Triple-Band Functionality
The UV-25X4 operates across three amateur radio bands: 144 MHz (VHF), 220 MHz (1.25M), and 430 MHz (UHF). You can select any of these as the primary transmit/receive band.
Dual Watch and Quad Watch Monitoring
The radio supports simultaneous monitoring of multiple frequencies or channels. You can monitor up to 3 other frequencies or channels while operating on a primary band. The Quad Watch feature allows for simultaneous monitoring of four channels.

When monitoring 220 MHz simultaneously with VHF/UHF, an audible relay switch noise may occur due to the antenna lowpass filter switching. This is normal operation and does not affect RF performance on 2 meter/70 cm bands.
Ekran Özelleştirme
The radio allows for customization of its display, including the ability to synchronize and display up to two channels with both their channel name and frequency.
