C4FM Multiprotocol Server

Unfortunately, the DR1-X repeater does not offer a LAN interface to be able to be connected directly to a network. Furthermore, its internal repeater control does not support DG-ID (System Fusion II).

However, the DR1-X with its [Control I/O] connector offers the option of using an external repeater control, for example an MMDVM modem.
This expansion can be carried out without interfering with the repeater hardware and turns the dr1-x into a full-fledged mmdvm repeater, which now also supports DG-ID (System Fusion II) and can be connected directly to a YCS server.

very good experiences have been made with the following hardware:

• Raspberry Pi 4B
• Repeater-Builder STM32_DVM_USB (MMDVM-Board)
  • http://www.repeater-builder.com/products/stm32-dvm.html
• pistar-ea by Manuel EA7EE (DG-ID FULLY SUPPORTED)
  • http://pistar.c4fm.es/

• 15pin D-Sub connector (male) (for connection to DR1-X [CONTROL I/O] connector)
• 9pin D-Sub connector (male) (for connection to STM_DVM_USB MMDVM-Board)
