I am doing the FAA IR from the UK, and thought that perhaps they have
a system in the USA where (the case of the DME and the VOR being
co-located) the DME ident is combined into the VOR ident. Certainly
the King training video gives that impression, but it doesn't make any
sense to me.


While I've never used the King Video, I understant they are popular.

Every plane I've flown that had a DME had a separate switch on the audio
panel for the DME. When I went to Ident, however, I usually selected
both the VOR I was using AND the DME as a matter of expediency. So..
sorry that you ended up with faulty info.. but they are actually
separate in all regards except frequency pairing and location.... and
the location rule isn't hard and fast...

I recall there are a few approaches that use an ILS... but you tune the
DME from the on-field VORTAC for DME information during the approach.
Two separate installations altogether.. and in this case, the idents
would be different as well.
