On the 42-400, I get a hum only on the strongest station on the dial. It completely goes away when I turn the antenna just slightly. This is mildly annoying, as four of the presets come in perfectly without touching the antenna, then for the fifth (and strongest station), I have to pull the radio away from the wall, and just move the rotator a little bit. Tried to adjust the preset oscillator and antenna, which works, but then the volume isn't as loud as the others. It seems that it is picking up the hz cycle from the wiring in the wall at that particular frequency. (Perhaps there are wires not exactly grounded properly at the outlets, or a neutral is reversed in this old house?). I came to the conclusion that a different location in the house would solve this problem (as it never hummed at all out in the garage-even with the fluorescent lights running!). Keep us posted, Eric.
