    Bought Aura 2 months ago to replace 9yr old Fox T2. TV is Sony Bravia. I get occasional picture breakup on all channels. Higher channels like Yesterday get signal too weak. I have done Manual tune with instructions from Humax for my transmitter.

    Fox T2 still perfect all channels using same aerial and TV. All connections HDMI. I have set HDMI resolution 1080p 60HZ. Why is the Aura worse than a Fox T2 ?

    Yes Im in same boat been waiting for Xmas to pass before asking Humax to exchange for one that works. Lots of threads on forum about poor Aura tuners.

    I’ve chatted with Humax. The reason for poor signal that Aura can’t cope with is that it has more tuners(3) to share the incoming signal with. Fox T2 only 2 tuners to share signal and so is better off. Does this sound reasonable ?

    The AURA has the same number of tuners as the FVP4000/5000 which came after the HDR Fox T2, but there does seem to be an issue with some AURA units.

    Luckily mine has been great and I have not experienced any kind of picture/signal issue. Some people have returned theirs and the replacement has been fine.

    Yes the 5000 works fine with 3 tuners .There talking a lot of nonsense I’m afraid i.e. admitting we made a box with 3 tuners so don’t expect it to work correctly. Just delaying tactics I’m afraid . I’m afraid help desks these days are anything but.

    Mind you I did contact a shower help desk about a design fault in a shower cover button which breaks over time. No argument he put one in the post to me immediately!

    Well Humax responded quickly to my enquires mails whizzing back and forth today as they had me do a manual tune etc and give signal/ quality figures ,so no hanging about waiting for a reply.

    Finally it was decided a replacement would be sent , and another Humax dept will contact me.

    So if you have a problem e mail seems the way to go.

    NASA have just launched a telescope to view the furthest reaches of the universe. Humax are saying that its not possible to amplify the aerial signal of the AURA so that it can be shared between 3 tuners. So NO it does not sound reasonable at all.

    It seems as though the Aura was rushed to be launched as opposed to getting the product right and fit for purpose and I have 2 of them!

    Thanks for all replies. I’m reluctant to try and swap the hardware, as I’ve 2 months of recordings on the disk by now. Currently using an aerial booster, and main channels now perfect to view, except for Drama downwards. I have a very local ‘lite’ transmitter. So my aerial is pointing to a distant one Stockland Hill with all channels.

    My plan is to get local TV shop/engineers to try and get the best out of it – better aerial, check/new cabling, using their instruments, whatever it takes.

    Before you launch into a large amount of expenditure (which is what Humax suggested to me) – look for the second post in the thread “Aura Signal Problems”. In the second message of this thread is a test procedure which I think is attributed to user havenview (appologies if not).

    In this test he describes how to make SD channels go right and then wrong reproducibly.

    Try it and see if this is the problem you are experiencing (i.e. a bug in the Aura software)

    Yes in my e mails to humax I mentioned havenviews finding and suggested possible software update. But no response as I think if software update could correct this they would have done this earlier as this problem must be costing them.

    If all goes well my aura will be changed over by courier at my address. Yes I will lose my recordings but won,t be without box.

    I have run though havenviews test. My fragmented channel Drama was cured by a Reboot and then went bad again after moving channels. I do have a few channels that say “lack of signal” across the screen. I cannot resurrect them by a reboot. I have another problem in that the socket/cables are touchy. Moving them slightly freezes current channel on and off (other channels OK until I touch cables.) I cannot live with all this hassle, so email sent this AM. Humax have never answered my previous emails claiming ‘lost’ :((

    I had no problem with contact by e mail

    Humax Customer Support <uksupport@humaxonline.co.uk>

    So don,t give up keep up the pressure. This is what they asked of me.

    “Thank you for contacting Humax, I’m sorry to hear about the trouble you’re experiencing with your Humax equipment. I will need a signal reading from SD stations, press the Freeview / home button > settings > channel and broadcast > signal test, send me the strength and quality, in settings also go to Freeview play preferences > system settings > system information, send me the firmware version?”

    Then I had to do a manual retune at their request but got me nowhere as I knew it would.

    Good Luck lets hope all this hassle were having pays off in the long run?

    Worth reposting this, as it could be cross-interference during periods of high pressure (i. e. today)

    A log periodic aerial pointing directly at the transmitter seems to be helpful in certain situations..

    davidrew – 1 mnth ago  » 

    My personal findings are that the Aura does seem to have sensitive tuners in some signal situations. I do know, having had communication with Humax, that they are different to their previous models. I had a 5000T and had no issues apart from too much signal causing pixilation which I fixed with an attenuator. The Aura was a direct swap for the 5000T so I expected that the existing TV signal distribution would work. I am 14.3 miles from the nearest main transmitter with a clear line of sight. There are two other main transmitters, one at 35 miles (22 degrees different) and the other 61 miles (142 degrees different)

    My symptoms have been brief pixilation events (2 to 3 seconds) on HD channels. Signal wise I did have 100% quality and 100% strength on BBC1HD. I throttled this back to around 90% strength with an attenuator but could not go any further as Channel 55 (COM7) dropped off as it is transmitted at much lower power.

    After a lot of research, and evaluation of a second test Aura unit supplied by Humax, I came to the conclusion it must be something in the signal reception path upsetting the Aura.

    What finally seems to have fixed it for me was changing the aerial which is loft mounted. My original was a SLX Digidome omni-directional which went in to a powered Labgear distribution, this created a lot of signal boost (which was fine before analogue was switched off) so I originally removed the Labgear powered distribution, thinking reducing the boost would fix it, but this made no difference. As the SLX is Omni-directional I was also concerned about potential interference from the other transmitters and any other sources hence the decision to try a new aerial.I now have a Labgear 27885 Log-periodic aerial which is powered as it is still loft mounted. Log-periodic aerials are highly directional and have more constant characteristics over the frequency range, they are also a lot less prone to reflection interference. So far in 3 weeks I have not observed a single picture issue (I was seeing 4 or 5 a week on recordings) and the signal strength across all channels is much more consistent even on Channel 55 (COM7).

    From all my research finding the optimal set-up can be complicated and depends on many factors. For instance, a lot of installations have inappropriate aerials from when analogue was still being transmitted and digital was on much lower power and lots of high gain antenna were fitted. Another factor can be older Yagi aerials in the wrong group which can just pick up the local signal or a fringe one.

    My conclusion is that the Aura is not always to blame, it looks as if my signal reception kit was and, in the past, I might have just got away with it.

    Yes I did think of follow your lead ,with amp and new aerial in the loft which would have been easy for me to do ,but I live in a strong signal area so shouldn’t have to do this.

    Ironically I got fed up of no channel 4 HD on Freesat ,and went for the aura as I also wanted a 3 tuner box. And then what happens channel 4HD comes back on Freesat.

    Just hope it new exchange box comes good?
