[Amps] Al80b

Bingo.  I'd say the same thing.

12:1 SWR is 42% reflected power and most every "wattmeter" in the world measures a combination of F+R when measuring forward power.  So if it reads 800W, actual forward power is likely 464W (and reflected is 336W).  Happens with every meter I have.  Bird dedicates a page in their Thruline manuals about this.

I believe that he is getting some kind of meter to tell him that he is getting 800 watts output. I doubt that he is. I don't know of any commercially available wattmeter that is accurate when the SWR is so high.
