That is not correct Walt, they form no part of the VOR/DME system. They are
as Brian says relatively crude. They are just LF/MF carrier with a morse
ident, simple as that. The aircraft uses a simple DF set to get a bearing on
the NDB, no different to a fox hunt on top band!!!

Most NDBs have in the UK have vanished or been replaced with VORs over the
years. Some small airfields do have low power NDBs where a VOR/DME is not
justified.
