This page takes your adif-file for input. It then extracts all the contacts on the band you specify. If you have specified a maidenhead locator in the contact, the program will then use that to calculate the geographical position of the contact and then draw a line between that point and your homeqth. The program will make a kml-file for use in Google Earth to display your contacts. You can also specify a date-range if you wish.

Hamradio Deluxe has this function implemented, but I do not use this program, and I don't want to have a demo-version installed just for this purpose. This is more or less the same function, but tweaked a little bit to my liking.
