Strengths

A 25 W GMRS mobile with a dual-band scanner at a budget price. The VHF/UHF scanning receiver (136-174 + 400-480 MHz) adds NOAA weather, MURS, marine, and other frequencies as receive-only channels, similar to the BTECH approach. Quad standby monitors 4 channels, with 260 privacy codes and VOX 1-9. It is CHIRP programmable with the included cable, uses a standard SO-239 antenna connector, and installs via a cigarette-lighter plug. A speaker mic and holder are included, and it is compact at 450 g.

Weaknesses

25 W is mid-range (the BTECH 50X1 and Midland MXT575 offer 50 W). The included programming cable has Windows 11 compatibility issues (Prolific chip; an FTDI cable is recommended). Actual output averages ~18 W. No NOAA weather is pre-programmed (you add it via the scanning receiver). Build quality is adequate but not Midland grade. The dealer network is limited, with email-only support.

Verdict

A mid-power GMRS mobile with a scanner. The DB25-G competes with the BTECH GMRS-50X1 at a lower power level (25 W vs 50 W) but a similar price. The dual-band scanner, quad standby, 260 privacy codes, and CHIRP support make it a capable platform. For operators who want a scanning GMRS mobile without 50 W, it is a reasonable choice.

The Radioddity DB25-G is one of the radios that made GMRS take off with overlanders: a compact, computer-programmable 25-watt GMRS mobile at a fraction of the price of name-brand gear. It is a Part 95E GMRS radio, so legal use needs an inexpensive, no-test family license, and unlike a handheld its 25 watts into a roof antenna gives real range for a convoy or a base station.

It covers the 30 GMRS channels (the 22 main channels plus the 8 repeater inputs) with three power levels, 25, 10, and 5 watts, a wide scanning receiver across VHF and UHF (which can hold NOAA weather channels), and a "quad watch" that monitors four channels at once, an unusually handy feature for keeping tabs on several groups. Note that on the FRS-only channels 8 to 14 it receives but does not transmit, because those channels are limited to low-power handhelds. Programming is done with Radioddity's software or CHIRP (a cable is included, though its Prolific chip can fight Windows 11).

It connects to an external antenna through a standard SO-239 jack and runs on 13.8 volts (a cigarette-lighter lead is included, though full 25 watts wants a proper supply). Do not confuse it with the newer DB20-G, which is a different 20-watt model. As a handheld companion on the same license, Radioddity's own GM-30 pairs naturally, and the BTECH GMRS-50X1 is a higher-power mobile alternative.
