engineering. Designed for the Citizen Band Mobile operation, this compact
package is big in performance. It is a quality piece of electronic equipment,
skillfully constructed with the finest components. The circuitry is all a solid-
state, mounted on rugged printed circuit boards. It is designed for many years
of reliable, trouble-free performance.The night-light buttons allow the night
use.Your has a built Channel Phase-Locked Loop

synthesizer circuit.
The PLL circuit achieves a new technique for generating all the required
frequencies with fewer crystals. The result is much tighter frequency control
and superior reliability.
