers, etc) via e-mail. Most of them consist of the phone number at some specific hostname.
