Cross-linking with BrandMeister

To create cross-link you need several things:

  • An valid FRN node account.
  • Some FRN software for Linux to make integration with FRN network. We recommend to use AlterRFN client software.
  • Special utility named CallCapture to translate callsigns that come from FRN into DMR IDs.
  • One of supported AMBE Dongles.

CallCapture and configuration files are available here - https://code.brandmeister.network/r3abm/AutoPatch.git
