TxModeInfo declares a human-readable name and occupied bandwidth for the signal a transmitter is sending. It is intended for clients that generate their own modulation, typically with an IQ source, such as a digital mode that the server has no name for. Sending it is optional.

- Send it after TxAccept. It may be sent again to change the declaration.
- There is no reply.
- The current server records the declaration but does not yet display it anywhere. In particular, StationList still reports the transmitter's modulation field and its measured occupied bandwidth.
- Invalid values close the connection.
- Ignored on role 3 (
TX_GENERATED) connections.
