[1000mp] Q: Antenna Tuner, FT-1000MP Mark V Field

I remember reading in the manual or an errata that
the internal tuner will not reliably tune a Windom
antenna.  Anyone else remember reading this?

I use a Windom antenna for 40 -10 m.
Acc. to specification it is not usable for 15m.

When I try to tune the antenna with the installed
antenna tuner, the result is HiSWR and the
transmitter
is shut down.
pwr adjustment is max. 100 watt.
With this adjustment it�s not possible to bring
the antenna at
15m to a acceptable swr.

But when I adjust the pwr adjustment at the front
panel
to about 20 watts, the tuner works and bring the
antenna to
a good swr, 1,2 : 1.

When I now adjust the pwr adjustment at the front
panel
to max. output 100 watt, the swr keeps the same
value as
with 20 watts.

Question:
Why can the tuner not tune the antenne at max. pwr
adjustment
at the front panel ?

Is the procedure to tune the antenna with the low
pwr adjustment
and after tuning to got to 100 watts ok ?

At all other bands, were the antenna is in
specified range, the
tuner works very well at the max. pwr adjustment.

Thanks for helping!
