Features 1、Compatible Devices: Radio modification module specially designed for Quansheng UV K6 UV K5, with memory chip, add the SI4732 softboard FPC for the 2 way radio, modified HF short wave full band reception, single sideband reception, for single antennae, dual antennae. 2、Sound Performance Improvement: This radio modification module adds sound amplifier to effectively solve the problem of low volume of SSB single sideband reception and significantly improve the sound quality. 3、Enhanced Bandpass Filters: 2 way radio modification module, FM and HF bandpass filters have been redesigned to optimize signal filtering and reception quality in different frequency bands. 4、Electrostatic Guard: Integrated ESD tubes at the inputs ensure strong guard against electrostatic and strong signals when transmitting with dual antennaes in the UV section. 5、FPC Soft Board Utilization: Use 0.12mm thick FPC soft board to ensure safety and reliability, prevent short circuit, and support the installation without speaker, FPC soft board with double sided disk, more convenient to connect with the original machine. 6、Premium Inductors: Premium high Q value high frequency wire wound chip inductors are used to enhance filtering selectivity and reduce internal resistance, thus improving signal filtering performance. Specification Item Type: Radio Modification Module Material: PCB Chip: SI4732 Application: For Quansheng UV K6 UV K5 Radio Single Antennae and Dual Antennae Upgrade Content: 1. Add sound amplifier to solve the problem of extremely low volume in SSB modulation, with significant effect 2. Redesign FM and HF bandpass filters 3. Add ESD tube at the input end for static guard and strong signal guard when transmitting in the UV band with dual antennaes 4. Dual antennae solution, additional first level bandpass filter at the antennae input end, use feeder and SMA head to form an independent HF antennae with LED, without affecting the original UV performance of the machine 5.
