The link below will allow you to download an updated prefill exchange file for the ARRL DX CW contest next weekend. The file contains 3,772 unique calls signs from logs submitted for the years 2010 through 2014. Please note however that the calls contained within this file are US/VE calls only and contains only their respective states/provinces. This means the file is ONLY for use by DX stations who will be contacting US/VE's in the contest and NOT for use by US/VE stations. All US/VE stations will need the DX stations power level, which is not contained in this prefill file. Consequently it will not work for stations on the US/VE side. https://www.dropbox.com/s/zn7vg8vgh1dwqeo/ARRL%20DX%20CW%20Call%20History.adi?dl=0 If you need assistance in how configure WriteLog to use a prefill exchange file this link provides a short tutorial. https://www.dropbox.com/s/mckz6zbuklff0up/WriteLog%20Prefill%20Exchange%20file%20loading%20instructions.pdf?dl=0 73, Gary AL9A
