# Script to send POCSAG messages on multiple known frequencies to specified RIC
# This could be useful where the RIC is known, the frequency is unknown but 
#  suspected to be a former UK commercial paging network, but all other 
#  paramaters such as baud raud or inversion are unknown.
#
# You should be using this in an RF test chamber to avoid voilating the law. 
#  But if you're playing with pagers, you presumably already known this :)
