Max range and performance within limitations

Just asking to be sure:

Have you contacted the ukhas group? They have a lot of practical information and a really nice tracker map. Their website is at
http://habhub.org/

They have a google groups mailing list, and an IRC channel with helpful people.

I myself wrote a kind of bridge between TTN and the habhub tracker site, that receives telemetry packets from TTN and forwards them to habhub for display on the map:
