John: Your signal strength and quality suggest that there is nothing wrong with your signal, it is most likely intermittent interference being picked up. If you have any fly leads are these also good quality double screened coax? Is it possible to match the break-up with any equipment turning on or off, or something being used in the locality such as a lawn mower or power tools? If the interference is being picked up by the aerial amplifying the signal further will not improve matters and could result in too much signal being delivered.

Lynn Gittins (Mrs): As you say switchover is not until September. Could you be more specific about which channels are missing? According to the Digital UK postcode checker you are expected to have poor reception on MuxD due to co-channel interference from Winter Hill. However the other muxes are shown as having good reception at your location. Check that all your cables and connectors are in good condition.

melvyn: The two muxes that you are missing are both transmitted at lower power than the rest, so would be expected to be affected first by any deterioration in the aerial condition, cable/connector fault or obstruction in the signal path. It could be that trees in leaf are currently reducing the level of signal being received by your aerial.

mags: If you are tuned to the Craigkelly transmitter switchover stage 1 took place on 1st June 2011. Did you do a factory reset to clear the channel list and a scan for channels? Stage 2 takes place on 15th June 2011 when you will have to do another first time installation as the remaining muxes will change frequency and mode, and adopt high power working.Although an outdoor aerial is recommended for reliable reception if you have been receiving Freeview on your indoor aerial up to last week it might continue to give satisfactory results on the new frequencies.

Mary: The Digital UK postcode checker predicts excellent reception on Freeview HD from Lichfield at your location. Have you tried to do a manual tune on C34? Make sure you do not have any VCR or Sky boxes nearby with the RF modulator set around C34. You are also predicted to have good reception from The Wrekin on C30-. You would of course need a suitable aerial for this transmitter as The Wrekin is 57 degrees anti-clockwise from Sutton Coldfield at your location.

William Anderson: If the other BBC channels are present and working correctly there is no reason why BBC1/2 should not also be available. Is there a duplicate version in the 800s which works? Did you do a factory reset to clear the channel list before scanning for channels? It is possible that the 2k mode version from Black Hill was found and stored as an alternative region,if so this should no longer be a problem after Black Hill switch-over step 1 on 8th June 2011.

Alan Campbell: If you wish to record material on the video recorders this can only be done by (1) providing an analogue signal via the aerial socket on the VCR if you wish to record via the VCR's tuner or (2) connecting a source such as a Freeview box or Sky box to the scart socket on the VCR and selecting A/V when recording.If you connect the Freeview box of the analogue tv to the VCR via a scart lead you will be able to record the same programme that you are watching on the tv.

john collings: From Chesterfield/Unstone and the Hasland relay Freeview HD begins on 24th August 2011. Additionally for Belmont it is 17th August 2011 and Emley Moor 21st September 2011.

Lee Howard: On 22nd June 2011 when analogue ITV1 is switched off it will be replaced by Mux D3+4 on C41+. Additionally analogue Channel 4 on C47 will be replaced by Mux BBCB, the HD mux which you will receive if you have a suitable HD receiver which supports DVB-T2.

Peter Bird: The problem is not really with the signal strength but poor signal quality. A high gain aerial is not going to stop variation in the strength of signal being received and could result in too much signal on the stronger transmissions. You could try repositioning the aerial to try and find a signal which is more stable and better quality. Moving it a couple of inches to either side as well as raising or lowering the aerial might be all that is required, otherwise try all possible locations around the loft and slightly different bearings towards the transmitter. It is likely that the trees are causing the variations noticed to the signal and rather time consuming trial and error is required to find the best aerial position if you have no signal measuring equipment.
