Mmdvm repeater.
The Repeater-Builder STM32-DVM is, we think, the best MMDVM Modem board out there. It includes a powerful micro controller, lots of test points, a well-tested filter design, nice diagnostic LEDs, and a handy 'clip' light for easy RX level adjustment. We'd long talked about trying to stuff the Pi+PiHat STM32-DVM into the MTR2000's card ...
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.
