Retuned this morning and now have COM7 back although with a very weak and unwatchable signal. It's odd if just swapped with another MUX because all channels works fine before. I assume it has lower power than the one it swapped with.

Having real problems with weak signals or no signals at all on COM 7 and COM 8. Never had a problem before until this last week. In post code OX39. Has something changed? Thanks in advance for any advice.

Simon George:
You should be getting really strongf signals on all channels as you are just 3 km away from the transmitter! Check all the aerial connections you can safely reach. Do this by unplugging each plug/socket and then refitting. Then recheck your channels. If that doesn't resolve it, check what the reported signal strengths are for each multiplex, usually shown on the manual tuning page - but DO NOT perform a retune. The ideal strengths are betwee 60% and 85% for all channels. Anything less or more will cause reception problems.

Thank you Mike for the response. I must admit my outside aerial was fitted about 10 years ago but installed by a professional installer. I have had no problems whatsoever with reception since then until the past two weeks. COM 7 & COM 8 show 0% signal strength, where it was 85%-100% always before. All other multiplexs seem fine.
The TV is no more than 1 metre from the aerial wall socket in the lounge. I tried putting a signal booster between the TV and the wall socket and valour I am back to full strength on both COM 7 and COM 8. I don't think we have had any strong winds and the outside aerial seems very secure and not have moved. So i can only conclude that transmitted signal strength has been reduced? Is that a fair conclusion.

Simon George: COM8 hasn't changed frequency at Oxford yet (it moves on 23rd May). Digital UK are reporting the same power levels for COM7&8 so they don't appear to have been reduced. Giving that they are the lowest powered muxes broadcast from Oxford (excluding the local mux) it would suggest that you are starting to see signs of a problem with your aerial system which may require attention at some point.

For the last few days COM6 ARQ-B (Ch.55) from Beckley Oxford has presented no signals. Other viewers locally also have similar problems. A reset and rescan found all other mux's but nothing under COM6 ARQ-B. All other mux's present 99% solid signals. Is this a transmitter fault?

Without a full post code we cannot tell what the reception conditions are like at your location.
However, a signal strength of 99% is far too strong. The ideal is between 60% and 85% and an attenuator could help by reducing the excessive signal strength.

Ch 4+1HD and other channels have no signal, aerial in loft and no problems before this.

Does anybody know whether the MUXes that carry both SD and HD channels can be recorded simultaneously on one tuner or is it one or the other?
I have five tuners on a PC that record Freeview but I have noticed that I have run out of tuners when recording two programmes at the same time on COM7 & COM8.
Thanks

Stephen: A tuner is tuned to the frequency of the multiplex it is receiving.
To record off n multiplexes simultaneously requires n tuners.
To record off com7, com8 and BBC B, the tuners need to be DVB-T2 capable.
It would appear that only two of the five tuners are DVB-T2.
