The dimmers can be a problem. THey used to be terrible, but some are
quieter now. With the HF noise floor varying with time of day, etc - you could raise the noise floor somewhat, and might not notice it for a while. Some of the screw-in flourescent converters have oscillators near LF, VLF band. These can be bad too... How about under cabinet and overhead florescents? They use considerably less power than halogen too.. With anything you consider..i'd run some tests with the same model he plans to install at close quarters to your rig. Wrap a wire around the bulb or tube..and connect to the receiver antenna.. Turn the light on and off... Hear anything??

He also has suggested halogen under cabinet lights. All of these lights would have dimmers installed. My question..Has anyone ever had these put in, and do they generate much interference. I know I have a halogen light near my rig and it generates lots of hash, but the shack is on the third floor and the kitchen on the first. Any ideas about the QRM? thanks Kevin W1FWB |
