The Radioddity GD-88 DMR/Analog is a dual-band handheld radio built for ham radio enthusiasts who demand high performance, robust features, and flexibility. Offering a maximum output of 7 watts, cross-band repeat, and GPS/APRS support.
The GD-88 stands out as a powerful all-in-one communication tool. It merges both traditional analog FM and modern digital DMR modes into a single, easy-to-use device that performs reliably in both urban and remote environments.
Analog and Digital Operation
The GD-88 operates in both analog and digital (DMR Tier I & II) modes, allowing seamless communication across a wide range of systems. This dual-mode support means users can interact with traditional analog repeaters while also enjoying the clarity and advanced features of DMR.
Moreover, switching between modes is simple and programmable, which makes adapting to different communication scenarios fast and intuitive.
VHF and UHF Dual-Band Coverage
This radio supports both VHF (136–174 MHz) and UHF (400–480 MHz) frequency bands. VHF is ideal for outdoor or rural communication due to its longer wavelength and better range over open terrain. In contrast, UHF performs well in urban settings with buildings and obstructions. Consequently, the GD-88 is perfect for varied environments, whether you’re hiking, driving, or operating at home.
High Output Power
With up to 7 watts of power output, the GD-88 ensures strong signal penetration and extended range. Users can also adjust power levels depending on the situation, conserving battery life when full power isn’t necessary. This flexibility allows better performance control whether you’re operating nearby or across challenging terrain.
GPS and APRS Capability
The integrated GPS module enables real-time location tracking. It supports APRS (Automatic Packet Reporting System) in both analog and digital formats, which allows users to transmit their position data, messages, and telemetry. This is particularly useful during group activities, public service events, or emergency situations where situational awareness matters.
Cross-Band Repeater Function
One of the standout features of the GD-88 is its full cross-band repeater capability. This function enables the radio to receive a signal on one band and retransmit it on another. As a result, users can extend the range of handheld radios or link different bands together. This feature makes the GD-88 more versatile than most standard handhelds.
Single Frequency Repeater (SFR)
In addition to cross-band repeat, the GD-88 supports SFR (Single Frequency Repeater) in digital mode. It listens and transmits on the same frequency using time slot switching. This is especially beneficial in DMR, where the radio receives on Time Slot 1 and transmits on Time Slot 2 (or vice versa). Consequently, users can create a mini repeater setup without the need for a duplexer.
Dual Display and Dual Standby
The color LCD screen offers a clear, readable interface with real-time display of frequency, mode, signal strength, GPS data, and battery status. Meanwhile, dual standby mode allows the user to monitor two frequencies or channels at once, making multitasking and scanning far more efficient during operations.
Extensive Contact and Channel Capacity
The Radioddity GD-88 DMR/Analog supports up to 300,000 digital contacts and 4,000 channels, ensuring compatibility with large DMR networks like BrandMeister. Furthermore, it can store multiple zones, groups, and scan lists, allowing for highly organized communication.
Battery Life and Charging
Equipped with a 3100mAh rechargeable battery, the GD-88 provides long operational time, even with GPS and high-power use. Charging is done via a desktop cradle or direct connection, and the battery supports extended usage—ideal for long outings, emergency operations, or full-day events.
Additional Features
- Voice Prompting: Helps navigate menus without looking at the display
- DTMF, 2-Tone, and 5-Tone Signaling: Offers compatibility with paging and analog systems
- Customizable Buttons: Allows quick access to functions like power level, scan, or zone switching
- Digital Encryption: Supports basic encryption for private communications
- Keyboard Lock and Emergency Alarm: Enhances safety and prevents accidental changes
Performance and Audio
The audio quality of the GD-88 is crisp and clear in both analog and digital modes. Thanks to DMR’s noise suppression and error correction, even weak signals can be heard clearly. The speaker provides strong volume, while external accessories can be used for hands-free operation or improved audio output.
