Below are all of jb38's postings, with the most recent are at the bottom of the page.Suzy: With regards to not being able a have a satellite dish because of the trees blocking the signal, have you just been told this as a result of an enquiry? (no matter who you addressed your enquiry to) or was this what you were told by an engineer "after" having carried out a test? as although the image I am looking at is about three years old the angle of obstruction to the satellite position that I see "might" just be able to be cleared if the dish was mounted at near to gutter level.
This being said based on the fact that the dish when mounted on the rear of the building would be facing slightly to the left, and also on the assumption that you reside about the fourth property down from the start of the row, and not right next to the end where the other row adjoins at right angles.
Just really asking out of interest, and by the way I only mentioned Freesat as it is truly free, whereas Sky only is if you can get hold of an old box and have someone install a dish for you.

Colin Howard: The BBC mux on this station will be switching over to high powered operation on September 12th and with the other channels doing likewise on 26th, as things are at present the station has a mixture of powers ranging from 4.8Kw (BBC) down to 1.6Kw (ArqB (11)Yesterday etc) but from 26th all PSB channels will be 100Kw and with the commercials being on 50Kw.
This being the case I would not advise trying to alter anything as nothing would really be achieved, because although reception difficulties aren't exactly unheard of in your area atmospheric conditions could also be playing a part in what you are complaining about plus there is work of an on going nature taking place at the transmitter in preparation for the switch over.

Aubrey Stafford : No, as Belmont's FM radio coverage area is indicated as being limited to the right hand side a line down from Gainsborough to Newark, and of course you are well to the left of this.
Its even a wonder that you can actually receive BBC radio Nottingham, as you are well outside of its coverage area charts.

Dave Lindsay: As far as Nottingham's services are concerned these are on MDS975's web site obtainable via the link provided, where you will see the predicted coverage of BBC radio Nottingham (very bottom map) as well as the independent stations, although only the latter four maps are really of any interest.

This is the link for mb 21's site where Belmont's FM service coverage area is shown.

As far as what Aubrey may, or may not actually be able to receive compared to what is seen as being possible when looking at the transmitters coverage area map always based on standard rules applying with regards to the receiving aerials height etc, no hard and fast rules apply when dealing with this sort of thing and yes it is very possible for a signal to be reaching a position far further than a coverage map would suggest, or of course vice-versa! although the "only" positive way of finding out if anything is possible or not is by conducting an on site test, as otherwise there is no way of knowing.
The only snag though that can crop up should reception of whatever be found as being possible outside of an officially published coverage area is that it might not hold out for very long before the signal suffers from fading problems, so a person must always be prepared to accept the possibility of this happening and take it as one of those things!
As far as the aerial direction is concerned, any FM aerial in common with any other horizontally polarised aerial is automatically directional by nature even if it comprises of a simple dipole, this by the fact of a cone of RF silence existing from the ends of each element whereby maximum pick up is only possible when both elements are facing the signal source flat on.

Suzy: I was beginning to have a sneaking suspicion that the property Google earth was indicating as corresponding to the code provided was possibly inaccurate as the whole row most likely uses the same postcode, however now you have said that you are in the corner position then I fully understand why satellite reception is out of the equation, as that particular position is almost completely shrouded by trees.
Before you give up though there is one final thing you could try and at no cost to yourself provided that you carefully remove it from its packaging without damaging it as it "is" a returnable item, the item in question being a signal booster sold by Argos item number 534 / 4235 and as seen on page 565 of the latest catalogue.
Admittedly I do have my doubts about exactly how effective it will be in your particular situation where fluctuations in the signal level are so commonplace, and I only really suggest trying because its known to be feeding into a box with a stable tuner, i.e: the Humax, but though a device like this can be easily adjusted to keep the signal received running high enough to keep it well away from the lower threshold reception level which should (in theory) help kill off some of the glitches you are experiencing, as boosters "do" serve a purpose albeit that they might well be seen demonized in certain places.

Sam: Out of interest where exactly are you receiving your main signal from? as on the property with a satellite dish mounted on the chimney stack I can see one aerial pointing at Sandy, another at Waltham, and an FM aerial that "appears" to to facing towards Sutton Coldfield.

Dave Lindsay: I just checked the link I provided for MDS975 and see that its not working, and so to save you time searching about just click on - Continue / Site map / Broadcast masts & towers / Transmitter coverage maps / Nottinghamshire.

Glyn: I would try a test by temporarily by-passing the booster and feeding the aerial directly into one of the TV's, checking if that makes any difference.

David: Being located at only 4 miles from the transmitter this problem could be caused by an excessively high signal level being fed into the tuner resulting in it being overloaded, something which will always affect HD reception before SD.
An attenuator placed in line with the boxes aerial input socket should stop this happening "if" indeed that is the cause of the problem, but a simple way to test if you are receiving an excessively high level of signal is to remove the aerial connection and try a set top aerial, if you cannot access one then try a short piece of wire (18" or so) connected into the boxes aerial socket an check if an HD image can be seen.
If this works then purchase an attenuator, this preferably of the variable variety (zero - 20db) as it can be adjusted to suit.

Mr Dennis Talbot: You have to be in the "installers" menu to access these settings, this done by pressing (4) system set up then press in and even flow fashion "0 - 1 - select" and the installers menu should come on.
