Hi,
I have a current dxcc entity list in text format, courtesy of 425dx.org, which is a great free weekly dx newsletter from Italy.
I've edited it to include the 4 new pj entities.
While the main prefixes in use for each country are listed, it's in no way an exhaustive list of the more obscure prefixes which appear from time to time.
If anyone would like a copy just drop me a post and I'll be happy to send you the file.
Cheers,
Tim, (GI4OPH)
