Having got started with APRS, I have implemented a Rx-only iGate using a Raspberry Pi with a RTL-SDR dongle and direwolf software. This was done initially using the project detailed by G6NHU, but extended to use the latest versions of software.
This is currently on APRS-IS as M0RNW-10.
It is envisaged that this will become a two-way iGate/digipeater with the use of a Baofeng transceiver, together with a arduino based weather station (in development).
