If that helps, it's being radiated by the power cord, If i; /archives//html/RFI/2008-05/msg00004.html (7,023 bytes)

Unless there have been some major changes in microwave design very recently, the commodity status of this device has relegated it to a; /archives//html/RFI/2008-05/msg00005.html (9,346 bytes)

That sort of says radiated rather than conducted to me. The microwave was a wedding present, so it is at l; /archives//html/RFI/2008-05/msg00009.html (8,073 bytes)
