#This Script is a combination of two scripts.
# https://github.com/craigerl/aprs-send-weather/blob/main/aprs-send-weather.sh  
# https://groups.io/g/direwolf/message/7007
# Both by Craig KM6LYW
# The combination script was assembled and very slightly modified by Robert W9RWB
# The purpose is to send messages via the commandline rather than using a client such as YAAC or Xastir.
# read destination callsign and message from command line
