// 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.
