From what I've understood form Ed Hare, "harmful interference" is defined on a case-bay-case basis. I don't think we want a hard and fast limit, to be honest. What works in one case may be a disaster

Do you mean -120 dBm? How do you measure that? At what point is the radiated power measured? How do you connect to a device to measure it? Besides, why stop there? Why not simply make it *undetectabl

My wife has been interested in increasing the efficiency of our air conditioner units. It seems that the only path to better efficiency is multi-stage/multi-speed units. I recall a lot of talk about

My understanding is that the RFI is generated by the variable speed motor controls. In these systems, both the compressor and the forced-air run at variable speeds. Which is the main contributor to t

It seems that I may have used the wrong terminology, as the latest approach to this is "variable speed compressor," where the compressor speed is varied. Looking briefly into this, I found that some

A two-stage unit probably wouldn't help much here in OK: we often see stretches of a month where temperatures are close to (or over) 100F with high humidity, usually across July and August. We easily

The paperwork calls it "two stage" but it's all the same thing. A one-speed unit is quite capable of the job as well, since that's what I have, but not as efficient and not as effective at keeping th
