Do the towers have a spec that allows outgoing email to anyone? And does the email always come from the same address? If not are you authenticating through smtp? This is so interesting, thanks for sharing!

Thats so cool.

My paternal grandfather was a ham radio guy.. he died before I could learn anything from any of it, and all his gear got sold at an estate auction.

I think its neat how you guys can bounce signals off the atmosphere to talk over the horizon to europe and shit.

Damn. That's cool.
