Mendip transmitter - January 11th retune required

If you use the Mendip transmitter (but not the relays) for your digital television reception, you will need to retune - again - on January 11th.

published on UK Free TV

At the moment, viewers using the Mendip transmitter are unable to subscribe to Sky Sports 1 and 2 via BT Vision and/or Top Up TV - see BT Vision, TUTV, Sky Sports 1+2 and the Mendip transmitter -

To deal with this, on 11th January 2011, Multiplex D will change from being broadcast on C59+ in 16QAM mode, and switch to be the "normal" Arqiva B multiplex (10kW ERP) on C67 in 64QAM mode.

It will stay there until it moves to C52 on 28 September 2011. This date also sees Multiplex COM4/SDN move from C62+ to C48 and COM5/ARQA move from C56+ to C56.

In summary - if you use Mendip - even if you don't use Sky Sports, you must retune again on 11th January 2011.

When you retune - use a "first time installation" or do 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

Note: This event is not part of the digital switchover process, and is not being managed by Digital UK, but by Arqiva and ITV.

If you have any questions, please call ITV on 0844 881 4150.

The chnnels are all fine with these, however the sony tv I have in my bedroom has lostvariouse chnnels, including channel 12,18,21 and a few others. The channel numbers were listed on the screen but not tuned but, when I retuned the tv, they have completely vanished, any ideas please.

Last year Humax sighed a contract with Sky to receive Sky thru there HD-FOX T2 box. I think this was going to be thru the Internet. Gone very quite on this contract.

Brian, Have done this and done a manual retune as otherwise we pick up the welsh channels and BBC West goes onto 800. I have checked the signal strenght wish is excellent. I had problems after the original retune and had to wait for an upgrade from Humax for my PVRto download. 6 months !!! So suppose will have to wait again if this is the problem. If I switch the machine off at the mains and then back on again the sub titles reappear

Dave Spencer: Thanks! It worked
I've had problems with my Humax and the Mendip Transmitter. I could only get itv, ch4 & 5 through the 800 channels (coming from wales, and I'm i Chippenham!!) Retunes as advised made no difference. Quality of advice from professionals here is pretty lame!

I did as Dave Spencer suggested. on a second retune, kept the arial out till just under half way through the retune and popped it back in during the retune. I now have all my channels on all the right places with no signal problems at all.

Firstly, thanks for an excellent website.
I am on the fringe of both the Mendip & Wenvoe transmitters. I have a roof mounted horizontal 12 element Yagi pointed at Mendip and a loft mounted horizontal 8 element Yagi pointing at Wenvoe. Both feeds are combined and fed into an Antiference splitter box feeding four outlets in various rooms in the house.

I sat down yesterday and went through a full scan of all channels. The channels shown on this site to be broadcasting at 100kw on both transmitters are showing full strength / good quality. Channels 56 & 62 from Mendip, although broadcasting at 10kw and showing lower strength and quality are watchable without problems. Channel 67 from Mendip, broadcasting at 10kw, is showing low strength quality and is unwatchable most of the time. Channels 42,45 and 49 from Wenvoe, although transmtting at 50kw are showing low strength / quality and are unwatchable (This I suspect is due to the small aerial mounted inside the loft).

My questions are therefore this.

1. Can I expect the Mendip channels that are currently being transmitted at less than 100kw to be increased to 100kw when switchover completes in all adjoining areas?
2. Is the fact that some of the Mendip 10kw channels (C56,C62) are OK, whilst C67 is not, because C67 is at the top of the frequency band? If so, should I grit my teeth and wait for it to move to C52 in September or would a better aerial resolve this?
3. Can I expect the Wenvoe channels that are currently being transmitted at 50kw to be increased to 100kw when switchover is complete?
