Developed for unregulated 12-VDC supplies used by some amateurs with low-power VHF FM equipment, where no-load voltage may be 18 V or more. During transmit, voltage drops to about 12V, but on receive may exceed voltage ratings of small-signal transistors in transceiver. Use heatsinkwith transistor, and use 2-A fuse to protect transistor from shorted load.-J. Fisk, Circuits and Techniques, Ham Radio, June 1976, p 48-52.
