We got 446km.

We achieved something we are proud of. On 6th June 2018 we sent out packets over TTN. Our location was approximately 600m high in the Pennines around Sheffield at a location known as Barrow Stones (maybe the one seen in your article). To our surprise, a single packet was picked up at Delft, all the way over in the Netherlands. The gateway is in fact owned/run by the Delft University of Technology. This is a distance of 446km. Here is our proof this was achieved: https://ttnmapper.org/special.php?node=1279_b370&date=2018-0...
