There's also this entry:
13 -42.72933900 170.95621900 146 11750 100 0.0 HK HOKITIKA
NDB-DME
which is the DME part of the NDB-DME.
As Torsten notes, none of the receivers in FG at present do pairing of
NDB-DME frequencies, and I have no idea if any real world equipment
can do this - or if there's even a defined pairing scheme. You can
happily tune your ADF to 310KHz, and a DME receiver to 117.5MHz, and
either/both should work, but there's no link between the two other
than their geographical co-location.
Again, if anyone with more knowledge of such facilities wants to
comment, please do.
