BTECH Mini UV-25X4 25 Watt Tri-Band Base, Mobile Radio: VHF, 1.25M, UHF Amateur (Ham)

What Makes the UV-25X4 Unique: Dual Synchronize Display Mode, Mic Audio Gain Settings, In depth user's guide, Auto Power Off Function, Channel Mode Editing Settings, Auto Scan, Scanning Resume, and Variable Frequency Scanning, Quad Watch Delay Time, Randomization Privacy Mode, Builds upon previous generation UV-2501+220.
Frequency Range: 144-148MHz (VHF), 222-225MHz (1.25M), 420-450MHz (UHF).
Broad (Wide) / Narrowband (Narrow) Selectable.
Recommended Accessories: Pair UV-25X4 with the Nagoya TB-320A Antenna (and RB-50 Magnetic Mount) for easy installation. The PC04 FTDI Cable is recommended for easy computer programming.
Dual Watch monitoring VHF/UHF and 220Mhz: The 220 MHz band antenna lowpass filter is switched with a relay and the 2 meter lowpass filter and 70 cm highpass filters are switched with PIN diodes - resulting in a audible relay switch noise when monitoring 220MHz with VHF/UHF simultaneously. A relay that completely isolated the 220 MHz RF filter won't impact the RF performance of the 2 meter/70 cm bands. If monitoring multiple 220MHz or VHF/UHF simultaneously the relay is not heard or used..
