To deal with the problem you must clear the channel list completely and then rescan - if your box has it in the menus, please the 'installation menu' to do an initial scan or a reset to factory settings or First Time Installation. You MUST delete the entire existing list of channels. On most boxes this technique can be also be used:

Try this:

1) unplug your Freeview box (or idTV) from the mains;



2) unplug the aerial from the Freeview box by disconnecting the cable from the 'RF in' socket;



3) wait 30 seconds;

4) plug Freeview box (or idTV) mains back in;



5) do a complete scan for channels - it will fail without the aerial. (This may be in the installation or initialization menu, and is distinct from any 'add channels option'). Once this is done your channel line up should be empty;



6) reinsert aerial by reconnecting to the 'RF in' connection;



7) do a complete scan for channels again.



The Freeview channel line-up provided by six "multiplexes" - each of which carry five or more TV channels, radio channels, text services and EPG data. In this diagram each ROW represents a multiplex. If you are still missing a whole multiplex (ie everything on the row) you may need to replace your aerial with a wideband type, purchase a larger aerial or you may have interference from a VCR, games console, Sky Digibox or similar.

Thanks for you detailed reply.
I have a compelling argument as to why my problem is NOT caused by high signal levels.
All Freeview channels carried by "Old" channel numbers 22, 23, 25, 26, 28, 30 and 35 are being received perfectly. This includes channel 30, which in London carries the Full HD channels BBC1, BBC2, ITV, Channel 4, Channel 5, CBBC and TBC (this being a narrow bandwidth H264 commerical gospel channel).
My problem is only with the low power COM7 and COM8 which radiate at 746MHz and 754MHz.
My own theory is that these much higher frequencies are attenuated more by the roof felt and the slates.
Then of course there is the matter of the trees - which change with the season.
I asked you if you could direct me to a website to give me the compass bearing to Crystal Palace.
Such a site existed a year ago - but not now, as far as I can see.
I notice that when I installed the 20 element aerial - it was ordered from CPC around 20th October 2019. With a compass. Having endured some months of BBC Four HD misery on the non-performing 10 element aerial installed may in April or May 2018, I got six months of decent reception.
Until the leaves came out on the trees??
You said in your replay that the Crystal Palace COM 7 and COM 8 signal had been boosted from 40kW to 84 and 81kW. Where did you get that from. I am wondering whether they have actually altered the radiation pattern - pointing it towards Nigel Farage perhaps, rather than rebellious Brixton?
Just to repeat my TV shows now sign of overloading on Freeview 1-105. Or 231-235.
On the other hand it shows severe lack of signal on channels 106,107,109 etc PLUS 93 PBS America+1 (which I watch a lot in the morning - or did until now).
The TV I use has a sort of signal strength indication - but this seems a bit unreliable.
Your comments about my railway viaduct problems - yes is the signal is week all sorts of things happen to the picture (chopped in half, goes green, sound screetches like bats), Currenntly this woud happen on channel 93 - PBS+1, although most of the time totally unusable.
On the other hand all the non-HD channels plus BBC1-Channel5 HD are very stable.
Over to you mate.
PS the aerial currently installed is https://cpc.farnell.com/a…1003
I do have all the previous ones, except the very first Band A on for analogue which I scrapped.
But I don't see a 10 element 1990 wideband installed for analogue channel 5 OR the Band A 10 element aerial I had to install when Freeview went HD (for me 2010), or the 10 element Band T aerial I had to install when Arqiva/OFCOM introduced the wretched COM7 and COM8. I don't see how they will help me now. You are only suggesting that because of you incorrect hypothesis about the signal being too strong.

If you'd read Chris.SE's reply properly, you would have found the new location of that website :

"The bearing to CP hasn't changed, it's still 152 degrees (~SSE) and the DUK/Freeview Detailed Coverage Checker got moved to different cyberspace - not too cleverly - you had to use the boxes on Freeview | All your favourite TV shows, all in one place and all for free & scroll down and selected Detailed view, but they've recently added boxes on Freeview | All your favourite TV shows, all in one place and all for free corporate/platform-management which goes straight to Detailed View.
