Thanks folks,
I've installed the PilotAware operating system - all well.
Now having issues with my USB dongle. I ordered a dongle with the correct chipset, but the boot fails during the hotspot setup.
I plugged in a (very) old TP-LINK TL-WN721N and this appears to work, (but is a huge early days dongle), but I'm waiting for a license key to see if I can get it talking to SkyDemon.
As a matter of interest Adrian - what wi-fi dongle did you order (is there an EBay link)?
