9M is used for Air to Ground support during wild land fires.
The set up being used is 2 SDR (software defined radio) usb dongles connected to a mini computer.
The software being used is Trunk Recorder operate the SDR's. Liquidsoap is used to upload the traffic to Broadcastify.
Trunk Recorder constantly monitors the control channel. When a selected talk group is detected on the control channel the computer tunes an SDR to the active channel. If more than one talk group becomes acitve on the system, the SDR's and program are able to record multiple converations at the same time. Once a transmission ends, a audio recording is made. Then it is set to be uploaded. If multiple files are recorded and need to be uploaded, they will uploaded in the order they are recorded.
This allows for the listener to hear every transmission.
