If you are after Five-Letter-Pronouncable-Names (also called 5LPN I believe), like MALBY, KATHY, SITET, etc, the most official list(s) I know of are at:
EUROCONTROL - The European AIS Database: Introduction to EAD Basic - Home Go to EAD Basic, register for PAMS Lite, login, Enter Applications, click on PAMS Lite, and you get a form to generate apparently Europe-wide lists of documents.
If you select
Authority = Country, Authority Type = Civil, AIP Type=AIP, Part = ENR
A list of documents should appear and you should find something like:
"Name Code Designators for Significant Points."
For example the UK has EG_ENR 4.4, France has LF_ENR 4.3, etc.
Documents with Navaid details are there too.
PS The abbreviation isn't 5LPN, it is 5LNC (Five Letter Name Code).
