HW-9 Low Power

[Jan Eliasson, SM7NDX]

Hello!

Still no success with my HW-9 on 40 meters. It seems that the 40 meter
signal disappear just before or inside the band pass filter at the T/R
Board.

My other question is about low power on 17, 15 and 12 meters. Only 0.5 W. I
can measure 6-7 Volts at all bands (except 40 meters) at test point TP at
the T/R board with the "internal RF-probe" and a VTVM.

The HW-8 Handbook says that low power on 10 and 15 meters can be solved with
changing capacitors C563 and S566 in the low pass filters. These filters are
the same for 17 and 15 meters and for 12 and 10 meters. Is this the
solution?
