I have also been working on building some Raspberry Pi-based APRS and Winlink Packet gateways which will also be part of the repeater upgrades. The Raspberry Pi boards are connected to two TNC-Pi boards which are each connected to a VHF radio. The Raspberry Pi will run Xastir for APRS, and LinuxRMS for the VHF packet gateway to the Winlink system. The two radios will share a single antenna, using a Sinclair Q2222 duplexer.
