// Helper decorator class that encapsulates the emulation of split TX
// operation.
//
// Responsibilities
//
// Delegates all but setting of other (split) frequency to the
// wrapped Transceiver instance. Also routes failure signals from the
// wrapped Transceiver instance to this instances failure signal.
//
// Intercepts status updates from the wrapped Transceiver instance
// and re-signals it with the emulated status.
//
// Generates a status update signal if the other (split) frequency is
// changed, this is necessary since the wrapped transceiver instance
// never receives other frequency changes.
