(CONFIG:) Tx:  Mode
The Tx Mode is a key parameter for setting all modem parameters. Configuration
and operatin is generally easier when you set Tx Mode first.
The Mode determines which modulation, code rates, FEC type and symbol rate
range are available and also if Pilots or Gold Code settings are available.
Changing the Mode will change one or more of these.
