Installation of PagerMon Client on RPi

Throughout my investigation in HAM Radio, I have been learning about POCSAG which is a basic communication method used by billions of Pagers world-wide.

Here are my notes on installing the client on a RPi and sending the decoded messages to a PagerMon Server.

PLEASE NOTE: Instructions still a work in progress…
