A dual-band (2 m/70 cm) analog and DMR digital handheld with selectable 7 W / 2.5 W output DMR Tier I and Tier II, with storage for up to 300,000 digital contacts Dual VFO with dual transmit and dual standby - monitor and work two channels at once Built-in GPS with full APRS: digital APRS over DMR and analog APRS at 1200 baud Cross-band repeat (CBR), including analog-to-digital or digital-to-analog, plus Same-Frequency Repeat (SFR) Large 3000 mAh battery for long operating time USB programming, well supported by Radioddity's software
Strengths

A lot of DMR handheld for the money: full 7 W on both bands, genuine dual-VFO/dual-watch operation (unusual on DMR HTs), a 300,000-contact database, built-in GPS with both digital and analog APRS, and flexible cross-band and same-frequency repeat that can even bridge analog and digital. The big 3000 mAh battery lasts well.

Weaknesses

DMR has a learning curve (code plugs, talkgroups, color codes) that newcomers find steep, the menu and software take some getting used to, and as a feature-dense Chinese HT the ergonomics and audio are functional rather than refined. Repeater functions and APRS setup reward patience.

Verdict

The Radioddity GD-88 is one of the more capable mid-priced DMR handhelds, standing out with true dual-VFO dual-watch, 7 W output, GPS/APRS in both digital and analog, and versatile cross-band/same-frequency repeat. It suits operators who want a do-it-all digital HT and do not mind DMR's complexity; analog-only users or first-time buyers may prefer a simpler radio.

The Radioddity GD-88 is a dual-band handheld that works both analog FM and digital DMR, and it packs an unusually full feature set for its mid-range price. It puts out up to 7 watts (switchable to 2.5) on both 2 meters and 70 centimeters, supports DMR Tier I and Tier II, and can store a huge 300,000-entry digital contact list - enough for the worldwide DMR user database.

Its standout trait among DMR handhelds is genuine dual-VFO operation: two independent VFOs give true dual transmit and dual standby, so you can monitor and work two channels at once, something many DMR HTs cannot do. A built-in GPS enables full APRS - position reporting both digitally through DMR and in analog at 1200 baud - and the radio offers flexible repeater functions: cross-band repeat that can even bridge an analog band to a digital one (or vice-versa), plus same-frequency repeat. A large 3000 mAh battery keeps it running, and it programs over USB.

The trade-off is complexity. DMR itself takes some learning - code plugs, talkgroups and color codes - and a radio this feature-dense has a deeper menu and software than a simple analog HT, so it rewards operators willing to climb the curve. For those who do, it is a versatile do-everything digital handheld.

It competes with other DMR handhelds such as the AnyTone AT-D878UVII and the long-running TYT MD-380.
