This can be especially useful when:
- 🚙 Travelling in a 4WD convoy
- 🚚 Receiving directions from another vehicle
- 🏗️ Working around noisy machinery
- 🚜 Operating agricultural equipment
- 🛣️ Receiving important road or traffic information
- 🔊 Cabin noise makes a transmission difficult to hear
Rather than immediately asking another user to repeat their message, Instant Replay gives you the ability to listen again.
🎙️ EVERYTHING YOU NEED ON THE CONTROLLER MICROPHONE
The UHF390R eliminates the need for a separate dashboard-mounted control head by integrating the radio controls into the heavy-duty microphone.
The controller microphone incorporates:
- 🖥️ Large LCD display
- 🎛️ Radio controls
- 🔊 Built-in speaker
- 🎙️ Push-to-talk functionality
This means the transceiver itself can be installed out of sight while the microphone remains the primary user interface.
🚙 IDEAL FOR MODERN VEHICLES WITH LIMITED DASH SPACE
Modern dashboards often leave little room for a conventional full-size UHF radio.
The UHF390R solves this problem by using a micro-size transceiver measuring only:
Height: 27mm
Width: 102mm
Depth: 85mm
The compact transceiver can potentially be installed:
- 🚙 Under the dashboard
- 💺 Beneath a seat
- 🧰 Behind suitable interior trim
- 🚐 Inside a compatible console
- 🛻 In other protected concealed mounting locations
The controller microphone then keeps the display, audio and everyday controls within convenient reach.
🔊 DUAL SPEAKER AUDIO
The UHF390R incorporates speakers in both:
- 🎙️ Controller microphone
- 📻 Transceiver body
This dual-speaker arrangement is designed to provide excellent sound quality and useful audio volume in the vehicle cabin.
Maximum receiver audio output is listed at 3 Watts.
📻 FULL 5 WATT RF TRANSMIT POWER
Maximum RF Output Power: 5 Watts
Despite the compact transceiver design, the UHF390R delivers full-power UHF CB transmission capability.
When combined with an appropriately selected and installed 50-ohm UHF antenna system, it provides a capable communications setup for 4WD touring, convoys, commercial vehicles and general UHF CB use.
⚠️ Actual communication range depends heavily on antenna selection, antenna location, terrain, buildings, surrounding vehicles and whether direct or repeater operation is being used.
📶 DUPLEX REPEATER OPERATION
The UHF390R supports both simplex and repeater operation.
Repeater TX Offset: +750kHz
Where a compatible UHF CB repeater is available, duplex operation can extend practical communication coverage beyond direct vehicle-to-vehicle range.
⚠️ Duplex operation only provides a range advantage where an appropriate repeater is accessible. It does not automatically increase direct radio-to-radio range.
🔍 OPEN & PRIORITY SCANNING
The UHF390R includes both open and priority scan functions.
This allows the radio to monitor UHF CB channel activity automatically rather than requiring the operator to manually change channels.
Scanning Speed: Approximately 150ms Per Channel
A dedicated priority-channel function is also provided.

The UHF390R incorporates:
38 CTCSS Codes
104 DCS Codes
These signalling options allow compatible radios to filter unwanted received audio from other users sharing the same UHF CB channel.
⚠️ CTCSS and DCS do not make a channel private or encrypted. Other users can still monitor or transmit on the underlying UHF CB channel.
🎙️ AUTOMATIC LEVEL CONTROL – ALC
Automatic Level Control helps maintain consistent transmitted audio levels.
This can improve communication where microphone distance or the speaking volume of different users varies during normal operation.
🔌 TWO MICROPHONE EXTENSION CABLES INCLUDED
The UHF390R includes two microphone extension cables to provide greater flexibility when positioning the hidden transceiver and controller microphone.
One of these cables is designed for use with a pass-through connector.
