So after all the testing, and building of the Direwolf Raspberry Pi Tracker, I took it to the US.
It performed really well in California.
I tethered to my mobile phone and discovered that I needed to sit in the personal hot spot screen for the device to actually connect every time.
Not sure why, but from the second picture, I do wonder if it was the cause of the loss of packets in Texas.
In there, but did not capture it as I don’t think it worked correctly was the drive down Elm Street – where Kennedy was assassinated.
