A Two-Transistor FM Broadcast Band Tuner for a 12-Volt Automobile System
Commercial FM broadcast-band vacuum-tube receivers have been with us for many years. Generally they have been of the relatively expensive, high-fidelity, entertainment type. However, with the advent of competitive transistors having VHF capabilities, the FM receiver market has been considerably expanded. Our country alone saw the birth of 173 new FM transmitting stations in the last sixteen months. The total number of FM stations broadcasting as of the end of April of this year was 988. It is expected that this growth of FM will be accelerated due to the over-crowding of the AM spectrum and FCC approval of multiplex stereo.
