MOUNTING THE MICROPHONE HOLDER

Using a Philips screwdriver and the sup- plied screw and washers, attach the supplied microphone holder to the CB's left or right side, either horizontally or vertically (depending on how you plan to use it).

MOUNTING THE TRC-446

The most common mounting location for this CB is under a vehicle’s dashboard. If you use the TRC-446 as a base sta- tion, you can place it on a desk, shelf, or table (See “Using the CB as a Base Sta- tion” on Page 8).

When mounting the CB in a vehicle, choose a location where:

you can easily reach the CB

wires and cables are routed away from the vehicle's pedals or other moving parts

all wires and cables can reach their connection points

the CB is not directly in front of heat- ing vents

Cautions:

If you use the TRC-446 in a vehicle, mount it securely to avoid damage to the CB or vehicle or injury to any- one in the vehicle during sudden starts or stops.

Do not mount the CB where it could damage or interfere with the proper operation of any passive restraint safety device (an air bag or seat belt).

Follow these steps to mount the CB us- ing the supplied hardware.

1.Select a location that provides secure mounting.

Caution: Be careful not to drill into anything behind the mounting sur- face.

2.Using the slots in the mounting bracket as a template, mark the positions for the screw holes.

3.In each marked location, drill a hole slightly smaller than the supplied mounting screws.

TRC-446 specifications

The Radio Shack TRC-446 is a classic handheld CB (Citizens Band) radio, well-regarded in the realm of two-way communication devices. Released in the 1980s, it has become a sought-after collector's item due to its impressive features, build quality, and ease of use.

One of the defining characteristics of the TRC-446 is its compact and portable design. Weighing less than many of its contemporaries, it fits comfortably in the hand and is lightweight enough for prolonged use. This makes it an excellent choice for outdoor enthusiasts, truck drivers, and hobbyists alike. Its robust construction ensures that it can withstand the rigors of daily use.

In terms of technology, the TRC-446 operates on the standard 40 channels designated for CB radios in the United States, allowing users to communicate over short distances. It incorporates AM modulation, which was the primary mode of communication for CB radios, ensuring compatibility with a wide range of other devices. The operating range can reach several miles, depending on the terrain, making it ideal for both urban and rural communication.

The user interface is designed for simplicity, featuring a clear display with channel indicators, an easy-to-access volume control, and a squelch knob to eliminate background noise. The push-to-talk button is conveniently placed, providing seamless access during conversations. Additionally, the TRC-446 comes equipped with a built-in microphone, making voice transmission effortless.

Another noteworthy feature is the external antenna jack, which allows for improved communication range. Users can connect various antennas, enhancing their ability to send and receive signals in challenging environments.

The TRC-446 also supports compatibility with additional accessories, such as handsets and speakers, allowing for a more customizable communication experience. The battery life is decent for a handheld device, with options for both rechargeable and disposable batteries, making it versatile for different use cases.

In conclusion, the Radio Shack TRC-446 represents a significant piece of communication technology from the late 20th century.
