Like Rick, I too have been disappointed about the lack of HD channels broadcasting from Kilvey Hill and have attempted for years to learn what organisation is responsible for deciding whether Kilvey will broadcast COM7 and COM8 to write to them to enquire, however, I have never been able to find out. Does anyone know? Having just read your reply StevensOnln1 if all COM7 and 8 are closing in a few years what will happen to HD channels?

John B: COM7 & COM8 are commercial multiplexes operated by Arqiva, using spare transmitter equipment that was taken out of service at the time of the digital switchover. This allows it to operate at a low cost (very little new equipment needed) and allowed additional Freeview capacity to be made available to broadcasters at a significantly lower cost than capacity on the existing (and nearly full) COM4/5/6 multiplexes. Adding additional transmitters such as Kilvey Hill would require additional equipment (therefore more cost) and would only add a small percentage of households to the coverage area - COM7/8 would have to be added to more than double the number of transmitters to reach the same level of coverage as COM4/5/6 (80 transmitter to reach 90% of UK households) which would push the cost up significantly and probably wouldn't have attracted some of the smaller channels such as FreeSports, PBS America, Forces TV etc to join Freeview. None of the broadcasters have announced what will happen to their channels on COM7/8 when these temporary multiplexes close.

Jo: True Entertainment is not broadcast from any transmitters in Wales. Depending on where you are (please provide a full postcode) you may be able to receive it from a transmitter in England.

Hi there,
In the last few months I have lost Drama & Quest channels from the Kilvey Hill transmitter.
I see on your above table that this is the COM4/SDN MUX and that changes were made on the 17th Oct. 2018. (I seem to have also lost the other channels you list on this MUX)
Does this mean I should buy a Wideband aerial to restore these channels.
My postcode is SA67 8NT and my Group A aerial is mounted on roof.
Kind Regards,
Graham Richards

Graham Richards: All multiplexes broadcast from Kilvey Hill are well within the frequency range that should be receivable on an existing Group A aerial. Have you tried manual tuning on UHF channel 25?

Graham Richards:

Looking at the expected reception at your location using the Digital UK Coverage Cgecker, at Coverage Checker - Detailed View it suggests that reception of the BBCA and D3&4 multiplexes is likely to be poor and variable whilst that of the BBCB HD multiplex should be good. However, the signals from the Preseli transmitter are better and probably more reliable, it does however mean a change of aerial to either a Group B type or a wideband one. Preseli is only 25km from you on a bearing of 5 degrees, whilst Kilvey Hill is 54km distant. So I would suggest you consider having your aerial chaned and aimed at the Preseli transmitter.

Thanks for the info. I have now tried manual tuning but still no good. I will have to see if there is a problem on the roof and if not invest in a new aerial. Drama & Quest channels were always a bit 'iffy' especially in the summer.

Thanks for the info Mike. Yes I know Prescelli is quite close to me but unfortunately nobody in my locality is pointing that way. When I first moved here in the mid 70's I remember trying for the Prescelli transmitter without succss.
I will look on the roof for obvious cable problems with the wiring to the booster boxes etc but if nothing is obvious I will have to invest in a new aerial. The signal from Kilvey is generally good enough for most of the channels but marginal on Quest & Drama.
