What is the digital color code used on DMR repeater systems?

  • A.An access code which must be programmed into a DMR transmitter to access a specific repeater (correct answer)
  • B.A code which automatically programs the repeater offset to a frequency chosen by the user
  • C.A code which identifies the specific CODEC being used so that the repeater can properly decode the audio
  • D.A code transmitted by the repeater to indicate health and status of the equipment

WhyA DMR digital color code is an access code that must be programmed into a DMR transmitter to access a specific repeater. DMR repeaters distinguish between multiple, otherwise-identical-sounding digital streams sharing a channel using a color code, an access parameter that must be programmed into your radio to match the specific repeater you're trying to use, functioning much like CTCSS does for analog FM, answer A. It doesn't set your offset automatically (B), it isn't a codec identifier (C), and it isn't a status broadcast from the repeater (D), it's strictly an access-matching value your radio must be configured with.
