Creating a Custom LoTW Mode Mapping File for Aether

The ARRL's Logbook of The World system only accepts certain operating modes as valid. The ARRL's LoTW FAQ page lists the currently supported modes. Sometimes, you may log QSOs with a mode not supported by LoTW. For example, "FM" is a supported LoTW mode, but "FM-W" (FM Wide) is not. Normally, QSOs logged with a mode of "FM-W" will not be accepted by the LoTW server. Aether can be set up to convert a particular logged mode into a mode that LoTW supports before uploading a QSO to LoTW. To enable this functionality, you must create a custom "LoTW mode mapping file". This page describes how to do that.

Note: By default, Aether will automatically convert USB and LSB to SSB before uploading to LoTW, as these are very common logged modes.


Note that Aether installs the mode mapping file in the folder /Users/yourusername/Application Support/Aether, and it can also be manually installed by placing it there and restarting Aether.
