A tiny tri-band mobile that fits where larger rigs will not and watches several channels at once. Antenna and AC power supply are extra, and monitoring the extra band alongside others makes an audible relay click.

Overview
Not a full-size mobile rig that needs a big dash cutout, the BTECH mini mobile covers three ham bands in a compact body with brackets for the radio and mic. It runs on vehicle DC power or a separate supply at a desk.
Three bands and multi-channel watch in a body this small suits tight vehicle installs. The antenna and base power supply are sold separately, and the relay click when mixing the extra band with the others may bother some operators.
Who it's for
Mobile operators who want the extra band without a second radio get a small, versatile rig. Those wanting a plug-and-play home station should budget for the power supply and antenna.
Pros and cons
- Three bands in a compact body
- Watches several channels at once
- Bundled adapter opens many audio accessories
- Mounting hardware for radio and mic
- Antenna not included
- Power supply for base use sold separately
- Relay click when mixing bands
- Output power missing from the specs
Performance notes
Band switching on the extra band uses a relay, which is why a click is heard when monitoring that band alongside VHF or UHF. Range depends on the external antenna you add, and the suggested tri-band antenna simplifies matching all three bands.

Yes, with the optional RPS-30M power supply, sold separately.
Why do I hear a click on the UV-25X4?
The 220 MHz filter is switched with a relay, so monitoring 220MHz with VHF or UHF at the same time makes an audible relay noise.
