ATTACHING THE MICROPHONE HOLDER

You can connect the microphone hold- er to the right side of the transceiver or to another location in your vehicle.

To attach the holder to the transceiver, secure it with the supplied mounting screws and lockwashers.

3.Attach the holder at the mounting location using the supplied mount- ing screws, lockwashers, wash- ers, and nuts.

To attach the holder to another loca- tion in the vehicle, such as the dash- board, follow these steps.

1.Using the holder as a template, mark the positions for the mount- ing screw holes at the desired location.

2.At each marked position, drill a hole slightly smaller than the sup- plied mounting screws.

Caution: Be careful not to drill into anything behind the mount- ing surface.

MOUNTING THE TRC-442

The most common mounting location for this CB is under a vehicle’s dash- board. However, if you use the TRC- 442 as a base station, you can place it on a desk, shelf, or table. See “Using the CB as a Base Station” on Page 9.

If you are mounting the CB in a vehi- cle, choose a location where:

•You can easily reach the CB.

•Wires and cables are clear of the vehicle’s pedals or other moving parts.

•The CB is not directly in front of heating vents.

•All wires and cables can reach their connection points.

TRC-442 specifications

The Radio Shack TRC-442 is a classic CB (Citizens Band) radio widely recognized for its impressive features and user-friendly design. Launched in the 1980s, the TRC-442 became a popular choice among enthusiasts and casual users alike, thanks to its reliability and performance.

One of the standout features of the TRC-442 is its compact and portable design, making it a perfect fit for both mobile use in vehicles and as a base station at home. The radio operates on the standard 40 CB channels, offering users a range of communication options. With a power output of approximately 4 watts, it provides a solid transmission range, enabling users to communicate with other CB operators over considerable distances.

The radio includes a built-in microphone for hands-free operation and a large, easy-to-read display that shows channel numbers and signal strength. This thoughtful design ensures that users can quickly identify their settings at a glance, enhancing usability. The TRC-442 also features an external speaker jack, allowing users to connect an external speaker for improved audio clarity, particularly beneficial in noisy environments.

The ANL helps minimize background noise, providing clearer audio during transmission and reception. The adjustable squelch control allows users to eliminate unwanted static or noise, ensuring a more enjoyable listening experience.

Another key characteristic of the TRC-442 is its versatility with various transmission modes. It supports AM (Amplitude Modulation) and SSB (Single Sideband) transmission, allowing users to choose the mode that best suits their needs. While AM is the standard for most CB communications, SSB offers increased range and efficiency, making it ideal for long-distance communication.

The TRC-442 also boasts a rugged construction, designed to endure the rigors of both outdoor and vehicular use. Its robust casing protects the internal components, ensuring durability over the years.

In summary, the Radio Shack TRC-442 stands out as a reliable and versatile CB radio.
