Karl sent me a photo via private e-mail. I opened and
looked at my S-38 and it does not have the wire he
indicated. The wire goes from the antenna tank section of
the bandswitch to the RF grid of the converter tube. The
schematics do not show any other connection to this point
nor is there any sign of on in my RX. I can only speculate
as to why this wire was added. Hallicrafters made almost
continuous changes in the details of their receivers so its
possible this is a factory job but I doubt it.

Could this have been somebody's fix to work around a bad rf coil?
