//Class IBdaTuner is a pure virtual base class for BDA tuner/demod objects that supplies

// for the signal strength. 
//
// The member functions should have the bdaTuner_ prefix so that they can be differentiated
// from other functions in multiple inheritance. 
//
// Be sure to leave this class with only functions in it to prevent extra overhead if it
// is used for multiple inheritance.
