Our very own Rob Chipperfield will be talking about APRS (Amateur Packet Reporting System). Find out how those strange noises on 144.800MHz carry everything from position data to weather reports to text messages.

The talk will start at 1900 in the Bateman Auditorium, Gonville and
Caius College (see here for location in the college). Doors will be open from 1840. Afterwards (about 2000) we will adjourn to the Maypole for food.
