For One and All,
Here are Two other Alternative Methods of establishing
and using an RF Ground with a 'portable' AM / FM Shortwave
Radio; that has NO External Antenna Input or Identifiable
Ground Connection.
BATTERY TERMINAL :
Most of the Times the Negative Terminal (Side) of the Batteries
is the Chassis Ground of the Radio and is both Power Ground
and the RF Ground. If this is the Case then a Washer with a
short piece of Insulated Wire soldered to it can be used as an
easy RF Ground Connection for the Radio.
CASE SCREW :
Check the Case Screws with an Ohm Meter to the Ground
Side if the Radio's Circuit. Usually one of the Case Screws
will be connected to the Chassis Ground of the Radio.
Remove the Case Screw and wrap the striped end of a
short piece of Insulated Wire around it; then re-install the
Case Screw. This Wire is now your RF Ground Connection
for the Radio.
when all else fails - think of the possibilities ! - iane ~ RHF

You are a dork. If the cabinet is all plastic it's because it ain't
suppose to be grounded. Only ground the external antenna input. Your
obsession with ground is borderline pathological.
