I have now lost all signal can you tell me what the problem might be?
The problem could be one of:
- the aerial has been moved or damaged;
- the cables or connectors that connect the digibox to the aerial are damaged;
- the digibox has broken.
If you have a "spare" digibox you use this to test the aerial connection. Can you still watch analogue TV OK?

David : You could try a filter that cuts of frequencies below UHF channel 38 or 39, however you would loose the local TV mux from Black Hill on UHF channel 30 (all other muxes are on UHF channel 40 or higher). Does your TV have a manual tuning function? If it does, you could manually tune the wanted multiplex frequencies from Black Hill.

As StevensOnln1 says, a manual tune may be the best way of dealing with this.
Here are the correct UHF multiplex channels for Black Hill in the order PSB1-3, COMs4-7, Local -
They are C46, C43, C40, C41, C44, C47, C55, C30 (C meaning UHF channel).
Whereas Craigkelly's are C27, C24, C21, C29, C31, C37, C55, C32.
Probably the best way of dealing with this would be to unplug the aerial and do a full automatic tune which should clear all previous tuning as no channel;s should be found. Then plug the aerial back in and do a manual tune on Black Hills channels.
Filters are unlikely the best way to deal with this, they have "insertion" loss which may weaken the wanted signals. If you provide a full postcode we may be able to see why you are getting Craigkelly's signals instead of the stronger ones from Black Hill. There may be another "trick" you could use if manual tuning is not an option.

HI Chris,Stevens
Thanks for your comments.
I can see that filtering out channels below 37 would also attenuate some of the desired channels from the Blackhill transmitter.
The TV does have a manual tuning so this is probably the solution.
The postcode is G768ET.any further comments welcome.
Regards
David

David :
Unless you have checked in your tuning section that your set is/was indeed tuned to some of Craigkelly's channels, IMHO your aerial "installer" may be just hazarding a guess! Whilst Craigkelly is probably within the reception beamwidth of your aerial (bearing is roughly NE, whereas Black Hill is approx ENE, 74 degrees) it's considerably lower power and around 75km or so away, and neither Freeview nor the BBC predict any reception from it - that doesn't mean you won't get any, but the chances have to be much smaller.
You shouldn't have any problems with signals from Black Hill except COM7 (C55) and the Local mux (C30) could be a bit iffy, predicted to be "variable".
There is a relay local to you 1km away at Netherton Brae (almost in direct line to Black Hill) but very very low power and the aerial needs to be vertical polarisation, whereas it's horizontal polarisation for Black Hill (& Craigkelly). It could still be possible to pick up some signal from it, but it's only the 3 PSB multiplexes on UHF C23, C26 & C29.
Which channels/programmes were you actually having a problem with? Btw, do you have your own aerial or is it shared?
Looking at the situation overall, I think, as you can do a manual tune, it's not worth messing around with any other things (eg. possible use of attenuators whilst tuning). It could be that last time you did an automatic tune, some of Black Hill's multiplexes were off-air for maintenance OR your set retuned automatically when it had no signals. If it has that function then turn it off/disable it, it's more trouble than it's worth. The number of times you actually need to retune are minimal.

Loss of signal from whitehawk hill transmitter in Brighton

Ray major: Whitehawk Hill is currently listed for engineering work with possible service interruptions, according to Freeview's website. There is no indication of how long it will list, but often it is only for a few hours at a time, with work usually being completed by the evening.
Do not attempt to retune whilst the work is taking place. If you have retuned already you may need to retune again once the work is completed to restore missing channels.

Win: There has been a fire at the Bilsdale transmitter this afternoon, resulting in a loss of signal for all TV and radio services. See my post on the Bilsdale page for more information.
