Hi,
I had the same problem with the HD channels, when my Humax Freeview box retuned on the 3, September.
You have to do a manual retune, and make changes in the HD Muxes in my case it was C54 and C31 on the Winter Hill Transmitter, look at the frequency and change it to the correct one, also change the DVB-T to DVB-T2 for the HD channels, you will find the signal strength will be good.
The same problem happened again on Wednesday when the Humax updated again.
It seems the Humax box searches the incorrect frequency and DVB-T2 on the HD channels.
Hope this helps.

No difference – I could see the increase in the signal strength on the channels I am receiving, but ch32 stayed firmly at 0% (even though the TV receives it fine.

Not sure what you mean by changing the frequency to the correct one… when I attempt to tune to Ch32, it preselects 562MHz, which seems to be correct. In addition, my TV receives Ch32 quite happily using the same antenna direct and via feedthrough from the Humax.

The puzzling thing is that it worked fine until recently, which is what is making me think it may be a fault on the box.
Have you carefully inspected the aerial cabling looking for badly made joints, kinks or evidence of water ingress. You are assuming that the problem is the box but I think you first need to rule out other possibilities.

Experience suggests that is not correct. For some reason I don’t pretend to understand the Humax boxes are more sensitive to cabling problems than other makes and there is plenty of empirical evidence to support the claim.
Hi,
Looking at the Multiplexes and Channels on the Hannington Transmitter there is no channel 32, so I don’t think you will be able to receive any programs from there on that channel.
Here is the link to the list of channels and frequencies.

It’s just that no one has volunteered to update the site you linked to that 32 does not appear on your reference site.
Try this instead

I guess that demonstrates that you can’t take Wikipedia as a definitive source of data… useful, but not always accurate.
Ch32 is definitely there… as I’ve said, my TV tuner picks it up fine.
Still on my to-do list:
* Check soldering of centre pin in connector
* Check cable quality
..and from Humax support:
* Try another TV (the odds I’d give it for fixing my problem must be close to what I thought – and found – about reformatting the disk).

So what is carried on Channel 32? DigitalUK doesn’t list it either see Link to DigitalUK. care to share the first part of your post code with us?
The original post refers to poor signal on bbc news HD, can you confirm that you receive bbc news HD on your TV with no problem whilst experiencing problems with bbc news HD on the Humax.
Also have you re-tuned the TV, if you haven’t then the TV might be lying to you, re-tune if you haven’t just to be sure.
Have you retuned the Humax with no aerial RF connection between the TV and Humax
I couldn’t imagine reformatting the disk would make any difference either, I’d eat my hat as the saying goes, but I wouldn’t be as dismissive about a different TV; however I’d imagine making sure there’s no aerial/RF connection would suffice, but it’s worth a shot
@damian:
Yep.. TV receives BBC News HD no problem (and I have retuned). The Humax sees 0% signal on ch32, while TV is 100%/100% (signal/quality), both by switching the antenna cable and by feeding through from the Humax.

thanks for the reply, and I’ve no idea, I think most people thought signal drop off or interference, you seem to have covered most bases.
Ideally, I suppose, if possible borrow another Humax, if that works then it’s your original box, if not then it still could be local environment in which case test it at a neighbour’s if possible.
I still find it strange that your TV shows 100%/100% on com7 for signal/quality on what should be a lower powered channel. I think you’ve already confirmed that you’ve had the Humax connected directly to the aerial on its own with absolutely no other devices or feeds connected in any form to the aerial.
It looks like you’ve exhausted most sensible options and you need to take the box elsewhere or get another box in to test.
Let us know how you get on
Well, I haven’t yet had time to check the cable condition and soldering, but here’s a twist. The weather was much better today and for some reason I thought I’d give manual retune another go for Ch32 (atmospherics being one consideration for poor reception).
Bingo! Now the signal level is as expected (strength about 70%, quality 100%) and I can pick up the expected channels. So – two possibilities, I think.
1) Atmospherics… possible, I suppose
2) Cabling – if there were ingress of water that could cause some problems but would it dry out so quickly?
thanks for the feedback,
can’t imagine water ingress as we’ve had the driest September for a long time and the problem appeared a couple of weeks ago.
I’d still suspect interference; however the main thing is that the box isn’t faulty, but without knowing the cause it leaves an uneasy feeling that it could return at any point.
If it were my setup, I’d check the levels on the TV again and then again for the TV and Humax with the attenuator attached. Whilst it’s working again it’s an ideal opportunity to see if you can break com7. If you can’t then it might even have been a transmitter problem
