[Elecraft] P3 adding rf protection diodes question

Eric:
I would suggest an Elecraft adapter kit for the P3. The kit would contain the elements you suggest except an external battery pack and handy carrying handle. I would add ESD protection to the P3A? 
I think the P3A and kit would compete favorably with other commercial RFI tools costing 10x$. I can see a book in the future, 'Chasing RFI with the P3' as well.
Wouldn't be cool to see P3 SNs higher than the K3 SNs?

>In the lab here at Elecraft we took apart a M-F BNC 50 ohm terminator and put the back to back diodes inside. When we need to search the building for RF interference we just add it to the rear of a P3 running on batteries and use it with a collapsable whip and right angle BNC.
