As an amateur radio operator, LEDs have been the absolute bane of my (and thousands of other city-based hams') receiver. Those same modules not only produce ungodly amounts of heat, but also loads of radio-frequency interference that has been contributing to the increase of the global HF noise floor over the last decade.
And it's not only hams, but also other radio spectrum users, like mariners -http://www.professionalmariner.com/December-January-2019/Onboard-interference-from-LED-lights-called-huge-safety-issue-for-mariners/ http://www.professionalmariner.com/December-January-2019/Onb...
- jandrese 8y agoAre they worse than CF bulbs? Those seemed like they should have been a nightmare for RF.
- xxs 8y agoDepends, some of them are run at around 22KHz... so it's quite appaling
- DoctorOetker 8y agoI think jandrese is referring to the fact that even a DC current through a plasma generates loads of RF, for example fluorescent tubes emit THz radiation!
