The flight of AH3 is to attempt to stabilise the radio's temperature and therefore maintain the nodes frequency and data rate. text/html 2020-06-27T23:02:01+00:00 Anonymous (anonymous@undisclosed.example.com) https://ukhas.net/wiki/balloon_nodes:aj2?rev=1593298921&do=diff AJ2 UKHASnet Balloon Launch Launch Details * Launch 22/5/16 10:00 * Preston St Mary, Suffolk * Howyee 1600gram balloon * Aiming for float around 30km AJ2 * LPC812 Etna board (RFM69HW) * Resistor heater controlled by mosfet with PID control text/html 2020-06-27T23:02:01+00:00 Anonymous (anonymous@undisclosed.example.com) https://ukhas.net/wiki/balloon_nodes:ball1?rev=1593298921&do=diff BALL1 Aim To test UKHASnet network in the air on a balloon, to be launched on a latex balloon and act as a repeater for ground stations. To test range and whether it is possible to uplink data to the airborne node.
