1. Use a dedicated network karaoke USB sound card chip to make the sound clearer and the noise floor lower. Another advantage is that YY can be specified to use a USB sound card connection, and the sound card that comes with the computer can be used for watching movies or playing music without affecting each other.
2. Use a dedicated USB chip to detect the SQL signal of the radio station, and use the SQL signal to control the YY software forwarding. Replaces the original VOX trigger. Avoid the voltage induced by the connection line to trigger the YY forwarding by mistake. The anti-interference ability has reached a super level.
3. Use a professional sound detection chip to detect the sound of the computer speaker and control the PTT, so that the mobile station or relay can forward the sound of the computer speaker.
4. The computer terminal controls the PTT of the mobile station, and uses an optocoupler for photoelectric isolation to ensure that the noise from the computer terminal will not crosstalk to the mobile station.
5. Use a customized high-quality isolation transformer to isolate the audio of the USB sound card and the audio of the mobile station to further reduce interference!
6. Use magnetic beads to isolate power supply interference and high-frequency radiation.
7. The PCB adopts high-quality materials: FR4 double-sided, fire rating: 94V0, all components on the board are high-quality SMD components.
8. Use an all-metal casing to isolate all space interference.
9. Add support for ASL
