I'm just getting into ham radio. I'm trying to connect to a repeater here in Ireland:

  • Channel: RU260(RB10)
  • Output: 433.250
  • Input: 434.850
  • Call sign:EI7SHR
  • Access: Carrier

What does the "Carrier" mean here?

I was expecting a PL/CTCSS frequency.

    $\begingroup$ "ham", when used to refer to amateur radio, (i.e. ham radio) is not an acronym. No need to capitalize it. $\endgroup$

"Carrier access" just means that you do not need a CTCSS tone to access the repeater. Your carrier brings up the repeater.

CTCSS access may reduce co-channel interference between repeaters if their coverage area overlaps, but it is not technically necessary for access.

  • $\begingroup$ Some repeaters use a burst tone (a short audible tone at the start of the transmission) or DTMF for access as well. $\endgroup$
