If you mean that the meter shows extra high power on frequencies for which the
SWR is high, this is an inaccurate power reading caused by the meter's being
designed to work properly only on a relatively flat (low-swr) line.
If you mean that the swr reading goes way up as the power output of the amp is
increased, then this might be an indication that the harmonic output of the amp
is very high when the amp is tuned for high power; the swr of the antenna system
at harmonic frequencies is probably very high.
