[Elecraft] Using Yaesu Quadra VL-1000 with K3/ ALC?

[john at kk9a.com]

Every amp that I use I would overdrive with the Elecraft set at 100  
watts. I am not familiar with the Quadra, I typically adjust the PWR  
(power output) control to the desired wattage and have not had an  
issue with any that that I have used. I see a lot of talk about using  
ALC on the SPE Expert amp list. I have not used this brand and do not  
why ALC appears to be recommend for them.  I have not connected an ALC  
cable in decades.

Yes.  The Quadra produces is rated 1000 W output with approximately
60W drive.  The K3 will overdrive it resulting in splatter/IMD and
potential damage to the transistors.
