Petr, OK2CQR, created this useful Amateur Radio tool. As he notes, “This callbook provides all data for free and you will not have to log in to see any detail unlike other sites. It includes also XML access for logging programs. You can use everything from HamQTH as often as you want without limits. The server has lots of power available and the Internet connection is unlimited. By registering on this website server, you can also edit or correct your information and write a little about yourself and/or add photos.” HamQTH also has a customizable DX Cluster System. Very cool and highly recommended by yours truly, W9WSW.
