To disconnect the microphone from the CB, unscrew the locking nut then pull out the plug.

Caution: Never pull on the micro- phone’s cable.

CONNECTING AN

ANTENNA

There are many different types of CB antennas for mobile CBs. Each antenna type has its own benefits, so choose the one that best meets your needs. Your local RadioShack store sells a wide vari- ety of antennas.

Note: If you are using this CB as a base station, see “Using the CB as a Base Station” on Page 7.

When you choose an antenna, keep in mind that for the best performance you should mount the antenna:

•as high as possible on the vehicle

•as far as possible from sources of electrical noise

•vertically

Once you choose an antenna, follow its mounting instructions. Then route the

cable to the CB and connect the cable to the ANT. jack on the back of the CB.

Cautions:

•Avoid routing the cable next to sharp edges or moving parts, which might damage the cable.

•Do not run the cable next to power cables or other radio antenna ca- bles.

•Do not run the cable through the en- gine compartment or other areas that produce extreme heat.

For maximum range, adjust the anten- na’s Standing Wave Ratio (SWR) using an SWR meter (not supplied).

Follow the instructions supplied with the SWR meter and antenna to adjust your antenna’s SWR to the lowest possible value. SWR values of 2.0:1 are general- ly acceptable, with readings of 1.5:1 or lower being more desirable.

TRC-519 specifications

The Radio Shack TRC-519, released in the 1980s, is notable for its dual functionality, serving as both a base station and a handheld CB radio. This versatile piece of technology was designed for enthusiasts and everyday users alike, delivering reliable communication in an era when citizen band (CB) radios were gaining popularity.

One of the key features of the TRC-519 is its 40-channel capability, allowing users to access a wide range of frequencies. This flexibility was crucial for communication across different regions, making it a popular choice among truckers and road travelers who needed constant connectivity. The unit also features a good quality built-in speaker and a high-sensitivity microphone, ensuring clear and effective communication.

The TRC-519 operates on the AM modulation, a standard for many CB radios during that period. This technology provided users with a strong and reliable audio signal. Additionally, the radio is designed with an instant channel selection feature, allowing users to quickly switch frequencies without delay. This is particularly useful in dynamic situations where swift communication is essential.

Another distinguishing characteristic of the TRC-519 is its robust construction, which contributes to its durability. The radio's design features a compact form factor and a user-friendly interface, making it suitable for both novice and experienced users. The knobs and buttons are intuitively placed, ensuring ease of use even in demanding environments.

The radio is powered by a standard 12-volt system, which is common for automotive use, making it easy to integrate into vehicles. Its versatility extends to both mobile and stationary use, providing users the flexibility to communicate from various locations.

Overall, the Radio Shack TRC-519 combines essential features, rugged design, and practical technology, making it a reliable choice for those in need of effective communication. Whether for leisure, work, or emergency situations, the TRC-519 represents an important chapter in the history of radio technology, paving the way for modern communication devices. With its timeless functionality, it remains a sought-after item among vintage technology enthusiasts and collectors today.
