[HiDARG-MEMBERS] OK? Street lights to LED's project in Bend.

[Dave Freitag]

I held off a long time before replacing my incandescent lights with LED lights, worried about noise QRN in HAM reception.  Each LED light has a switching power supply, with spikes extending into the VHF spectrum. I have a small fortune invested in ferrite chokes to reduce the common mode conducted noise.But my power bill was reduced by 20 %.Dave, W7KFOSent from my Verizon, Samsung Galaxy smartphone

No mention of that subject in the information pages put out by the city.They probably never heard of such a thing. They're just concerned with green house gases. \JoeOn Tue, Aug 13, 2019 at 5:06 PM Max Vaughan <maxv at horizonps.com> wrote:As some of you may or may not know… Bend is replacing all their street lights with energy efficient LED’s…Question is…. are they more RF noise producers, than the sodium ones?I need to find some of these lights and do some scanning on freqs… to determine RF noise levels.For the FAG sheet…. see this link. https://www.bendoregon.gov/home/showdocument?id=42341 73Max Vaughan KF7MAX  SecretaryHigh Desert Amateur Radio GroupPO Box 723Bend, Oregon USA   97709 541-706-1475 www.hidarg.org  maxv at horizonps.com  kf7max at arrl.net    _______________________________________________
