Page 2: Section 1 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. -
Page 3: Section 2 Installation & Initial Adjustment
POWER CONNECTION The SIMBA SSB is constructed to be used in vehicles using either negative or positive ground. The red power lead is to be connected to the positive terminal of the battery. The black lead is the Negative Lead. If the existing wiring is used be sure that it is heavy enough to prevent voltage drop to the radio. -

TYPICAL AUTOMOBILE INSTALLATION MOBILE INSTALLATION Your SIMBA SSB has been adjusted at the factory to give optimum performance using a 52-ohm antenna. There are a number of 52-ohm antennas available for mobile citizens band use. For an automobile installation, a whip may be used with good efficiency because the automobile acts as a counterpoise and reduces detuning effects. -

SWR is obtained. For The built-in SWR bridge is ideal for this type of adjustment. The SIMBA SSB will work into an antenna system having an SWR as high as 3: 1. For best communications, you will want this figure as near I : I as possible so that the antenna will be operating at its best efficiency. -
Page 6: Section 3 Operating Instructions
When listening to a sideband signal on the proper mode, it may sound either too high pitched or too low pitched. The reason for this is that your receiver may not be tuned to the exact same frequency as the transmitter it is listening to. For this reason, SIMBA SSB is equipped with a Clarifier. - Page 7 SWR CALIBRATION CONTROL This control is installed to adjust the calibration of SWR meter. Connect antenna, and turn on the power switch. Then, press the microphone button and adjust CAL control so that the meter needle comes to "CAL" point. Push "CAL" button. Read the value on the meter.
