Mmdvm repeater.
The repeater's screen *should* look as in the picture; everything must be set to "yellow". For 'normal' operation, the DR-1X's screen should show as above. If not, the repeater will not be "engaged". 10. Calibrate MMDVM Now it's about the sausage and we get to the point where it gets a bit more complicated for most people.

No, you need a duplex hotspot for that. Most MMDVM's fake it. A real repeater can do it, but not an MMDVM. Just for clarity, I'm not talking about the hotspots (although it would be neat to use ...Family of MMDVM ver.2022 MMDVM Repeater V3F4 Functions : Build your DMR/YSF Digital repeater, hotspot use Analog radios, such as GM338,GM34...After setting up the MMDVM duplex hotspot board, it is necessary to adjust the transmit and receive offsets in the MMDVMHost expert editor section. Basically this corrects the transmit (TX) and receive (RX) frequency of the board, if they’re not on frequency. This is the BER 0.4% when no setting RX/TX offset.The MMDVM-Pi board is designed for repeater and high power hotspot applications - connects to user ... You cannot build firmware for the MMDVM-Pi v1.0 under Pi-Star v3.4.17 or below because the compiler doesn't fully support the STM32F7 chips. You must use the latest Pi-Star
The duplex boards have one immediate advantage over the simplex hotspots, which is that you can transmit even when your radio is in the middle of receiving. This means that you can easily unlink from a busy talkgroup even when the hams using the TG don't leave gaps between their transmissions. Another advantage of the duplex boards is that you ...
