andyboy: I suspect your aerial is not pointing at Sudbury, but another transmitter. If you want Freeview HD today, you need to ensure you are using the correct trasmitter.

Does anyone know what the re-tune event is for on 16th November? And will it affect me if I am getting my signal from Rouncefall rather than from Sudbury direct?
| link to this comment |
lisa: No, it will not affect Rouncefall broadcasts.
Sudbury's retune is because one of the commercial multiplexes is moving frequency: ArqB which carries Film4, ITV4, Yesterday and others.

lisa: It's very hard to say that you're 'on' Sudbury or Rouncefall, both have quite a large area of influence and the overlap area is large. If you do get ArqB on C50 now - the channels that Dave listed - you will lose them on Wednesday and will have to retune to get them back. If you don't get them now, you *might* get them by retuning on Wednesday. However, it remains on lower power, so you're still not predicted to get them (if you're still at the address you were before).

lisa: As for *why* it's moving frequency: it's to give up C50 for Tacolneston to use from next week. The planned final home for this multiplex is C56, but this can't be used yet because Dover is still using it. There is another retune on 27 June 2012, the same day as stage 2 of Dover's switchover, when Sudbury's commercial multiplexes will all move to their final channels and power levels.

Remember that the temporary move of ArqB from UHF 50 to UHF 63 on 16-11-11 will also involve a doubling of its (very low) power from 1.1kW to 2.2kW.
That may make it available to more viewers but the shift up the band may also take it past the reception capabilitries of some aerials.

Damn! I wish I hadn't written that second paragraph.
Guess what's happened to my terrestrial reception.

All seems to have gone pear-shaped with the move from Ch 50 to Ch 63. I have always had all channels here with quality at least 6 out of 10, even when all were on low power before switch-over, but today ARQB on Ch 63 is giving me Quality 1 out of 10. My Panasonic PVR just about copes, my LG TV tunes in but picture is totally broken up, and my cheapo Tesco TV won't tune in that Mux.
I had a wide-band aerial installed 3 years ago, so this should not be an out-of-band aerial problem. Removed signal amp back in July. Yesterday all ARQB (Ch 50) channels were fine with quality 9 out of 10.
Anyone got any ideas?

Dale: See:
Single frequency interference | ukfree.tv - independent free digital TV advice
Could it be your Panasonic PVR (or some other box) that has a modulator in (thus sending out a signal on an RF channel)?
If one device works, then I would be inclined to take the others to the same aerial outlet and connect them up and see if they will pick up the same channels. When doing so, I wouldn't have it looped through the PVR, just incase it is this that is causing the problem. (DN31NJ)
