This mod seems to be wrong.
When dealing with mods I usually read different descriptions because they are 
not always correct.
This helped a lot me when I opened the TX of my 7800.

D60 exists only in USA models for keeping output power to 50W
- according to the mod I have atteached and another one I have found on mods.dk.
So this is highly probably the right mod.
It's D59 which has to be removed.
