HackRF Dire Wolf APRS Raspberry PI Zero

Why

To minimalize antennas and radios ... i'm using a Transverter on my Flex radio to use the 2M band, i use an TR 144 - PRO, Khune

This transverter has seperate RX out ... witch is connected to a AntennaJet AAS300DP, one of these outputs is connected to a HackRF SDR board that was laying arround. The SDR Board is connect to a usb/ethernet dongle for the Raspberry PI Zero.

Install on Linux - Raspberry PI Zero ... Buster Release (2020)
