I wonder if you could enlighten the group on this Alex.
First, could you tell us how shielding the tank circuit improves
IMD...since they are totally unrelated.
Second, could you tell us what FCC rule defines IMD limits, since
there aren't any listed nor do the ask for any such measurement to be
submitted in TA applications under part 97.
It sound to me like you are confusing harmonics with IMD.
