Thanks for updated CQDXMarathon program, Joe. The readme file says: (3) YOU MUST have the UPDATED PJ's and Z8 and E6 in your Refdata and Logbook mdb files. Information on these are avalable in http://www.ng3k.com/Dxcc/dxcc.html Could you please repeat the procedure to update these prefixes? 73 de LA9RY Knut Meland
