I was surprised to learn that the silicon point contact diode was
patented in 1906.

And it was strictly a curiosity until much later. When did it enter into 
mass production?

 SSB was developed in the 20's as was TV.

This thread has me wondering how accurate IMD or even PEP was measured in 
the late 50's, early 60's. Would the readings that National provided for 
their 4CX1000A military amp hold up to todays techniques and 
instrumentation?
