I had phase jitter a number of years ago resulting in harmonics. 
Fortunately, one has moved out of the house now and I only have one left. 
I cannot explain how it happened here, since this is a family oriented
site.  However, it happens less frequently these days - and the risk of
harmonics is very low.
