[ARC5] Hallicrafters S-38 - ground symbols

Well, I dunno about that: I have always
viewed the "fork" symbol as meaning 
a direct-connection to a metal chassis, or
to a sort of electrical "sink", or 
common, and the conical-looking one as a
connection to the earth, the 
dashed-lines representing something buried
underground.

I think that's the way I was first shown it, Ken, but after lots of exposure to ARRL pubs & some others I came to accept the conical looking one as a local common (that may or may not also be connected to an earth ground) unless otherwise indicated in the diagrams.
