[Icom] pwr IC746

Hi,
In SSB mode, it has lot to do with operator's voice characteristics.
Unless there is malfunction inside radio, knowing input power is all I 
need at least when I am
concerned. Nevertheless, I am 99% CW guy. I can swing my bug all day 
long, I can't talk even
for an hour without losing my voice, hi.
73,
