• Upgrade content:1. Add an audio amplifier to resolve the issue of extremely low quantity of SSB unmarried sideband, and the impact is obvious. 2. Redesign FM and HF bandpass filters, 3. An ESD tube is added to the enter terminal for electrostatic protection and strong sign defense when transmitting within the UV section of twin antennas. 4. Use FPC smooth board, the board thickness is 0, secure and loyal with out brief circuit, and the set up does not help the speaker. 5. Use nice high-frequency wire-wound chip inductors with immoderate Q value, small within resistance, and powerful filtering selectivity. 6. In the dual-antenna solution, an extra level of band-pass filtering is added to the antenna enter end, and a feeder and SMA head are used to an HF self sustaining antenna from the LED, which would not impact the UV functionality of the machine. 7. The FPC smooth board makes use of a double-sided disk, which is simpler to hook up with the machine. Applicable models:For Quansheng uv k5/k6 Due to diverse batches, there may well also be variations in product appearance, color, and printed text, that will no longer influence the use. Colour:orange yellow Material:PCB Package Contents: 1 x SI4732 Board Only the above kit content, various merchandise are not included. Note: Light mirrored image and diversified displays may cause the colour of the object in the photo a bit different from the real thing. The measurement allowed error is +/- 1-3cm.
