The P3 shows total forward power. The power delivered to the feedline
is forward minus reflected.
With a 13:1 SWR, 73.5% of the power is reflected and 26.5% is
transmitted. If the transmitted power is 92 watts then the total
forward power should be 347 watts.

I placed the DCHF-200 after my antenna tuner. In other words, the
DCHF-200 is between my tuner and antenna. When relying on my tuner
to match the antenna to the radio My power meter (on the P3) is
showing an SWR of a little over 13:1 (which is about right) . My
meter on my tuner is showing about 92 watts of power headed down the
antenna,but the meter on the P3 is showing over 200 watts. My
intended output being 100 watts. Does the DCHF-200 show out-going
pwr + reflected pwr? The tuner matches the antenna to the radio, and
the tuner meter shows a very very small amt. of reflected power. I
put the DCHF-200 at this location, because if I had the tuner
installed in the radio, this is where it would go.
The antenna is a fan dipole trimmed for 40 meters and 20 meters. I
am on 3.810 MHz and without the tuner the SWR is about 13.2:1 here.
The tuner matches the antenna to the radio with a SWR of very close
to 1.0:1. .
