Radios in office buildings, and general radio interference

[OvenMaster]

1. I have bad indoor interference on AM on my Yamaha T-80 here at home, thanks to computers, VCRs, TV sets, and my PC's battery backup. There are only four solutions that I know of for this problem: shut off the devices causing the interference, move the radio away from the interference, put the radio next to a window, or have an outdoor antenna with a shielded lead-in, where the shield is grounded. The first two are out of the question. The third may be impractical. The fourth one worked when I had to have an outdoor longwire feeding my shortwave radios here at home to kill off dimmer and oil burner noise.
