Thesewords were not unusual at North Granby,Conn., during the 1955 ARRL Field Dayactivities. Concern over the weather wasquite reasonable considering that perhaps thefirst solar-powered amateur station was in opera-tion. Both the transmitter and receiver incor-porated transistors and were powered completelyby energy from the sun. Power Supply Power for the transmitter and receiver wasobtained from six self-generating selenium photo-electric cells. These were the International Rec- 1 Campbell, Transistorized Little Gem , QST, Aug., Solar-powered amateur station. Ihe solar batterycan be seen clamped to the top left of the operating transistor transmitter is in the center with thereceiver to the left.
