During the 1994-1995 school year I hooked up my first “laptop” to a VHF mobile rig and used it to send and receive packet radio messages on behalf of my fourth and fifth grade students. We were on the second floor of a 2-story school building, and the antenna was mounted on top of the building’s flat roof. This early portable weighed 16 pounds and even had a hard drive! Oh, it also had an internal battery and could run without an external power supply plugged in. Not for long, though! This all took place before I ever even heard about the Internet. Things certainly have changed in the past 32 years!
