Autonotch is of limited value with CW and these are CW radios.

The "give up" is probably absolute minimum power consumption. 

>From a practical point of view, giving up some degree of 
flexibility - perhaps a limited number of bandpass filters 
and a fixed (in set-up) center frequency - would probably 
be acceptable.  With DSP it might also be reasonable to give 
up some degree of performance (ultimate rejection) in the 
crystal filters as they would be similar in function to the 
roofing filter in the K3.
