[Elecraft] K3 Low Pass Question

It begs the question what we should do with the 1000s of LP filters out 
there.  Some are built very well, like my Drake, but I also have a couple 
made of "bent tin."  There was a QST article on them a few years ago showing 
different construction styles and quite intriguing how costs could be 
reduced.

I was idly wondering if I should convert them to something useful, perhaps 
to a band pass filter.  There's room to fit small toroid inductors instead 
of the solenoid types.  Then again, with the Elecraft line up I probably 
wouldn't benefit much, but it would be an interesting project.
