DUAL BAND, DUAL MODE, DUAL STANDBY

The GD-88 contains two independent VFOs that allow dual-band operation on VHF and UHF channels. With dual mode, the GD-88 allows a smooth transition from communication with conventional analog radios to digital DMR (Tier II) at any time. It also comes with dual-standby to monitor two channels at the same time.

The Radioddity GD-88 is a powerful handheld radio with a compact design, featuring selectable output power of 7W/2.5W and storage for up to 300,000 DMR contacts, which can be bulk imported via software.

◆ FCC ID: 2AN62-GD88
◆ Disclaimer: No License is required to purchase this radio, nor to Monitor (listen) to the many Amateur (Ham) Radio frequencies. However, an FCC License is required to Transmit (Talk) on Amateur Radio Frequencies in the USA. Please visit http://wireless.fcc.gov/services/amateur/licensing to learn more.

CROSS-BAND REPEATER FUNCTION

Working as a base radio to extend your talking range, the GD-88 is capable of transmitting on one frequency band (UHF/VHF) a receive a signal on the other frequency band (VHF/UHF). Compared to traditional cross-band repeaters, the GD-88 can cross-band repeat from an analog band to a digital one (or from digital to analog.)

SAME FREQUENCY REPEATER (SFR)

Using just one frequency for transmitting and receiving gives it full use of the DMR TDMA-technique by using one timeslot for receiving and transmitting the received signal on the same frequency, but using the second timeslot, acting as a Same-Frequency-Repeater (SFR). Multiple GD-88’s within a certain area can create a mesh-network, allowing single-VFO radios to communicate with other radios bridged by several GD-88’s that are operating in SFR-mode. The GD-88 is must-have radio for emergency situations where conventional communication systems are limited or unavailable.

GPS with APRS Function

The GD-88 has a powerful built-in GPS receiver for use with APRS to allow real-time push messages of position beacons to the APRS-network. This makes it ideal for outdoor activities where you need to be tracked by others, especially emergency situations.

3000MAH BATTERY & POWER SAVING

With its powerful 3000mAh battery and the built-in power saving feature, the Radioddity GD-88 supports up to 48 hours of standby time, 15 hours of continuous working time under the analog mode, and 23 hours under digital mode.

2-IN-1 DESKTOP CHARGER

The GD-88 comes with a unique desktop charger, allowing you to charge your radio and an extra battery (not included) at the same time.

FOUR CUSTOMIZABLE KEYS

The 2 side buttons above and below the PTT-key, the orange emergency button at the top, and the green key above the numerical keypad are customizable each with long/short press options. You can set different functions according to your needs such as High/Low Power, Backlight On/Off, Keylock On/Off, VOX On/Off, Select Zone, Scan On/Off, Scan Mode, Repeater/Talk Around, and many more functions.

CRYSTAL CLEAR SOUND

A Built-in 36mm diameter large speaker utilizes advanced voice processing technology to ensure a crystal-clear sound even in a noisy environment.

IP54 WATERPROOF

The GD-88 will be protected against contamination from limited amounts of dust and other particles. Additionally, you can be confident that it will be protected from water sprays from all directions.
