Everyday Balloon Fox Hunting by Peter PA3PM


An entertaining 18 minutes although you might start to wonder about the anorak count in this guy’s wardrobe. He hunts radiosondes. Often at night, often in the mud.

A radiosonde is a battery-powered telemetry instrument carried into the atmosphere usually by a weather balloon that measures various atmospheric parameters and transmits them by radio to a ground receiver. Modern radiosondes measure or calculate altitude, pressure, temperature, relative humidity, wind, cosmic ray readings and geographical position. Apparently when they fall to earth, they’re fair game.

Peter PA3PM takes you on a hunt, explains how to build a simple tracker to search for weather balloons, and (at 10m40s) he includes a section on “Build a surveillance station”. Don't forget your Swiss Army knife.
