Some examples of using an AM radio to detect EMI in everyday objects to determine power management and data rates. I have a second channel: / @markfurneaux2659
OK so like, I am a totally blind person and when I was a kid and didn't have speech enabled electronics, this is the method I used in order to detect whether a device was on or had the correct setting. This was especially helpful with things that had menus where you had to scroll around and press either OK or cancel. A perfect example of this had to be those MP3 players that were around in like 2008 where all you had was a little joystick thing up top to scroll up and down through the menus. The music listening mode and voice Recording mode were in completely different folders on the device so I had to be near a radio if I wanted to switch between them. I would just tune to the lowest frequency on the am band, hold the device up to the radio and get familiar with what sound corresponded with what element or command over time.
Have You Read The Braille Bible or Listened to Audio Bible? I am going to Pray Your Vision is Restored in Jesus Christ's Name, just as he spit on the ground and rub dirt into a blind man's eyes and healed him of blindness. I Love You and May God Bless You
Sometimes I tune my truck radio to a blank spot on the AM band, and drive around listening to all the different kinds of RF interference. It's amazing how strong some of it is.
Love this article and I want MORE! As a youngster my passion as an electronic enthusiast dates back to the 1960's wow... Early on as a child, this field of dreams or technological passion could only be quenched with a ride to the town dump or landfill. Unfortunately... my parents weren't very keen on me removing the innards of old TV/Radio consoles to be transported home. My folks didn't recognize them as treasure's as I did. I'm not sure why.... If I could only find an old palm size AM/FM radio now.....!?!
I use AM Channel 520 which seems to be the loudest for 60 hz.. when a florescent bulb is going bad, or a switching power supply, they work great to detect. thumbs up.
I have been using am radio for interesting content and to listen for lighting strikes while on white noise. It also will pick up electric current so could find hidden surveillance by detecting current.
I do not have tv anymore. AM AND SHORTWAVE RADIO are my thing! I love late night am and shortwave. So much more truth and info that tv has not!! I would rather have my multiband radios, than any television!
People can be identified by which phone they have in their pocket and possibly if hidden software (malware) is active in the background. Even data can be extracted from IT equipment, which is known as TEMPEST technology. The continuous tone you hear from devices is often the keyboard matrix or VFD display driver signal. Try to tune the radio to other frequencies (outside active broadcast). Many devices do strange overtones, which can be also used in electronic music. E.g. my Sharp talking clocks and calculators do plenty of crazy additional tones and distortions from data processing thos can be heard on AM frequencies. Also a faulty quartz or if a chip is crashed or still computing something can be heard this way.
As an amateur radio operator I can tell you that the Ethernet over power line devices create horrendous amounts of noise! If you live next door to someone with these devices (or even two to three houses down) it renders your HF equipment un-usable
Andrew Dickson I live next door to a guy with radio station, it's on the roof, his equipment goes from the 4 antennas that are 15 feet high, 2 pointing up and two other poles horizontal suspended off the ground 3 feet, he has a shed with equipment and wires from shed going into the bedroom window that is right beside my bedroom, we share the wall. I feel sick and tired if I stay in the room too long, EMF detector shows 2-8 milli gauss on my bed at times and my heart skips a few beats more than normal when I lay on the bed or near the bed. Recently there is a high pitch beeping noise coming from his equipment, I knocked on his door to ask him if he can hear it and he got angry right away and said its not from his radio and would t even let me finish my sentence. This was the second time in 1.5 years I spoke to him and first time mentioning his radio station. He came to my door 5 mins later banging loudly and said the beeping is not from his radio station and nobody can come in and check it and if I want to check it then give him $20, this is a grown Russian man in his 60-70's and I asked politely if he can hear a beeping noise upstairs and he goes off the deep end and comes down to my door to continue his rantings. I can't connect to wifi 9/10ths the time in this room because of his radio station and if I walk -0 feet away from bedroom the signal is fine. So can you help me out to not get exposed to EMF and my health and be ab,e to use my wifi or do I have to report the guy, I don't want to because of his words and actions he is acting really angry and guilty and over a beeping noise, maybe he's a Russian spy with a lot to loose, haha, but seriously I need help with this so what would you suggest? Peace and Blessings
@@crying_hippy Hopefully by now you've discovered a USA government agency known as the Federal Communications Commission (FCC.Gov), have filed a complaint, and the situation is resolved - OR- you moved out -OR- you've documented your ailments via doctors and have sued the offender.
@@usernamemykel I had to move as it was causing heart palpitations and I'm high risk stroke patient. He and the neighbour beside him both used chemicals on me too, like gasses, ammonia, lead, arsenic, paint thinners, etc. The cops didn't care even said I'm probably right about the paints and said to file with landlord tenant board, I called fire department, they couldn't detect anything first time but did the second time and said it was fumes from sewer, but it wasn't it was some type of gas the guy was using to come inside my bedroom window. I'm in Toronto Canada where they let people get away with murder, literally. I told friends and family this man will probably end up poisoning his dogs or himself with all this crap he's using on me. Less than 2 months after moving he died of heart issues, he went to russia his country to seek help as canada couldn't help him and he died in russia. May God Have Mercy On His Soul Thanks, Much Love and God Bless You
Super glad to hear that the correct unit of measurement - the "shit-ton" - being used judiciously. I keep an old AM/FM radio for just this reason and use it to compare new product designs.
I remember having a reference book when I was a kid in the '70's that used to refer to nuclear weapons as having a yield the equivalent of how - ever - many thousand _'short_ - tons' of TNT. For all these years I've wondered what a 'short - ton' was, and turns out all along it was just some kind of a misprint! ; ^ )
My EDC radio is a FM/AM/WB La Crosse Weather Band radio (815-805). Glad to hear another use for an AM radio. And a radio is a great way to gather intel for many reasons (power outages, bad weather on the way). Thank you for the video ! tjl
When I was much younger, I would always use an AM radio to listen to the sounds that different devices made. My favorite sound was from a GameBoy Advance, which would sound like a nuclear reactor upon turning on :D
Over the holidays I was listening to AM radio in my pickup. I pulled into my driveway and at a very specific point a signal from something blanked out a very strong AM radio station. I could move 5' east or west and the station would come in. I have a little AM/FM/SW radio, not too unlike the Grundig in your video. I used it to attempt to track the source and I couldn't. The frequency was 738.738 kHz. I initially thought it was power companies meter but walking toward the meter resulted in loss of signal. In fact, I almost called them to chew them out lol I can see a very small peak in at the frequency I tuned on the AM radio, on my spectrum analyzer. It's about 15' away in the house. The peak is very small but it's there.
When I was a kid in the 80's, I found interesting sounds by using one of those Radio Shack suction cup inductive telephone recorder things. Either plugged into a little Radio Shack amplifier speaker, or into a tape recorder.
used this to find out why my internet was so bad. amazon alexas wall power adaptor was kicking out sooooo much, removed it and the noise in the internet main line into house was fixed.
When you put a watch to a radio you can hear it flickering to different time change and when you put a radio to TV it will make a noise and you can see or hear when the pictures change won’t be able to see it but you’ll be able to hear the pictures change to different sounds When you record lightning strikes on radio with an audio recording it is pretty interesting you put one radio at one end of the deal and the other radio at the opposite end of the deal therefore you get lightning in stereo and you can get one radio getting lightning it from the interior of British Columbia and the other radio picking up lightning to the east to the Fraser Canyon Ave., British Columbia Fraser Canyon is really cool
That i so very cool. To be able to hear the ELF EMI. But what happens when you use shielded Twisted pair in your Ethernet cabling would you still EMI. You shouldn't because by its very nature the line is supposed to protect against it.
I bought a multimeter to see how much my body was picking up. Got an emf meter that works sort of like this, now looking at the dirty electricity meter, then found an oscilliscope. I'm building a house and trying to make it as healthy as possible. I am sure I don't eat all this stuff. It's probably redundant. And most of it I don't even know how to use it lol Great video though! Digging through my garage to see if we have one thought we did
+Mark Furneaux... I am lost, what was the reason of the video? just to hear the different noises?? or are you doing a video to help emilimate problems???
Haha since many of us do not have am radios that's a problem. Thought you should know your exact models price is trending on eBay. I scored one for 18 now I see them for 30 and a couple on bid. Something something curiosity and cats maybe. Way to go Mark ;)
This is very cool and useful. I like radio anyways, free, and travels ma y hundreds of miles under nighttime ionosphere changes. A weaker ionosphere at night actually helps AM go further because of the wavelength of AM. Could seem to be the other way around, but it isn't.
It would be interesting to see the difference in emi noise when a 1 gig link is just active and when it is fully saturated and when ir is in between, this way you can tell how much traffic someone is using jst by scanning their cable...
Interesting I have a Meterk gauss meter for detecting EMF & EF. Are those cables Cat 6 and fully shielded? I run cat 6 full shielded ethernet cables from my router to two computers and two printer into the router, the routers Wifi signal is very strong and Very UN healthy so I turn off the Wifi, and run direct into router via ethernet and then to cable modem. That way you are Not getting Blasted by Wifi toxins. I turn on wifi only at times when I Must have it on. Wifi is like having a cell tower in your house
I will do a review of it later. It is fine for the price, but you get what you pay for. It is usable, but don't expect the same features as a mainstream phone.
Interesting vid. Thank you. I use a multi-frequency metal detector and EMI sometimes interferes with the signal from the coil (round part at the bottom of the shaft). I’d like to find and understand the EMI source. Would the frequency tone get louder as I get closer to the source? How can I replicate the EMI that interferes with my detector? I know there are FCC regulations to help prevent EMI interference, but I think it would be okay if I’m doing it to my own equipment. In advance, thanks for your advice.
I have the same radio but it's blue. Yours is in better shape than mine it's in rough shape but it still works. the antenna on mine broke off so I have a car phone antenna on it. The power button no longer works so I modded a regular switch into the circuit so you can just flip it on or off. I have this old craig android tablet and it was a piece of junk and would freeze a lot. I would use this method to tell if it was actually doing anything.
I use it to help clean my house from EMI. Some people are sensitive/allergic to EMI and other frequencies. Also, some radio's are much better than other, i tested a couple. There are big differences. Some have noise filters that make the radio less sensitive to EMI.
What about RF? Have you been able to pick up RF as well using this, and if so, are you able to tell how much RF is being emitted by a device/in an area?
@@Chris-dw6cu I'm using a budget RF meter (Cornet ED88T) for RF in the GHz range and a Esmog Spion (=expensive). Links to websites where you can buy these and all kinds of other good meters are on my handy EMF webpage. It's best to check those links out because randomly looking on the internet you can find all kinds of crap recommends.
@@Merializer thanks for the tips! sounds like for accurate RF detection you gotta spend the big bucks - no way around it. I think RF detection is more important than EMI given what's going on in the world today.
@@Chris-dw6cu RF, EMF and EMI are used almost synonym. In marketing terms they rarely make a difference, although EMF would also include DC or low frequency components of electric and magnetic fields.
STP cables are more to prevent noise from getting in rather than out, but it would reduce the emissions drastically. It won't block them completely though.
I know this was uploaded a while ago, but how viable is this for surveillance? Like, is it possible to make a guess about the kind of data being transferred through Ethernet JUST by listening the EMI that it produces?
can someone tell me why something that isn't plugged in would cause AM interference? Were trying to locate source of high frequency noise (spectroid app didn't find anything). Turned off all electricity to home; discovered fireplace, thermostats and old printer interfere with AM radio static. Thanks
should i get a rf meter or a am radio.i having issue with my pc.we have cell radio tower in our apartment on the roof .pls help me do you think it's a rf issue i am having
I’ve got a turtle beach headset and when I’m on Xbox I put my phone on the cord where the vol and mic controls are and turn on my cell data, it’s enough noise that other people in a party can hear it
I think the lightning storms and I am radios it’s pretty cool and I could use a Watch on an M radio to know when the watch is blinking because I am totally blind I like to be able to tell you that if you if you were in my radio to the TV it’s going to blink different pictures you’ll know when the pictures change because of the different sounds When you turn the radio to a TV and watch the pictures flash into different pictures it makes different noises it’s quite interesting
Oh so you do use kdenlive, thats great! I have one other question that is incredibly embarrassing... I am a new grad electrical engineer, when I watch videos like yours I honestly feel like I don't deserve my degree and that I might fail my new employer, I desperately want to learn more and become a useful member of my new engineering team. How do you continue your education? You always impress me with how well you understand things and I aspire to become someone like yourself.
I'm a guitar player and I'm getting tons of noise whether I'm playing through a modeler, interface, or regular amplifier. I've checked the shielding in my main guitar for continuity and it's fine. I've unplugged a bunch of stuff and plugged it all back in. No difference. To get rid of fan noise I actually moved my computer tower to an adjacent room, and I was hoping it might solve the EMI thing, too, but no luck. I don't hear any regular clicking or anything. It's a hum but it doesn't sound like 60 cycle hum, and I don't think it's a ground loop. Humbucking pickups are much quieter but I can hear it if I crank the amp. Strangely, if I turn my chair it does go away or at least decreases a lot. If I'm facing my computer monitors/keyboard/usb hub/etc it's noisy, but it remains noisy even if I cut power. It must be coming from outside the house. The main power line comes in underground on the other side of the house. The air conditioner compressor is outside the window but the noise doesn't change when it cycles on and off. I'm going to try this thing with a radio (if I can find one), but am not terribly optimistic. I've been trying to figure this out off and on for three years now. If anyone has any ideas I'd be grateful to hear them.
@@vul5925 I can't find anything using the radio. It's really easier to just pick the guitar up and move it around, but the noise seems to be coming from a wall with no electricity in it. It's a mystery. As it happens my favorite guitar just has noisy pickups. I've changed the pickups and have found quieter ones but they don't sound as good so who knows.
@@saddestchord7622 Have you seen SamuraiGuitarist's video ("solving another mysterious house noise")? There it was coming from a transformer outside the house.
@@vul5925 We don't have any transformers really close by like that guy did. Maybe about 300 feet away on a pole there is one. It may be coming from the gas meter. The radio isn't nearly as sensitive as a guitar, so I need to find some battery amp to take out there.
Great, now how do we mitigate the source. So many things making noise. Now how does that get to the antennas? If I go outside there is nothing registering, well except the dam solar. We are going to be having a discussion with the company.
I've noticed that bringing my AM radio up close to my phone and tuning it to 800 KHz *while* the phone is playing any sort of audio causes the radio to pretty much work as a wireless speaker. This stays true even after I turned on airplane mode. I wonder how that works?
it's pretty much what it says on the tin lol although it might not work with every phone/radio, tried it with both my shitty galaxy A01 knockoff and my better xperia xzs and it works (tuning doesn't matter, 800 KHz on my pocket radio happens to give the "clearest" sound although it's still covered in static)
Wow using radio to search for interference is just like in the game Silent Hill where before the undead can seen you'll hear increase static in the radio.
...whatever, you're a square wave. haha, JK man...this was an excellent video. I use this trick for all sorts of stuff... Was good to finally learn the science behind it though, thanks for the info/video and best of luck to you on all your endeavors.
I accidentally discovered this in my car by resting my old iphone next to my center console. i found out that after a forced update, apple basically bricked my old iphone 5 by forcing it to send a crazy amount of extra power to the mobile phone antenna all the time, therefore draining my phones battery with only about 4-5 hours of screen off time. after discovering this and with 3g towers getting phased out, i got one of those 4g modems and moved over my sim card, and unplugged the wire leading to the cell phone antenna inside. now my phone gets several days worth of battery life... i wouldnt have noticed this if i didnt realize before the buzz on my cars radio only happened when i was sending messages/using the internet on my phone, but after the update it was just constantly blasting out a signal for no reason. im sure apple has no idea what im talking about and i just need to buy a new phone that correctly loads internet ads and sells my data/browsing habbits
human microchip--they don't need to microchip us with or without our consent, it's called a smartphone...and soon 5G which is the ultimate information gathering system on all humans within range. but to detect a microchip you may need to turn the volume to max on a really clear radio station to hear for any differences when moving radio over body
@@joelschmierer3544 There are no microchips hidden in vaccines or whatever. Such technology does not exist. Nowadays RFID chips (ask your vet) are glass capsules of at least several millimeter size.
But a radio is at least as good as primitive EMF/bug detectors (few blinking LEDs + beep) and in some ways better, because you hear the structure of the signal, which helps to estimate what it is.
Bro, please get to the point in your conversation in your video . After the first 1 minute and 44 seconds, you didn’t get to the main point. I lost patience, and skipped on to another video.
OK so like, I am a totally blind person and when I was a kid and didn't have speech enabled electronics, this is the method I used in order to detect whether a device was on or had the correct setting. This was especially helpful with things that had menus where you had to scroll around and press either OK or cancel. A perfect example of this had to be those MP3 players that were around in like 2008 where all you had was a little joystick thing up top to scroll up and down through the menus.

That way you are Not getting Blasted by Wifi toxins. I turn on wifi only at times when I Must have it on. Wifi is like having a cell tower in your house
So AM Radio Can Easily Convert Electromagnetic Waves In To Sound Waves Without Modification ?
Great video. Also how do you like your doogee x5s? Is a cheap chinese smartphones worth it compared to a moto g etc?
I will do a review of it later. It is fine for the price, but you get what you pay for. It is usable, but don't expect the same features as a mainstream phone.
Interesting vid. Thank you.
I use a multi-frequency metal detector and EMI sometimes interferes with the signal from the coil (round part at the bottom of the shaft). I’d like to find and understand the EMI source.
Would the frequency tone get louder as I get closer to the source?
How can I replicate the EMI that interferes with my detector? I know there are FCC regulations to help prevent EMI interference, but I think it would be okay if I’m doing it to my own equipment.
In advance, thanks for your advice.
I have the same radio but it's blue. Yours is in better shape than mine it's in rough shape but it still works. the antenna on mine broke off so I have a car phone antenna on it. The power button no longer works so I modded a regular switch into the circuit so you can just flip it on or off.
I have this old craig android tablet and it was a piece of junk and would freeze a lot. I would use this method to tell if it was actually doing anything.
STARTS AT 5:40
I use it to help clean my house from EMI. Some people are sensitive/allergic to EMI and other frequencies. Also, some radio's are much better than other, i tested a couple. There are big differences. Some have noise filters that make the radio less sensitive to EMI.
What about RF? Have you been able to pick up RF as well using this, and if so, are you able to tell how much RF is being emitted by a device/in an area?
@@Chris-dw6cu I'm using a budget RF meter (Cornet ED88T) for RF in the GHz range and a Esmog Spion (=expensive). Links to websites where you can buy these and all kinds of other good meters are on my handy EMF webpage. It's best to check those links out because randomly looking on the internet you can find all kinds of crap recommends.
@@Merializer thanks for the tips! sounds like for accurate RF detection you gotta spend the big bucks - no way around it. I think RF detection is more important than EMI given what's going on in the world today.
@@Chris-dw6cu about RF versus EMI: still not sure what is the biggest problem and I know a lot, it's not simple.
@@Chris-dw6cu RF, EMF and EMI are used almost synonym. In marketing terms they rarely make a difference, although EMF would also include DC or low frequency components of electric and magnetic fields.
I assume that a shielded network cable would produce less signal leakage or would it even block all of it?
STP cables are more to prevent noise from getting in rather than out, but it would reduce the emissions drastically. It won't block them completely though.
How can i turn a fm sw fw lw radio to a am
I mean im not very good but does at least sw fw or lw work
I know this was uploaded a while ago, but how viable is this for surveillance?
Like, is it possible to make a guess about the kind of data being transferred through Ethernet JUST by listening the EMI that it produces?
No
@@maxthewincat CIA shill. Your outdated info is unclassified by noe
Yes. However, you need and SDR with a decoder.
can someone tell me why something that isn't plugged in would cause AM interference? Were trying to locate source of high frequency noise (spectroid app didn't find anything). Turned off all electricity to home; discovered fireplace, thermostats and old printer interfere with AM radio static. Thanks
Can this also be used to detect RF or only EMI? Devices to detect RF are much more expensive.
should i get a rf meter or a am radio.i having issue with my pc.we have cell radio tower in our apartment on the roof .pls help me do you think it's a rf issue i am having
I’ve got a turtle beach headset and when I’m on Xbox I put my phone on the cord where the vol and mic controls are and turn on my cell data, it’s enough noise that other people in a party can hear it
Or for checking noise levels on telephone pairs. Opentherm signals are noisy too!
I think the lightning storms and I am radios it’s pretty cool and I could use a Watch on an M radio to know when the watch is blinking because I am totally blind I like to be able to tell you that if you if you were in my radio to the TV it’s going to blink different pictures you’ll know when the pictures change because of the different sounds
When you turn the radio to a TV and watch the pictures flash into different pictures it makes different noises it’s quite interesting
Mark, how do you merge your audio recorder's recording with your cameras to create a video that doesnt seem out of sync?
Kdenlive has an audio sync feature. All I do is snap my fingers at the beginning of each take and it can sync based on that.
Oh so you do use kdenlive, thats great! I have one other question that is incredibly embarrassing... I am a new grad electrical engineer, when I watch videos like yours I honestly feel like I don't deserve my degree and that I might fail my new employer, I desperately want to learn more and become a useful member of my new engineering team. How do you continue your education? You always impress me with how well you understand things and I aspire to become someone like yourself.
I didn't answer this because I might do a video on this topic in the near future.
Oh that would be incredible, thank you so much for your consideration!
Do you think that HIGH EMI could effect small DC motors?
Yes
So AM band covers 540 - 1700kHz. How can you scan higher in frequency using AM ?
Computer mouse produces different noise when you are moving it. To hear 2.4 and 5 GHz you need to put receiver algined with antenna
I have a magnavox ae 6690. its a kick ass little radio and am sound good on it! (sensitive too!)
So yeah, don’t underestimate am
Very cool
Does it pick up Pulse Radio Frequency ??
I have digital calipers and when i put them close to my cfl work light the display goes haywire.
I'm a guitar player and I'm getting tons of noise whether I'm playing through a modeler, interface, or regular amplifier. I've checked the shielding in my main guitar for continuity and it's fine. I've unplugged a bunch of stuff and plugged it all back in. No difference. To get rid of fan noise I actually moved my computer tower to an adjacent room, and I was hoping it might solve the EMI thing, too, but no luck.
I don't hear any regular clicking or anything. It's a hum but it doesn't sound like 60 cycle hum, and I don't think it's a ground loop. Humbucking pickups are much quieter but I can hear it if I crank the amp.
Strangely, if I turn my chair it does go away or at least decreases a lot. If I'm facing my computer monitors/keyboard/usb hub/etc it's noisy, but it remains noisy even if I cut power. It must be coming from outside the house. The main power line comes in underground on the other side of the house. The air conditioner compressor is outside the window but the noise doesn't change when it cycles on and off.
I'm going to try this thing with a radio (if I can find one), but am not terribly optimistic. I've been trying to figure this out off and on for three years now. If anyone has any ideas I'd be grateful to hear them.
How'd it go?
@@vul5925 I can't find anything using the radio. It's really easier to just pick the guitar up and move it around, but the noise seems to be coming from a wall with no electricity in it. It's a mystery. As it happens my favorite guitar just has noisy pickups. I've changed the pickups and have found quieter ones but they don't sound as good so who knows.
@@saddestchord7622 Have you seen SamuraiGuitarist's video ("solving another mysterious house noise")? There it was coming from a transformer outside the house.
@@vul5925 We don't have any transformers really close by like that guy did. Maybe about 300 feet away on a pole there is one. It may be coming from the gas meter. The radio isn't nearly as sensitive as a guitar, so I need to find some battery amp to take out there.
I have the exactly same problem
so..you could theoretically sniff data from an ethernet cable or whatever with an AM radio ?
No. The frequency is much too high for an AM radio.
What is its name and where can I buy it please
Great, now how do we mitigate the source. So many things making noise. Now how does that get to the antennas? If I go outside there is nothing registering, well except the dam solar. We are going to be having a discussion with the company.
I've noticed that bringing my AM radio up close to my phone and tuning it to 800 KHz *while* the phone is playing any sort of audio causes the radio to pretty much work as a wireless speaker. This stays true even after I turned on airplane mode. I wonder how that works?
woah what? could you elaborate on how to do this? this would seem like a cool party trick to try out for my below average intelligence friends
it's pretty much what it says on the tin lol
although it might not work with every phone/radio, tried it with both my shitty galaxy A01 knockoff and my better xperia xzs and it works (tuning doesn't matter, 800 KHz on my pocket radio happens to give the "clearest" sound although it's still covered in static)
Wow using radio to search for interference is just like in the game Silent Hill where before the undead can seen you'll hear increase static in the radio.
...whatever, you're a square wave.
haha, JK man...this was an excellent video. I use this trick for all sorts of stuff... Was good to finally learn the science behind it though, thanks for the info/video and best of luck to you on all your endeavors.
I tried it and my router was ringing! No idea what that was about.
I accidentally discovered this in my car by resting my old iphone next to my center console. i found out that after a forced update, apple basically bricked my old iphone 5 by forcing it to send a crazy amount of extra power to the mobile phone antenna all the time, therefore draining my phones battery with only about 4-5 hours of screen off time. after discovering this and with 3g towers getting phased out, i got one of those 4g modems and moved over my sim card, and unplugged the wire leading to the cell phone antenna inside. now my phone gets several days worth of battery life... i wouldnt have noticed this if i didnt realize before the buzz on my cars radio only happened when i was sending messages/using the internet on my phone, but after the update it was just constantly blasting out a signal for no reason. im sure apple has no idea what im talking about and i just need to buy a new phone that correctly loads internet ads and sells my data/browsing habbits
Is like a ghost box
am detects lightening as well
so you can search for bugs with this :) cool
Is it just me or does the video cut around 8:00
+BenNextPlays okay
cool
Wow
I tried this on my computer and its really noisy.
1Shingo5 cool
Can you detect human microchip with it?
human microchip--they don't need to microchip us with or without our consent, it's called a smartphone...and soon 5G which is the ultimate information gathering system on all humans within range. but to detect a microchip you may need to turn the volume to max on a really clear radio station to hear for any differences when moving radio over body
If its real you should be able to. Your body alone may provide mild results tho. Do not worry comrade, we are not surveilling you
@@joelschmierer3544 There are no microchips hidden in vaccines or whatever. Such technology does not exist. Nowadays RFID chips (ask your vet) are glass capsules of at least several millimeter size.
When I play my electric guitar it picks of these frequencies from my phone.
Try it next to a computer mouse..and move the mouse
It's pronounced "Groon-dig" I think
AM radio method is cheap but does not show anyone severity of signals the way 100-200$ meter/detectors do
That's what I was wondering about. How about RF? Can the AM radio also give you info about RF emissions?
But a radio is at least as good as primitive EMF/bug detectors (few blinking LEDs + beep) and in some ways better, because you hear the structure of the signal, which helps to estimate what it is.
I discovered this on accident with the sounds when I put the radio next to my laptop now I know why
I want to detect where Sepho is I lost him he was a spirit roaming around my house
creepy
Put me to sleep dude
12 minutes to say an am raido can pick up e.m.i
Bro, please get to the point in your conversation in your video . After the first 1 minute and 44 seconds, you didn’t get to the main point. I lost patience, and skipped on to another video.
