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

  1. An access code which must be programmed into a DMR transmitter to access a specific repeaterRespuesta correcta
  2. A code which automatically programs the repeater offset to a frequency chosen by the user
  3. A code which identifies the specific CODEC being used so that the repeater can properly decode the audio
  4. A code transmitted by the repeater to indicate health and status of the equipment

Explicación

The color code is an access parameter on DMR: your radio's code must match the repeater's or the repeater ignores you, much as a CTCSS tone works on analog FM. It has nothing to do with offsets, codecs or equipment status.
