I was going through some boxes of stuff and unearthed
a device known as the "Rothman Modulation System." 

Apparently it is a screen modulation system employing
a small loop to obtain RF feedback so as to correct
nonlinearities in screen modulation thus enhancing the
quality of the audio as opposed to pure screen grid
modulation. Well at least it looks on paper.


Claims it it will work with rigs up to 1000
watts(input). 

Anybody heard of these being used?
