[arm-allstar] User Record/Playback DVR Function (Signal check)

[Randy Neals]

Wondering if anyone has devised a way to implement a "User DVR"
record/playback function in Allstar?


To be clear in what I'm asking, here's how one commonly available hardware
controllers describes this capability:

User DVR Recording
You can program a Command Macro to allow users to record themselves in
order to check how well they’re “getting into the repeater”.  This Macro
Function will record, playback and then erase the DVR Track (this function
uses DVR Track 19).
