In my last video I assembled a "mini-array" for amateur radio satellites. I used two Arrow II antennas phased together for circular polarization, mounted on a Yaesu G-5400 az-el rotator. Today we build the controllers to steer the antennas, finish the station assembly, and get on the air for our first QSOs with the new setup.
Check out "The Radio Artesian" K3NG's website for more details and source code for the rotator controller.
