 Marco Buttu (mbuttu@oa-cagliari.inaf.it): 
     I made just some adaptings to use the same code with the SRTKBandMF 
     receiver. This code is inherited by SRTKBandMFCore, so I made the 
     setMode function pure virtual and I removed the updateLNA() method, 
     which now must be implemented in derived class.
     I also changed the access label of some methods and attributes from
     private to protected in order to use them in the derived class.
