every single night (including weekends) around 2am (usually at about 1:57am) pacific time, I hear very strong and loud radio interference on my home speakers. I have even heard it with my computers and other electronics (including wireless laptops, phones, networking equipment) switched off.
the sound is a strange "zooming" or "phasing" in and out sound at high frequency. it goes on for roughly 5 minutes before fading out. there's nothing going on outside my house besides a milk factory moving truck trailers around in their parking lot.
repositioning my speakers has no effect. this happens on all speakers in my house and in my cars (if they're parked at home).
the noise doesn't really bother me, as I'm usually up late working anyway. what concerns me is that if the signal is this strong, it must be interrupting other important services such as emergency broadcasts.
what can I do to figure out the source? should I bitch to the FCC?
dems come to get you but you not asleep.

dude when I first heard it, I got a little creeped out... it literally sounds like what you'd imagine little green assholes ships sound like.
but seriously it's probably some other weird shit like local police meshnet boxes resetting or whatever...
>>51978192
I did and they just accused me of lying. lol.
I don't think it's paranormal, that's why I posted here.

hard to hear it -- to the naked ear it's loud, but my phone only picks up half the frequency.
promise there's no screaming or 2spocky4me surprise:

could this be something as dumb as powerline communication? it literally is every night just before 2am... on schedule.

>>51978320
let me see if I can clean it up. like I said, it's REALLY obvious in person but I've had trouble capturing it.
>>51978330
yes, I know. I am wondering what the fuck it is though - it happens every day on schedule, on every speaker near my house. I've even driven down the street and heard it for a few blocks in any direction.
>>51978294
I actually heard it.
I'd be creeped the fuck out if it happened to me at 2AM.
I have not got a clue what it could be though, sorry anon.
>>51978320
>>51978347
I cleaned it up... in audacity, I sampled just the background noise in the beginning and did a simple noise removal with default options. then I amplified by 20db.
warning, it got super fucking creepy now.
http://vocaroo.com/i/s1I8xfld6joF
Looks like you need some audiophile grade cables and cable lifters, anon :^)
>>51978393
Is that more of what it sounds like in person? Before it was just a faint sound but if that's what it sounds like without background noise, I wish you luck anon.
>>51978434
yeah. it's like a garbled in/out wooshing/churning/zooming/phasing
I don't know how to describe it outside of the audio I uploaded.
like I said, EVERY night just before 2am, then it's gone just after 2am. 5 minutes every time. I've had friends over who heard it and refuse to come back over at night because they think my house is fucking haunted. lol.

>>51978224
If it's not aliens, do you think it's top secret shadow government stuff?
>>51978448
best way to recreate the noise:
move your lips like you're making an ambulance/siren noise, but don't use your vocal cords...
then inhale sharply as if you're whistling backwards.
that's what it sounds like to my naked ears.
it's on multiple "frequencies" / pitches like a mixture of a whistle and a voice and uhh wind?/breeze?
my old logitech speakers always received radio transmissions, annoying as hell.
>>51977638
Where do you live?
>>51978451
my serious 100% not joking guess is it's something powering on or scanning every night... something with either enough power to create a radio signal, or something with a transmitter (like satellite or actual radio).
the city / someone recently installed a large white box with antennas on the power pole in front of my house. I assumed it was a mesh network for the police/EMT but who knows? (pic related) -- there was actually a big story about this, as it was supposedly funded by homeland security.
since it happens with my power off, on any speakers (even headphones) I am positive it isn't coming from my house or anything in my house.
>>51978485

>>51978490
if you craft a smaller disturbed device to a satellite dish you could try to pinpoint the source
pretty cool m8
>>51978504
Great, now I'm even more spooked than I already was.
years ago used to have a guy with a illegal power amp on his cb and when he drove pass our house you could hear his transmissions right through the speaker wires. it would start off really soft and get louder as he came closer then fade off as he passed by. always happened at a specific time since he was coming home from work while gabbing on his cb. guess he got into trouble since it one day it stopped happening.
>>51978338
It's the government reprogramming you.
>>51977638
yes, this is something the FCC could be very interested in. ask them about it, and if it's something that they might be able to investigate but don't bitch about it

Probably this, some delivery truck driver is using a jammer to stop their employer from tracking them.
>>51978490
It's probably a radio signal all right. Maybe other electromagnetic interference.
Finding the source by triangulation might be a pain and I don't know any general purpose devices to do this. https://en.wikipedia.org/wiki/Direction_finding
>>51978559
I thought this too... as I'm on a main road.
but I've even looked outside and there's nothing going on. it's dead outside at 2am. even the factory across the street is just humming along quietly, no activity until around 4am.
>>51977638
damn, i'm interested. i'd love to be in your shoes anon, that's some serious shit
you can build directional antenna, buy cheap radio interface (RTL2832U usb thingies, $2 per unit), take your laptop and measure signal power in several places, then make map.
>>51978393
that's about 200, maybe 180hz oscillation.
what devices emit frequencies in that range?
>>51978393
somebody check it with a metronome. sync the bassy part with the click on the metronome to get teh exact hz, then we can narrow down what may be causing the device by classification, then by deduction based on OP's surroundings
it could be the navigation of a scheduled flight

i measured 170-171 bpm with fruity loops
This isn't completely related but interesting nontheless:
I had some speakers/sub that every night since I moved the room around picked up weird noises between 10pm and 11pm, changing the volume on external control altered how much weird noise was picked up.
After a few months I was getting pissed and started moving around things more and trying to stop it but made it worse, after catching some weird words I managed to google my way to a website to find out out I was randomly picking up some Romanian radio station that I can't remember now that did some international/english broadcast at this time. I couldn't tune my actual FM radio to find this station though.
I live in the UK, super weird.

it's called DX-ing. It happens because of atmospheric conditions are just right, and allow normal broadcasts to travel extraordinary distances. In CB lingo they call it "shooting skip"
This explains it pretty clearly, in layman's terms.
http://cbradiomagazine.com/Articles/How%20to%20Shoot%20Skip.htm
>>51978818
probably not. it's more than likely a scheduled flight, or some sort of data link with a sputnik, how you call a satellite
>>51978820
You’re cruising down the highway talking to your buddy who is in another vehicle a couple car lengths behind you when all of a sudden you start hearing other CBer’s in the background talking. But what they are saying sounds funny and they are using numbers and phrases you haven’t heard on the radio before. You hear a couple of people mention that they are in states on the other side of the country. How can this be that your $40 Radio Shack CB radio is picking up people talking 1,000 miles away? 10 minutes later they are gone and it’s just you and your buddy on the radio again. What happened?
Welcome to the world of CB skip (also known as DX).
Skip (or DX) is a name we use to describe atmospheric conditions that allow for radio transmissions to travel long distances. These conditions can bounce signals from state to state or even from country to country. While most people have the impression that only Ham Radio operators can talk long distances on the ham frequencies, they couldn’t be more wrong. The CB radio frequency spectrum is located very close to one of the popular Ham Frequencies used for DX and so even CBer’s can enjoy the same sort of amazing distance transmissions.
I won’t go into the technical details of how or why skip occurs as there is already plenty of information on the web regarding solar cycles and causes and effects of atmospheric conditions. What I do want to share with new operators is how to get involved in talking skip and offer some insight and details into the best way to do so.
First of all let’s talk about all those people out there you hear when the skip starts to roll in.
Skip is a big part of the CB radio hobby and there are tens of thousands of operators across the U.S. who enjoy talking long distances when conditions allow them to do so

I install radio transmitters on water meters in houses in my city. It sends out a signal once a day to report usage for billing...no idea of the frequency or anything like that. Maybe you have one Installed?
>>51978840
Fuck off with your cb shit. Literal pleb tier tech. Hell I can throw a wire up n a tree and talk around the world reliably with 5 watts. Cb radio is trash and all cbers should be taken out and shot.
Don't be stupid guys.
It's your power meter sending the usage of the day to your power company. That's why it's at 2am exactly, most people would be sleeping at that time. Let me find the reddit post for it.
It's probably something on a timer like a hot water heater.
We had a weird one locally, it was reliably frequent and drove me mad (it jammed part of the 6.00 newscast on public radio as I was getting ready for work). Turned out to be the local Shortwave transmitter starting up for their 6.30 transmission, they said they had a problem with their daily procedure where the amp would start before the exciter (or something like that) and they shortly after rectified the problem.
>>51978979
Can't find it
See https://en.wikipedia.org/wiki/Smart_meter and https://en.wikipedia.org/wiki/Power-line_communication

I turned the main breaker off, so nothing powered by my house was causing the signal.

Dude, I have 3 frequency counters here, but seeing you are from Seattle and I'm Yuropoor...
The timing is too specific for it to be a old cordless phone, let alone a baby monitor. It could be a harmonic from something in the 30 or 40Mhz range.
Civilian drones also use remote control frequencies in the 27 and 49Mhz range.

Submarines can send radio waves through the earth to contact each other. You're probably picking up talk from submarines or military freq. if you don't have a base nearby, I'd go with the submarines since you live in WA state.
>>51983455
Good thought except there is not enough near-field H-field power to cause sound to emit from non-powered speakers. It either has to be a source in very close proximity or very powerful at a distance. Inverse distance squared and all... Most modern RF receivers are picking up power levels in the pico-to-femto-watt range. Not near enough power.

You will never hear sound coming from NON-powered speakers due to 60Hz power line coupling.

>>51978645
This. Sounds like it could be encrypted.I pick this shit up all the time on shortwave.
As a kid, the land line phone used to pick up the local cuntry and western station until you dialed a number a connected.It would startle me sometimes when the broadcast was speech instead of music.
You could be picking up a harmonic frequency from virtually any wavelength.There's no real way to determine what is creating this short of tracking it to it's source.

What the fuck, that transmission would have to be VERY powerful for that to happen
>>51986188
Yes, you are correct OP. That was my point in fact. All these people assuming it is some distant transmitter are really fucked in the head if they claim to be technology experts.
>>51977638
Not totally related but i used to have a guitar amp that would randomly pick up a mexican radio station signal. My band would be practicing and out of nowhere mexican radio would start blaring out of the amp. It wouldn't happen all the time and it was only noticeable when the guitar wasn't playing so we would just try to ignore it. So during an actual song it wasnt an issue but it was annoying inbetween songs wen we would be trying to talk to each other. The first time it happened we were freaked out cause all of a sudden we heard some guy talking in spanish, first we thought is was some weird secret transmission shit but then a commercial came on and some salsa music and we realize it was just a regular radio station.
>>51986415
Did it happen when your amp was turned off? Cause the OP says it happened when all devices were shut off including speakers.
>>51978616
take a load at this guy
How's your wifi?
No really, do a netsh scan while this shits happening. If it's true radio interference (cb, police scanner, boat radios) then you will have a corresponding drop in wifi strength - anyone who lives close to a radio ham or a boat marina will get shit for wifi. Its one of the few instances where a service provider will run cables around your home or refund your contract without penalty.
Wouldnt help solve it but might narrow down the source/cause.
How about you like ask your neighbours OP?
>>51986515
Sorry anon, but that is complete bullshit right there. Wifi is centered at 2437MHz. All the shit you listed is sub-GHz. Modern 2.4 GHz / 5.8 GHz transceivers will not have a problem filtering all that out. The only way possible for interference from those things would be if they were on top of the transceiver in question. Also, none of those thing would cause noise to be emitted from non-powered speakers in the middle of the night.
>>51987081
I've witnessed it in person and found it with support a number of times. All variants of wifi technology are vulnerable to random radio interference from any thing - it even explicitly states it on the packaging. The extent to which it occurs depends on the strength of the source, the guy who lives beside the boat marina ended up with his internet provider running ethernet through his entire house for him free of charge in order to install enough wifi stations to give him any signal at all - this was a year into his service and a year of sitting less than a foot away from his router just to see a connection!
Cases ive seen in person have not been as severe but one had a radio ham living next door - asked the guy to power down for a minute and suddenly full strength wifi all over the neighborhood because everyone around him had assumed it was shit routers and bought massive repeaters and boosters and god knows what else to compensate. Another was a business with a warehouse. The office in the warehouse couldnt connect to the wifi in the front of the building. Waited till after the taxi place behind them closed for the evening (on a hunch after radio ham guy) and magically the problem went away.
What im saying is, checking wifi doesnt hurt and can help prove whether its a power system or radio source, because radio sources fuck with wifi way more than power. Canary in the coal mine.
Ive never had issues from power systems, large transformers and the like. Sheer mass of metal wont help but general proximity doesnt cause much hassle.
I somehow missed the part about unpowered speakers, that is weird. Be interesting to know what DOES happen at 2am. Ive seen unpowered speakers on long cables pick up weird shit sometimes but usually just the local commercial radio or taxi cab and never anything as loud/unintelligable as that.
Did have one callout where a guy had fitted powerline sockets, and lost his tv signal whenever they were on, that was an odd day.
I used to have this problem and would notice it when I was listening to something and the sound started to dim down.
Basically my computers sound was drowning out the background interference I guess.
>>51987016
this. if it does occur couple of blocks away from your place perhaps try to trace the epicenter of the signal origin. see if it decreases or increases in strength as you move about.
pretty good chance that homeland security box is what is causing the interference. You'd think whatever it is should be in line of site.
Could stand near it at night with a battery operated radio and see if it goes ape shit.
>>51990811
sight rather...ugh
>>51977638
It could be a jammer.
See, for every number station transmitting, there'll be at least one government suspecting it's a message meant for foreign spies within their borders. As such they will do what they can to attempt to disrupt the delivery of this message, for example by transmitting louder at the same frequency and time. They're usually a warbling, sweeping, very disruptive sound meant to match and drown out whatever signal they're trying to hinder. It wouldn't be far fetched to postulate, that it's a US government jammer trying to jam a foreign intelligence transmission.

Anon be sure to keep us updated. Maybe its your aborted brother trying to reach you through radio frequencies.
so it happened again tonight, with ALL electronics turned off, main breaker thrown, cellphone off, anything with a battery unplugged.
I quickly went online to see if any planes were overhead and the only thing I find is this:
https://www.flightradar24.com/LN890WA/8566cf8
which is just a tiny single-engine plane, hardly capable of making insane RF interference
>>51995392
shiiiet OP, it's clearly not a plane. next time leave the house and trace that shit. see if it stops/weakens after any distance. talk to your fucking neighbours about it.
>>51995462
thing is this:
I live in a shitty neighborhood. only neighbors are either non-english speakers (and paranoid) or drug users (and paranoid)
beyond that, the signal fades. I've tried to find it before in my car but it only lasts about 5 minutes.
>>51995485
ok, so next time perhaps take your car and go in to the same direction as you did last time, but double your distance from your house against the furthest point where you last heard the interference. when the time comes, see if you hear it. if you don't, drive towards home. if you do, keep going in the opposite direction. the area affected might be huge.
>>51995540
this is the situation:
2am rolls around, I jump in my car and crank up the radio (usually a lower AM band will pick it up loud and clear)
start driving, and within 2 minutes it starts to fade in any direction I drive. if I turn around, it never gets any stronger.
it's like I'm going insane, except other people can hear it too.

>>51996119
just like flight radar 24, you can track satellites that are going around your location. if it is indeed a satellite causing this interference, it makes sense for it to happen every 24 hours. however given the strength of the signal, its unlikely it's coming a source this far away, and it would probably have to be directly over your head. something to consider.
>>51996173
Where can I check this? Stuffin.space is impossible to use
>>51979153
>https://en.wikipedia.org/wiki/Power-line_communication
To sectionalize the transmission network and protect against failures, a "wave trap" is connected in series with the power (transmission) line. They consist of one or more sections of resonant circuits, which block the high frequency carrier waves (24 kHz to 500 kHz) and let power frequency current (50 Hz – 60 Hz) pass through. Wave traps are used in switchyard of most power stations to prevent carrier from entering the station equipment. Each wave trap has a lightning arrester to protect it from surge voltages.
