Is the transmitter output the same in all directions?

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

Rowland: Although a Google Earth check does certainly suggest that Freesat would be the only way to enjoy glitch free reception because of the tree situation, you should also check to make sure that you are receiving all channels from the same station which could be either Durris (@ 22 miles) or Gartley Moor (@ 11 miles), as both are indicated as being possible (in theory!) at your location, the easy way to tell being whether or not you normally receive ITV3 as if you do then its Durris.
Should this be the case then carry out a "signal condition" check (Panasonics term) whilst on BBC1, because as well as the strength / quality levels being indicated the transmitter channel will also be seen and which should be Ch28, making a note of the levels seen, then using the channel up / down on the remote change the channel to Ch25 (ITV1, Ch4-5 etc) and compare the indications with that on the BBC, giving an update on results.
If though on the other hand you do NOT normally receive ITV3 then you are receiving from Gartley Moor (@ 10 mls) and so carry out exactly the same signal check on BBC where on this occasion Ch58 should be seen, should it be Ch28 then the box has picked up the wrong BBC.
Of course another indication of where you receive from is by looking up at the aerial, because if you receive from Durris the elements of the aerial will be sitting horizontal whereas vertical if its Gartley Moor.

Just noticed a slight anomaly concerning the Durris main transmitter page.It is an all group A transmitter but states that to receive all programmes from Durris a group W wideband aerial positioned horizontally is required to receive Freeview.
Should that read a group A aerial instead,as group W wideband aerials have a poor response on all group A masts in poor/marginal areas.

Mark Fletcher: Yes, you are quite correct on that, as its obviously a remnant from pre-switchover times that Briantist has possibly (dare I say it!) overlooked, or maybe just not got around to correcting, as it dates back to when Durris's channel span used to be from 30 - 52.

Thx JB
I'm getting my tv from Gartley, and the signal strength for the BBC channels is virtually nil.
Any suggestions are most welcome
Thx

Rowland: Well my comments were made based on a visual check of your location and which as was previously mentioned do not look promising for reliable Freeview reception, basically because of the density of the trees that surround you.
That said, the trade reception predictor "does" indicate that good reception is possible in your area, however and as aforementioned, that's in theory as the predictions given do not take account of any local conditions that may apply such as your tree problem.
But though to be able to assess things better maybe you could give an update on the aerial system used as well as the approximate direction its facing as well as the way its mounted, vertically (elements up & down) or horizontally (flat).
By the way Panasonic tuners are excellent, and so the sometimes usual problem of the device being used lacking in sensitivity shouldn't really come into the equation.

Thanks JB - I'll post a pic of the aerial and direction tonight - altho from memory it was pointing towards the NW.
If I see my neighbour I'll ask what their TV reception is like.
Really appreciate your help :)
Thanks

Rowland: Yes, its always the best policy to make local enquiries just to ensure that the problems being experienced aren't being caused by a fault in your own aerial system, the only thing to remember being is to ensure that your neighbours TV is on the same EPG channel as yours and that their aerial is facing the same direction as yours (which being NW is Gartley) and is mounted vertically.
Also in the case of your own TV make sure that any test being done is actually on Gartley's BBC on mux Ch58 and not Ch28 which is Durris, as the latter does indicate (in theory) as providing a better signal, verification of the mux channel being achieved by carrying out a signal condition check and where the mux number will be displayed as well as the strength / quality.
By the way, my only reason for emphasising the checking of the mux channel number is because Freeview equipment starts the scan at channel 21, and with Durris being on Ch28 if an auto tune is carried out your TV could store Ch28 (if receivable) in EPG1's position and place Gartley up in the 800 ranges because of it being on a higher mux channel.
Finally although your aerial is pointing in the wrong direction / mounting angle for Durris it would be interesting to know if anything was being received from Durris, simply done by when on the "signal condition" check screen just using the channel up / down buttons to inch the channel numbers downwards towards Ch28, also try Ch25 (Durris ITV) as well, these instructions being applicable to most Panasonics manufactured in the last four years.

Hi JB
I need to double-check channels and signal strengths on the TV as you suggest.
I'll do that tonight.
The aerial is pointing NW, same direction as my neighbour, and the elements are vertically aligned (for Gartley) but I'll check to see if I can get anything from Durris.
If I'm getting good STV, Ch4 etc from Gartley, shouldn't I be able to get good BBC?
Thx again
