# This is a sample application that "plays" a voice tranmission from a file
# that was created with record.py. The file is just a pickle of an entire
# transmission.
#
# This program consults a list of "trigger groups" for each timeslot that
# will initiate playback. When playback occurs, several items are re-written:
# Source Subscriber: this DMRlink's local subscriber ID
# Source Peer: this DMRlink's local subscriber ID
# Timeslot: timeslot of the tranmission that triggered
# TGID: TGID of the message that triggered it
