Byron, I have successfully moved a 375 watt station down to the 147
region. Check that
your exciter is putting out the required drive pwr in the ham band. It
was a long time ago
but I think I converted the exciter into the lower band by just
replacing the components indicated
in the parts list. (the parts list shows frequency sensitive
components). I don't believe
any conversion was necessary for the AMP but the conversion was done
about 20 years ago.
By the way, that's excessive power. We run ours well below half power by
turning the screen
control down.
Good luck. Joe
