HF Noise

[KC2UGV]

So, I just moved my antenna (Due to moving my shack, don't ask), from the back of my house, to the side.

While, it's been a few months since I've had my HF rig on (Life being what it is), I just got it all going today.

And, DAMN. RFI.

It's a noise from 40 meters to 10 meters, at about 1 beat per second, and crosses the entire band. And, like S9 across the whole thing.

So far, I've ruled two rooms out in the house, but what should I be looking for as a source? I know generally certain items sound the same. If an audio clip helps, I can get that.

You didn't, by chance, end up closer to a plasma tv? What if you temporarily take it back where it was and see if the noise is gone?

I don't think so, but at this point, I'm assuming it's external to my QTH... It doesn't sound like a Plasma TV (According to ARRL samples), but I could be wrong. I suppose I could try that in the morning (Moving the antenna back).

First thing to do: Put the radio on battery power and kill the main breaker. If the problem goes away, then the issue is in the house. Be sure to disable any UPS you have first.

Do you have anything that can RX at 6m in AM or SSB modes?

Unfortunately, no 6M RX (Unless TV counts). I am however, going to kill the main breaker in the morning, however, I don't think it's interlal. My troubleshooting spideysense thinks it's the new neighbors.

But, that's a reason to meet them :)

They don't ride motorcycles, do they? Cue TZ music.

Does the rf meter move with the one beat per second 'tick'? My daughter had a rock polisher that introduced a slow tick noise in the line. I was unaware of it's presence until I fired up the rig.

Discharge threshold for some sort of HV device as it reaches breakdown? Arcing transformer? Electric fence charger or bug zapper? I can think of a number of devices which would do this.

As Jim suggested, eliminate your house as a source first. Next, get a handheld AM radio with a loopstick antenna - which is somewhat directional - then go hunting.

They do... And wear leather jackets...

It does, actually. No rock polisher, but that's the line I was thinking: A slow motor (Like a ceiling fan, or dryer).

Some heaters do that, water and house. Other appliances as well.

Do you have an HT with wideband RX thru the shortwave and VHF bands?

I've used my VX-5 to find noise sources in AM mode...
