Mirkit x Baofeng Radio UV-5R MK3X 5 Watt FCC Approved 2022 2100 mAh Li-ion Battery, Tri-Band Radio Mirkit Edition and Neck Strap Lanyard Mirkit Ham Radio Operator

...ng, 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..
Tribander Mobile Radio Kit Includes: BTECH UV-25X4, Speaker Mic, 6 foot DC Cable with Cigarette Plug Connector, Radio & Mic Brackets, Mounting Hardware, and User Guide.
