# playnews v0.8 - WA3DSP 11/2015
#
# Script to download ARRL News or ARN and divide into 2.5 minute segments with breaks.
# Includes voice messages before play, at breaks, and after play.
# This script can be configured for global playback!
# DO NOT run this on a multi-node connected circuit without consideration.
# Change MODE to localplay for strictly local node play.
#
# This code is written to work on the hamvoip.org BBB/RPi2 Allstar releases
# All required packages are pre-installed on those systems.
#
# For proper operation holdofftelem in rpt.conf should either not be defined or
# defined as =0  This stops keyups from delaying the news during its playing
#
# You can run this script from a cron job or from the command line at least
# 15 minutes before the defined run time (TIME value) but it can be scheduled
# anytime within 24 hours prior to the run time.
#
# cron example -
#
# Prime news for play every Tuesday at 8:30PM - actual playtime set by defined
# comand line TIME parameter. If Playtime is 9PM (2100)
# This would send pre warnings at 8:50 and 8:55 PM.
#
# Start a cron job every tuesday at 8:30 PM to run at 9 PM the same day
# and play ARRL news on node 40000, globally
