[Elecraft] P3 desires

[Don Wilhelm]

Bill,

It would be nice, but it may not be possible.
Remember that the IF output is prior to the DSP, and the DSP is where 
the notch is generated.
So the signal input to the P3 does not contain any notch information.
You can say that "it is just a small matter of programming" since the K3 
and P3 'talk' to each other, but the necessary information probably is 
not available from the DSP, nor is there any provision in the P3 to 
process that information.
So that "small matter of programming" would become a very large hit to 
both the K3 and P3 firmware.

73,
Don W3FPR
