[1000mp] Modifying The INRAD roofing filter board.

[VE2FWW]

Hello
I wonder if anybody in this group had modified the INRAD MARK V OR FIELD roofing filter board.
I read the informations on W8JI website.
This mod is done to keep proper input impedance  for loading the filter
There are two resistors to be changed on the INRAD board....R5...which is a 12 Ohms ...replaced by a 15 Ohms....and R6 which is 220 Ohms...replaced by a 150 Ohms...
I would like to know if anybody performed this mod on the INRAD Board....
I have Inrad Roofing filters in my Fields ...and it would be interesting to know the difference between the MOD and the NO MOD????
Any input would greatly appreciated...
Thanks
