JT-Bridge looks for CQ calls in WSJT-X and checks in your logging application (Aether, MacLoggerDX, RUMlog or RUMlogNG) for QSO and QSL status of the call and DXCC Entity.

The call can be looked up in QRZ or HamQTH call books, to include QSO/QSL check of CQ zone, ITU zone, State, IOTA and Grid.

It’s possible to filter the list to show QSL status for the current band and/or mode.

With call book lookup, JT-Bridge will also show if the CQ caller is using LoTW or eQSL.

Alerts can be sent to OS X Notification Center. Logged QSOs in WSJT-X can be sent to your logging application.

A simple CAT interface enables some control of the transceiver via your logging application.

Information about the call that is being worked in WSJT-X can be shown.

Macros can be defined to set the free text message in WSJT-X with information about the CQ caller.
