Rick,

This isn't normal.  I often see the opposite:  Maybe a 1.4 swr on a band at 
low power and  see it drop a few points at high power.  Does it happen on 
all bands?  Same result into a dummy load?   Did it just start doing this?

I may have you confused with someone else, but didn't you have a problem 
with intermittent high swr on a vertical antenna not too long ago?  If it 
was you, what was the final result and is it the same antenna  you have 
problems with now?

Easy thing to do right off is to check all connections in the shack:  rig, 
meter, tuner, amp, switches, etc.
