One question I have been meaning to ask........

Can someone please clarify "Loading" ??

When I turn my LOAD counterclockwise (CMDR HF2500),  the grid current drops
quickly with little drop in output pwr (as recommended). Am I increasing or
decreasing the loading of the antenna ???

I think I am increasing the loading (even thought the dial is going to a
lesser #), However, I think I read somewhere (maybe an Ameritron AL800H
manual) that seemed to contradict this (or their var. cap works in the
opposite direction - increased loading shows higher dial #) . 

I interpereted an earlier post as saying not to drop the grid by adjusting the
load, rather decrease the drive from the exciter. 

Sometimes I wish I was born 20 years earlier so I could have been taught tubes
rather than solid state when I was in school .

Thanks for the free education.
