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 | - 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)

Ive got a similar problem to Dale, I live very near to the Sudbury transmitter co10 9dz, this morning I could not get film 4, so I retuned my digi box, now I realise I can't get film 4, yesterday, itv 4 etc they don't even show up at all. Can you tell me why this is, as yesterday I got all these channels. I realise arqb is changing from channel 50 to 63 but is this the reason for losing the channels and is there a way of getting them back?

I live in Wivenhoe Essex and my rather large aerial is pointed at Sudbury transmitter. Film4, ITV4, Russia Today etc. on multiplex ArqB failed in the early hours of 16/11/11. I powered off/on my Humax Freeview PVR to reboot it, and then re-scanned. Still no Film4 and ITV4 etc. Can anyone advise why I no longer receive ArqB? I have have not had signal problems before 16/11/11.

Russ: Mux ArqB from Sudbury is now transmitted on C63. You will need to do a factory reset to erase the memory of the channels on the old frequency before rescanning, or alternatively delete the channels on Mux ArqB from your channel list then do a manual tune on C63.
