The symbol shows the location of the Hannington (Hampshire, England) transmitter which serves 470,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

Are there any planned engineering works or unexpected transmitter faults on the Hannington (Hampshire, England) mast?

Gh: Your problem is not the aerial. It's just that you are picking up some signals from the wrong transmitter. As DSO progresses and the power is increased, more distant transmitters become receivable which perhaps were not when you previously tuned your receiver. Without knowing your location, it's difficult to suggest a method to scan channels from only the correct trasnmitter. Manually tuning 40, 41, 43, 44, 45, 46 will give only Hannington channels (until 22nd Feb).

The multiple Transmitter Engineering messages are very confusing as they seem to be mixing up today with yesterday. This is not helpful.

Gh: You're in the 'Guilford Notch', an area where digital signals from Hannington were severely reduced to avoid affecting the analogue transmissions from Guildford, which use the same channels as Hannington's low-power signals.

For you, the difference between the old and new power levels is not 4 dB (2.5x). It's 26 dB (nearly 400x). Many boxes will be 'desensitised' if receiving a loud signal on one channel - it affects adjacent channels most, but nearby channels are also affected.

You will have to wait until 22 February to get ITV/C4/C5 and the other channels listed under Multiplex 2 back. The commercial channels will remain restricted until Guildford switches over: the ArqA multiplex will be derestricted on 4 April and finally SDN and ArqB on 18 April.

It's likely that you had a very big aerial and probably additional amplification to get digital from Hannington at all, before now. It's very likely that you will have too much signal after one of those dates - you will probably need to remove the amplification. Too much signal causes distortion, which causes a lot of errors, often too many to be corrected.

Gh: Unless the aerial is obviously defective it is best to avoid having aerial work done until the full DSO process is complete, which in the case of Hannington ( and coincidentally Crystal Palace) is 18th April 2012. At present you are only predicted to be able to (reliably) receive Mux BBCA, with Mux D3+4 and MuxHD becoming available on 22nd February 2012. The COM muxes will adopt full power working on 4th April (SDN) and 18th April (ArqA and ArqB). If your receiver permits manual tuning try doing a factory reset, then manually insert C43 to see if it will still find and store low power Mux2. Do the same for C40 C41 and C44 before entering C45. Also check that all connectors are in order and not losing any signal through poor contact.

Andy Fraser: "Transmitter Engineering" simply scrapes the BBC's Reception Problems wizard - click 'BBC Reception Test' next to your post. The BBC keep about a week's worth of data but show it as 'today', then 'yesterday', then as a date. "Transmitter Engineering" posts a new comment if the text changes, which means that it will post essentially the same information at least three times: on the date it occurred, the day after it occurred, and two days after.

I don't know if Briantist could clean it up so that "Transmitter Engineering" converted 'today' and 'yesterday' to dates, before comparing. It would be clearer if they were posted as dates. It would also be clearer if each item was on a separate line, rather than all being run together.

It also scrapes Digital UK's Planned Engineering Works page at

Gh and DaveG: After reading Mike's post above I checked and discovered that it is C44 that is released by Guildford on 4th April 2012, so as Mike said Mux ArqA will switch to full power on that date, with SDN and ArqB following on 18th April 2012.

Hi andy my location is frimley green gu16 6lp with signal from hannington. To get hannington before dso you are right i do have a variety of amplification and splitting going on. Can you advise as how to tune manually for the itv,4,5 etc channels. Would an over amplified signal show as either" low or no signal" when i check strength rgs

Your comment please
Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
