The Digital Evolution Continues

Lightweight & Compact Body

The Icom ID-51E has a compact 58×105.4×26.4 mm body, and weighs only 255g (approx.) with battery pack and antenna. In this slim body, the ID-51E contains 5W output power, VHF/UHF dual band, D-STAR and integrated GPS receiver.

V/V, U/U, V/U Dualwatch

V/V, U/U Dualwatch exampleThe dualwatch function monitors VHF/VHF, UHF/UHF and VHF/UHF bands simultaneously.* The audio and squelch levels can be set separately for the main and sub-bands.
* DV/DV, AM/AM, FM-N/FM-N and DV/FM-N modes dualwatch not available.

D-STAR DV Mode (Digital Voice + Data)

The D-STAR (Digital Smart Technology for Amateur Radio) DV mode is the leading amateur radio digital format.

DR (D-STAR Repeater) Mode Operation

DR Mode exampleThe DR (D-STAR repeater) mode operation allows you to connect to D-STAR repeaters and users more effortlessly. In this mode, just two simple steps are needed.

Icom ID-51E

Automatic Repeater List-up Function

Near repeater exampleUsing the GPS position information, the automatic repeater list-up function shows the list of nearby D-STAR repeaters from the memory* and helps you quickly access the nearby D-STAR repeater.
* To use the automatic repeater list-up function, the position data of the repeater is required. The ID-51E will be shipped with D-STAR repeater memories preprogrammed, but the position data of some D-STAR repeaters may not be available.

Independent AM/FM Receiver

Broadcast radio exampleFM and AM broadcast stations can be listened to while using the dualwatch function for monitoring ham bands. When a ham band signal is received, the broadcast station is automatically muted.

Voice Memory Function*

Voice recorder exampleThe QSO recorder function records incoming and outgoing calls. The voice recorder function can record an off-line conversation. The recorded voice message can be transmitted repeatedly. (Up to 60 seconds × 1 channel)
* microSD card required.

microSD Card Slot

When used with a microSD card (Up to 32GB), the microSD card can store various contents including voice memory, DV auto reply message, TX voice message, QSO log, RX history log and GPS log data. Memory channels, D-STAR repeater memories and other personal settings can be saved to the microSD card and can be loaded to the ID-51E transceiver.

SPEECH Function

The SPEECH function announces the received call sign (DV Mode), operating frequency, and/or mode. (Depends on users settings.)

Integrated GPS Receiver

GPS receiver transparent imageThe integrated GPS receiver provides fast start-up time and accurate position. Your current position and altitude are shown on the display and offers a position reporting function in DV mode. The GPS-A mode assists in easy D-PRS operation.

Icom ID-51E

Automatic Reply Function (DV Mode)

When receiving a call addressed to your call sign, the ID-51E can automatically reply your current position information*. Between ID-51E’s communication, replied position information can pop up on the caller’s display.
* Function not available on all D-STAR networks.

GPS Log Function*

The GPS log function logs your position information at regular intervals (1 second–60 seconds, depending on the setting) and memorizes this in the microSD card to export to your PC. The GPS logger only mode turns on the GPS logger function with the radio in sleep mode.
* microSD card required.

IPX7 Waterproof Construction

The ID-51E has superior IPX7 waterproof protection(1m depth of water for 30 minutes). It can be used in harsh outdoor environments, when hiking, mountain biking, touring and mountain sports.

Menu-Driven User Interface

The directional keypad and quick menu button help you with quick and intuitive access to many settings and speeds up the operation. The large full dot-matrix display with easy-to-read characters increases the amount of information.

5W Output Power

Using a highly-effcient PA amplifier, theIcom ID-51E generates 5W of RF output power from this compact body.

Long Lasting Battery Pack

The supplied BP-271 provides up to 4.5 hours* of operating time, and the optional large capacity battery pack, BP-272 provides up to 7.5 hours*.
* Typical operation with 1:1:8 duty cycle in DV mode. (Power save ON.)

Direct Rapid Charging

Recharge the ID-51E by plugging the supplied wall charger directly in the radio. The BP-271 can be charged in 3 hours (approx.) when the power is OFF.

CS-51 Cloning Software Supplied

The CS-51 cloning software is supplied with the ID-51E for editing various memory settings from a PC. (Supplied with the application CD)
