SUPER STAR 2400 MOBILE TRANSCEIVER 5-Mode
AM/FM/USB/LSB/CW

The Super Star 2400 is a combination transmitter-receiver designed primarily for mobile use, It employs the very latest technology to provide 240 channels of operation by means of digital frequency synthesis with PLL PLL02A (phase-locked-loop) circuitry. The use of PLL assures a precise on-frequency operation on every channel in both transmit and receive mode. The Super Star 2400 also includes many other features which will provide greater operating convenience and assure optimum communications under a wide range of conditions.

Super Star 2400 CB Radio

  • Operable on 240 channels divided into six groups of 40 channels.
  • 2-way RF gain switch.
  • Full noise reduction features - ANL and noise blanker.
  • 5 modes of operation - CW, LSB, USB, AM or FM selectable with a rotary switch.
  • Provision of PA.
  • Concentrically mounted fine and coarse controls to fine tune to any transmissions or operate in interchannel frequencies.
  • Tone switch to select receive tonal quality in 2-way.
  • RF power output switchable in 2-way for required communication range.
  • TX lamp that indicates you are on-the-air.
  • External speaker jack for an extra sound source.
  • Electrically floating chassis for negative or positive ground operation without switching.
  • A high-sensitivity dynamic microphone equipped.

PLL02A CB Radio

Overview

This PLL-circuit use a 9 bit BCD binary programmable divide-by-N counter.

Down-converting of the frequency to the divider

PLL02A CB Radio This PLL circuit use a mixer and a XTAL oscillator to convert the output frequency f OUT to the f IN to the PLL Circuit.
The XTAL frequency is f XTAL = f OUT - f IN




The output frequency can be changed by changing the mixing-XTAL or add a new mixing-XTAL to the oscillator. PLL02A CB Radio
