	I ran into a similar problem when I used an antenna about 50
feet above the shack.  This particular keying box was built with twisted
pair cable.  I have another box that uses a shielded cable and the RFI
problems go away.  For some reason the shielded box would not key the
ptt line so I had to use the old box.  Good thing I did not need the
other antenna!
