I love reading about the exploits of radio amateurs. This is some seriously impressive engineering too. It's surprising what one can do with off the shelf components assembled on a human scale (instead of microwave frequencies which need much smaller circuits). Also, there's a certain beauty in staying close to the physical layer and working the airwaves yourself.

This antenna array is used for EME. For those not familiar with that acronym, it means using the moon as a radio reflector to send signals back to earth: https://en.wikipedia.org/wiki/Earth%E2%80%93Moon%E2%80%93Ear...

Just 10W of RF to hear your own voice relayed by the moon is insane
