I am experimenting with a digital repeater now. I will share my progress below.

My setup right now is:

Motorola CDM Receiver, Morotola CDM Transmitter

Flat Pack mobile duplexer, 25 Amp power supply.

Repeater-Builder STM32_DVM_PiHat Interface to a Raspberry Pi 3B

Status can be found on Brandmeister

Frequency 438.4125 -5 MHz, CC2, TS1 Steerable, TS2 Local Only

TS1 TG 314990

Coverage is limited right now, I am still testing it out and have it on a compromised antenna.

I do plan on also enabling in the future the ability to use P25, and NXDN.

I am using Pi-Star as the core software that provides a web-based dashboard for managing digital voice configurations.
