Before it gets cold again I will likely be replacing my old gas furnace. I am looking at the high efficiency models, probably one with just a two speed blower rather than a variable speed one. Any RF

I recently acquired a 2007 Honda Fit. It has several problems with RFI, one of which I find particularly puzzling. There is a broadband noise, spaced every 20 KHz. It can be heard from 40 though 2 me

But if some of us purchase hybrids to promote the technology, which should improve. Otherwise they're going to generate RFI, which I think is the point of this list? I expect far less RFI from CFLs t

Are the alarms indeed false? Have you tried a second detector, preferably not a Kidde Nighthawk? It sounds like you have a detector. Can it be moved/traded with your neighbor on a trial basis? 73 - J

What explosive gasses does that Kidde thing detect? Low levels of methane? Flatulent emissions? Perhaps you need to supply your neighbor with some Beano. 73 - Jim K8MR In a message dated 11/14/2007 7

Last August I bought a new 2007 Honda Fit. While the ignition noise seemed reasonable, especially after adding a few easily done exhaust pipe grounds, there remained a mysterious broadband noise noti

A few more details, omitted for brevity in my first post: While the noise is present everywhere, it is not truly broadband. Listening at HF with the IC-746, it is a series of broadband signals spaced

It sounds like basic RF overload of that preamp. Does the interference arise when transmitting on other bands? Are antennas for other bands as close to the TV antenna/preamp? First I'd try some ferri

So the preamp is inside the house? My question is whether the RF is getting into the preamp by common mode (outside of the coax) or differential mode (picked up by the antenna and sent down the insid

One other thing to watch with preamps: even though the TV stations may be distant, close by FM stations can overload the preamp and cause problems. This may be especially true for certain high band V
