No, wasn't aware of that. It's been a while since I've delved into the K3's
menus.  Do you know what that option is called, or where to find it in the
manual?

Also, just to make sure I'm understanding you correctly - do you mean to
suggest that if the K3's watt meter reads 5W, but actual output power is
4.5W, you can adjust output power to match the K3's meter?  As it is, the
K3's meter and LPA power settings do not match the readings displayed on my
outboard analog and digital forward power meters.  When the LPA is in use,
displayed power is always a .5 to 1 watt lower on the external meters.
