Donald earned his Technician Plus ticket back in 1991. He encouraged me to upgrade from Novice so that we could talk on two meters! All that we had were two HTs and we talked on the local repeater all the time. It was a great way to get to know each other and meet local hams.
We were also tennis partners in high school and grew into a pretty good doubles team.
It was a sad day when he took his life so long ago, but I will always remember my high school friend and his Yaesu hat that he wore constantly!
