Hi.

I've seen this effect before.  The transmitter might not actually be 
putting out more power--the meter is just reading high under that 
particular load.  I used to have a Radio shack SWR/Wattmeter on my old 
Heath HW16 that would show 100 watts out when I would run a high SWR.  I 
could see the plate current and could do a simple calculation of plate 
voltage times plate current to tell that it simply wasn't possible, but if 
I ran about a 3:1 SWR, that meter would read high every time.
