I was surprised that XF4IH did not show up as a new country in my packet window. When I checked, DX4WIN had assumed that it was Mexico. I logged it and changed the prefix to XF4. I then deleted the QSO and, of course, it then showed up as a new country within the packet window. Now, I just to need to work it for real! But at least the alerts will recall me to the radio whenever it's spotted.
Just thought I'd mention this, in case anybody else has a similar experience. Ian G4IIY
