Hi All,
Well here is the update, next door turned there Wi Fi box and there Tivo TV box off tonight at 5:40pm and all of the interference has gone, not one glitch all night sound or otherwise.
They are back at 8 and turning it back on so i expect it will return.
Next step tomorrow i have asked them to leave the Tivo TV box on when they are out to see if i get the interference.
At least i know it's coming from next door and they are being helpful.
So its down to Tivo Box or WiFi i think or maybe there TV but they don't watch it much and it was off when i visited and still had the problem so i don't think its that.
Again thanks for all the advice.
Kind Regards
Rob

rob: Well, I suppose that this is a positive indication that the problem "is" definitely caused by your neighbours equipment, although if the interference hadn't stopped when your neighbours killed the power to those devices then this would have created a really mind baffling problem, because as far as I am concerned all of the tests you carried out were meaningful including the RFI detection sweep of the wall using the portable radio.
However, the next stage is to single out which one of the two devices referred to is responsible for the problem albeit that the Virgin box is the main suspect, singling them out simply done by powering them up one at a time.

Hi All,
Another update, next door have left the Tivo TV box on this morning and switched off the Wi Fi and i have had no interference again, so it would seem that the culprit is the Wi Fi box or maybe there TV (but this is normally off so would not expect that).
Next door still have there interference on there Tivo box too and i have suggested that they turn off the Wi Fi box and see if there issue also go's away.
Next door have contacted virgin media again (before this latest test) and they are sending out a "Principal Technician" to look at there issue and mine.
Just glad the neighbors are understanding about it.
Cheers again for all the advice, i will keep you up to date.

rob: I had also intended adding to my previous reply that out of the two devices mentioned the Wi-Fi box is is only one of the two that is designed to emit a radio signal, whereas anything radiating from the Virgin box would be unintentional in the form of interference, however the problem should now be easily solved should your neighbour be willing to purchased another brand of Wi-Fi device, my reason for stating another brand is just in case whatever they are using has a reputation for being responsible for this type of problem.
Maybe you could enquire as to the brand / model of device they are using?

Hi jb38,
The Wi fi box is a virginmedia superhub, the same as the one in my house. Mines a long way from my tv.
i am hoping that Virgin Media can now sort this out.
regards
Rob

In that case, as your own VM hub is installed a good distance away from the TV then it wont really be known whether or not its also capable of causing similar problems to that experienced from your next door neighbours, as it might well do!, but though it would be interesting to know the result of an interference level comparison test between your neighbours hub and your own by using the same portable radio as before when positioned at a fixed distance from the hub, e.g: from exactly 3 or 4 feet above it, noting the result and then repeating the procedure on your neighbours hub.
The main aspect about this type of test being accuracy, that is ensuring that the radio is positioned in exactly the same spot in both locations and that no alterations are made to the tuning or volume settings on the radio between the two households.

Hi jb38,
Well i don't really have the opportunity to do the suggested test, however i have put the AM Radio near to my Wi Fi router and there is some noise coming from it as you would expect but not loads, however the power supply adapter was very noisy, if they have this against the wall next door which i think they may have it could be the issue.
Anyway i an hoping that Virgin Media will now take this seriously and investigate the issue correctly.
Will keep you posted
Rob

rob: Yes, most modern light weight power adaptors are what's known as SMPS devices, short for "switched mode power supplies" and which in practical terms are high frequency power converters, most of being prone to emitting high levels of RFI across a wide band of frequencies albeit only over very short distances of around a maximum of 3 feet or so.

Rob, I used to travel to the Far East to do technical appraisals on SMPS and their manufactures. There is a lot of product that claim to meet the standards for conducted and radiated noise - and even have the right markings - but in fact do not.
Often the SMPS has the space on the pc board for the conducted EMI filters but the components are just not fitted (cost saving?).
Even big name buyers of SMPS get caught out unless they use a well respected assurance company to vet each batch before shipment. VM may be very glad that you have identified a faulty batch or a poor supplier.
I have one here that meets the standards but still causes interference on an FM radio when plugged into a socket which is on a spur from the one powering the SMPS.
Similar problems are arising now from the so called Power Line Adaptors which use mains wiring to give internet access to a pc that is remote from the router.
Glad you are finally getting somewhere.
