Tim,
As I remember it, there was a fair amount of ripple in the passband
on the VI and VI+, and the Inrad mod is a couple (more?) of capacitors that
were designed to help flatten that out a bit more. I bought the mod for my
Omni VI+, but ended up selling it to buy an Orion before I installed it, so
never got to see what the difference was.

Inrad doesn't give any detail on the mod. Can anyone shed some light on
just what is being done ?
