I will be at the Everett Sr. High School with 15 - 20 Physic students and their teacher to demonstrate the concept of Amateur Radio using a satellite - AO-91.    It's near the end of the school year and the teacher will be doing hands-on project which include a balloon launch with a smart package that will tell GPS, temperature, direction using APRS.     I will be setting up my tripod with a PA system for work as many of you as I can. Wednesday Jun 5 at 12:29 (PDT) 1929 UTC from Grid CN87.  (I know, not the most rare grid).   We will be on the front lawn of the school. I hope we can demonstrate how well we can exchange calls and grids in the shot time it's over us. Any suggestion, please email me offline

Thank you John Van DalenN7AME
