P25 DMR YSF Mini Hotspot Board Duplex with Screen and Shell for Pi-star Raspberry Pi MMDVM Mobile Power Supply
Description:
- This board is only applicable to Mini Duplex MMDVM board.
- Setting up Pi star software and Raspberry hardware (rpi 0-3) requires removing the Right Socket for the new pi4b.
Pi Star Regular Configuration of MMDVM-DUPLEX:
- Set controller mode: duplex repeater or simple
- RF: Freq: 144-148, 219-225, (main frequency band) 420-475, 842-950
- Duplex mode: Example: RX: 438.000000 TX: 433.000000
- Duplex mode: Example: RX: 145.000000 TX: 433.000000
- Simple mode: Example: RX: 438.000000 TX: 438.000000
- Wireless/modem type: STM32-DVM/MMDVM_HS-Raspberry pi Hat (GPIO) or any other (GPIO board)
- Option: (Not needed now, some old boards need to set) Admin -> Expert -> Edit MMDVMHOST -> RXOFFSET=0 TXOFFSET=0 (default value in pi star) (Update: New 3225 TCXO on February 2019, so offset is 0)
- Update new firmware: (pi star/Expert/ssh access/user: pi star pass: Raspberry)
- sudo pistar-mmdvmhshatflash hs_dual_hat
- The default error rate is less than 5%, and the default offset is 0. If the error rate is greater than 5%, as long as the signal can be received, it can be corrected through offset.
