performance. A large meter monitors the incoming signal level. Other features
include Volume, Squelch, and Transmit Indicator Light.
C.
TRANSMITTER
The heart of your H407 is the all new PLL oscillator. It provides full 40 channel
operation from only one crystal. Integrated circuits plus other components replace
the balance of crystal. PLL is the most accurate frequency system available for CB,
