Key Features and Benefits

Packed with an array of advanced features, the PC78LTX offers a versatile and powerful CB radio experience. Here are some of those features that set it apart from the competition:

  1. Integrated SWR Meter with High SWR Warning LED: The Uniden PC78LTX comes equipped with an integrated SWR (Standing Wave Ratio) meter, allowing users to easily tune their antenna system for optimal performance. This feature ensures efficient power transmission and reception, reducing signal loss and interference. The addition of a high SWR warning LED further enhances the user experience by providing a visual indicator when the SWR values exceed safe levels, helping users avoid potential damage to their equipment.
  2. RF Gain Control: The RF (Radio Frequency) gain control is a crucial feature that lets users adjust the sensitivity of the receiver. This control allows users to fine-tune their reception to adapt to different signal strengths and conditions. Whether communicating over long distances or dealing with weak signals, the RF gain control ensures clear and consistent reception, minimizing unwanted noise and interference.
  3. Noise Blanker and Automatic Noise Limiter: The PC78LTX is equipped with a Noise Blanker and an Automatic Noise Limiter (ANL) feature. The Noise Blanker effectively reduces pulse-type interference, such as ignition noise from vehicles, while the ANL feature suppresses continuous background noise. This combination ensures that communication remains clear and intelligible even in noisy environments, enhancing the overall communication quality.
  4. Instant Channel 9 Switch: For emergency situations and quick access to critical information, the PC78LTX offers an instant Channel 9 switch. Channel 9 is the dedicated emergency channel in the CB radio band, used for distress calls and urgent communication. With this feature, users can swiftly switch to Channel 9, ensuring rapid response and assistance when needed.
  5. PA (Public Address) Functionality: The Public Address (PA) feature allows users to utilize their CB radio as a powerful external speaker system. This function is particularly useful for communicating with individuals outside the vehicle or addressing a group of people. Whether you’re making announcements at a convoy stop or projecting your voice at an event, the PA functionality of the PC78LTX adds an extra layer of versatility to your communication setup.

What’s in the Box

You’ll also find a mounting bracket kit, microphone bracket, DC power cord, microphone and user manual.


These are basically the same radio with the PC78LTXFM enjoying the benefit of FM mode.

To accommodate the need for an AM / FM switch, Uniden have placed it where the Hi-cut switch was located. This feature has now been moved down to one of the five rotary controls. To accommodate this without losing any functionality the volume and squelch have been merged into a dual concentric pot – much like the PC68LTX does to save space.

What’s Great

Sturdy and Durable Build: The PC78LTX boasts a remarkable physical build, exuding durability from every angle. The radio’s rugged construction ensures it can withstand the rigors of various environments, making it a reliable companion for both off-road adventures and everyday use.

Quality Display and Controls: The display on the PC78LTX offers excellent clarity, presenting essential information clearly even in varying lighting conditions. The buttons and knobs have a satisfying tactile feel, allowing for precise adjustments and quick access to functions without fumbling.

User-Friendly Interface: Despite the wealth of controls on the front panel, the PC78LTX remains remarkably easy to use. The layout is intuitive, ensuring that even beginners can quickly grasp the radio’s functions. This ease of use eliminates any steep learning curve, making it accessible to CB novices.

Built-in SWR Meter: The built-in SWR meter is a standout feature, simplifying the process of tuning your antenna for optimal performance. This practical addition saves users time and effort, ensuring a clear and reliable signal without requiring additional equipment.

FM mode on the PC78LTXFM: This revised version of the radio includes FM mode for much clearer local communication.

What’s Not So Great

Lacks Single Sideband (SSB): One notable downside to the PC78LTX is its lack of Single Sideband functionality. SSB is favored by many CB enthusiasts for its enhanced range and audio quality, making its absence a limitation for those who require this feature.

Verdict / Bottom Line

The Uniden PC78LTX CB radio emerges as a compelling choice for communication enthusiasts seeking a blend of durability, functionality, and user-friendliness. Its solid physical construction instills confidence that it is built to last.

The radio’s impressive display and well-designed controls further enhance its appeal, offering a seamless user experience that caters to both seasoned CB veterans and newcomers. The intuitive interface and tactile buttons empower users to navigate its myriad features effortlessly, without feeling overwhelmed by the abundance of controls on the front panel.

One of the standout attributes of the PC78LTX is its integrated SWR meter, which streamlines the process of optimizing antenna performance. This thoughtful inclusion saves users time and effort, allowing them to focus on communication without the hassle of additional equipment.

While the PC78LTX boasts an array of pros, it’s important to address the notable absence of Single Sideband (SSB) functionality as a potential limitation. For those who require the extended range and audio quality that SSB offers, this omission might be a determining factor in their decision-making process. However, the inclusion of FM on the PC78LTXFM is a welcome addition now that FM mode is legal.

In the grand scheme of things, the Uniden PC78LTX CB radio excels as a reliable and user-centric communication tool that caters to a wide audience. Its durable construction, user-friendly interface, and added conveniences make it a noteworthy contender in the world of CB radios. For those seeking an all-around performer with an emphasis on build quality and ease of use, the PC78LTX presents a compelling option that bridges the gap between functionality and approachability.
