- Based on the recommendations from members of the reflector, I ordered Hyperikon 4Ft and 2Ft LED tubes to replace my fluorescent tubes. I thought I would pass on my results. My main reasons for replac

- Thanks for your work and your post, Jeff. There's one VERY important problem with your method in attacking devices like this. Your method is great for power line noise, which is impulse noise, and th

- Thanks for the clarification Jim. I think the RF energy is present in both. Depending on the turn on time of the device, that will generate noise across a wide BW, similar to what a lightning pulse d

- No question that it's an SMPS. Yes, products are harmonics of the switching frequency, but many factors affect how their their strength varies from one part of the radio spectrum to another. By far,

- It is really hard to establish correlation with noise a few feet away from a noisy device and noise to a much more distant receive antenna. In many cases, if noise is coupled differentially onto the
