that would be the chip in the meter not reading things right.
When the swr is high, you can get really wonky power readings...when my swr 
is at say 25 to 1, my transmitter is apparently putting out 257 watts...
once you get the swr into the acceptable range, below say 4 to 1, the meter 
will become far more accurate regarding the forward power, and it'll be dead 
on, or at least within 5 per cent each way, when the swr is 1 to 1.
the LDG tw1 is particularly bad for giving rediculous readings of forward 
power when the swr is high.
