DXKeeper Filters

This filter works for 6M grids in any of the grid fields:

 // Display all 6 meter QSOs with a grid square // GRIDSQUARE LIKE '<filtertextbox>*' and BAND='6M' or APP_DXKeeper_Grid2 LIKE '<filtertextbox>*' and BAND='6M' or APP_DXKeeper_Grid3 LIKE '<filtertextbox>*' and BAND='6M' or APP_DXKeeper_Grid4 LIKE '<filtertextbox>*' and BAND='6M'

This filter is not band specific:

GRIDSQUARE LIKE '<filtertextbox>*' or APP_DXKeeper_Grid2 LIKE '<filtertextbox>*' or APP_DXKeeper_Grid3 LIKE '<filtertextbox>*' or APP_DXKeeper_Grid4 LIKE '<filtertextbox>*'
