Source List ID

Particular Source List ID is a integer number from 1 to whatever last source entry is used by EdgeTX developers during firmware implementation. Different Radios have different number of physical inputs that affects this list. Therefore for the same source type (ie LS04 - Logical switch number 4) sourceListID can have different value on particular radio model

To avoid confusion wherever there is reference to Source List ID short-name sourceListID is used.

Source List Name

To avoid confusion wherever there is reference to Source List Name short-name sourceListName is used.

Source List name can also change due to firmware changes during development or user configuration (ie. assigning custom name to input). In current version of EdgeTX firmware Source List Name also may contain special visual symbols to indicate type source (see ).
