Just wondering if it's possible (or as a feature request) to be able to filter call signs by location (and/or by specifying a single call sign to be blocked) ?
When trying to work DX (esp for a particular country or region) it would be nice to filter out all the unwanted call signs as well as same location hams who respond to DX/EU/AF, etc calls. I envision call sign naming convention logic can be applied to this and possibly some lookups to QRZ (if user has a subscription account).
Just a thought. Thanks much for the hard work on the program!
