[TenTec] Orion 2 situation

[Al Gulseth]

"The higher the voltage excursion, the longer the linear portion of the 
output/drive power curve. For this reason, amplifiers powered from 40V or 50V 
DC exhibit considerably better linearity, and thus lower IMD, than 13.8V 
units."

This sounds like a good "executive summary" of the issue to me. 
The "inganeers" on the list are welcome to comment as to its validity.
