lesley aspin: Apart from the interference detection advice given by Dave Lindsay, on reading your posting a few times I am not sure if you are stating that the ITV channels break up only when viewed via your hard drive recorder but not when viewed via your TV's tuner.
Maybe you could confirm if this is the case or not?

ian from notts / Omhie: My only reason for stating that there was no advantage with purchasing a twin feed Sky+ box if not intending to take out another subscription was that its hard drive would (at times) be running away for no useful purpose but causing the box to consume about 25% or so extra power over that of a standard Sky box, an aspect that would bother some people with any device thats powered up 24/7.
I purposely did not mention anything about the dish, or feed from, because that aspect did not come into the equation, but though if it then I would strongly advise that a twin feed be fitted as this would enable any twin tuner PVR to be used whether it be for Freesat or Sky+ purposes.

alexander taylor: Not unless you change the LNB thats presently fitted and replace it with a dual or quad outlet port type.

edith doris rae: You are one of many who have have made similar complaints since Winter Hills the recent switchover when its BBC transmitter dropped to Ch50, however if you can receive EPG (11)Pick TV OK then your problem could well be rectified by using an SLX brand booster such as sold by Argos (page number 603) item number 534 / 4235 @ £11.99.
If on the other hand you cannot receive (11) Pick TV then you would have to get your aerial upgraded.

Matt: Progress! but of a limited nature, however with reference to the box you mentioned, is anything else seen printed on it such as a type number?, also if by two switches you are really meaning a two position switch, that is a single switch that can slide two ways, A one side / B the other, then this would suggest that the common input to the box cannot feed the signal to both rooms at the same time, although I would certainly find it a bit odd if this was the case as it could indicate that the switch is for some other purpose.
If your TV's are easily moveable then you should temporarily try the main room TV connected into the master bedrooms aerial connection followed by carrying out a rescan on it, OR alternatively (and maybe a better test) check to see if the master bedrooms TV (which has been tuned) still works when connected into the main TV's aerial connection, if you get a "no signal" message or possibly a blank screen, then flick the switch back to its original "B" position and see if this makes any difference, giving an update on results.
It would also be of assistance if you could indicate the number of cables you see going into the box referred to, and whether or not the cables are hard wired into it or are fitted with connectors.

Dave Lindsay: Although its neither here nor there now but the situation is even worse as far as reception is concerned, because using an actual Brackla post code for the terrain checker indicates the signal path is obstructed from roughly 0.75 miles from the destination, although it could even suffer problems from 2.6 miles out should trees exist in that area.

Alec Clarke: With regards to your 4.44pm posting and comments made therein, as you are located at just under 20 miles away from Winter Hill and reside in a ground floor flat then I think it hardly likely that you would be able to receive a signal of any sort from that station using an indoor aerial irrespective of what type it may be, and so a blue screen with a no signal warning is something that's not entirely unexpected therefore should not be considered as being unusual.

Matt: Many thanks for your update / image shack view of the boxes in question as this helped to clarify a few aspects concerning your installation, but though unfortunately adding another mystery!
The black HI Isolation box seen in your picture is (or should be) a relic from the past of about 18 years ago, as this type of device was primarily used back then for satellite selection purposes when Sky was running a parallel analogue and digital service from two different satellite positions, analogue being 19.2 and with digital being 28.2 degrees, and this box enabled a resident of a flat fitted with a dish facility to select the satellite that matched their receiver, hence analogue and digital being seen on your manual.
The mystery I refer to being, that this switch box should have no connection with your Freeview signal unless the system has been modified at some point in time, as its the box on the left hand side that's of more interest, unfortunately though the framing of your picture clipped the view of the cables leaving both boxes, and although the input to the splitter box is seen to be coming from behind the wall I am unable to see if its two output leads disappear upwards or cross over to the black isolation box, maybe you could advise on this.
The other thing I wondered about concerned the TV socket on the wall plate, insomuch is it a standard female coax socket? or is it an "F" male connector? that is a threaded type socket.
Further advice dependant on reply.

hugh williams: Just a point concerning that seen in Dave Lindsay's link, I would strongly recommend the DM log be used in conjunction with a 0-20dB variable gain booster such as the SLX brand sold by Argos @ £11.99 item number 534 / 4235, because this makes an excellent combination for virtually any application whether caravan / boat or even a normal house.
The only one thing I will point out being, is that although the DUK trade predictor indicates excellent reception in the caravan site area from the Llandrindod Wells transmitter, this is somewhat contrary to what would be expected when viewing the info given on both terrain predictors, these indicating that the signal path between the Llandrindod transmitter and the site suffers from a severe level of obstruction, and so I would keep this in mind should you experience any problems as any signal that is received is likely to be mostly through reflection.

Sukh: If the dish is located between the two positions mentioned then the engineer will simply run the two feeds along the wall and either drill a hole through it, or alternatively through the extreme side of the window frame (dependant on construction of) to where the box is installed, as the whole idea is to have the cable run as short as possible.
