Re: [Elecraft] [OT] Street Lamps and RFI
I don't think so Jim, but don't put any money on what I think. Most of 47CFR that deals with such standards seems to classify emitters based more on their usage rather than location. I suspect that "street lighting," even if in a residential area would not have to meet Class B standards. Not that that would matter anyway, it appears that no one is enforcing any of this. 73, Fred K6DGW - Northern California Contest Club - CU in the Cal QSO Party 1-2 Oct 2016 - www.cqp.org On 6/9/2016 9:57 PM, Jim Brown wrote: On Thu,6/9/2016 5:46 PM, Phil Kane wrote: Although we wish that it would be so, it is very doubtful if there are any street lamps that are certified to meet FCC Part 15 standards as Class B devices.

Could the ARRL help? Maybe they can provide some background or educational material for the association.

Re: [Elecraft] [OT] Street Lamps and RFI
My experience with two [a small sample] of street lamps, both owned by the State of California [CALTRANS], is that the lamps don't really matter much, it's the controllers ... what we used to call ballasts but that's archaic now. One appeared to be a fairly old high-pressure sodium vapor lamp, and it emitted a steady buzz centered on 6 Mhz and spread from about 3 Mhz to 8 Mhz. It was about 3 km away and ran about S5-S6 on my K3. A similar lamp maybe 4 km distant emitted nothing. The other was what I believe a low pressure lamp. It's problem was that it was failing ... very, very slowly ... and the controller [or ballast, your choice] would emit sharp spikes in a spectrum that ran from 160 through 17 m as it continually tried to restart the lamp. After multiple contacts to my state government, I gave up and we finally moved [not because of that :-)]. The failing one has not yet died, saw it last time through Auburn ... it does this day and night. You might want to point your Association to 47CFR15, and their responsibility to prevent interference to licensed services. They might care about that, CALTRANS never did. 73, Fred K6DGW Sparks NV Washoe County DM09dn On 6/9/2016 2:43 PM, KarlErb wrote: My condo association is planning to replace 1960's street lights to reduce energy usage.

Re: [Elecraft] [OT] Street Lamps and RFI
This is a reply from Mike Gruber -- Phoenix is planning 90,000 street and park lights - Hank K7HP To Whom It May Concern: This is in response for your request for public input concerning a conversion to LED street and park lighting in Phoenix. Although these lighting devices must meet FCC Part 15 limits for unintentional radiators, I’d like to suggest that they be rated for Part 15B as opposed to Part 15A. The lower Part 15B limits would help minimize the interference potential to radio reception in automobiles and other nearby users of the radio spectrum. Please don’t hesitate to ask if you have any questions.

Re: [Elecraft] [OT] Street Lamps and RFI
Karl, It might interest them to know if the street lamps (or any other devices) create RFI to licensed radio services (Amateur Radio included), they must turn those devices off and rectify the problem. Of course, the FCC would be involved should that happen, but they must rectify the RFI problem in any case. They may not understand why it matters to them until you make a complaint to the FCC and they are asked to shut the RFI generators down. Caution, the enforcement process can take some time, so if you can steer them to RFI-free devices, that is the best solution. I don't have any pointers to RFI-free street lighting. 73, Don W3FPR On 6/9/2016 5:43 PM, KarlErb wrote: My condo association is planning to replace 1960's street lights to reduce energy usage.
