The problem is likely to be low frequency noise coming out the AC line cord. I would buy a high performance AC line filter for a few buck; /archives//html/RFI/2006-06/msg00001.html (9,249 bytes)

The path is out the long AC power cable. Twisting the wires won't help the unless there was an unlikely huge design oversi; /archives//html/RFI/2006-06/msg00002.html (12,345 bytes)

There is a tremendous amout of noise coming out of the front panel, all across the HF and VHF spectrum. Surely there is AC line cord radiation as well.
