I'm sorta with N2NEY on this aprs , story warning - I never heard of aprs until a few months back as someone mentioned on 2m via a repeater that someone had it all set-up , so someone sent me a email with an address thingy/callsign and said check that out . So , over the next few days/weeks sure enough i could see someone moving about on the map , going here and there and back (someones qth is around 120klm (70Mile) as the crow fly's from here . Someone dropped in here at the qth a few weeks later as someone and someone was going right past , 1st time and we discussed and i was shown the aprs setup and how it all worked , fascinating imo , but a suspicion was developing which i'll end with . So , on the way home someones someone was driving and we were in contact 2m fm simplex and i was checking out the map as well , then i noticed and said "if i was a stingy cop (as stereotypical normal) i have just cost you $230 for doing 10kph over the speed limit and 3 points off ya licence to boot" , the response after having a look at the speedo end was LOL yep it sure was and on the map the data showed back to 100kph straight away , suss stuff . The much awaited end , all those satellites recently being put up and all that talk of future "monitors" fitted in your vehikkles , Mobile phones and the way it can monitor "between " cells which is already happening = automated fine dispenser LOL , all for Your Safety , i know too they be working on a Fart Tax ! , imo of course .
