Hi Ben. If you unplug the antenna you can tell if the interference is coming from the antenna or power supply . If it's the neighbour's tell them the issue you have and try to get them to turn items off. If it's a pesky power adapter then offer to buy them a new one.. its better to be friends with the neighbour's . Hope you resolve your issue regards pete
This is why I love pmr446 you get no noise it's radio heaven.
There is that
It’s a fm radio hand held. You won’t it isn’t am or ssb. Duh.
Glad I found this channel . I watch your vids on the nitro RCs and Im (subscribed) over there and just added on here too. I am a retired American truck driver and just got the radios back into my life. Bought a new President George FCC SSB radio and got the static floor noise thats how I got here. Sorry I cant offer help, after all I am here to learn, But ya got at least one bud here in the states. 73s
Nice to see you here :)
have you tried to run the radio directly to a battery this will tell you if most of it from the ac or coming in on the antenna direct antenna to radio no swr meter or switches from the antenna might give you an idea where to attack the problem
Yes wonderful your doing CB radio vids again make them every 4 vids that would be fab mate ….
I’ll do my best
I'm having the same symptoms as you are,, and it is frustraring. I took a old transistor hand held walkie talkie around the house. Those old radios will find your EMI. If you have an old transistor radio go walk over to your neighbors lights,, or just probe around outside... you'll hear it! I'm going to start with ferrites on my RG-58U outside coax first.. then work my way inside. Man im glad I found your video before I went broke buying ferrites. You will find it... as I will too! 73's brother. X-Caliber (160) Michigan. 🤘
The ferrites need to be closer to the rig. The PSU should be Linear rather than Switching.
S9 of noise at my house on 11m I have to go up on the hill to use the CB . I feel your pain.
have you looked for the source of the QRM ? often it's the telephone landline or the powersupply of a tablet computer or alike.
Switching power supplies causes static noise specially on AM from what I've heard with other HAMs, those type of power supplies is okey on 2 meters or 70 cm FM, and it's also used for LED lights. The other comment down below maybe right on using tinfoil hat or add more grounding to your station.
Well luckily my PSU seems to be a good one; they can indeed cause issues but mine is alright, I know this because if I run the radio from a battery there is no change. There is also no change if I switch my mains off at the breaker and put the CB on a battery. (That’s how I know the noise isn’t coming from my home) 😉😄
@@RSPYT I have done the same testing in my home. And still have the very same static (EMI) you have. I'm convinced it's my Antron 99 that's picking it up from the neighbors! I'm going to ferrite the hell out of my RG-58U coax outside my house... I hope it works. 73's X-CALIBER (160) Michigan. 👍
usualy its the telephone landine that brings the QRM into the house, in that case its helpful to put snap-on ferrites on the telephone landline where the landline enters the house before the lines distribute the QRM everywhere in the house. it should be at least like between 5 and 10 snap on ferrites on 1 cable. powersupply for internet routers, tablet computers, cellphones and smartphones make QRM too, their lines need snap-on ferrites too. the cable for cable internet or DSL, put on snap on ferrites and look whether the QRM is gone, if not, then that cable was not the source of the QRM, take the ferrites and try on the next cable. a handheld cb radio can be a help to pile up the QRM source, if the QRM gets very strong, remove the antenna and try further. in this day and age there is usualy multiple QRM sources as there are alot more electronic devices, that needs a more attention to recognize a change in the QRM in the cb-radio when there are a snap-on ferrites attached on a cable, to then go and look for more QRM sources.
Great video! How frustrating man. I get loads of random QRM round my way in Surrey. I haven't got a homebase setup as I haven't got the room, or the correct building, but driving round mobile, it is amazing how many hotspots of utter crap you can drive through. Sometimes it takes a couple of blocks worth of houses and roads before it starts to fade away... 😒 I hope you get to the absolute source of the issue 💯 %
Maybe ask your neighbours if they could kindly turn the lights off at the breaker as an experiment? But, if you do find it is their lights, I'm not sure what you would do about it! 😆🙈 Good luck man 🍻
Great video Ben. Very interesting too. Hugely amusing.. Loved it.🎧
Cb radio only thing allowed under off com rules and police for using while driving. Are you on frequency modulation or am? CB IS THE FUTURE. No network bills, twin ant tx, pole, linear amp to get you pretty much around the world, and a lot of burn outs. CB IS BACK!
Your neighbors are growing weed. Those lights they use will do that, they have very bad bleed off. Do what I did, I asked them to use better lights or shield the ones they use. If they wont even help. Call the electric company and tell them as soon as your neighbors electric was turned on you can hear jack out of your radio. They will know what to do.😎
I thinks exactly the same Mysterious Outdoors 👍👍👍
Keep in mind...it is seed season...The RF on radio's are gonna be harsh....lol
So many people start indoors....
Your Lincoln and the President HR2510 are the same. There are three issues with these older radios: Electrolytic capacitors dry up (the usual symptom is slow boot of the screen), the brown "Sony Bond" glue eats away at the components leads and pc board traces and the screen LCD screen starts to darken. You did state the noise started with new neighbors, but, you may want to have the radio checked out. Cheers.
That radio has just come back from the rig doctors after I asked him to see why it was picking up extra noise. He concluded it was fine.
@@RSPYT
Cool.
If you still get interference when hooking the radio straight to a battery I would try multiple rings on the coax because your power cords look like they have plenty.
agree.. I have the same static he's having. I'm glad I found his video before I went broke buying ferrites! I'm going to start with my coax outside and work my wat in!
Could'a, Should'a, Would 'a !
The first thing you should have done, is to turn off the electrical power to each circuit, one at a time in your own home !
Obviously to see if the noise is being generated in your own home !
As many modern appliances generate electrical noises !
Especially items from China !
Television sets, Touch Lamps, Wall warts, Switching Power supplies, Keurig coffee makers, etc. !
Are all known to make horrible amounts of noise !
Some, like switching power supplies may even move around frequency to frequency !
If you're lucky enough to find the noise in your own home, you simply begin by unplugging things until you find the item, or items generating the noise !
This all may sound simplistic, but the shot gun approach you're using in this video, I doubt will yield much in the way of success !
Hope someone finds this helpful ?
Looking for noise outside your home, is a whole other matter !
👍😉
I feel your pain m8,every night at around 9pm,my noise goes from s2 -+10 but worse band is 20m by far!!! Sure its tacky cheap garden lights but so many houses around me have them.My beam helps loads but typical when I beam to usa thats where the worst noise is....Good luck getting yours sorted
It used to be the other way around us cb people used to knock out peoples television receptions lol
Haha I know man funny shit
You have my 100% sympathy, My both next door neighbor's have solar panels which produces 9Db noise, I will turn my car into a mini camper & move my shack into that, problem solved, Happy Day's 🤣😂😂😂
ofcom
Put your radio straight to a car battery then switch the power off to your house in the main fuse box. Turn it all off and wait a couple of minuets because some capacitors hold charge even when switched off so wait a couple mins then check your radio. If you still have interference then it's coming down your antenna in which case get a good earth onto your antenna if you haven't already. Try that buddy.
Did you watch my video on how to find and get rid of interference and repeat it to me lol.
Hi Ben, just watched your video. I do not know if you are still on air and if you have solved your interference problem.
As a tip, I would start to search where this interference is coming from. You have two possibilities; from your power supply or from your antenna.
To find out which one is the source of your problem, it is a simple step. Switch on your radio and remove the antenna connector. Should the signal meter go practically to 0, you have an interference coming from the antenna. If the signal remain strong, may drop down slightly, it is a power supply problem.
Now-a-days the interference from LED lighting is getting worse with the cheap chinese products on the market. They emit strong wide banded signals that disturbs two way communication systems. These signals are picked up over the antenna and to go to a neighbour and asking him to switch off his light, is not a light way to go. To filter these signals is an expensive measure and no garantee that it works in giving you your full reception back. Such filters can cause the reception sensitivity to drop so that only strong signals are available.
Looking forward to gettting a reply,
Hi, the problem is next door, they have loads and LOADS of LED lights. I’ve since given up with radio.
@@RSPYT oh man, how sad. It is terrible that such interference causes one to give up his hobby. I have also problems with interference in my homebase, so I solved the problem by going mobile and making my contacts.
I get alot off interface so I went out and got the new crt ss 6900v nrc and my noise levels have dropped to a 6 in a day 7 at night cos of street lights behind me so I put the nrc on and it makes a difference
Google Common mode chokes.
Hey Ben. I used to get terrible interference on 10m and it would start at 3pm every day and I was stumped until the next door neighbour sadly died. . . . No more QRM. . .
You could try an earth rod which might help but it certainly won't make it worse. 73's.
Hello mate, I have 2 earth rods ☹️
Have you placed another radio in place of yours? See if the problem is indeed external. There are diodes that regulate receive sensitivity, if one has broken down it would do what you are describing.
maybe try a different radio...
ask Alan in Hockley, as he knows lots about radio etc.
I only go on PMR now and then when I go walking around Langdon hills.
Try running it from a car battery to eliminate the mains.
I've also got noisy neighbours rusty they live about and below me and each side..in fact my whole apartment block in alicante is full of Spanish people ..crazy foreigners.... cant you just turn up the volume mate. -:)
Have you tried turning it off and on again...
No seriously, you obviously have a problem there. If it were me I would go about it methodically like someone else suggested. I'd probably start by taking all the ferrites off.
QRM Eliminator X-Phase
uses a co phasing antenna worked for me £58 ebay.
Ferrite is bad to use on coax cable. It will get hot when power goes through it.
Who ever told you that is a plonker.
Keeping cabling as short as possible does help, so does a decent method of earthing your station.
Unnecessarily long power leads are very good at picking up interference.
Sorry to say this - your setup is a mess.
If you change your mode to either lsb or usb doesn't the noise level drop? My radio gets a huge noise level on AM but on SSB not so much
i have same problem all over HF, CB and on 2m i just cannot use any radios most days now. Mansfield.
Mate I have the same thing going on , it’s just the time we live in unfortunately, the band is hugely effected thease days ,
Yeah very sad man!
whe have this all year in here,and not just me everyone that i know has this s9 qrm thats why i m always on 27.985 close to 10 meters lol
Will these ferrite rings stop stray RF
Hi Ben have tired put and ground spike in and earth all your radio gear to the ground. I had terrible noise from the school behind me. By putting in a ground spike and running earth's to all my equipment, it cut my noise levels by 60%. Hope it helps. 73s
Hi Ben. How about trying to disconnect all and use only one radio just to see if that gets any better. If it gets better than the problem might be in your shed. I'd do it like that first. Then start organizing your cables, they all touching, all on top of eachother. I know, that shouldn't be a problem but you never know. A noice filter could do, but if it really is the neighbs then that wouldn't do any good either. The other option is an RPG louncher. You can always put the blame on Russia, at this point anybody would believe you for sure 😂🤣Anyways Ben i hope you get it sorted, it's annoying i know. Keep em comming. 73- sector 5
Well as I’ve mentioned in the past (but not in this video because I simply forgot) I know the noise isn’t anything to do with my shed or home because I’ve switched the mains off at the RCD box and run the CB on a battery with no change. Interestingly though my mate
Down the road has recently has his noise come up to the same level also, maybe it’s not my neighbours and it’s something else in the area… who knows….
you could try a tinfoil hat ! :o)
Good idea!
Lol
Turn off all the fluorescent lights
Why is your hood up indoors ?
Well, can’t I have my hood up while indoors?🧐
@@RSPYT was it cold ?
@@RSPYT going to try some of them for my noise. Thanks.
@@ratcliffave Most probably this video was ages ago so I can’t remember lol.
Need to take the power supply off the cb. Grounding issues
You put ferrites on the source of the noise not the receiving end. So they need ferrites not you. You’re wasting time doing all that. I’ll stop watching because I know the outcome. Noise will be there.
You may of stopped watching but you left 3 comments, thank you for those.
This was years ago I can’t remember what happened but there is no noise now so something worked/changed.
Love this! Move the plant out the way. TOWIE. The only way is Essex! How to legally tx under off com rules... Fantastic.
