Your REALISTIC TRC-458 is a completely solid-state AM/SSB Transceiver tor Class "D" 27 MHz Citizens Band use. It uses a frequency synthesizing circuit with Digital Phase Locked Loop techniques to provide crystal controlled transmit and receive operation on all 40 channels. The PLL circuitry assures ultra-precise frequency control. You can use your TRC-458 Transceiver on any one of the 40 channels in the conventional AM mode, plus the same 40 channels in either the Upper Single Sideband mode or the Lower Single Sideband mode.
This flexibility not only doubles the effective number of channels from 40 to 80, but SSB also increases the effective range of communication because all the power is concentrated in one sideband to provide 100% talk-power. Single Sideband reception also adds advantages in sensitivity and selectivity, plus lower signal to noise. This of course also contributes to an increase in operating range.
The TRC-458 has been carefully designed for ease of operation. You can select AM, Upper Sideband or Lower Sideband with the simple change of a 3 position switch. Transmission is simple too just the microphone button. Ord nari y an SSB signal will reach farther and be hoard more clearly that i equivalent AM signal SSB reception is simple-just adjust the CLARIFIER control to bring in the voice transmissions.
We've added all the other most wanted features for optimum communications RF Gain control. Squelch, Clarifier, PA, switchable Automatic Noise Limiter and Noise Blanker circuits, RF S meter and Crystal Lattice Filter.
The TRC-458 is designed to operate from 12 volt DC negative or positive ground electrical systems, or from 120 Volt AC power.
