Just back from 3 months in OZ. Humax EPG is telling me BBC4 HD has moved. Retuned, twice, auto tuning, but does not find it. Where has it gone? How do I get it back? In North London. TV, Samsung, rescan doesn’t find it either. Thnak you
Channel moved multiplex in mid January.
Now broadcast on Com 8 which is not available to all and transmits on much lower power then others muxes.
Do you know which transmitter you receive signal from?
Edit: posted before I saw Barry’s post.
As you have actioned an auto-retune it should still be on 106.
There is a possibility that your aerial does not receive the new underlying frequency well enough, or if a communal aerial it has not been setup for UHF 35. I’m presuming you are receiving your channels from Crystal Place
On your Humax if you go to the manual retune what ‘Quality’ and what ‘Strength’ does it show for UHF channel 35?
MENU > Settings > Installation (default password 0000) > Manual Search > use right button > select 35 from the list > select left button > for transmission select “DVB-T2”.
For crystal place the underlying frequency is changing again on 21st March.
Thanks for responses. Channel 35 has strength and quality 0, on both DVB-T and DVB-T2 transmission. Ditto Channel 33. Yes, Crystal Palace is the source – yet this data coverage checker says all is perfect in N5 http://www.digitaluk.co.uk/coveragechecker/main/display/detailed/N5+2BE/84/0
Do you suggest waiting until 21st March? A pity because BBC4 HD is one of the few channnels I watch.

The site does not know your particular aerial setup so presumes you have a standard aerial installed correctly at 10 metres high for Crystal Palace.

Unfortunately the situation may get slightly more complicated as the older aerial installations for Crystal Place never took into account that someday the frequency of the broadcasts may change as much as they are going to change for BBC FOUR HD on 21st March.
In my view its worth spending a bit of time now trying to understand what has happened rather than wait until 21st March when it could get more complicated.

Thanks for the additional 33 information.
Channel 33 itself has not changed. If you were receiving BBC FOUR HD 4 months ago then when looking at the quality and strength now for channel 33 and DVB-T2 it should still register a number bigger than zero.
Sorry to ask but when you looked at the signal/quality for 33 are you sure that you were looking at DVB-T2 and not DVB-T on the screen?
Also do you have a communal aerial or an aerial just for your home?
Oddly Channel 794 saids BBC4 HD against it. See pictures. Now after yet another retune it doesn’t.
Aerial is properly installed, shared between 3 flats, less than 5 years ago. BBC4 HD has been available. Haven’t asked other neighbours if they are receiving it in HD. There have been some storms while away, so maybe there’s a problem with aerial, but it finds all other HD channels.
Did look at DVB-T2.
Very puzzling.
Sorry – wouldn’t let me attach pictures.
I’ve lost BBC FOUR HD (Channel 106) on my Humax Fox T2 despite numerous retunes and resets. The odd thing is that my Sony TV can receive channel 106, but only after I removed the aerial signal splitter/booster, so the signal must be there. The Humax box just can’t receive it whatever I do.
Just to add, I am in the London region.
The MUX’s which carry BBC FOUR HD and others have moved to UHF channels 55 and 56 (on March 21st). These channels are outside the range of a group A aerial, which is probably what you have. Also many landlords ignored the advice sent to them about the change so many people in flats etc have this problem.
The latest changes are causing problem for many people in London:

I don’t have a Humax Freeview box (I have Humax Freesat box, so no problems!) but I did try re-tuning my Samsung 4K TV and got the same as you. The test case is the missing BBC Four HD but there are other channels missing.
Could that splitter/booster be blocking the new channels on 55 (COM7) and 56 (COM8)???
My problems seem to be down to a communal aerial!

My problems seem to be down to a communal aerial!
The most likely issue is the one identified above. For a very long time Crystal Palace has used frequencies within the reach of a group A aerial.
Look at the aerial group graphs at this link.
http://aerialsandtv.com/tvaerialtests.html#AerialGroups
Along the bottom is the UHF spectrum channels 21 to 68.
The gain curve for a group A is shown in Red. Look at the point where the red curve hits the zero gain bottom axis (about halfway between UHF channels 37 and 48. The two Multiplexes that carry the extra HD multiplexes have moved to UHF channels 55 and 56. At these frequencies a Group A is about as useless as a chocolate teapot
Now look at the black Wideband gain curve.
Splitter and Boosters are designed to handle all the UHF channels 21-68 pretty much the same. There may be a built in filter in the communal installation that blocks the higher frequencies.
In the end it’s down to whoever is paid to provide the communal TV services to sort it out.
Reading this thread with the same problem of no bbc4 HD in London and no signal strength on ch35 since Mar 21St.Yes I have an old aerial, however i have all channels on my newer Toshiba TV that is connected to the same aerial! How can the aerial be the problem of it works for newer receiver?

It can’t. However COM 8 isn’t on CH 35 anymore. Your TV may have retuned automatically. Have you tried a retune on your HD-FOX-T2 ?
On the 21st March
COM 7 moved to UHF 55 and COM 8 to UHF 56.
Your aerial clearly isn’t a group A so hopefully a retune will fix.
I wouldn’t worry too much London viewers, you are in good company with most of the Midlands and North West, who experienced this issue a couple of weeks before yourselves.
I myself have had to have a new aerial fitted – Log36. Now able to watch the 19 or so missing channels again. Mind you COM 7 and 8 are operating on reduced power so some people may still struggle even with an new aerial.
Look on the bright side – the government will be making zillions more pounds by selling off the vacated spectrum to the mobile operators for 5G services. You don’t begrudge spending a few quid on an aerial if it makes the government and mobile operators richer, or do you……….
