This release alters Pathfinder's "free callbook lookup via QRZ.com" service to compensate for Saturday's changes in the format of "QSL Via" information returned by QRZ.com (tnx to Aart PA3C) Users with a QRZ.com Data Access subscription can ignore Pathfinder 4.6.6. Pathfinder 4.6.6 is available via the DXLab Launcher and via 73, Dave, AA6YQ
