Feature:1. Compatible: Designed for UVK6 UVK5 radio, install S14732 soft board FPC for K5 K6 and modify HF short wave full band reception/single sideband reception. Suitable for single aerial and dual aerial.2. Amplifier and Bandpass Filter: Addition of amplifier effectively solves low volume issues in SSB single sideband reception, significantly enhancing sound quality. Redesigned FM and HF bandpass filters optimize signal filtering and reception quality across different frequency bands.3. ESD Protection: Integrated ESD tube at the input end, ensures robust protection against static discharge and strong signals when transmitting in the UV section of dual antennas.4. FPC Soft Board Utilization: Utilizes 0.12mm thick FPC soft board for safe and reliable installation, preventing short circuits and supports installation without speaker. Adopt double sided disk, easier to connect to the original machine.5. Premium Inductors: Adopt high Q value high frequency wirewound chip inductors to enhance the filter selectivity and reduce the internal impedance, thus improving the signal filtering performance.Specification:Item Type: Radio Modification Module Material: PCBChip: SI4732Compatible Devices: Quansheng UV-K6 / UV-K5 Radio Single and dual AerialUpgrade Contents:1.
