UK TV frequencies map - channel C68 (850.0MHz)

My Free View box which is built into my new Toshiba LCD Tv does not appear to recieve any of the ITV channels ITV 3 etc etc.

I have other freeview boxes in the house which pick up the relevent channels.?????

Any Advice would be great. I live in Brackley and think my local antenna is the Oxford base. Assumption taken from your website.

Cheers

You probably don't have a wideband aerial, when you need one - or you might need a more suitable aerial if the signal is weak, for example if it is located in a loft. Goto the My Freeview reception page to find out more for your location - just enter your postcode to find out.

I have been having problems over the past few days in recieveing Five, Radio's 1,2,3 & 4 with my Digilogic DSTB1000 box.
These have been OK but were variable in quality so I retuned the box & now I have lost all of the above channels (plus some others). I live in Stoke (ST4 8DJ) and a few years ago (due to some objectioanl building work) our whole estate was fitted with new ariels pointing at Winter Hill (instead of the local Fenton transmitter). The Digital quality has been ok until this recent problem.
The problem appears to be with "Multiplex A - D3" on channel 68 from Winter Hill.
Is there a problem with the output from Winter Hill or is it a problem with my Digilogic Box?
Any comments would be appreciated.

H Smith: The problem may be local interference from a VCR, games console or Sky Digibox. If you have one of these, turn them all off to see if they are the cause of the problem.
If not, check your cables and connectors are in good order.

Hi Briantist, thanks for your comments...
No VCR connected to this setup, only a DVD recorder (which is off most of the time), our games machine is attached to the "older" tv which uses a loft mounted aerial on a totally separate aerial circuit and no Sky Digibox.
My confusion on this is that the system has been working (albeit poorly at times) until recently.
I will try retuning the box either tomorrow or the day after in case it is a problem with WinterHill output power/engineering work or perhaps even atmospheric conditions.
All cables have been in & out to see if this was the problem. No change, MUX A still not working properly. All other channels appear OK.
UHF channels 56, 60, 63 66 & 67 all come through @ 100% signal strenth. Manually tuning into CUHF Channel 68 results in 0 (!) signal strength.
Any other thoughts?

Retuning my digi-box on Monday morning cleared all of the problems with the loss of channels on MUX A.
The information regarding channel strength on the WinterHill transmitter was not very clear.
All OK for now.

H Smith: I'm pleased it's working, let us know if you have any more problems.

I'm in manchester and I've got three freeview boxes in the house. I've re-scanned two of them and lost the channel 5 mux completely and have really bad reception on mux 2. My third freeview still has channel 5 mux and I don't want to retune it incase I lose it too.

Is this likely to be due to the work on the winter hill transmitter at the moment, or something else do you think? (map)

David E Haworth: It's possible, there is work listed at the top of the page in red ... Freeview on Winter Hill TV transmitter | ukfree.tv - independent digital television and switchover advice, since 2002

Well, the work has finished and I still have my problem. basically any freeview box that is already tuned into the 5 mux works fine, but I can't retune them and get it. it's almost like the transmitter isn't advertising that it has the C5 mux, if that makes sense. if a freeview box knows the channel is there, it can show it. Anyone else experiencing this? I've got it with 2 decoders, but the other two (not retuned) can show those channels fine.

Cheers

David Haworth: It could be a local interference issue with that one box. Please have a look at Single frequency interference | ukfree.tv - independent digital television and switchover advice, since 2002

Briantist,
I don't think it is. I've put another (already tuned) freeview decoder on the same aerial connection (as in unplugged from the goodmans, and plugged into the new one) and it showed the missing channels fine.
still not sure what the problem is.

i have two freeviw TV in the house. One with a built -in system. This worked very well until recently but I have now lost C68. I have tried numerous times to reinstal without success. The tv maufacture say it is not a fault with the set but e low signal power from the Belmont. If that is the case why has it suddenly gone down. The other TV with a separte freeview box still recieves C6 (map)

Les Adams: Interesting. Do both systems use the same aerial?

I am a CCTV installer working in the Woldingham/Cateham area of Surrey. I am frquently asked by customers to insert the CCTV signals into their household aerial system by using a CCTV RF Modulator in the aerial line. One problem I often encounter is interference from adjacent TV channels, so my question is; which channel should I use in order to encounter the least inteference/crosstalk from other channels being broadcast in this part of Surrey? My initial thought is to use Ch 36/37/38, as they are not allocated to broadcast use, but will eventual use of these cahnnels by other media compromise the use of an RF Modulator using these frequencies to carry CCTV signals?

Nigel Williamson: C37 is used for analogue five; C36 is used for Radar and C38 for Radio Astronomy. You can find a list of free channels at any given address by putting the postcode into the box at the top left of the page.

Thank You, this information was most helpful, and really rapid too!! If I need any more info I will certainly come and ask you!

Best Regards (map)

Nigel Williamson: Always happy to help.

I have a problem with Mux A on C68. I get all channels except for Five and Vigin on the DTT tuner of my DVD Recorder. Rescanning on the internal tuners of my TV's and stand alone set top boxes does not produce the same problem. The DVD Recorder is a Phillips DVDR7250H. I understand there's been an over air update for Phillips tuner recently. I wonder if that caused some problems.

Glenn Davies: C68 is often a "default" channel for a device with an "RF output", can you check that your DVD Recorder has not chosen to use this channel for RF output?

There is no RF output connected that's set to interfere with C68. With the recent re-tune the channels missing are ITV3, Virgin1 and Quest. No other channels in Mux A are missing as I'm sure they would be if there was RF interference from a loop through.

Glenn: How about doing this My Freeview box has no EPG, is blank on FIVE, ITV3, ITV4, ITV2+1, has no sound or the channel line up is wrong | ukfree.tv - independent digital TV + switchover advice, since 2002 ?

What channel numbers are BBC1 and BBC2 on now at winterhill. Not even sure I can add them manually. BTW the list of boxes that don't work does not inlude computer capture cards.

keith marriott: Ah, for the computer, please see Switch over and PC-based systems | ukfree.tv - independent digital TV + switchover advice, since 2002 - PSB 1 is on C62- (801.8MHz) the frequencies are listed at Freeview on Winter Hill TV transmitter | ukfree.tv - independent digital TV + switchover advice, since 2002

did glen ever fix his issue. i have had the same box. too costly to forget about and replace. i have no bbc channels and no itv2. i have been coping without for age and thought the recent move of house may fix it but nothing and now i want to record the grand prix on sunday!!!

joanne: It's hard to say without knowing where you are.

all my channels on all 3 of my freeview boxes on frquency 850mhz have just stopped working today, espn, fiver, five usa, itv3, virgin. all my boxes are in different rooms. the signal strength has been stuck rigid on 35%. surely this must be a fault with the transmitter rather than something my end ?

piete: It is very unlikley to be a fault with the transmitter, much more likley Single frequency interference | ukfree.tv - independent free digital TV advice - but also please see Freeview reception has changed? | ukfree.tv - independent free digital TV advice .

since the fire at Beckley we have not been able to receive any of the channels transmitted on 068, before the fire we had crystal clear faultless reception, we live in Carterton and the charts show we are in a strong signal area. Can you please advise why we can not receive these channels? We have a built in freeview receiver in our Sony TV, the signal for the normal channels has also dropped significantly to the point we have had to consider subscribing to cable or sky. We have considered a new aerial but as we had no problem before the fire we do not want to waste money unecesarily. Can you please advise.

Mr D Shorten: Yes, it probably is the fire, see Oxford transmitter - service restricted until end of September 2010. | ukfree.tv - independent free digital TV advice - but it might not be, so please see Single frequency interference | ukfree.tv - independent free digital TV advice before you do anything else.

I receive analogue from The Wrekin transmitter, but no digital signal!

However i do seem to get digital from Brierley Hill transmitter even though i only have a group A aerial!

However the two mulitplexes on channel 66 and 68 are virtually non existant (except if it rains then 100 per cent signal quality and strength. Is this because the channels are too high for the signal range? (map)

Stuart Harris: You won't get any signal from Brierley Hill at all with a group A aerial, see Aerial group performance | ukfree.tv - independent free digital TV advice .

The performance you are getting is quite consistant with a wideband aerial. Freeview on Brierley Hill TV transmitter | ukfree.tv - independent free digital TV advice .

Stuart Harris: To receive signals correctly from Brierley Hill you will of course need the aerial mounted for vertical polarisation.Using a wideband or group C/D aerial should give good results but if extra gain is required on C68 use a group E.
