SI4732 Chip and Crystal Oscillator Component Modification Module for Uvk5/K6 PLUS FPC Version for Quansheng UV-K5 UV-K6JAS 1.Add an RF amplifier to improve AM reception performance._x000D_ 2. Add an audio amplifier to solve the problem of extremely low volume of SSB single sideband, and the effect is obvious._x000D_ 3. Redesign FM and HF bandpass filters,_x000D_ 4. An ESD tube is added to the input terminal for electrostatic protection and strong signal protection when transmitting in the UV section of dual antennas._x000D_ 5. Use FPC soft board, the board thickness is 0.2mm, safe and reliable without short circuit, and the installation does not support the speaker._x000D_ _x000D_ In the dual-antenna solution, an additional level of band-pass filtering is added to the antenna input end, and a feeder and SMA head are used to an HF independent antenna from the LED, which does not affect the UV performance of the machine._x000D_ The FPC soft board uses a double-sided disk, which is easier to connect to the machine._x000D_ Applicable models:For Quansheng UV-K5/UV-K6_x000D_ It is suitable for Quansheng UV-K5/UV-K6 to install S14732 soft board FPC and modify HF shortwave full-band reception/single sideband reception. It is suitable for single antenna and dual antenna._x000D_ Different batches may have different appearances, but will not affect the use_x000D_ Colour:orange_x000D_ Material:PCB+electronic components_x000D_ _x000D_ Package Contents:_x000D_ 1set x walkie-talkie modification board_x000D_ _x000D_ Only the above package content, other products are not included._x000D_ Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
