Rover: You need a Freeview HD (DVB-T2) television set, or a Freeview HD box attached to a HDTV.

jb38 and Brian : have sorted out my dad's problem by putting an old splitter into the circuit, in his bedroom, which led to the offending device. MUX D3+4 (CH41) has magically appeared with strength 99% though quality is only 50%ish. The BBCA MUX (CH44) has now gone to 88% quality from <50%. This clearly shows that the signal was too strong for that particular device (though he has no problems on his other 4 Freeview TVs/boxes).
The only downside is that ARQA MUX on CH54 has now 'fallen off the cliff' at 35% quality, and is unwatchable. He assures me that he "doesn't watch any of those rubbish channels anyway : does anyone?" and he can therefore live with that until next June! Oddly, ARQB MUX on CH50, which is supposedly on even lower power than ARQA, is still OK at 50%+ quality.
Thanks for all the help and suggestions.

Just seen Elliot's comment and our problems seem similar. Could it be the proximity of the Rouncefall transmitter? Or are we over amplifying the signal?

shame about the low power multiplexes.

bbc and itv ok and on full.

can get the crappy shopping channels but not some of the ones i actually want like Dave.


the crappy channels should be on the real low power, allowing propper channels priority

well thats how is should be

guess its about greed and making money as usual.

I live in SE Essex and when I had a single high gain aerial installed for digital it was pointed at Bluebell Hill. If a bomb went off in Essex I would not know about it as SE TV is only interested in Kent and Sussex.

When Sudbury switched this week I suddenly found that I was receiving BBC East from the back of the aerial on both my TV and my hard disc recorder. My tv then asked me to retune following which I lost BBC East and got BBC South East back again.

My recorder shows two channels Kent and Sudbury and I can move from BBC Se and BBC E.

Since the BBC reception for my area is between Bluebell Hill, London and Sudbury can it be standardised on Sudbury so that we who live in Essex can actually get local news.

If I get my aerial turned round to Sudbury will it be reliable?

Thanks for your reply Brian. I live in Felixstowe receiving signal from Sudbury. Presumably we have to retune again in November to get a full power signal on SDN,Arq A & Arq B. If so, this is not mentioned in your ' Digital Switchover Process' section above. Please clarify.

The 3 COM multiplxes (SDN, ArqA & ArqB) at Sudbury, currently on UHF channels 49+, 54 and 50+, will not go to full (100kW) power until they change to their final channel allocations (58, 60- and 56) on 27 June 2012.

However, ArqB will move to a temporary channel (63) on 16 November this year but, if you can't receive them now, it's likely you'll have to wait until 27 June 2012.

For Linux users, if you are scanning for channels try using the following in the configuration file for uk-Sudbury

T 634000000 8MHz 2/3 NONE QAM64 8k 1/32 NONE
T 658000000 8MHz 2/3 NONE QAM64 8k 1/32 NONE
T 738000000 8MHz 2/3 NONE QAM64 8k 1/32 NONE
T 698000000 8MHz 2/3 NONE QAM64 8k 1/32 NONE
T 706000000 8MHz 2/3 NONE QAM64 8k 1/32 NONE

MythTV refused to scan properly for ArqA and ArqB so they refused to lock, but once I seeded the scanning process with the above, everything was fine and I could generate my own channels.conf file.
