Hi, I have a house full of CFLs, too and no noise at all. I also have a number of fluorescent tube lamps. Most of these have conventional magnetic ballast but a few have electronic ballasts. No noise from either of them either.
More recently I went out and bought two 60W (incandescent equivalent) LED lamps from 2 different manufacturers. Rumor has it that some of these are extremely noisy. But I have no noise from them either, much to my relief. I do have a recent noise problem that affect mostly 40m and vicinity. On the panadapter it shows as "humps" 10-15kHz wide and spaced about 40kHz apart. It sounds like a scratchy noise and it drifts slowly. Folks on the LP-Pan Yahoo forum have suggested it's a washer or drier, but who is washing and drying 24 hours a day? If it is a motor control, it must be some motor that is running more or less continuously. Unfortunately I have a difficult time arranging an antenna on the car with reasonable efficiency on 40m, so I haven't been able to sniff around the neighborhood.
