If you generate your own datafiles, extract only the files you want replaced.

cklist.dat - Pack Rat op name and bands used.
ck2list.dat - Calls w/operator names.
logsort.dat - Good Calls file.
ratslist.txt - Printable Pack Rat bands list.
sixdigit.dat - 6-digits (SQUARES file).
vhf4k.adi - 5000+ callsign ADIF (created by K9PW - updated by W3KM).
Note: You can use your own ADIF and select it in VHFLOG and KM Rover.
      This file must be in the same format as vhf4k.adi however.

VHFLOG or KM Rover users living in the NE part of the country are welcome
to use my datafiles. Extract the files you want to the c:\vhflog32 or
c:\kmrover32 folder. To see the changes, run the logger after updating.
