You know Peter, that is a good example of voodoo
pathological science.
I spent quite a bit of time investigating PIN diodes vs.
regular diodes in my rigs and found absolutely no difference
at all. Yet people who do the mods will swear they work.
Look at Sherwood Engineering's site at a PIN modified ICOM
781. Click here and find the "Sherwood's tests" link at the
page top:

The modified 781 is 6dB worse for close spaced IM3.
The best any of my tests did on a couple FT1000's was break
even, yet people swear it makes a huge difference.
Amplifiers are no different.
