Thanks to Mark for remembering the Microsat (AO-16 thru 19) Birthday.
For me personally, this project was really a Personal High Point!

We went from "light bulb turns on" concept to flight in just over 2
years. The concept of building a satellite with 5 stacked trays
interconnected with a standardized bus was really an innovation. All 4
satellites shared 4 (nearly) identical trays (TX, RX, Computer & Power)
and a 5th tray housing each group's unique hardware worked out very
well; the 5th module was dubbed "TSFR" (this space for rent!).

My personal contributions were the receiver modules (with help from
W4PUJ), the AART "glue" board that is in every module (with help from
Bob Stricklin, N5BRG) and the TSFR concept.

Bob McGwier (N4HY) has collected a lot of Microsat photos at

Happy 20th Birthday!
