Amateur radio club sends transmitter into the sky
George Herald
|George Herald
A Pico balloon carrying a weak signal propagation reporter (WSPR) beacon was sent into the atmosphere from the outskirts of George on Monday morning, 30 June.
Launched by amateur radio enthusiasts from the Eden Radio Club, the beacon is expected to transmit radio signals in the 10m band for about a year before it stops working. Operating at the extremely energy-efficient side of the scale, the solar-powered beacon operates at a transmit power of only 20 millivolts (mV) - significantly below the voltage levels used in typical household systems. Using the WSPR protocol, the beacon transmits location, altitude, wind speed, temperature and solar panel voltage data every 10 minutes.
