[Dx4win] dxcc lists

[David J. McAulay]

Hi All

Could someone explain please how i go about this

I have say 120 countries worked and confirmed  on 28, 21 and 14 mhz
and i want to print out just 28mhz so this will ten allow me to go to my 28 
mhz box and
pull out all of the 120 cards to match what dx4win has just told me i have

How do i do this please.?
( i've looked but carnt find out how do it )

Thank you
