John Crispin:

Sony moved True Entertainment and some of their other channels to Local multiplexes, see Digital UK | Channel listings . In your location you should be able to get that along with the local Bristol TV channel on LCN 7 see Coverage Checker - Detailed View . If you haven't got that eithe,r you may not be receiving the Local multiplex on UHF30. Have you got a wideband/Group T orr Group K aerial? If you have an old group C/D aerial this may be why you are not getting it. As long as you don't have Cable or Satellite you can get free help with a new aerial, ring the Freeview Advice line 0808-100-0288 see Important changes to Freeview TV signals | Freeview also see the FAQs on that page in case they may help.

My elderly dad contacted the Freeview helpline due to losing channels, which I let him know about.
He had no problems until the latest changes.

I thought he would have a new aerial fitted as he does not have satellite or cable but one was not fitted.
I told him to phone them again as one should have been fitted.
Seemed to be going round in circles, so in the end he paid for a new aerial himself.
Everything is back as it was.

That is deplorable. This is not the first time that I've heard of cases of people with issues since the Mendip retune not getting the aerial help they should have. I suggest you ring them 0808-100-0288 request/demand if necessary to speak to a manager and ask what they are going to do after failing to comply with their obligations and at the very least get a written admission and apology.

Richard: & All:

Some info I had previously missed which may explain why a number of people are having periodic reception problems of the Local Bristol mux (LBS/LOC1), that is at the last retune when it was moved from UHF51 to 30 the Power (ERP) was reduced from 10kW to 5kW. This certainly won't have helped anyone still using a group C/D aerial (even an enhanced one) which would already be struggling to get any signal on UHF30.


Also note that at the last retune event when COM7 moved to UHF55, the Power (ERP) was reduced from 72kW to 61kW. COM8 & the other main multiplexes were unaffected by power changes.
As many have already noted & commented, the channel and power information on this page may be/is not up-to-date.

I have been having problems with the Mendip transmitter over recent days. I cannot find any aerial or connection problems. I have been fine since the last channel changes in June until just recently.
Incidentally the latest changes are not shown in the 'change over time table' and hard to find online despite them happening. I cannot find any reported problems to explain my problems. My signal levels are about 90% but quality is only high 80s% and I understand one really needs 100% particularly on older equipment. Before I have to get more serious and get the aerial down to check/replace is there anything more general to explain this?

Phil: 90% signal strength is plenty (maybe even too high for some tuners) and 80% quality is hardly anything to worry about. What sort of problems have you been experiencing? Please provide a full postcode so that we can see where you are in relation to the transmitter and your predicted signal strength etc.

There is planned engineering this week at Mendip with "Possible weak signal" which may be the cause of your problems. If you put your postcode into About us | Freeview you can see your predicted reception at your location. As StevensOnln1 says with a full postcode further advice may be provided.

If you use the menus & follow links on the DigitalUK website you can find details and documents relating to the 700Mhz clearance. See also About us | Freeview
Help | Freeview is another place to keep an eye, and loads of other useful information on that site. Unfortunately the operator/owner of this site hasn't updated all the information on various pages here.

Okay, thanks. With all my googling I didn't manage to find the engineering work. What I found was 'no problems'. Nothing shows up here All transmitters with faults and engineering | free and easy or here BBC Transmitter Engineeering information | free and easy for instance. I will explain my setup but really I was looking for just this sort of thing to explain the problems I've suddenly started having over the last few days. I've just been out with the binoculars and the cable and connection to the aerial look as fine as I can tell without getting it down.

I will always be marginal as my postcode is SN6 6EA and I should be using Oxford not Mendip but I want west region. Anyway, I've been doing this since the 80s. I have a 20ft scaffold pole with a Televes DAT45 wideband amplified aerial. My ancient Topfield digibox needs more or less 100% quality. All has remained fine with all the channel changes. Problems over last few days are blocking, freezing, squaking, particularly on weaker channels. My newer TV and Humax box were fine but now the Humax is affected to an extent as well. Hopefully the power will come back up or they will have snookered what I have been doing for over 30 years for this 5G lark. Seems like they are trying to squeeze terrestrial out of existence.

Currently coping by using catchup for unwatchable recordings but not much good for live TV.

Sorry for slow reply. Email me updates doesn't seem to work.
