Rescanned successfully on 3 Freeview TVs, 2 digiboxes serving analogue TVs and 1 Elgato EyeTV for the iMac. Each receiving all channels, all MUXes, all programmes from wideband loft aerials.


We have a DVR (Digihome DTR0207 twin terrestrial tuner) which worked just fine (well, with the occasional freeze or pixelllation consistent with a loft aerial pre-switchover) until 3-6 months ago. We considered replacing this box but decided to await the mid-April 'final' re-scan and associated power-boost.

After today's re-scan, ALL that it will find is MuxC on C40.

This PVR is fed by an aerial which does not go through a booster/splitter. (I have tried it fed from the other loft aerial, through the booster/splitter same performance.) The RF out from the PVR feeds a Freeview TV which re-scanned successfully today, finding all channels, all MUXes, all programmes.

Any suggestions?

Your table above shows Aquiva B on channel 48 from Wed 13th April 2011. It seems that it is on CH67 from today 13th. I beleive it is at 64QAM because yesterday I could receive the old BBC MUX B on CH67, today I cannot receive anything. Its seems they are parking ARQ B on 67 for a while according to

TheWoodman: I would think replacing the DTR0207 with a new Freeview+ or Freeview+HD box is a good option.

Briantist: for my postcode MK130QG gives a very useful table of MUXES / Frequencies for current status and next FOUR changes requiring a retune. Sandy Heath DSO is so complex!

At present only channels avialble are those on PSB1/2/3.

Colin and Briantist: According to Digital UK C67 will be used by Mux ArqB (8k mode)until 14th September (when it changes to C48). C67 is then used by MuxC (2k mode) from 14th September till 23rd November 2011. MuxC/ArqA then changes to C52 in 8k mode.

Thanks: Lee and KMJ, that confirms why I can't rx that mux. CH 67 was borderline on MUX B before DSO, for some reason it is below the threshold now. I got a few broken images earlier, confirming it is there, seems I will have to wait until later in the year for that mux.I have a high power external aerial but is locally blocked by trees just coming into leaf.
