What kind of diodes are you referring to?  How many volts are we talking
about?  Wouldn't this de-sense the receiver by quite a bit?  Before a
diode even gets into full conduction, it enters a non-linear region.
All sorts of mixing products will be present.  I'm guessing the
distortions you are referring to are the mixing products that occur.
Are you thinking of using small signal diodes? What would be the FV?

   Well this may be dumb, but I still dont understand why anyone would
operate three transmitters

in the same place on the same frequency.  What are HFPackers?
