My last two responses from Humax have basically said
* There has been no hardware change
* I am running the latest software
* It is being investigated
…but I have to say I’m not brimming with confidence at the moment. I can demonstrate I’ve had the problem for over a year, so I think I could make a claim with some chance of success, but hope I don’t have to go down that route….
A couple of pennies to add to this thread…
I have 2 dvb-t2 systems, connected to the same aerial system, with a good signal level; in the Reading area, Hannington transmitter.
One has always been reliable, the other shows symptoms very similar to those already reported here.
Only COM7 is affected.
I’ve not been monitoring it closely; but the dates when I’ve noticed it working/failing seem to match.
i.e. OK early in the year, failing April/May, working for brief periods over the summer, failing Aug-October, working end of October, now failing again.
My good system is a Humax HD Fox T2.
The bad system is not a Humax, but a PC USB stick (August-T210, == Geniatech T220)
This fails under windows and linux – the windows driver is completely closed; the linux one mostly closed, but there is very little raw chipset information to provide any clues as to what part of the synchronisation/demodulation is failing. It just reports – no lock.
From a scan through this thread, I suspect it is only the Hannington transmitter that is at fault.
Whilst people from other areas have posted reports, most seem likely to be unrelated – certainly, all the more consistent reports suggest Hannington.
A few more similar reports here:
https://community.youview.com/youview/topics/hannington-com7-problems
I wonder if all the failing devices use the same chipset?
Only a few devices are mentioned:
Humax 1800t/2000t/DTRT2110 [presumably identical innards],
– this seems to have a Broadcom chipset – BCM3461
August DVB-T210 USB stick,
– tuner NXP TDA18271HD/C2, demodulator Sony CXD2820R
BlackGold BGT3620 DVB-T2 PC receiver card,
– tuner STM STV6110A, demodulator STM STV0900B
(although the BlackGold BGT3602 has a Sony CXD2820R demodulator)
So no, 3 different chipsets, also rules out a software fault – must be transmission problem…
Conclusion:-
Probably a transmitter variation that only affects some chipsets.
Whether this is within the specs. – who knows.
Whether it occurs due to an intentional transmitter change – who knows.
I doubt Humax UK have the ability to provide any technical insight.
It needs someone at the transmitter (or Humax) with a bit of pride to pursue things.

Yes I think myself there is something is defiantly happening to the signal its self as the boxes would not pick them at all. As I have said I have 2 Humax 2000T’s, The new one works fine on COM7 but my old one which is only 6 months which keeps losing COM7 (UHF 32), and yet link them side by side and all the other multiplexes reads the same signal strength on both boxes except on the new one for COM 7 ( UHF 32)it says 89 percent signal and on my older one it says no signal at the moment. But when they are both picking up COM7, they read the same strength. Very strange.
COM7 Back again!
Certainly is… another note to Humax
Yes I noticed it was back last night. I wonder how long it will last this time, maybe a week if we are lucky.
Well, I’d given up; crossed Humax off my Xmas list and everything, but there it is, COM7 is back. It would be interesting to know if anyone has done anything to make it happen. My expectations are low as we have been here before. Will it vanish before the Dr Who special at Xmas…..

Why do you need COM 7 for the Dr Who Xmas special ?
COM7 is not back on my Samsung TV set in London…?
COM7 came back for me as well. Seems to be staying a lot longer than previous periods. It would of course be good to know what has been responsible. I have noted that signal levels across the board seem to have been boosted and I now get improved signal quality on SKY NEWS and that I can also receive BBC London as well as BBC South. Could Hannington have been given some improvements? I’m in the Reading West area.
COM7 channels down again! Exactly the same issue as when I kicked off this topic back in April 2015. Samsung TV ok but Humax not picking up any of the COM7 channels. Reception went down between 23:45 on 23 February and 21:45 on 24 February. In the past numerous posters have speculated that heavy rain in the area may be to blame however we have had no such occurances this time. I’m in the West Reading area (RG30).
Yes, I noticed that it had gone wrong again last night. After 2 months of it working fine, I was hoping whatever it was had been fixed for good.

It’s high pressure (such as we have presently in many parts of England) that can lead to intermittent loss of a MUX.

I always thought that was just an analogue issue e.g. picture ghosting, white noise etc. The digital bods have always been keen to tell us this can’t happen with digital broadcasts?
