This program uses a free XML feed from the HamQTH.com website of Petr, 
OK2CQR. His callsign database has over 1.3 million callsigns and is very 
fast, returning the station information in just a few seconds. Thanks to 
Petr for a great service.

Given a ham radio callsign, twHamQTH will display the name, address, 
city and country of the station. All of the station data can be use 
by other programs. 

You'll need a free HamQTH.com login to use this software.
