Insures 24 w output over temperature range of -20 to +120°F. Zener diode voltage-regulating circuit prevents changes in collector supply voltage of oscillator Q1. Base-driven modulator Q2 may be fed from tape repeater preamp, microphone, or master control center serving induction radio system using roadside telephone-line loops.-E. A. Hanysz, J. E. Stevens, and A. Meduvsky, Communication System for Highway Traffic Control, Electronics, 33:42, p 81-83.
