This UserSetting defines the radio output power of the module. The UserSettings parameter
RADIO_DefaultRfTXPower is entered as a complement on two. This value represents the
power at the radio ic without taking the antenna into account.
The user is responsible for adhering to the statutory regulations for the maxi-
mum power output when using this module. In case of the Themisto-I with an
external antenna the antenna gain needs to be taken into account, too.
