The photo was posted in an attempt to confirm that I was using the correct type and grade of attenuator.
There are many posts about tuning issues, and an equal number claiming that an attenuator will fix the problem. In my case it did not so I was asking if it was the correct specification.
The forum allows photographs, and so this seemed like the right way to confirm.
Sorry you found issue.

As far as I can see the attenuator should be OK. It remains true that on earlier Humax boxes using an attenuator does help in locations with high signal strength; sadly they appear less helpful on the Aura boxes. I did at least attempt to offer a solution. There was a case a few weeks ago when this sort of problem was traced to a faulty amplifier in the aerial cabling. Any amplifiers in your setup?
No, I don’t have any amplifiers anywhere, hence 3 aerials to avoid splitting the signal too much. In fact the Aura has it’s own aerial.
Interestingly, the aerial pass through from the Aura goes to the Samsung TV (which the Aura is connected to by a HDMI) and if I use that TV as the tuner, I get all the channels, so I was wondering if the Aura boosts the signal, and if so, would a booster before the Aura help?
Unfortunately I don’t have one to try and would have to order one.
Make sure, before doing a manual retune, that you specifically delete ALL the currently saved lcn’s from c55 otherwise (if it is anything like the 4000t/5000t) the new search won’t always overwrite the stored information.

I will do that in future.
I have had a read up on the dB scale used for signal strength, and it seems that it is not a linear scale. The signal strength doubles every 3dB increase in value. If so, then a very small increase in dB’s would make a massive difference in difference to the signal.
Since I know that lowering the signal doesn’t help me, then I think it’s definitely worth a try with a booster. The OneForAll booster adds 23dB which sounds like it may be too much, so I think I will look for an adjustable booster.
If the signal strength is 100% then what is the point of booster? Are you receiving Ch55 from two transmitters? Did you retune after adding the variable attenuator? I would try reducing the signal strength to about 75% then retune.
I could be receiving signals from 2 transmitters, as I have received channels from the Welsh transmitter Moel-y-Parc in the past (winter hill is the correct transmitter). In the past, I have had duplicate channels, one with regional Welsh programs. I have no Welsh programs, how would I tell if I had interference from the other transmitter? Again it does not affect any other receiver in the house.
I did retune each time I changed the signal strength, but I did not clear old channels first as suggested by an earlier poster.
The point of boosting the signal when at 100% strength is that I do not know what 100% means. If I moved closer to the transmitter, then the signal would be stronger, but it would still read 100%. Obviously software decides what 100% is, and there is obviously a point at which it decides everything above this level is 100%. I have a feeling, that that the calculation/limit may be wrong. Hence my original question.
I have just bought a Humax Aura despite reading a few negative reviews I have been a Humax user for many years. I love the speed of the Aura but I am having the signal and quality problems others describe. It is particularly noticeable on The Yesterday channel (26 in Brighton) with bad pixilation and break up. Quality fluctuations down to 65% then up to 100%. I have bought an attenuator (the SAC one pictured earlier). I have tried turning down the signal but I’m not sure how far to go. It doesn’t really seem to improve the signal quality. Stil fluctuating! I have been in touch with Humax but no answer on this yet. Also the Aura app won’t accept the ref code on my iPhone! Might be going back to shop

My reading of the release notes for the latest Beta test software is that there are changes which may help you when the software is finally released.

The beta firmware does not solve the problem of varying signal quality on DVB-T muxes. The release notes mention DVB-T2.
Just got a reply from Humax. They recommend a reset. Which is a pain as have to re sign in on iPlayer’s and uktv Play etc. Have done it all. Guess what the app still says invalid code. Will have to wait for software update. Sorry if strayed off main topic.
The reset does seem to have helped signal. Have removed attenuator. Does not work for me but only wasted £5. The signal strength on ch33 is 96% and quality 100%

It is the SD Channels that have the signal quality problems as you say. The HD DVB-T2 are fine. I have spoken to Richersounds and they suggested calling Humax helpline. They will replace the box if is a duff unit. My second full reset seems to have helped signal quality.
Shame about the app invalid code. But Humax apps have never really worked in my experience.

I too have some signal issues on SD channels but I assumed that it was down to the aura tuners being a bit more sensitive. I didn’t think that it could be down to a duff box? I think there’s many out there (I could be wrong) with signal problems on SD channels. That’s potentially a lot of duff boxes?
The signal quality has improved after second full reset. So I recommend that. A pain to log back into catch up services though.
The thing that worried me was that the Aura doesn’t ask what region I’m in when retuning. I am in South East but can get BBC South news too. I assumed that the Aura is cleverer about that now. Hope I’m not wrong.

Is this a freeview or factory reset? If latter does it keep recordings?
