The GB3LV IRLP/Echolink node, located in Enfield, north London, is now powered by a tiny Raspberry Pi computer running a reduced version of Linux Debian and a version 3 IRLP interface.
This reduces the energy and physical footprint of the node dramatically.
This development over the past 3 months, has only been possible because of a great deal of work done by Dave Cameron, VE7LTD.
The link transmitter is a Yaesu FT-7100.
The Raspberry Pi computer cost about £25 and needs a PSU (just a phone charger), cables and SD card operating system. The node requires no screen, mouse or keyboard when running.
