Oh what a day!
Earlier today I managed to communicate via mesh networks with my friend @stereo in Germany... some 400+ km away.
It only took 6 hops... the third one in the chain was the iconic Jungfraujoch radio relay station (https://en.wikipedia.org/wiki/Jungfraujoch_radio_relay_station).
So exciting!
I can't thank Ralf enough for his help with this... I would have been completely lost without his guidance.
Let the fun mesh adventures begin!
