[Hallicrafters] I bet you knew this already.

[Jack Dunigan]

My radio bench has one of those magnifying lights in which I put one of those curly, energy saver bulbs. It is bright, runs cool, and supposedly saves money. When I fire up my Hallicrafters S38-C and turn on the light, a terrible buzz obliterates all signals on the lower half of the broadcast band. From about 900 khz down absolutely nothing gets through. When I switch off the light, the radio works normally. You all probably knew this already, but I was preparing to tear down the radio, replace filters, change tubes, and the like. Glad I switched off the light. Then I discovered that the radio is affected the same way by another lamp in the room maybe 6 or 7 feet away with a tubular quartz bulb and a dimmer switch. Changing the dimmer changes the tone and intensity of the interference. 

Is there an easy way to filter this out? Incandescent lamps in a ceiling fixture seem to have no effect at all.
