![]() ![]() Doing so I found POCSAG (pager) transmissions which I tried to decode using multimon. for the Debian GNU/Linux system (but may be usedīy others). Due to my recent acquisition of an RTL-SDR compatible radio module (Some would call it DVB-T stick) I started playing with radio transmissions. The DTMF and ZVEI decoders have more frequent spurious detection In some countries, this software should therefore only be used to monitor Please note that monitoring commercial services may be prohibited So to decode (only) DTMF tones on the sound With no input file specified, the program listens directly to the Multimon-ng -s SCOPE -t wav /tmp/message.wav The -a and -s options may be given multiple times to specify the desired listĭecode signal modulations from a sound file /tmp/message.wav HAPN4800 FSK9600 DTMF ZVEI1 ZVEI2 ZVEI3 DZVEI PZVEI EEA EIA CCIR MORSE_CW ![]() Where is one of: POCSAG512 POCSAG1200 POCSAG2400įLEX EAS UFSK1200 CLIPFSK FMSFSK AFSK1200 AFSK2400 AFSK2400_2 AFSK2400_3 Add a label to the front of every printed line SE, SI -o CW: Set threshold for dit detection (default: 500) -d CW: Dit length in ms (default: 50) -g CW: Gap length in ms (default: 50) -x CW: Disable auto threshold detection -y CW: Disable auto timing detection -timestamp Add a time stamp in front of every printed line -label C POCSAG: Set charset (default: US), where is one of: US, FR, DE, Lower levels increase performance and lower false positives.
