[Elecraft] P3 adding rf protection diodes question

[Sam Morgan]

Joe,
apples and oranges perhaps?
I think you answered the question as if I was asking about the K3's 
input...where as I was asking about the *P3* input which had no gas 
discharge protection.

Perhaps I should have mentioned I was speaking of using a standalone P3 
for the purpose of chasing rfi, as mentioned in a previous thread:
