APRS-IS Basic Settings

Where do I put my passcode?

There is no passcode necessary. If you have installed a license for QTH.app, the system will automatically generate a passcode. If you are running in unlicensed mode, QTH.app will use a passcode of -1, which is enough to connect and receive packets, but any outgoing packets will not be routed on the APRS-IS network.
