FINE/COARSE CONTROL : Allows variation of the receive operating frequency above or below the assigned frequency. Although this control is intended primarily to tune in SSB/CW signals, it may be used to optimize AM/FM signals as described in the Operating Procedure paragraphs.

  • Page 7: Procedure To Receive And Transmit

    PROCEDURE TO RECEIVE AND TRANSMIT A. MICROPHONE The receiver and transmitter are controlled by the push-to-talk switch on the microphone. Press the switch and the transmitter is activated, release switch to receive. When transmitting, hold the microphone two inches from the mouth and speak clearly in a normal voice. This transceiver comes complete with a low impedance dynamic microphone.

  • Page 8: Receiving Ssb Signals

    RECEIVING SSB SIGNALS There are four types of signals presently used for communications in the Citizens Band : FM, AM, USB and LSB. When the MODE switch on your unit is placed in the AM position, only standard double-side band and in FM position, only frequency deviation, full carrier signals will be detected.
  • Page 9 Once the desired SSB mode has been selected, frequency adjustment may be necessary in order to make the incoming signal intelligible. The FINE/COARSE control allows the operator to vary frequency above or below the exact frequency of the channel. If the sound of the incoming signal is high or low pitched, adjust the operation of the FINE/COARSE. Consider it as performing the same function as a phonograph speed control.

  • Page 10: Alternate Microphones And Installation

    ALTERNATE MICROPHONES AND INSTALLATION For best results, the user should select a low-impedance dynamic type microphone or a transistorized microphone. Transistorized type microphones have low output impedance characteristics. The microphones must be provided with a four-lead cable. The audio conductor and its shielded lead comprise two of the leads. The third lead is for transmit control and fourth is for receiving control.
  • Page 11 the connections. Keep the exposed wire lengths to a minimum to avoid shorting when the microphone plug is reassembled. Fig. 2 Microphone plug wiring To wire the microphone cable to the plug provided, proceed as follows : 1. Remove the retaining screw. 2.
  • Page 12 Fig. 3 Microphone plug pin numbers viewed from rear of pin receptacle. 6. Be sure that the housing and the knurled ring of Figure 2 are pushed back onto the microphone cable before starting to solder. If the washer is not captive to the pin receptacle body, make sure that it is placed on the threaded portion of the pin receptacle body before soldering.
  • Page 13 CIRCUIT DESCRIPTION CHAPTER 3 3.0 INTRODUCTION This section explains the technical theory of operation for the SS－158 EDX mobile AMATEUR radio. 3.1 PLL CIRCUIT The Phase Lock Loop (PLL) circuit is responsible for developing the receiver’s first local oscillator signal and the transmitter’s exciter signal. The PLL circuit consists primarily of IC2, IC3, IC4, IC5, Q25, Q27, Q28 and Q29.
  • Page 14 3.4 TRANSMITTER AMPLIFIER CIRCUIT The transmitter takes the basic exciter signal from IC9 of the TX mixer and amplifies it through a series of amplifiers consisting of Q52, Q51, Q49 ,Q47and Q48 where it is sent out to the antenna connector.
