For K5 K6 SI4732 Board FPC Modification HF Shortwave Full Band Reception+2M Expansion Chip+Programmi
1. Add an audio amplifier to solve the problem of extremely low volume of SSB single sideband, and the effect is obvious.
2. Redesign FM and HF bandpass filters
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.
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.
5. Use high-quality high-frequency wire-wound chip inductors with high Q value, small internal resistance, and strong filtering selectivity.
6. In the dual-antenna solution, an additional level of band-pass filtering is added to the antenna input end, and a feeder and SMA are used to an HF antenna from the LED, which does not affect the UV performance of the machine.
7. The FPC soft board uses a double-sided disk, which is easier to connect to the machine.
