Hi Martin,

Awhile back my son installed a set of those hand-capacity sensor lights for us here beneath the kitchen cupboards---they are quite nice-looking when activated, & are the type that if you touch the sensor button three times in succession, the lamps' intensity will increase accordingly...

I found the very same thing here: on any band, my RF would trigger the lights to activate, and when they were "on", the RFI in my receiver was terrible.

The only cure that I am aware of---and it works for me---is to COMPLETELY UNPLUG the lights from the AC mains before an operating session in the shack. When I first brought this subject up some months ago, I do not recall reading of ANY "fixes" beyond that, unfortunately...

...Hardly the sort of news that you'd want to hear when it's a neighbour being affected, surely, but that seems to be the nature of the beast, sadly...
