[Yaesu] FT-990 again...

[Kjell W. Strom]

Hej Östen,

How did you come across a Belgian version? I think that jumper JP5001 may be
the solution. You will find it on the Control Unit, where it is connected to
Pin 48  on the CPU Q5004. In the real world it is located next to the Filter
Switch, refer  to the photo at the lower left of  page 46 of the Operating
Manual.

If there is a solder blob on JP5001, remove it and proceed to adjust the
power like  Thomas described.
