Here we go again with horrible noise on my radios 🤬

[Falcon9h]

I'm in a world of getting completely wiped out:

Pulsating noise, all charges and other electronics in the house are unplugged. This truly sucks.
Anyone else have/had the same thing? I'm pretty sure that it's coming from outside the house or down the power lines.

Thanks 👍🤞

Not familiar with that radio, but if it runs on batteries, I always turn off the main breaker to ensure it’s nothing in my own home.

Did that also

Did that also

If you have done that and experience the noise, it is coming in via the antenna, and not the power source.

Of course, it could be coming in via both avenues or inside the radio too.

Have you taken that radio, assuming it runs on batteries, and walked the perimeter of your property to see if it weakens or strengthens in any particular location. It may not solve the problem but at least it may give you a better idea of the origin. It is amazing what can generate noise. My neighbor was leaf-blowing with a gas powered blower and it raised my noise level on HF and a bit even on VHF.

I'm not sure if that radio has an external antenna input but maybe a passive loop antenna might help. I have an active loop here and it does wonders for my HF reception overall, but an active antenna of any nature would likely overload that radio.

Any solar panels in the neighborhood? Does the noise ever stop?

 

[brandon]

Sounds very much like what I experience on anything less than 8 megs during daylight hours. I'm leaning towards solar panels as well.

Man. That would be irritating. The most bizarre noise I experienced was a neighbor's washing machine, from about eight to ten houses away. the RFI travelled down the power line for about 200 feet, using it as an antenna/radiator. It would wipe out various channels in the 40/41 meter bands and a bunch of individual frequencies below. Sounded like an alien firefight. Luckily it was only once every other night or so.

Since then I've been lucky, I guess.

Feel your pain anyway. RFI can really suck.

I had some weird interference when I lived in North of Tallahassee. It was a narrow carrier in the 150 MHz range that sounded like alternator whine going up and down in pitch. The weird thing was it never went away. I finally concluded it was some sort of motor controller for a water pump system. I really never knew for sure.

Oh, that is nasty. I haven't heard that sort of fast periodic sweep on a PWM/switched mode controller before, although it is quite possible I suppose. From the sounds you are showing it looks to me like a comms system of some sort, perhaps carried on the power lines? Can you safely couple a spectrum analyser of some description (an SDR dongle would suffice in this regard) to look at what is going on over a wider range?

 

[GeraldP]

A little more info, please.

Is the noise on one frequency or completely across the spectrum?
Have you disconnected the antenna to see if it is a received noised or generated within the radio itself?
Have you changed the location of the portable radio to a neighbor's house or some distance from your home?
Do you have remote metering on your house's electrical (power meter)? They sometimes emit interference.
God Luck!

Is that the Japanese version of the Sony 7601 ? If so, it runs on 4 AA batteries too. So if it where me I'd take it outside and walk around the neighborhood.

Clandestine (or otherwise) Grow Light Ballasts. I had a personal experience (back in the day) in being bird dogged by a local ham group. They zeroed in on my location. Nice guys. They were complaining about the same issues mentioned above in previous posts. Just a thought.

 

[W5ATX]

sounds like a washing machine or dishwasher, time to start hunting!

 

[Falcon9h]

It's very weird... the noise will speed up in cadence, then slow, then it shuts back to a sound like it's idling, then pick back up slowly and come back to the original sound as posted.

No spectrum analyzer-I'm broke. 🙄
Radio is completely analog, using batteries only. Intensity of noise varies walking around but I can't pin it down.
Definitely external to the radio. Hasn't bothered me for the past couple days. But on some days I get desperate, say the hell with it and stream the station I want to hear into a milliwatt FM transmitter and listen on another radio.

 

[oldradioguy2010]

Could that possibly come from the, yes solor panels, or the switching unit that takes the solar to the commercial power?
As I know, it has a sweeping to control between the two power sources.

BTW
What frequency are we at?

[Falcon9h]

Falls in the middle shortwave freqs 5-12 mhz. No solar panels in the neighborhood that I'm aware of but don't know for sure.

 

[oldradioguy2010]

Ok Falcon,
Just for a ha ha.
I too will poke around there.
We have panels, but never heard it.

Record times dates and audio and get the FCC involved! Thats what our taxes pay them for.
