Re:Lorawan coverage testing from balloon

The balloon left Australia TTN coverage last night. Some stats:
- Max uplink range : 380km at 9400m altitude.
- Minimal RSSI = -137
- Max downlink range: 240km outside of Sydney at 9400m altitude.
- Coverage time; 40H

It appears that the outdoor coverage is more extensive in Melbourne compared to Sydney, with more gateways picking up balloon packets in Melbourne.
