Idris Martin: Some receivers give network/region names, these names being the principal coverage areas of the transmitters.

Your difficulty may be caused by the fact that the three COM multiplexes of Stockland and Rowridge are co-channel. You don't have line-of-sight with either stations. The Isle of Purbeck is in your way for Rowridge.

My aerial does not point towards either Rowridge or Stockland Hill that is what is confusing me.

Idris Martin: You cannot use channels 22 / 25 or 28 for the purpose of determining the origin of the signal you are receiving because as Dave Lindsay has said these channel numbers are common to both Rowridge and Stockland Hill, although as DL has also mentioned some receivers indicate network / region names on a signal strength test.

Therefore the only way of finding out the info required is by carrying out a signal strength test on your BBC and ITV channels, Rowridges BBC-C24 / ITV -C27, Stockland Hills BBC-C26 / ITV - C23.

As far as aerial direction is concerned, should your aerial be facing Rowridge then Stockland Hill will be picked up on approximately (as its roughly 30° out) on the reverse of the aerial, and of course vice-versa, but in non line-of-sight situations such as yours signals can sometimes be picked up at different angles to that expected due to reflections from hills etc.

By the way, Rowridge is located @ 47miles / 85°, and with Stockland @ 31miles / 294°, your reception predictions not being particularly good from either station.

Idris Martin : Just in case you are wondering, please ignore the A after the degree angle number, as this is something that has automatically appeared in recent times ever since Briantists site came back on after having been off for a day due to a fault having occurred.

Briantist: Many thanks! much appreciated, as "some" people might possibly interpret this as some technical abbreviation rather than simply being a glitch, it also appearing on pound signs.

jb38: I did notice that I got a receipt from a shop the other day that had the same problem. Everything on the site is supposed to be in UTF-8 UTF-8 - Wikipedia, the free encyclopedia but for some reason it gets into the database OK, but the output isn't being treated as UTF-8.

Hi all
Tried tuning ch 24, no signal then ch 26 strong signal good quality so must be Stockland Hill.
However, my aerial is pointing south west towards Lyme Bay somewhere around 220 degrees so must be locking on to a reflected signal.
Thanks for all the advice.

Idris Martin: Well, although the signal path from both Stockland Hill and Rowridge is obstructed the terrain indicator shows that the severity of the obstruction is far greater in the case of the latter, this somewhat tallying up with your findings insomuch that Stockland's C26 was received but not Rowridges C24, albeit that Rowridge's "vertically" polarised PSB transmissions "are" indicated as providing a superior signal to that from Stockland H.

Of course if (as expected) your aerial is mounted horizontally then this could account for nothing being received.

That said, although it does have to be admitted that anything seen on a reception predictor has to treated with an element of caution, but a point to note is that when carrying out a manual tune test for the purpose of signal assessment its always advisable to enter the "C" number into the box but "not" follow this by immediately pressing search or scan, because on most devices hesitating before pressing same will cause the tuner to act like a proper signal strength meter whereby it will indicate signals down to very low levels underneath that necessary to resolve a picture, but which are ignored during a scan.

By the way, the info seen by opening the undermentioned link (copy and paste into your browser) provides details of the what's expected in your area, the two following being that indicated on the terrain predictor from both the stations in question.

Can anyone check something for me please.

I'm on Rowridge HP and I'm getting the RT channel in 4:3 aspect ration whereas it should be 16:9 and also Film4+1 seems to show16:9 in 14:9 ratio.

I'm using a set top box with my tv and I've tried a backup box and get the same result.

This has been going on since last Thursday and I'm beginning to wonder if my tv might be on the blink.

Both these channels are COM6 so it could be something funny is going on there as I don't have a problem with other channels on that COM so is it my tv or is it them?

Cheers...Colin

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.
