   That would be an expensive top of the range SDR.   
   Most only digitize a small section of the HF bands at a time.   
      
   The Airspy HF+ Discovery I use with my PC for LF, MF and HF can only   
   digitize up to about a 700kHz wide section.   
      
   Does it work better than my analog receivers? - Yes I think so but my   
   analog receivers are all quite simple and cheap.   
      
   I don't think the digital processing gives any inherent advantage   
   compared to analog. But advanced features like noise reduction and   
   impulse noise blanking are more likely to be available with SDR since   
   they are then just a bit of extra software rather than some extra   
   hardware. Neither seems to give me a huge advantage though.   
      
   Actually good noise reduction is probably digital anyway, even when the   
   rest of the receiver is analog.
