Interference question

[Jeffhs]

The house I grew up in had a dimmer on the lamp above the kitchen table in the dining area. I never had any issues with RFI from that dimmer, none at all. This was the only light dimmer in the house, the other switches being standard on/off switches. The dimmer on the lamp in the dining area never gave five minutes worth of trouble; in fact, if I remember correctly, that dimmer was still there when I moved to my apartment, 21 years ago.

I don't know what happened to the dimmer after I left the house; my best guess, however, is it may have been replaced with a standard on/off switch or perhaps another dimmer. I have absolutely no idea at this time what happened to the dimmer (or to anything else in the house, for that matter), as when I left the house for good in 1999 I did not look back.
