מאָונטינג די ראַדיאָ

The UV-25X4 includes all necessary mounting hardware for installation in a vehicle. For home or office use, the radio can be converted into a base station with an optional RPS-30M power supply (sold separately).

מאַכט קאַנעקשאַן

Connect the supplied DC power cable to the radio and to a 13.8 Volt DC power source. Ensure proper polarity. For mobile installations, connect directly to the vehicle's battery. For base station use, connect to a compatible DC power supply.

אַנטענע קאַנעקשאַן

Connect a suitable tri-band antenna (e.g., Nagoya TB-320A) to the antenna connector on the rear of the radio. Ensure the connection is secure and the antenna is properly tuned for the operating frequencies (144 MHz, 220 MHz, 430 MHz bands).

אַודיאָ אַרייַנשרייַב / רעזולטאַט

The UV-25X4 features an RJ45 microphone port and includes a K1 audio adapter for enhanced audio input/output. This allows for connection to a wide range of aftermarket audio accessories.

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.

אַרויסווייַז קאַסטאַמייזיישאַן

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.
