G4NSJ - Noise on 60 metre band 5MHz amateur ham radio
Вставка

- G4NSJ - Noise covering the HF spectrum is worsening. Sadly, the noise on 60 metres, the 5MHz frequencies, is particularly bad at my QTH. I've made this video so you can not only hear the noise but see it on the waterfall display.
www.g4nsj.co.uk/ - Наука та технологія
The sources of noise on HF bands could be one or more of the following:
1- Solar power systems in the neighborhood ( chargers and inverters)
2- LED street lights
3- Power line transformers
4- Switching mode power electronics everywhere, including poor phone chargers.
5- Over the horizon radars.
Interesting points, thanks. Cheers, Ray.
I was out on my 2nd ever ARRL Field Day last weekend and "wisely" brought a solar panel, lead-acid battery, laptop and 400W inverter to keep the laptop topped-up. That last thing was not so wise. The little inverter did lay a local blanket of noise on our affairs, so I ditched it quickly. A head thumping moment as I should have known better.
We live and learn! 👍
The led street light right out front of my house. It messes with 60meter band. It wasn't till they I stalled that light I started having all types of troubles. It's bad enough that the power lines or in bad shape around me,now the led street light is bad on noise.
I've had to go around my house and check and switch out so many power supplies,and light bulbs even?? It's just crazy now of days,I'm pulling my hair out. I'm almost ready to move to the sticks to get away from all this nosie. But I know it would just fallow me anyway now a days.
Sorry about the rant.love The channel 👍.
I bought a car battery charger from Amazon only to find it puts out more RF than most of my QRP radios! It wipes out huge chunks of the HF spectrum even at a fair distance. It's shocking to see the amount of untested and often dangerous rubbish that is allowed to be sold on that site and others.
I had one that did exactly the same! Nightmare! Cheers, Ray.
We had a power cut the other day in my area & the bands were as clear as they once were years ago! on the subject of cheap power supplies, i can remember the dodgy 12v power supplies that used to power CB radios back in the 70's/80s that could give you a lethal shock on some types!
at least they were not noisy, best regards.
I'm praying for a power cut so I can run the radio from a battery and see how quite it is. Cheers, Ray.
Never a boring video. Love them. Look fwd to yr nxt.
Thanks!
If you called Ofcom to investigate this, they would say it's perfectly acceptable and leave, they are not fit for purpose and should be held accountable. Trust me I know having had them come out on several occasions and do nothing to stop it. Leave you high and dry and frustrated to say the least. I have done everything I possibly can to combat the noise here at my QTH this is unacceptable, but unfortunately the so-called Regulators will not do anything about it, that's the Problem!!
Agreed, no one cares. ☹️
Good to hear from you Ray as you say noise is a big problem now days. I have heard a similar band of noise moving up and down on 40m. Looking forward to your key video

Hi john, good to hear from you. The key video will be live this afternoon. Cheers, Ray.
I live out in the country here in the US. My normal noise floor is S2. Last year we had a insulator on a power pole about 3 miles down the road go bad. I ended up having to call and file a complaint with the FCC. My power company finally fixed it, but for 10 months I had a solid S6 of a raspy electric shaver noise on most of the bands. I came real close to just unhooking everything and getting out of shortwave listening after 40 years. The 2 things that saved my SWLing were the MFJ 1026, and my DXE-RF-PRO-1B magnetic loop. Both of those let me completly remove the interference. I have a demo of the 1026 on my channel if your interested. Now that the noise is gone, I can use the 1026 and the loop to optimioze signals. But if the interference ever comes back, (and I'm sure it will someday) I hope those 2 things will help again.
It’s nice to hear from you. OK about the insulator. Shame you had to go to the FCC in the end. I’ll check out your channel. Cheers, Ray.
Plasma TV, unfiltered SMPS, etc take your pick. I've got an intercom system where I live and was getting lots of noise from it's SMPS. Thankfully, Ofcom were able to help me. I put loads of clip on ferrites of type 31 material on it's power leads. This reduced the noise considerably on 60m.
Yes, switch mode power supplies are a nightmare. We also have a neighbour with solar panels on the roof... I wonder? Cheers, Ray.
Good morning Ray great video Sir, I have had similar interference too that "moves" on 160 , 80m & 40m, I found it was a pair of CTEK trickle chargers rated at 0.8A (Designed in Sweden BUT made in "China" plus they could be fakes too haha) as the charge cycle / rate decreases (as the battery charges) the interference frequency moves on the bands, plus my neighbour has one too ouch....... as you say there is limited or no RFI filtering in todays in appliances, bring back the British Standards Institute, back in the day I worked for a battery charger & power supply company, where filtering was paramount supplying products to Burndept, Storno, Racal, The Home Office, Thorn Erricsson, Telephone Rentals, Rank Pullin, GPO, Dowty, & NCB to name a few .......... (all linear products of course) we dabbled with the switch mode side of things PSUs & BCs the RF they produced was a big problem .....Cheers Marcus M7WMK (Ex Stoneleigh Electronics design draftsman 1980s)
Thanks Marcus, interesting stuff. Cheers, Ray.
Thanks ray for making this video I won’t have smart meter in my house as there are cheap made crapp they don’t filter anything much , you summed it up in the first 2 mins led lights is bad I have to turn them off when in the shack . Thanks again ray hope you find what it is .
Is contacting offcom asking them what’s transmitting around .
Thanks Paul, all noted about the smart meter. That's a good point. Cheers, Ray.
Good to see you back with another video Ray.
I’m not a HAM but use 11m/CB and listen to a lot of SW… I had a problem a few months ago with a pulsating noise that covered 27 MHz right down to 18 MHz.
There is a very knowledgeable old radio operator guy lives across from me so I asked his advice. He said if it’s local I could track it down with a portable SW receiver and directional antenna. I thought it was something like OTHR with the problems in Eastern Europe but he was right. After a few hours I ended up at a flashing Chicken and Pizza takeaway sign on the high street. The flashing was in time with the pulsating noise.
It disappeared on the Sunday morning when the takeaway closed and didn’t appear again when it opened back up that night. Not sure if there was a faulty bulb or something that got replaced but thankfully the noise has not returned.
Keep the interesting videos coming 🙂
It's nice to hear from you. There's another video coming later today. OK on the pulsating noise. A friend of mine suffers from that on the 144MHz band. Cheers, Ray.
Like you I hear a noise sweeping around on 40. I have given up trying to locate the source. The worst noise I had was from an electric fence, which I was happy to see go.
73 Al
Electric fences can be a nightmare. They are huge aerials! Cheers, Ray.
That’s what being able to “self certify” EMC tests does after a few decades of non-enforcement.
Hi Ray, yes the 7300 Noise Blanker works fantastic. Also the IC7200 has the same performance for Noise Blanker. Yes its sad all the noise makers being introduced into our neighborhoods. These Plasma TVs are one of my main issues for 75 meters. Then on 40 I have some raspy signal every 50 Khz on starting at 7.00 MHz. Raspy buzz. Id like to try a receive magnetic loop to see if I can null out some of it. We will see.
I’d like to try a magnet loop, too. Good idea!
I'm new to this SDR/waterfall malarky. I found the 'donated' laptop RADIATED 8kHz steps; touching the built-in mouse pad produced unstable harmonics, an external mouse helped. The PSU shoves out hash, so the laptop is only effective on batteries; BT powerline adaptors are a hideous source of repetitive noise, and broadband noise from overhead telephone cables which are obviously out of balance (not my line with the ring wire mod) beween frequencies of 8.5 - 12 MHz. An ATU helped some of the worst laptop harmonics, the worst around 155kHz. Adding additional ferrite clamps has not helped at. all. In fact without an aerial the SDR box is electrically quiet and relatively noise free. I'm currently building a DC filter to place in line between the laptop and PSU brick with preserving the earthing.
I also suspect the LED street lighting and other people's computer equipment nearby, judging by the local wifi neighbourhood.
Further afield, I suspect there is jamming from military sources in the Aeronautical mobile segments of the 60M band and there's suspect wideband interference on 11m too that sounds like the 'Woodpecker' over the horizon radar.
Thanks for your interesting comments. I agree about jamming on 60m and the Woodpecker on 11m. There's so much going on these days, RF wise, that it's becoming difficult to find a clear frequency!
@@g4nsj Like you, Top Band was a favourite band with me. A shame that there is so much interference there and on 80m.

Hi ray im chaz 2E0EMN there is a noise being generated that litraly is going through almost the whole HF spectrom it seems to be strongest on 13.882 but it does effect all bands above 13.882 and a fair bit below to around 6 mhz but nowhere near as bad as above 13.882 mhz i found its strongest directions are south easterly and northwesterly on beam antenna even checked around my local area with a portable spectrum analyizer but it effects upto 52mhz at its top frequency most effected 20mtrs 18metrs 15mtrs 12mtrs 10 metrs and strongest mode for sound AM and it makes working dx impossible some have suggested its over the horizon Radar from middle wast iraq iran area and has been going on for quite a while on and off signal strength +50to60carrier on majority of frequencies .but the upper HF bands are mostly impossible to work 11/4/23
That's very interesting, thanks for the info. I'll have a listen on 13.882 and see what I can hear. Cheers, Ray.
Your vids are not boring Ray
Thanks!
You have my sympathy. My main interest these days is the Dutch, Balkan and Greek pirate stations above the mediumwave band. Optimum reception from the Netherlands is the exact opposite direction of the interference that's coming from my neighbours house. Not great when you use a loop. Around 1660 khz is the worst.
Love the Dutch broadcasts! Usually quite strong here, if there's no interference! Cheers, Ray.
Noise has become a terrible blight for many of us. However I seem to have had a lot of success recently with reducing the issue. In my case a vertical antenna away from the house as much as possible as well as common mode chokes on the feeder, the mains supply, the phone line and the satellite downleads has helped to reduce the 10dB over S9 noise on 40m to about S3.
(I know you said you removed the mains from the equation). With phonelines carrying VDSL common mode chokes can help a lot.
FWIW a web resource using TDoA is fantastic for locating some sources. Prior to te recent troubles it was interesting to see various noises on 40m locate to Russian military sites, they have been denying it for all of my lifetime but it is so easy to locate them now. I used a web TDoA to locate a random broadcaster just to see how good it was, the "hotspot" highlighted the correct field.
I cannot remember the website, but a search for KIWI SDR TDoA ought to find it...
Interesting, thanks for posting. Cheers, Ray.
@@g4nsj thank you Ray, your videos always provoke a response. Noise can easily pretty well destroy the hobby. Quite a few people have had remarkable success with loops on the ground for receive, might be worth playing with. I guess many of us regard our aerials as being reciprocal, a good transmit aerial might not produce a good signal to noise ratio on receive. Most of our HF rigs have tons of sensitivity so an inefficient aerial might be fine. One of my rigs has a sub receiver, so you can listen "in stereo" using two antennas, It is suprising at times to hear signals pan across as the low wire wins over the high dipole or vice versa.
QRM has also put a real dampener on SW listening here as well, recent power pole replacement in my street has alleviated the problem somewhat... time for a tree change 🤣
You're right, it really has ruined the hobby. Cheers, Ray.
Sadly for unknown reasons there are various transmission towers on the planet that deliberately transmit noise across the bands to prevent radio communications , it's just yet another problem of recent times , the noise transmissions are synthesized to emulate a similar sound of basic local environmental interference , the interference transmissions are essentially a camouflage unlike the woodpecker , on occasions there are noise transmissions that are received all over the world , these are tower transmitters that are transmitting millions of watts , perhaps from Russia or possibly China ?.
There are many jamming stationms operating throughout the world but I've not heard of the noise transmissions you've described. I wonder why anyone would do that?
Indeed there are jamming stations out there , I've read that there's various military reasons for signal jamming , I'm not all together sure as to why ? , there's also other factors such as cosmic RF from space , I know a few years back there was a global noise on the 11 meter band , it's difficult to pin down the causes due to the global technology factor . Half the battle is to find a remote & high location to obtain a true noise factor , far from the suburbs , sadly we're living on a planet that's full of signal noise , a far cry from the 1950's .
@@g4nsj
Try MFJ-1026 Noise canceller, it worked for me, this device opposes the signal from your main antenna and the signal in antiphase from the second so called noise antenna, which is placed closer to the noise source, and as a result the noise disappears, you just have to manually adjust the intensity of the signals from each antenna and the phase angle
Thanks, I'll see whether I can borrow one locally to check it out. Cheers, Ray.
Hi Ray. got this noise over here in france. changes bands . have been told it could be CODAR and WERA HF Radar. great vids, have learnt alot from them. i use to live in Littlehampton. you might know me. phil.
Hi Phil, it's a small world! I've lived in Worthing for around 65 years so we may well have met at some stage. OK on CODAR and WERA. I'll look into that. Cheers, Ray.
Hi matey for me it's the whole of the 40 metre band . But I found out what it is. It's my Car Battery charger in the garage bottom of garden. Blocks 40 metres up to 4 houses away. It pulse charges the battery. Cheers from old George Ps The noise moves on the band as the battery comes more charged. But more noise when it first put on charge. 🤔
Ah yes, a car battery charger... again! This seems to be a common complaint. Cheers, Ray.
Hi Ray - all kinds of QRM on the amateur bands since the Ukraine conflict kicked off. Some days there are two or more Russian OTH radars operating in the 20 m amateur allocation! I haven't noticed anything particular on 60 m though from here (Surrey). 73 de M1GWZ
Hi Philip, it’s nice to hear from you. I’ve not heard anything out of the ordinary on 60m either. My problem is local QRM. Cheers, Ray.
If you have a switching power supply it could be causing the noise where the peaks are as well as the noise that moves up and down the band.
Thanks Patrick.
noise is every where now days, you can use a Trifield RF meter and the readings are out the roof
I noticed the narrow band noise readings you show (I call Fence Post) because that's what they look like, they were space a few Khz apart and it looked like they were the same Khz apart across the scope
Did you measure how many Khz apart they were? That might explain where the noise is from
I haven’t as yet but I’ll do that when I get a minute.
Can't see that particular issue here in the West Midland. One of the worst things I see here is from some in ceiling led spot lights I purchased recently for the small bedroom. When they are switched on they are terrible I have noticed. I agree lots of cheap electronics from abroad, absolute rubbish mains filtering if at all!
I agree, absolute rubbing from abroad. It's time it was sorted out. Cheers, Ray.
At QRP power (10 watts) the local noise floor is so great no one hears me - or I them - at any distance . I am going to have to go portable I guess. M7BLC
Sadly, I think that’s our only option.
I have S8 noise 160 to 20m from the internet over the telephone wire. Ofcom came here for 3 hours investigating my neighbours wires and said it was my phone line possibly becoming unbalanced and radiating. BT will charge me for taking down their offending line.
Strangely 60m is okay. Most other operating had been on 2m.
I almost gave up radio but now the higher frequencies are open it changed my mind.
G4GHB
Hi Bill, BT will charge you for taking down their offending line. Hmm, that's not right!
@@g4nsj They don't accept it is faulty. I didn't get an engineer, only a standard letter by a secretary who knows nothing.
Same from the Minister of Telecomms and Broadband, telling me to get in touch with my internet provider. That's Virgin, nothing to do with the problem which is BT.
@@bill-2018 Typical! Sometimes, it's a never ending battle.
have you tried a skyloop antenna?
I've tried various antennas but not that one. Thanks for the idea. Cheers, Ray.
i get noise like this on hf,,i use a noise phase unit to tackle it seems to be local to me but very similar to this noise in the vid,,,i put it down to phone chargers,switch mode power supplies in tv sets and anything else that can be plugged in to a mains supp;y,,,,,noise on hf is getting sos bad some people have had to give up the hobby or go mobile or portable,,,ig the old RA was still in charge this would never have happened back in the day,,,remember when we got a no fee licence most of our protection went with it.,,,no fee no contract.
I know a couple of people who only operate mobile now due to noise at home. Such a shame.
Hi Ray i agree with you, i have a load of noise here, i have something that looks like that on 4mts, every other channel is clear, i have a clicking noise on 6mts the n/b gets rid of most of that, i have terrible noise across the CB band, and i have a lot of noise on 20mts, i dont use anything below 20mts so that sounds clear to me, i have no proper aerial, the 20mt noise is worse when i turn my yagi n/w toward Stansted Airport, thats the direction to USA if i get strong enough signals it will get over it, i think noises are caused by Chines psu's etc, arching on electric light poles or pylons, central heating thermostats, Solar panel inverters, stuff like that, is it worth getting Ofcom in?, you will prob never cure it, could be local most likely is, and Computers can cause it, but you donr the right thing by turning your mains off and trying that, flourecent lights is another one...switch mode psu prob the worst....their in PC's..i am out in a small village so could be worse i guess....good luck from Fred g4vvq Nr Chelmsford.
SMPS my neighbours EV charger for there VW ID3 destroys HF in similar part of the spectrum,Power Factor Correction?
Ive tryed everything myself 🤷♂️ glad iam not the only one
I'm sure there are many of us! Cheers, Ray.
Is there a time frame when the noise is higher than others ?
Not really. It seems to be constant.
To find the noise,I got a SDR dongle for my phone. I used it with a directional antenna to find nosie around the house and my block. Worked great, maybe you can do something like that??
Thanks, great idea! 👍
Seems to me that EMC regulations don’t mean a thing with all these imports from China you can buy on eBay. They don’t conform to electrical rules, much less EMC rules. I get buzzing noises in various parts of the HF bands, sometimes wander, some don’t. Long had a high noise level on 40M but oddly, I’ve been hearing SSTV in 7171 in recent weeks. On an indoor aerial run around my room! My listening is mostly on my vintage FRG-7 which is going well for a 4t year old set. I have banned switch mode wall warts from my room and my devices are charged from car 12V USB adaptors running from my 15A bench power supply. The power supply is a transformer type, but it does get into audio isolation transformers sometimes. 73 de VK3YWB Wenlock
I have a Yaesu FRG7. Old but fantastic! Cheers, Ray.
Hi Ray, are you getting a lot of noise on the hf bands at the moment, mainly 10 to 20mts, i have an Icom IC 7300 with a waterfall scope on and you can see what looks like giant mushrooms, one of the worst places is 28.500 all sorts of noise, might be high sunspot acivity Fred g4vvq.
Hi Fred, nice to hear from you. My noise is all below about 8MHz. Upwards from there is pretty much noise free. Some people locally are experiencing noise on 2 and 4 metres. I don’t know what’s going on! Cheers, Ray.
Street lights can interfere badly. What part of the UK you in? When I was in London I herd many strange things. -73's
In on the south coast near Brighton. Our street light seem to be OK but I do know people who have bad interference from them. 73, Ray.
Any update on this ? Did you ever get to the bottom of it ?
Yes, it was a neighbour's power supply. There's still some interference from another source that I need to track down. Cheers, Ray. .
Have you seen the 1996 film "The Arrival"? Perhaps this can provide some answers.
I haven’t. I’ll take a look.
Hello Ray
Thank you for sharing .
This may sound rather odd , but I've read that there's certain noise entering earth from space , it's all rather mysterious ?.
There's also the Earth's natural noise or music as it's sometimes called.
This is actualy one reason i haw not converted everything into LEDs in my home yet, i actualy still had to use fluorescent lamps in my kitchen for this reason, i know there are better LED dreivers which don't, but i for me it's realy not worth the effort for the little i use that light as long as the old armatures still works.
I agree 100%. All this LED stuff is a good idea but it causes so much interference. Cheers, Ray.
The 2d band of noise sounds like plasma television,but if its not there all the time Ray, (as if the television is on most of the day) Goodness knows.My next door neighbour has a plasma television,and it kills 80 mts...........We are very good friends so i live and let live :)
Plasma TVs are a real pain, you're right. I don't think our neighbours have one but I will check. Cheers, Ray.
Hi Ray,yes ok, well i have a 7300 with a scope on, and on 4 meters i get a whole row of spikes, therefore when i listen on there i get noise on every other channel, on 2 and 70 i dimdnt have any trouble, but just recently on 20m upwards i get what looks like mushrooms on there, i do have a 3 element yagi, could be deliberate qrm from Russia...i sometimes hear the reminence of the woodpecker...we have a thing nearby called Kelvedon Hatch secret nuclear bunker, and they have an sdr system there, the vhf/uhf is ok but the hf to me sounds terrible..so maybe its not local to me...Fred
Hi Fred, you could be right about deliberate qrm from Russia. Anything is possible these days! OK on Kelvedon Hatch, I've heard of that. I wonder what they get up to. Great to hear from you, as always. Cheers, Ray.
That group of QRM is almost certainly coming from one source, likely an unstable switched-mode power supply or mains inverter/charger.. Get yourself a QRM eliminator and take some time to learn to use it properly....it is an acquired skill. The noise pick-up antenna only needs to be 10 feet of wire in the room/roof space, but ideally somewhere where it will get the QRM signal better than the real DX stations (ideally not a good DX antenna at all). It needs some practice to use it well but with time you'll be able to null out almost any single-point QRM.
73 Steve G1XOW
Hi Steve, you're right. I've now tracked it down to a switched mode supply. I might look into getting a QRM eliminator for future use. Cheers for now, Ray.
I quite often listen to Volmet frequencies to gauge condx on 60m. Can't say I have heard that around 5.45MHz. My QTH is west central Scotland. Also, if that noise was causing significant interference to aircraft reception of Volmet, assume that Ofcom would have been onto it ages ago? Therefore, suspect it is local. Wonder what kind of antenna you used when you tried to locate it?
As per other comments, it is a losing battle. We are drowning in a quagimire of RFI. As you say, only affects a minority, and I suspect our rights were eroded when we stopped paying a license fee. Therefore, suspect absolutely nothing will be done.
When I tried to locate the noise, I had a portable radio with a ferrite rod on 80 metres. It was a great little radio. It used the ferrite rod up to about 4MHz. Cheers, Ray.
@@g4nsj You would think the ferrite rod would give you some idea of the direction (or directions 180° apart). If you could only get one those 80m fox hunt receivers that worked on 60m this might help? Perhaps you could mod an 80m set to work 60m?
Hi Ray my next door neighbour has just fitted cctv cameras they make a noise just like you have been describing .
I live up near Hull and I get those other lines of nose along the band like you.
Regards Dave .

Yes unfortunately this noise problem on the HF bands is everywhere Ray.Thankfully I can operate mobile from noise free environments such as Beachy Head etc but as you say in this modern world we have imported so much junk from China ie power supplies etc and also now have led street lights etc etc and it all adds to this problem.
73.G7HFS/PA3IKH
I couldn’t agree more. I don’t think there will ever be noise free bands anymore.
A laptop charger was the source of my interference.
Glad you found the culprit.
Wall warts, plasma tvs, LED lights, create static for radio frequency. Also power transformers on telephone poles could also do it too. Power wires with cracks that get moisture in it can do it. Time to move out to the country!
I'd love to move to a lonely spot in the country. Bliss! I'll let you know if I win the lottery! Cheers, Ray.
shifting blanket un sound = uVw !?!.....GOODluckMAN
I get it on 20 meters to on my ftdx10 i see it more on my external monitor
20 metres is fine here so that's interesting. Cheers, Ray.
Ive got noise coming from the power supply in my PC's ( have to turn them off when on HF ) as well as from my 60 inch plasma tv as well as the inferior switching power supplies and cfl light bulbs . Its disgusting just like the LED Headlights on cars so bright they blind you at night and its all said to be in the name of progress...humbug...disgusting as you say and I have to say the more technology moves forward the more problems it creates. Oh yes then there is power line noise due to how it is generated these days and the noise from the tv cable companies lines overhead and their digital amplifiers..
You’re right, noise sources are many and there are more popping up every day!
Ofcom should be inspecting smps and other potential sources of rfi before they are allowed to be imported. They should also run periodic checks thereafter. There really isn't any excuse for this.
I'm not sure that Ofcom bother to do anything these days. Cheers, Ray.
Try a yagi antenna with your HT and a attenuator maybe thay mite help
Good idea!
Perhaps that what 'they' want?
I get the same thing at times🤔
Interesting, thanks. Cheers, Ray.
I have the same noise on my short wave radio at those frequencies. Seems strange to me that very severe weather events have become more frequent in that time period. HAARP comes to mind.
You may well be right! Cheers, Ray.
HAARPS range is limited vertically between 70 - 350km and measures the activity of frequency ranges people don't even broadcast on for ionospheric processes. Please, don't bring uneducated conspiracy nonsense into this.
looks like a dirty switch mode power supply problem to me.
Yes, I think you're right.
Try a noise phase unit,,i have had great results.
Thanks, I’ll try it.
Thats meters.
That would drive me nuts. No idea but it seems to generate harmonics but changing frequencies is bizarre. Cheap rubbish electronics from China is in every country, they don't give a damn. Maybe relocate to an isolated farm.🤔🤷♂️
It does drive me nuts! I might take up fishing! Cheers, Ray.
That's your government setting up to jam all your HAM bands for the Great Collapse.
Naw, it's just coincide, right?
Seeing we share the band with the military....god only know what the get upto....I do have a neighbour (Navy) who has told me snippets.
Also with a war not so far away,....anything can be expected.
It is sad though that our bands are so bad these days.
I to hate the Far East Crap.
OK about the military. That's interesting, thanks. Cheers, Ray.
Mains borne 21st century neighbour crap, hence so difficult to DF. Just wait till they all start charging their EVs.☹
