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.
