UKQRM Video showing the interference caused by BT Vision

[rukowski]

good work

[Welshkiteflyer]

have you resolved this yet Mike. Ceri GW0jcb

[stupidjunk978]

Wow, you're impersonating GCHQ now? Expect an arrest for fraud soon

[mikesndbs]

@stupidjunk978 what are you talking about LOL I am not impersonating anyone at all!

[Meduzi]

@stupidjunk978 Are you senile, or just a regular idiot?

[bben95]

Where did you get the portable reciever from? The one that has a sticker saying 9 bands on?

[mikesndbs]

@bben95 Tandy shop back in 1990

[m3xlipat]

its food for thought my neigbours getting a bt home hub with a tv package my hf spectum (0/30mhz ) is fine at the min fingers crossed a do not get that noise



[BDGregory]

You could have BT Vision if you wished. You'd just have to run a proper CAT5 Ethernet cable from the BT Hub to the TV box.

[prototype9000]

why not use groundwave radio you dont get that interference or just dont use the channels that are affected

[mikesndbs]

No, none of that is possible.

All channels are affected all the time.

[BDGregory]

These things use ALL the interesting frequencies. No other frequencies travel so far without the aid of satellites or something.

[Meduzi]

@prototype9000 What an incredibly dumb reply! Do you dress yourself?

[skwira001]

Check out MoCa from Netgear and the Ethernet over phone line bridge from Corinex.

[JohnnyX50]

I just looked at specs of PLT device. Offers 200Mbps of data transfer. My DLINK Wireless router offers me 54Mbps on my pc and I still get the full 1000KB/s download speed offered by my ISP, with full encryption and security enabled, so what is the point? Just an easy way for the signal to get intercepted by the men in black I assume as all they need is a SW receiver. I just don't see any real use for a PLT that a wireless router can't offer.

[JohnnyX50]

What better way to deny access to free information and/or reception of signals we maybe shouldn't be listening to on SW than instead of making Jammers, just get the public to jam the signals locally with their own money. The BBC, and BT work hand in hand with the Government on a variety of projects and I hate all 3 of those organisations. I will support the UKQRM group in any way I can.

[allcingeye]

Cheers for this post I have added it to my site no way should this be allowed I just had A lok on the RSGB web site and found the pdf they had sent to Ofcom about this problem. if there is Any way you feel I may be of some help I will do my best .

My best allcingeye

[maxyboy0]

here here well said old boy tell bt to go get fucked . although saying that i use a bt home hub and get nothing on my radio from that. but my old sony trinitron tv gives me 5 quid of shit through out the 10 -11 meter band .what a shitter. down with sony.

[BDGregory]

At least you have the power to switch off your TV when you want to listen to HF.

[vilijemk]

Seems to me its all a plan to push free radio communications away, for us people to pay for everything on this world :(

and on the side even fill our heads with all this "noise"

[mikesndbs]

Just wanted to report that since the making of this video my neighbours have become good neighbours! but quite clearly another aspect of this crappy technology is bad neighbour relations!

STOP PRESS does PLT slow down broadband? seems like it

[sparkdetect]

Isn't it amazing what big business gets away with...

[ian9outof10]

Mike, can you confirm if this problem is caused by ALL Homeplug devices?

I've spoken to Solwise, who use the intellion chipset, they tell me interference from these devices should be lower than the type provided in the BT Vision system.

Is there any way for these two technologies to live together, or does one have to die so the other can live?

Best Wishes,

Ian

[mikesndbs]

Hi Ian, well yes its all down to HPA or UPA the UPA standard that BT/ Comtrend use is terrible, the HPA that Solwise use is just very bad. There is no way for PLT to live with HF all the time PLT uses the HF frequency range, thats the whole issue here, the HF range is in full use right across the globe, PLT currently is just like a very bad pirate radio jamming everything! They need to be allocated a range just for themselves and not one thats in use already like HF

[ian9outof10]

I am very interested in this stuff. I must admit, I use Homeplug because I have no choice. I live in a rented house, and can't run cable, and WiFi just isn't an option.

Is it possible for the companies behind this technology to make them either less noisy, or use a different frequency band?

[mikesndbs]

Yes it is possible, but all the time they can get away with selling this stuff they will. The best thing to do would be to complain you can't use your shortwave radio now and send this to trading standards as you will see the PLT will say it complies with EMC and other directives when it clearly does not.

Much more information can be had from our web site 'ukqrm' just google us :-)

[laurdy]

i know they get away with this stuff because OFCOM just like customs only care about commercial stuff for example OFCOM WOULD do something about it if it was on FM or DAB band. also customs let through loads of stuff that they are not meant to like when i was in "a well Known Supermarket" every DVD player, Freeview Box and Satalite Tuner they had in stock was below standard to the point that it was not legal for sale in this country

[timvid49]

I have this same interferance here it started a few months ago,it ruins my shortwave reception above 4mhz .

[mikesndbs]

OK, well it can be sorted out for you! please join UKQRM on Yahoo groups and we will show you how to make a complaint to Ofcom! its no risk and they will sort it out.

[timvid49]

Thankyou Ive joined the group.I think the interferance is from the flat next door to me.I know he has a BT hub.I will have to investagate further.

[G0IFI]

That's horrendous Mike, I truly wish you the best in having your hobby back soon, and getting these bloody horrible devices properly screened and suppressed. If we amateurs caused problems like that locally we'd be closed down.

[robocog]

Hi Mike, great vid and very well put together

Thanks for sharing it and highlighting the problem

I have been lucky so far here, and hopefully with the work and efforts you guys are putting in I hopefully never will

Regards

Rob

[pmrukk]

I tried to join your group but was turned down, what does it take to become a member of your group?.

[mikesndbs]

Hi, UKQRM is very busy now and has several moderators, new applicants must provide information as specified on the home page.

Not sure if this was why, but this is just to make sure people who join are genuine.

Try again, I'll keep an eye out for you.

Mike UKQRM Owner

[MARKGM20877]

Hi Mike see the video i have posted...the MFJ-1026 does work in combating BTV cheers Mark

[jongruner]

I can understand your frustration with such devices, but the BT Hub or any wireless device is doing what it's supposed to do, emitting a signal so the user has wireless access around their home and outside the property. BT Vision has many benefits to people like myself who live 5 miles away from a video store and I'm sure other subscribers benefit too. Why should a primitive technology take priority over modern digital technology?

[mikesndbs]

(part 1)

Well very clearly you don't understand my frustration at all!

The BT Home hub wireless is not the issue here at all! what is the issue is the power line adaptors used to send data and TV around your house via the mains wires.

By their own claim, they are not designed to transmit outside of the house.

The fact that they do means they are badly designed and I feel do not comply with regulations.

[mikesndbs]

(part 2)

I am very insulted that you would call shortwave primitive, once again is shows your complete lack of understanding of the situation!

For example I could ask on the flip side why an established busy communications medium should be destroyed by a few nerds playing with video games and watching movies!!!!

[jongruner]

:) I'm not a nerd;) I don't think any device be it digital or otherwise can control where it's signals go. Radio signals from earth leak out into space after all. Maybe in time the digital technology will improve? in turn reducing such issues.

All the best.

[mikesndbs]

Ok, then I am not someone using outdated tech either ok? Please take a look at our web site and the YouTube video here called 'Shortwave Radio and Power Line Transmissions (UKQRM)' which explains the problem simply. You should also understand that Ofcom are carrying out tests on the PLTs.

Our web site is three ukqrm dot org

Cheers

[mikesndbs]

Just noticed your comment about radio signals! Yes they do but power line adaptors are not supposed to be radios! the fact that they are is the whole issue!

[G0IFI]

The BTVision device isn't supposed to radiate crap all over those frequencies, that's the issue. Like all other RF devices, it should keep its radiation within its designated bandwidth. The BTVision fails to comply, miserably, and in the USA the FCC would ban it.

[BDGregory]

You should really keep your high speed digital signals in a cable designed to carry them and not blast them at high power down your existing unscreened mains cable on frequencies allocated by international agreement for other purposes.

[BDGregory]

Shortwave is used extensively to provide vital communications from isolated areas. Aircraft use it to stay in touch when flying over large oceans. There is even digital radio on shortwave.

[2e0hky]

Thanks for the very interesting video and for your efforts to combat the abusive and irresponsible implementation of this technology.

[mikesndbs]

Thanks :-) it helps to get comments like this!

Have you joined UKQRM on Yahoo groups?

[apolloscam]

Sue and get rich.

[dingle1672]

does it interfear with other people who live near u to haha its like jacking a radio station from where people live near u weird noise

[techcf]

This is just horrible! Great video though.

[Adriano9966]

sorry run out of space ...if i turn my rf gain down slightly my equiptment is now at least usable and i can tolerate the noise level because the signal is lower (below static level)however it is a nuisance and i joined your group several days ago hope my experience helps someone else thank you once again

[mikesndbs]

Thanks for the update.

Please complain to Ofcom about the one you can still hear! you could use my method to track it down.

Cheers

[Adriano9966]

used the same method again this person was very helpful indeed and allowed me to hard wire his set up with an ethernet cable result no more qrm from bt vision however i am surounded by houses and apartments total 86 chances are there will be someone else so the very next occasion im writing to ofcom these devices should be withdrawn and go where they belong in the dustbin

[Adriano9966]

I promised i would keep you informed mike saturday i spent three hours on the phone to bt as they passed me around different call centres in the end i lost my patience and asked to speak to a senior manager this power line adaptor has now been removed however due to the fact i have a half wave lambda antenna i can still receive someone else further away with the same dreaded powerline adaptor

[guntertimb]

What a horrible sound! This needs to be stopped before it happens here in the U.S. if it isn't already happening in the metropolitan areas.

[Adriano9966]

i would like to thank you mike you really helped me I spent £150 to put up a half wave cb radio antenna only to have the reception wiped out by this noise .i copied what you did in your video clip and i was able to determine which neighbour had bt vision im now waiting for the outcome he said he will ring them up tommorow morning to replace the power line adaptor...for a non interfering one ill keep you informed

[mikesndbs]

Thank you, this makes it all worthwhile! I hope you get a good outcome. If there is any delay please report the matter to Ofcom, they need to know how widespread this problem is! Also if you have not already please join the UKQRM group as your experience would help others. Regards Mike

[Adriano9966]

success i rang telecom and complained and so did my neighbour they say they will test the equiptment and try to change the frequency (this i doubt will work) then they said that if that does nt work they might substitute the power line adaptor for an ethernet cable which i believe is a much better option

[mikesndbs]

From the The Electromagnetic Compatibility Regulations 2006

(a) the electromagnetic disturbance it generates does not exceed a level above which radio and telecommunications equipment or other equipment cannot operate as intended;

So our radios then!!!!!

[nickthesafe]

This is certainly spectrum abuse! What noddies at BT thought this up?. I thought I had it bad with a 24/7 QRM hammering from a neighbours' ill maintained TV and Xbox game...but this is much worse and needs to be stamped out.

[pruefziffer]

Very good and interesting movie clip... good luck on getting rid off that QRM!

[callum742]

Your absolutely right.

BT Vision could be the death of HF radio.

[VictoreCelia]

very interesting...
