Are you saying the newer  t90's don't have the intermod problem?  Mine is
terrible, but I've had it a couple years.  I find the same thing on shelf
life and I don't understand it.  I grab the t90 off of the shelf and it is
dead as can be, grab the f6 and it is running fine.
Like I said, both have their good and bad points.
