[Elecraft] Re: AGC Design of the K3

Hi,

I am very curious about the variable filters, a concept which has been  
proved in the K2. However I also wonder if the non-linearity of the  
diodes (and on top of that the crystals) will not cause more problems  
in the K3 environment than they solve. In many modern receiver  
concepts with very strong front ends, the crystals in the filters have  
become the limiting factor.

I wonder if the 8 steps, which Wayne mentioned, mean that diodes will  
not be used but switched Cs...

It will be very, very interesting to see what Elecraft comes up with.  
If the IMD behavior is equal to that of the current filters, this will  
be really cool.

Fingers crossed, vy 73 de toby
