We have recently started suffering from a lot of macroblocking and even total loss of reception on the BBC SD mux only. This is from the Mendip transmitter? Have they reduced the signal level?
postcode is GL12 8NN
Aerial is on the roof

I live in Bristol, 48 and 49 from Mendip have always been poor, unusable signal levels, but have now completely disappeared, zero signal strength on both. I have to use a Skybox with expired card to get BBC regular channels on freesat.

I live in BS1 - central Bristol, and recently, with no obvious reasoning I have started getting very poor signals from Channel 4, 4+1, film4, 5, and now ITV and similar channels as well. BBC seems to be one of the only fine channels. What on earth is going on?

Oliver Grills: Are you sure that your receiver isn't tuned to the wrong transmitter?
From your location Bristol Ilchester Crescent and Mendip are roughly inline with one another, albeit that the former is vertically polarised and the latter horizontally so.
For ITV, Channel 4, Channel 4+1 etc Mendip is on C54 and Ilchester Crescent on C44. For Film4 Mendip is on C52 and Ilchester Crescent C39. The tuned channel number is usually given on the signal strength screen.

My Mendips reception has totally disappeared. Several retunes have resulted in no signal at all. It was a 10 signal.
Pointing the ariel at Salisbury gets the usual poor picture..
Has the aerial group changed and thus I need a new aerial?

John Spillett: The William Hepburn's tropospheric ducting forecast chart currently shows that ducting could be affecting South Wales and Southwest England, with Devon and the Bristol Channel areas showing as the most likely to have TV and VHF radio reception affected by out of area signals.

See Tropospheric DX Modes for a discussion on Tropospheric Ducting and what causes it. It's a bit technical but worth wading though.

I seem to have a problem with my TV aerial. The aerial socket seems to have a loose connection. It's one of those sockets that's built into the house and I suspect that the cable connecting it to the aerial is the probably the original cable put in when the house was built in 1972. I think that the cable needs to be changed. In contrast, from ground level, the aerial seems to be in quite good condition and may be OK. What should I expect to pay a contractor to service my aerial system and change whatever is needed? How much more would a DAB aerial cost? What's the best way to find a reputable aerial fitter?
