+# Pi-StAPrS - Script for Pi-Star & APRS
+
+Gathers GPS and Pi-Star Info to beacon to APRS-IS as location & comment
+
+## About
+
+This script was originally written a couple of years ago to do two things:
+
+```
+gather & parse GPS information for an APRS packet
+scrape Pi-Star for Talkgroup/Reflector for APRS comment
+blast those to APRS-IS
+```
+
+The scripts were originally written to run directly on the RPi running Pi-Star;
+scraping the information locally and getting GPS from another Pi running 
+gpsd. A simple PHP interface was hacked together to turn the beacon on
+and off. The entire thing was just permanently set as an every 5-minute
+cronjob. 
+
+Pi-Star has some sort of GPS stuff built-in to it; but I couldn't figure out
+how to make it work. It's also been a few years since I tried to even run it in
+it's current state. I plan on making use of it soon; so it will likely see re-
+writes. In fact the method of scraping has changed entirely. 
+
+I also lost the php that handled the activation.
+
+Some of this has been resurrected as a hotspot information display. I will 
+update this spot when I get it's repository up. The original page is at:
+https://pickmy.org/?page_id=136
