[RFI] LED Street lights

[AA5CT]

 I don't know where you're coming from Jim. How long has it been since you've been in the 'field' with a portable SW receiver? 


Noisy devices, power poles, even lighting poles all have distinctive signatures heard when standing near them. The CLOSER you get the STRONGER will be whatever noise/signal the device *may* be generating. Surely this aspect need not be spelled out? 


I still stand with the advice as a first tier investigation to GET NEAR THE DEVICE and inspect the ham bands for any anomalous noise. This isn't rocket science. This e-mail was a response to Eric for advice looking at a NEWLY installed LED lighting pole. Eric, if you have a SW/HF radio in the car that might be a way to do a first tier/first pass inspection of the new lighting pole too.

Not all noise is broadband. Indeed, most electronic noise is not. And 
the receiver cited makes an excellent spectrum analyzer. Most noise is 
radiated by wiring, not by the fixtures themselves.

NK7Z's webpage provides lots of excellent troubleshooting advice for 
chasing electronic noise.
