[Amps] Alpha vs Henry

[Al Kozakiewicz]

1500 watts continuous for 30 minutes; 2500 for 30 seconds. 

Even if I do nothing but call CQ every 2 seconds, that's probably "only" about a 60% duty cycle.  I'm just trying to get a feel for how much derating is prudent when using the thing for extended periods of time.
