In the June Sky and Telescope magazine, page 11, a news blurb "Booster Impacts Lunar Farside" it mentions that the booster had a "now defunct amateur radio attached to the booster". This booster is apparently a Chinese Chang 5-T1 mission's booster.
Hadn't heard of a ham radio satellite system located in high Earth orbit, high enough to reach the Moon, which is about a quarter million miles out. Seems kinda far to operate it, but if we can use the Moon as a passive RF reflector, I suppose an active receiver and transmitter could work for us that far out?
