Dave Lindsay:
Thank you for your response. I apologise for asking the same thing twice but I lost my link at the end of my email and did know for sure it had been sent.
Can you tell me please how long the scheduled work is expected.
Regards Ian Jones

Ian Jones: I'm going on the information provided by Digital UK and therefore cannot say further. The Digital UK site gives information on a weekly basis. Exact times of low power and outages can't be given as these things are done as and when they are needed during the works for technical and safety reasons.

Hi
I note that on this WEB site there are now no reported current problems are shown for the Mendip Transmitter. Since the 28th we have not recieved any BBC services whereas every other channel has a strong and perfect signal. We appreciate there were works upto last week. We have reset the TV without ariel connection and subsequently with. Still no BBC - can you please advise.

Ian Jones: You should be getting avery good signal on all channels. Best guess - somethings up with your aerial system. Normally, BBC channels are the strongest, but if you've got a loose connection, frayed wire, etc, then that mux might be the one that suffers.

Hi Mike
Thanks for that but all is in order.
I have found that my friend at no:5 BS14 9AQ (I'm at 32) suffered the same problem, the total loss of all BBC channels, as did some of our neighbours. My friend actually had his ariel turned to pick up the Ilchester Crescent signal where he could get BBC but not a good signal - this has always been our problem hence Mendip.
The ariel fitter that turned my friends ariel said that there had been a lot of work on the O2 mobile mast at the junction of our road and the WEllS RD at the same time as we experienced problems.
Can you please advise and what action will be taken.
Many thanks
Ian Jones

Do you have an aerial amplifier at all?
If work on the O2 mast has meant adding 4g in the 800MHz band (haven't checked) then there may be some overload happening, you might need a filter. However I'd had expected other mux channels to be knocked out as well.
Are you talking about the HD channels or the SD ones?

Hi Chris
Yes we do have an ariel amplifier.
Do not understand 'other mux channels'.
As to HD or SD channels all I can tell you is that when I do a 'First Time Installation' I end up wit 73 channels instead of 100+. The only thing I can honestly tell you is that the is no BBC channels at all. I have the basic Freeview service.
You mention 'adding 4G in the 800MHz band (haven't checked)' - do I read this as you will check?
