Why does my SWR reading increase when I increase power? For example, on 40M
at 4 watts into my untuned 130' dipole, SWR reading, both on my TT 580
Delta, and on outboard Kenwood meter is abt 1.2, BUT, if I increase power
to, say 80 watts, My SWR will go up to about 2.5+. I can tune the ant. to
bring it back down, but why does it go up with power? Will I blow my finals
if I continue to run at 4 watts to untuned ant with both meters reading 1.2?

Many thanks,

Steve in Maine KE1LG
