[Elecraft] IMD and supply voltage

[Rich]

Guys,

This comment in no way is mean spirited, but truly a concern after 
reading all of this tech data.

For those of us who do not have 100K in test equipment and a EE,  I am 
starting to feel like I should not even get on the air.   I get the 
concept, but the best I can do is make good clean connections, do not 
overdrive my audio and hope for the best.  I have to have faith in the 
equipment builders or find a new hobby.
