The current signal prediction for my location near Insch, Aberdeenshire currently shows best reception to be from Gartly Moor transmitter. But previous predictions during 2011 showed the best signal to be from Durris transmitter and I had aligned my arial to Durris.
Why has this changed?
Should I be realigning my arial to Gartly Moor?
Would I receive the same range of channels from Gartly Moor?

On a separate subject - the "Terrain" version of the signal map for my area is not available on my computer (I am using Internet Explorer 8). What enhancement to my computer systems are necessary to enable the "Terrain" map to be displayed?

Jim Bell: Don't read too much into coverage predictors; use them as a guide only.

The fact that you have had two different results suggests that the method of calculation is different or has changed.

Digital UK Tradeview predictor puts Gartley Moor a little behind Durris.

However, Durris is a full service transmitter and Gartley only carries Public Service (PSB) multiplexes/channels, so you will probably wish to receive from Durris, even "if" relatively speaking, it does not provide as good a reception as Gartley at your location.

Durris uses Group A channels and Gartley uses C/D ones, so if you have a Group aerial, then it will be less sensitive for one.

The three Commercial (COM) channels from Durris (those that Gartley doesn't transmit) are at half transmission power to its PSBs. The COMs also use a less robust transmission mode (so that they can fit in more services). What this means is that if you are going to have difficulty picking up any channels from Durris, then it is likely to be the COMs.

Jim Bell: This plot to Durris shows that your line of sight is blocked roughly between 5 and 6 miles away:

Why are you asking about re-aligning your aerial anyway?

Thanks for your response.
I have no serious problems (that I am aware of) with reception from Durris so have no reason to re-align my arial. My queries arose after being advised that Durris would have a weaker signal this week - I happened to see the signal prediction map and found it had changed since I had last looked at it.

I'm not sure if anyone will be able to answer this as even I have no idea what's going on, but here goes anyway:

our Freeview reception tends to work about 90% of the time but I believe that is due to problems with the aerial when it decides to break up the picture. We are probably going to get that fixed at some point. The query however is can anyone tell me why certain Sky channels are interrupting Freeview reception?

downstairs we have the usual Sky box (the normal one, not HD) connected to the TV as usual and Freeview downstairs has more channels than the TV's upstairs. However when you switch the TV on to one of the UKTV channels (such as Watch, Alibi or Gold) BBC1 and BBC2's Freeview connection goes, plus it will normally reduce the reception of the other muxes and won't come back until you switch it to a Sky channel that the TV deems "suitable". It does happen with quite a few of the shopping channels as well but I really have no idea what is causing it

I don't particularly think it's anything to do with Freeview itself so it's probably something to do with the Sky box. Anyone seen this before and can maybe offer a solution?

RUMSTER FOREST TRANSMITTER & GARTLEY MOOR TRANSMITTER.
My Freeview signal comes from either of these two but mainly RUMSTER FOREST - can someone confirm that the signal has been strangled from RUMSTER FOREST in recent days? If not there is a major problem with break up and the obvious boxy pictures - I have had my antenna checked but both my Freeview HD receiver is simply freezing on ITV3 and on my built in Freeview on my Philips Plasma there is no signal whatever.
My antenna has the needed yagi's and it also has a masthead amp to try and bring the proper signal in without any luck.
I have also tried all the obvious, such as re-tune, factory re-sets, turning off things like auto updates, back lighting etc...Help! please.

William Davidson.If you leave a full postcode preferably or a nearby location as such,we may be able to distribute further advice and assistance to you.
The full postcode is to ascertain the reception possibilities in your locality as what you specified there could be another mast which possibly could impede the signals you receive at your abode.

why does the balgownie transmitter not offer a full service like the durris transmitter does. this is so unfair to many people. and should be rectified as soon as possible. why should certain areas be deprived, it simply isn't right.

w.stewart: The Commercial broadcasters that don't transmit from Balgownie are purely for profit. They choose where to site their transmitters and do so in order to provide the best return for themselves. Any such decision therefore does not take into account the "fairness" on those viewers whom they do not wish to serve.

The Commercial broadcasters achieve a 90% coverage from 81 of the largest transmitters largest by viewer population and for them to transmit from the 1,000 or so small "filler-in" transmitters, including Balgownie, would roughly double their transmission costs whilst only providing them with an additional 8.5% of the population.

They show adverts to viewers which they wish to aquire at lowest possible cost this being the simple law of capitalism. For this reason, it's not surprising that they don't wish to double their cost of transmission in order to increase their number of viewers by about 10%.

My Panasonic Freeview LCD TV has good reception for stv, 4, 5 etc, but I had to do a factory reset and scan to get the bbc channels.
The bbc channels were then found but are very pixelly and not watchable - presumably why the original autoscan didn't assign them a channel number.
I'm not sure the landlady will allow a satellite dish, does this sound like a problem that could be fixed with boosters or a new aerial?
We're at AB51 5HR and surrounded by trees.
It's ironic that the channels you need a licence for I can't actually watch :)
Hope someone can help
Thanks

Your comment please
Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
