I have downloaded the whole logbook for safe keeping but now I only wish to download a certain month. This I will add so that the saved log is updated. Is there any way I can do this?
This feature is not within the QRZ Logbook's current internal capability. I work around it using ADIF-Master shareware downloaded from http://www.dxshell.com/adif-master.html . This software will allow filtering of your QRZ downloaded ADIF file and the ability to save the filtered result.
