The symbol shows the location of the Midhurst (West Sussex, England) transmitter which serves 94,000 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 Midhurst (West Sussex, England) mast?

Tom,Horsham: Not receiving C50 does not necessarily contradict KMJ,Derby as he did not say that you would be able to receive. It is, according to information from the powers that be, a fact that C50 is now up to its full final power of 10kW.
Before switchover, Midhurst's lowest channel was 55. I therefore wonder if your aerial system has a filter in place that is preventing C50 from going through it from the Midhurst aerial.
Below 55, there is only C50, so perhaps there is a filter that cuts off signals somewhere between the two.

Andrew.Difficult to say without a full postcode or nearby location as such.The answer is no to the question you asked depending on which main transmitter or relay mast you are on.

Mark Fletcher, postcode is BN44 3TB, transmitter is Midhurst. SDN signal is weak, sometimes we get it, sometimes we don't. ArqA and ArqB we can't get at all. Assuming this is due to their lower power. Would like to know if there are plans to increase the power and when? Would very much like to receive all the channels.

Andrew,Steyning.Yes that is correct in what you have now specified relating to the lower signal strength DSO commecial multiplexes on Midhurst main transmitter you are currently experiencing with.
Currently SDN on 10kw,ArqA on 5kw and ArqB on 1kw,SDN multiplex is now already broadcasting on its final 10kw power output,while ArqA and ArqB ultimately will increase in power to 10kw apiece also their final power output around possibly Wednesday 27 June 2012 when the last three remaining South East England main transmitters,Heathfield (DSO1 Wednesday 30 May 2012,DSO2 completed Wednesday 13 June 2012),Bluebell Hill and Dover (DSO1 Wednesday 13 June 2012,DSO2 completed Wednesday 27 June 2012) complete both their analogue TV/lower powered pre-digital TV switch off/and their post higher powered digital TV switch on takes effect.
You may have to wait until around Wednesday 27 June 2012 for the commercial multiplexes to increase strength to 10kw altogether their final outputs to receive all the channels you are hopefully waiting for.

Andrew: The power of the COMs from Midhurst will not increase in power.
I fear that your problem isn't so much low power signal from Midhurst, but the Steyning relay transmitter which is on King's Barn Lane adjacent to Broadfield Stables.
The transmitter doesn't broadcast its signal omnidirectionally. Whilst the powers that be won't release the radiation pattern under FOI, examination of photographs of the transmit antennas on the mast leads me to believe that it beams its signal in your general direction, as well as that of Steyning. (The radiation pattern is the plot of how much signal it throws out in each direction.) Whilst it is vertically polarised, at such close proximity it's probably not surprising that a horizontal aerial picks it up to a degree.
Steyning transmitter broadcasts only the Public Service (PSB) channels (i.e. it doesn't carry the COMs you're having difficulty with). But the three channels that it uses are the same as those used by Midhurst for its COMs. A similar situation exists in Horndean and in some other cases elsewhere that are near to low power relays like Steyning. This is obviously one of the reasons that Midhurst's COMs are restricted in power with respect to the PSBs.
In October of this year the three channels used by Steyning will change and one of Midhurst's COMs will do as well. At this time some of Midhurst's services will cease being co-channel with Steyning's.
I see that there are quite a few aerials on your road that appear to be on Crystal Palace. This may give you the Commercial channels.
I sympathise that you may have a decision to make; to do nothing now and wait until October or spend money making changes to your aerial(s) so as to receive the COMs from another transmitter until October.

Hi,
I am not recieving com6 channels such as Film4, ITV4 etc. I tried the reset procedure and still no help.
I use a community antenna and I have brand new TV and I know a friend of mine who has a similar tv and can view these channels. So it is not a problem with the TV.
Please advice.
Thank you,

Deep: It might be worth noting that COM6 is on channel 50 from Midhurst. It is the lowest channel number that is used now.
Before switchover, the lowest one was 55 which is now the second lowest.
Perhaps your aerial system is filtered so as to only allow channels or a range of channels used by the designated transmitter. If this is the case, then it will need adjustment in order to let the COM6 signal through.

@Dave, Thank you ! Is there a way to find out if the aerial system is filtering and if so who should I contact to adjust this in the aerial?
Thanks again for your help.
