Lookup is an windows phone app that allows you to perform amateur radio callsign lookups via QRZ
.COM. It also incorporates DX cluster feeds, DXCC information retrieval and Solar data all within one application on your Windows Phone. For callsign lookups, the application uses the QRZ
.COM XML interface, please register at QRZ
.COM for an account if you do not already have one. The application will happily work with a free QRZ
.COM account although it is recommended to use a paid account, as a minimum the XML Logbook Data paid option, in order to access the full functionality of callsign lookups within the application.
