That's right Bob. For driving a transverter or any other device that
only needs a minimal amount of drive. I think it is pulling the RF
from the driver transistors before it gets to the final PA transistors.
I've heard of others doing this, so it is something we should keep in
mind when the rig doesn't seem to be working right.
