<p>1. Add an audio amplifier to solve the problem of extremely low volume of SSB single sideband, and the effect is obvious.</p> <p>2. Redesign FM and HF bandpass filters,</p> <p>3. 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>4. Use FPC soft board, the board thickness is 0.12mm, safe and reliable without short circuit, and the installation does not support the speaker.</p> <p>5. Use high-quality high-frequency wire-wound chip inductors with high Q value, small internal resistance, and strong filtering selectivity.</p> <p>It is suitable for K5\/ 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>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 for-original machine.</p> <p>The FPC soft board uses a double-sided disk, which is easier to connect to the for original-machine.</p> <p>Applicable models:For uv k5\/k6</p> <p>Due to different product batches, the appearance may be different, which does not affect use.</p> <p>Type:A:Loose parts,Not assembled</p> <p>Colour:As Shown</p> <p>Material:PC+Metal</p> <p>Package Contents:</p> <p>1 * Modification Module</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. The measurement allowed error is +\/- 1-3cm.</p>
