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

I have a table radio that's pretty much all noise, all the time
on
MW, where I am. Ferrite rod antenna, and no real provision for
ground.
I connected an earth ground to the sleeve nut on the headphone
output
jack and that quieted things down dramatically.

Works on some of my other receivers as well.

Peter, did you run an earth ground from the outside for it,
I presume?
