I've converted my entire house to CFLs. I have probably half a dozen
radio-controlled clocks. No problem with them. No problem with operating my GPS
receiver indoors either.
The only thing that bothers my radio-controlled clocks is this Dell Inspiron 4150
laptop. If I don't remember to turn it off at night then none of the clocks nor my
watch set themselves.
