[Boatanchors] Electronic TR Switch?

[J. Forster]

A properly functioning mechanical switch cannot, but if the RF power into an electronic switch exceeds the allowable threshold, the switching elements be it a tube or transistors or diodes, will turn on or off during part of the cycle. This non-linearity makes harmonics and other trash, hence TVI.

Unfortunately,  I traded it off years ago-so I can't try and duplicate a similiar incident.  I've al;ways been taught that unwanted harmonics are generated by a mis-tuned transmitter or transceiver or a exciter that is poorly designed and dosen't have parasitic suppressors.  Let's hear from the rest of the grouind with your take` on this comment.
