The BTECH GMRS-50V2 is a 50-watt GMRS mobile radio that delivers high power in a compact package. It is a popular choice for operators who want maximum transmit power for vehicle or base station use without the complexity or price tag of some higher-end models.

Why it's popular

The GMRS-50V2 offers the full 50 watts allowed by GMRS in a form factor that is easy to install in most vehicles. It includes NOAA weather alert reception, repeater support, and a straightforward interface. For operators who want a no-nonsense mobile radio that focuses on power and reliability, it checks the important boxes at a competitive price.

Key specs

Form factor: compact mobile unit suitable for dash or under-seat mounting
Display: front-panel LCD with channel and frequency information
Antenna connector: SO-239 (standard UHF connector for external antennas)

Getting started

Plan your installation. Choose a mounting location with good ventilation. A 50W radio generates significant heat during transmit.
Wire power directly to your vehicle battery using the included power cable. Do not use a cigarette lighter adapter — the radio needs more current than those outlets typically provide.
Connect an external antenna. A magnetic-mount antenna works for testing, but a permanently mounted antenna will give better performance. Check SWR before transmitting at full power.
Program your channels via CHIRP or the front-panel controls.

Antenna matters: A 50W radio with a poor antenna will perform worse than a 20W radio with a good antenna. Invest in a quality external antenna and verify your SWR is below 2.0:1 on the GMRS frequencies before running full power.

Programming with CHIRP

The BTECH GMRS-50V2 is supported by CHIRP. Select "BTECH GMRS-50V2" as the model. You will need a BTECH/Baofeng-compatible programming cable. CHIRP lets you set up all your GMRS channels, repeater settings, power levels, and tone configurations from a simple spreadsheet interface.

For a complete walkthrough of the CHIRP software, see the Programming with CHIRP guide.
