Simple Transistor Balloon Payload Transmitter Board Version 1. It is a “Modernized” Project #27 from 103 Simple Transistor Circuits ©1964 using NPN Si Transistors vs. the original’s PNP Ge transistors. This was originally intended to be a balloon payload that transmits temperature info on the 11-meter or 10-meter bands. For scale the battery holder is a AAA cell.
