Incredible noise tornado on 16om

Has anyone ever seen anything like this? It seems to be there 24-7.

Yes, but I haven’t found the source. Mine is also on 24-7, drifts 100 kHz or so, and has multiple humps.

Hi Vic -

Does it drift around any? Do you still see it if you use a length of wire in
your house for an antenna? If you go to a park and string up a similar
length of wire, do you still see the same delay? Chances may be good its
some electronic device(s) in your house or very near you.

G'Day Gents,

Do you both really mean 24/7?

If so, what does that say about source location and/or power?

I think you are both Beta testers. Perhaps some new software for P3 or K3?

73,

Re: Incredible noise tornado on 16om

It is also characteristic of the RFI produced by "touch control"
devices, as used for lamps and such. Have you powered down various
circuits in your home to see if one of them is the culprit? I have had
touch-control RFI from as far away as several houses distance. Another
source of this type noise is proportional-control aquarium tank heaters,
also battery chargers. Drifting frequency is often a give-away of
interference from a touch-control device.

Can you hear it on a battery powered portable AM radio? If so, try
walking around your house and around your neighborhood. The loop
antenna inside the radio will give good directional indication when
pointed at or 180 degrees away from the noise source. Test on an AM
radio station of known direction (preferably from the next town) to get
an idea of how to interpret loop patterns.

Let us know what you discover

It looks like what we suffer from in the uk on the ham frequencies, OTHR or over the horizon radar.
In eu, It pops up whenever and believe it emanates Asia or Cyprus.
But in your case in CA not sure on its absolute range!!

Re: Incredible noise tornado on 16om

The RFI that we are seeing is present all day, every day, at a consistent level. That suggests that the is local, not remote and arriving via “sky wave.” Vic is in California; I am in New England; we most certainly hearing different sources with a shared RF signature. I’m hoping that signature can help narrow the possibilities, if anyone recognizes it.
