GENERAL INFORMATION
DESCRIPTION
Your new PEARCE-SIMPSON SIMBA SSB is an all transistorized, 23-channel Citizens Band SSB/AM Transceiver. This radio is ideally suited for base
and/or mobile operation from 115V AC or 12.6V DC power source, either positive or negative ground. A 12V DC power cord, a 117V AC power cord and
mounting cradle are included with your SIMBA SSB. To provide the crystal-controlled, 23-channel operation, PEARCE-SIMPSON utilizes an
all-transistor HetroSync

circuit.
The receiver is a sensitive superheterodyne circuit featuring: Dual conversion, low noise RF stage, slide-o-tune, adjustable squelch, noise blanker,
external speaker jack, and instantaneous selection of any of the 23 crystal controlled channels.
The transmitter section is designed around highly reliable silicon transistors and the HetroSync

circuit. This circuit makes use of the output of three
crystal -controIled oscillators which are mixed together to produce the desired frequency. The transmitter final is a conservatively rated high gain RF
power transistor.
Both transmitter and receiver work on upper sideband or lower sideband.
