Region2 and Region3 users, please note! (No harm for Region1 users to do this also. Specially for UHF/SHF bands as there may be restrictions by countries)
Cqrlog uses band limits by Region1 setings as default.
Region2 and 3 users should check NewQSO/File/Preferences/Bands. There is a button "Frequencies" that opens frequency table.
Band start and end frequencies should be modified by own region settings. That has effect for many things. First you notice it when you try to import adif that has qsos with frequencies over or under band limits.
Also many other function use this bands/frequencies information.
If you modify them you should also check mode limits inside the band. It has effect to DXCluster spot marking (by colors you have choosen).
