R.Porteous: Basically nothing has changed as far as the transmission side of the equation is concerned, but though, as the line of sight from Ellon (dependant on exact location) to the Durris transmitter is seen to be obstructed in two separate places, i.e: at approximately 3 & 7 miles, then changes to atmospheric conditions as well as to the surface of the terrain can cause signal levels to change with reception in this type of situation, and it "might" just be that yours has dropped to under that necessary to resolve a picture.

Go into your TV's tuning menu and select manual tune then enter Durris's BBC1 Ch28 but stop at this point, because on most devices if any signal is being received (no matter how low) the strength / quality level of the signal will be shown.

By the way, if both of your aerials operate completely independently of each other? then this in effect excludes the possibility of your installation being defective.

Further assistance dependant on outcome of test.

Hello, would be grateful for some advice. My home is near Boyndlie (AB43 7DY) at 100m elevation. The Rosehearty relay is 3 miles away and I can pick it up with a Telecam 2000 indoor aerial on a bookcase. I need to move the aerial into the loft (5m height) which is just a crawl space. I've measured up and could fit a mini log periodic such as a Labgear LPCT or perhaps a Labgear LAB350T tri-boom. Does anyone have a view if either would work for Durris or Rosehearty. Would be great to get Durris. I realise its a bit of a vague question but would appreciate any views. Thanks

Neil: Although the Durris transmitter is indicated on DUK's reception predictor as being possible to receive in your location, reception is not necessarily guaranteed to be glitch free, as a terrain check indicates that a line-of-sight obstruction to the signal path from Durris exists at around 4 miles or so. This being the case, I would suggest that your best policy would be to try a test by temporarily installing the Telecam aerial in the loft and couple it into any TV with a manual tuning facility.

The procedure being to select manual tune on the TV followed by entering the Durris transmitters BBC1 on Mux C28 into the box but "not" pressing scan, because on most (but not all) Freeview equipment, if any signal is being received then no matter how low it might be, the level of will be indicated in the strength / quality bars.

You can also use this procedure as a signal indicator whilst you are experimenting with aerial positions, as it turns the tuner into a form of low cost signal meter.

Further advice can be given dependant on the outcome of the test.

Neil: In addition to that said. If the test using the Telecam aerial does not pick up the slightest trace of a signal from the Durris transmitter located @ 45miles away on a bearing of 191 degrees, then reception from Durris is not possible with an aerial in the loft no matter what type it might be, because although set top aerials are never really recommended for the reception of DTT signals because of their vulnerability to movement (human) within the room they are located in, they can be very effective when used at height.

However, if you do manage to receive a reasonably stable signal from Durris, "stable" referring in particular to quality, then the log aerial used in conjunction with a variable gain booster should meet your requirements.

By the way, a variable gain booster ideal for use in conjunction with a Log (or any) aerial is the SLX brand device sold by Argos: item number 107 / 1533.

PS: Its easy to determine if anyone in your area (albeit sparsely populated) is receiving signals from Durris by having a look up at their aerial, as any aerial used for reception from Durris will be mounted horizontally, whereby the Rosehearty relay transmits on vertical polarity.

First of all a very big thank you for the excellent advice. Very much appreciated and saved me money! The advice on manual tuning saved me the cost of a cheap meter and using the Telecam to detect signals from alternative transmitters saved me the cost of a suck-it-and-see aerial.

I threaded some WF100 satellite cable up into the loft, ran it straight to the telly through a hole in the wall rather than use a wallplate, and put coax connectors each end. I then plugged in the Telecam (without amplifier) and positioned it in the general direction of Rosehearty with vertical orientation. Result. Good signal quality and middling strength. I then changed it to horizontal and tried to pick up first Durris and then Rumster. Nothing at all. So the terrain maps were correct, no line of sight to Durris or Rumster. So I will purchase a small log periodic (probably the 400mm Labgear LPCT and mount it on a small loft mast. I'm sure that will give a much better signal than the telecam. Many thanks once again.

Neil: You certainly "are" a fast mover! as I wouldn't have expected you to have tried what was suggested quite as fast as this. But though, if you failed to obtain the slightest trace of a signal from the Durris 100Kw transmitter on Mux C28, then the situation with regards to the channels really desired, i.e: COM4 -C23 / COM5 - C26 / COM6 - C29 is likely to be a non starter, as these channels only radiate on 50Kw.

Based on the reception obtained using your Telecam aerial, its almost guaranteed that the Labgear LPCT will be perfect for your requirements even although its only 400mm in length, Log aerials having always been my preferred choice of an aerial for use in most situations, and indeed three of them being used in my own installation (two amplified) to enable reception from three separate stations, albeit admittedly this mainly being for test purposes.

Thanks for the update!

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.
