Laurie, Thanks for a really helpful program. However, on 20 m for example I see many stations displaying "B4" that I indeed have worked before. If I move to 15 m and I know that I have worked B4 it does not show "B4". In fact on 15 m it is rare to see a "B4" displayed. I am not sure of other bands since I am concentrating on 15 m presently. Many thanks Neil N4FN
