My good friend WA2AAX, now a silent key, told of a visit he once made to the Arecibo Observatory in Puerto Rico. During a lull in operation they let him traverse the catwalk spanning the 'dish' (a spherical mesh 1,000 ft diameter built inside a natural sinkhole) as the moon reached its zenith. Scanning his VHF HT he was able to hear many moonbouncing HAMs and even voice traffic from repeaters in the US. With a standard offset he was even able to make a brief contact with someone on a faraway VHF repeater before the celestial mechanics drifted out of alignment. A 2,000 mile QSO on VHF with a handheld, via the Moon. He considered it his finest Geek moment.

One of Arecebo's missions was to listen on Soviet and Sino transmissions, or nuke tests, via moon bounced transmissions.

Great story! That’s sort of the Ham equivalent of the XKCD with the “real programers use a butterfly”[1]
Even though my household weren’t HAM’s at the time, he’d “call” us every few days through a “phone patch” to give status updates in the middle of the Pacific.
Basically, he’d make connections to various HAM’s somewhere, trying to find someone who could do a “phone patch”. That person would then connect the audio to their phone, call my house collect, and we could have a two-way conversation. Pretty cool stuff.
Back in the 90’s when I had my license I thought packet radio was cool as hell. Checking your email in the middle of a field? Amazing. Of course that’s all obsolete now.
And then just for the ultimate geek factor. You know what the very first communication satellite was, right? The moon! HAM’s still do “moonbounce” communications to talk to people on the opposite side of the planet by bouncing signals off the moon. Requires very directional antennae, and brings with it the ultimate latency. But that’s some serious geek cred there.
