[Icom] IC-735 low power output

Ed:
    If they use any diodes in the selecting of the band pass filters, then
you likely have one or more bad diodes which may leave one of the band pass
filters on all of the time. You have proven that by going directly from PA.
So likely it's the one selecting the 10 meter band.  73 from Fern
