Most of the time it is, yes. The magnetic ballasts generate a little bit of harmonic interference, but the "electronic" ones are far worse, since their switching times are much faster. The magnetic ones are the reason I don't operate on HF much these days. (aside from that whole lack-of-spare-time thing) There are ~380 eight-foot fluorescent light bulbs in the building. :-( -Dave On 03/10/2016 02:37 PM, Dean Notarnicola via vcf-midatlantic wrote:
Granted, but is it worse than the awful RF noise from florescent ballasts?

No, not at all. Weak signals from other continents are often completely obliterated by interference from LED, CFL, and standard fluorescent lighting. The inverse squares law applies to the desired transmissions too, and they're coming from a lot farther away that across the street.
Two words:
Faraday cage
Then we could get Tempest certified too ;-)
YES!!
