The Alinco DR-638T is a professional dual-band mobile radio designed for users who need high-power communication, flexible frequency coverage, and advanced signaling capabilities. Operating across VHF and UHF bands, the DR-638T provides up to 50W VHF and 40W UHF output, making it suitable for vehicle-based communication, base-station applications, field operations, and professional radio networks.

One of the key advantages of the DR-638T is its dual-band capability. It supports VHF and UHF operation while offering extensive memory capacity for organizing multiple frequencies and communication groups. The radio also features cross-band repeater functionality, allowing compatible configurations to relay communication between different bands and potentially extend coverage.

For monitoring applications, the DR-638T includes a wideband receiver with AM Airband reception from 108–136 MHz, allowing users to monitor aviation-related communications where legally permitted.

With a customizable multi-color display, detachable front panel, advanced signaling, voice compander, theft alarm, and multiple power levels, the Alinco DR-638T is a versatile communication platform for professional users.

Why Choose the Alinco DR-638T?

High-Power VHF & UHF Communication

The DR-638T provides selectable output power up to:

• VHF: 50W
• UHF: 40W

Lower power settings are also available, allowing operators to select an appropriate output level based on their communication requirements and power consumption.

Actual communication range depends on terrain, antenna system, installation height, interference, frequency, and other environmental conditions.

Dual-Band Operation

The Alinco DR-638T is designed to operate across both VHF and UHF bands.

Its specified transmit ranges include:

• VHF: 144–145 MHz
• UHF: 430–440 MHz

This makes the DR-638T suitable for communication systems that require flexibility between VHF and UHF.

Cross-Band Repeater Function

A major feature of the DR-638T is its cross-band repeater capability, which can allow the radio to relay communication between compatible VHF and UHF channels.

This can be useful when extending communication between handheld radios operating on different bands.

Note: Cross-band repeater functionality may require activation or appropriate configuration. Users should verify the specific unit’s available functions and ensure repeater operation complies with applicable radio-frequency regulations.

Wideband Receiver with AM Airband

The DR-638T is not limited to conventional VHF/UHF FM reception.

Its receiver includes:

• 108–136 MHz AM Airband
• 136–174 MHz
• 350–470 MHz

This makes the radio useful for monitoring a wider range of signals, including aviation communications in the supported AM receive range.

Important: Receiving and especially transmitting on aviation frequencies is subject to applicable regulations. The DR-638T’s Airband function is for reception/monitoring only within the specified range.

758 Memory Channels

The DR-638T provides up to 758 memory channels, giving operators substantial capacity for storing frequencies, communication groups, and different operating configurations.

This is particularly useful for professional users who manage multiple communication networks or frequently switch between different operating areas.

Flexible Power Selection

The DR-638T supports multiple output power levels.

Using the appropriate power level can help reduce unnecessary RF output and power consumption while maintaining suitable communication performance.

Advanced Signaling & Selective Calling

The radio supports multiple signaling systems for professional communication management, including:

• CTCSS
• DCS
• DTMF
• 2-Tone
• 5-Tone

These functions can be used for selective calling, group management, channel access control, and other compatible radio-network applications.

Clear Audio with Voice Compander

The integrated Voice Compander helps improve perceived voice clarity by reducing the impact of background noise and improving audio consistency.

This can be particularly useful in vehicle cabins, industrial locations, and other environments where background noise may interfere with radio communication.

Customizable Multi-Color Display

The DR-638T features a large backlit display with customizable illumination options.

The multi-color display helps users identify radio status and operating information quickly, particularly when operating the radio inside a vehicle at night.

Removable Front Panel

The radio’s front panel can be separated from the main unit for flexible installation.

With the appropriate separation cable, the control head can be positioned separately from the main radio body. This is useful for vehicle installations where dashboard space is limited.

Theft Alarm & Security Functions

The DR-638T includes a theft alarm function designed to provide an additional layer of protection for vehicle-installed equipment.

A password function is also available for supported security and configuration controls.
