<p>1.Add an RF amplifier to improve AM reception performance.</p> <p>2. Add an audio amplifier to solve the problem of extremely low volume of SSB single sideband, and the effect is obvious.</p> <p>3. Redesign FM and HF bandpass filters,</p> <p>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.</p> <p>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.</p> <p>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 antenna from the LED, which does not affect the UV performance of the machine.</p> <p>The FPC soft board uses a double-sided disk, which is easier to connect to the machine.</p> <p>Applicable models:For UV-K5\/UV-K6</p> <p>It is suitable for 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.</p> <p>Different batches may have different appearances, but not affect the use</p> <p>Colour:orange</p> <p>Material:PCB+electronic components</p> <p>Package Contents:</p> <p>1set x walkie-talkie modification board</p> <p>Only the above package content, other products are not included.</p> <p>Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
