If you find AMSAT interesting, you'll probably also enjoy the high altitude ballooning (HAB) projects. This guy [0] built an 11-gram transponder payload and floated it up on what was, essentially, a mylar party balloon. It circled the globe at least once and came ashore over the northwestern U.S. near Tacoma, WA and I was lucky enough to pick it up on a handheld radio while standing in my backyard [1].

Hey Chris, Dave KI6YMZ here :) We did a SOTA peak many years ago in CO together!

You should check out HIRF-6 as well. Similar payload, and has been airborne since September of 2016!

    Hey Dave! That was a fun trip. For those that are wondering what we're talking about, Dave and I once carried a bunch of amateur radio equipment up a Colorado peak in the middle of a brutally cold snowstorm. Video: https://youtu.be/g850RIQp6rA

    Thanks for the HIRF-6 link. That's unbelievable! Hope you are doing well.

    EDIT: woah. M0XER did 8 circumnavigations. That's unbelievable. I wonder if that is a record for a man-made, atmospheric object.
