I have strange problem with COM7 107 BBC News HD, 108 Al Jazeera Eng HD, 109 Channel 4+1 HD, 110 4seven HD, 113 RT HD. I have newish 55" Samsung TV. I had to have my aerial put in the loft. Problem I have which started occuring around Wimbeldon time and still persists - not sure if they added new channels, I don't remember having RT HD or Jazeera HD, and even some childrens new HD channels. Is this causing issues by cramming so much on the transmitter? Or is it because I have loft aerial - which doesn't explain why they work perfectly in the evening.

In the day these channels DO NOT work = no signal. In the evening they DO work. I'm in Warrington using what I assume is Winterhill based on my aerial direction. Channels with issues: 107 BBC News HD, 108 Al Jazeera Eng HD, 109 Channel 4+1 HD, 110 4seven HD, 113 RT HD,.

Any ideas why I have this symptom?

Tony Morrissey: All of the channels you mentioned have been present for a few years, they certainly haven't been added recently. Loss/breakup of signal cannot be cause by having too many channels on the same multiplex. The most likely explanation is that there is some piece of electrical equipment (could be in your own home or a near neighbour) which is operating during the daytime and causing interference.

If you provide your postcode, we can see from Digital UK - Coverage checker what sort of signal you should be getting at your location.

Thanks for the info Chris that link was great website. I already new my coverage was good in Warrington. However looking at that link today 1/8/18 they have a retune event occurring for Winter Hill. I've wiped re-tuned many times over past month. I have made no retunes today - but those channels had same problem yesterday and started working later in the evening. However today "retune day" without me retuning - all is working @18:30 1/8/18 without issue. Maybe they've made adjustments? Or maybe it's just erratic symptom on my end. Either way if I think on I'll report back if it continues to consistently work without issue.

tony morrissey:

Sometimes, after a set has been retuned several times, its memory map is a bit "disjointed". It's often best to do a factory reset/do a retune with the aerial unplugged to clear the memory of all channels and then do a new tune with the aerial plugged back in. However if you are now getting satisfactory reception on all muxes, I would leave well alone until/if further issues arise ;)

Update - Errors in the current Freeview EIT:

There are 954 events containing invalid character codes in the EIT off BBCA.

There are 43 events containing invalid character codes in the EIT off BBCB.

There are 954 - 43 = 911 events containing grammatical errors the EIT off BBCB, caused by the omission of the intended character codes.

An example event:

Freesat - this is what the event should look like:

BBC Radio 1, Thu 23 Aug 04:00 - 06:33: Adele Roberts
Adele's got you, Early Morning Crew! Guess the lyric for a shout out in Whose Rhyme Is It Anyway?'

Here, Freesat is correctly using 0x2018 and 0x2019 for left and right single quotes respectively.

This site probably won't represent those characters, so here is what it should look like using just the ASCII apostrophe:

BBC Radio 1, Thu 23 Aug 04:00 - 06:33: Adele Roberts
Adele's got you, Early Morning Crew! Guess the lyric for a shout out in 'Whose Rhyme Is It Anyway?'

The Freesat EIT text is Huffman coded and the decoded output is in utf8, so, for example, the left single quote is 3 bytes [11100010 10000000 10011000] which translates to Unicode 2018.

See UTF-8 - Wikipedia

The invalid character codes on Freeview are the least significant bytes of the correct codes.

It's interesting that the missing top byte is always 0x20 - the code for a space. Are Freeview running something that strips extraneous spaces from the input data?

EIT off BBCA - invalid character codes 0x18, represented by {L'} and 0x19, represented by {R'}, for the left and right single quotes respectively:

700 BBC Radio 1, Thu 23 Aug 04:00 - 06:33: Adele Roberts
Adele{R'}s got you, Early Morning Crew! Guess the lyric for a shout out in {L'}Whose Rhyme Is It Anyway?{R'}

EIT off BBCB - missing apostrophe and quotes - therefore grammatical errors:

700 BBC Radio 1, Thu 23 Aug 04:00 - 06:33: Adele Roberts
Adeles got you, Early Morning Crew! Guess the lyric for a shout out in Whose Rhyme Is It Anyway?

An example from the 43 events common to BBCA and BBCB EITs, which contain invalid character codes:

094 PBS America, Sat 25 Aug 18:10 - 19:10: Plane Resurrection - Series 2
B25 Mitchell: The plane of choice for the {L'}Doolittle Raid{R'} needs a major winter overhaul to be ready for the air show season, but this little lady proves to be something of a diva. (S2 Ep5)

Note: All 43 events are on DVB-T2 multiplexes.

The example event above was replaced by this:

700 BBC Radio 1, Thu 23 Aug 04:00 - 06:33: Adele Roberts
Adele{R'}s got you with a Summer Mix, Early Morning Crew! She hits play on a Drake versus Kanye mix

No matter, nearly all Adele Roberts event descriptions start with "Adele{R'}s got you", so demonstrate a bad code.

Here's a new one - with a duff code in the title:

105 Channel 5 HD, Thu 30 Aug 04:00 - 04:45: Now That{R'}s Funny

105 Channel 5 HD, Thu 30 Aug 04:00 - 04:45: Now That's Funny

As always, Freesat get it right with code 2019 = single right quote, and Freeview get it wrong with code 19 = garbage.

Because Channel 5 HD is on a DVB-T2 multiplex, and all EIT text for services on DVB-T2 multiplexes is Huffman coded, this error is present regardless of which multiplex the EIT came from.

Another thing that needs reporting is the appearance of the FTA content management descriptor on DVB-T.

Most events on these radio channels have FTACMDs:

BBC 6 Music
BBC Asian Net.
BBC Radio 1
BBC Radio 2
BBC Radio 3

This set is also the set that have duff codes.

The FTACMD for those events has a value of F6 which according to ETSI EN 300 468 means:

Scrambling shall be applied where applicable for content protection.
Redistribution over the Internet is not allowed with the following exception: Redistribution over the Internet within a managed domain is enabled after a specified long (possibly indefinite) period of time.
The content revocation process shall be applied.

Just wondered what peoples signal level of Com 7 was like compared to Com 8?, I am in a fringe area of Glossop, and currently cant get any signal on Com 7 at all but can get Com 8 fine, and according to this site Com 7 is meant to be higher power, strange.
