Our SPOT is used as a secondary tracker and we have been trying for a while to get its tracking updates to aprs.fi. We use aprs.fi as the main tracking map and now we have finally got the SPOT follow-me 10minute updates appearing on aprs.fi. To do this we use an intermediate site called positlogger.net […]
