RTLSDR-Airband

Here's an example with RTLSDR-Airband:

Requirements

At the time of this writting, this will work only with the unstable branch of RTLSDR-Airband where the pr #163 has been merged.

RTLSDR-Airband's configuration

The trick here is to split audio by transmission and to leverage to filename_template to pass the system_id and talkgroup_id, which can then be utilized by Rdio Scanner's dirWatch.mask. So generated files will look like 61_118900_20200711_111311_118900000.mp3.

filename_template = "61_118900";
split_on_transmission = true;

Rdio Scanner's configuration

"dirWatch": [
      {
        "deleteAfter": true,
        "directory": "/home/radio/rtlsdr-airband/audio_files",
        "extension": "mp3",
        "mask": "#SYS_#TG_#DATE_#TIME_#HZ"
      }
]

The dirWatch metatags will then translate to:

Metatag	Value
#SYS	61
#TG	118900
#DATE	20200711
#TIME	111311
#FREQ	118900000
