Configure Trunk Recorder

There are 3 configuration options

broadcastifyApiKey      : specified for each system entry in your trunk-recorder config
                          this is the API Key issued to you by the administrator

broadcastifySystemId    : specified for each system entry in your trunk-recorder config
                          this is the unique system identifier issued to you by the administrator

broadcastifyCallsServer : specified SYSTEMWIDE in your trunk-recorder config
                          should always be set to: "https://api.broadcastify.com/call-upload"

Example Trunk Recorder configuration

• API Key Example: "9c3e3b1d-324f-11aa-bd8b-0ec68ab9ccec"
• System ID Example: "91"
• Note: The "ppm" and "gain" values are for example only. Use GQRX or similar to adjust them for your particular SDR sources and optimum SNR.
• Note: The "shortName" value cannot have spaces or special characters; this will cause uploads to fail.

 The README.md file lists all the configuration options.
