Me: As MikeP has fully explained why the procedure mentioned for a log aerial cannot be used where Yagi's are involved then that somewhat saves me from having to, but as far as log types are concerned, the only reason that this can be done on a log is simply because that every element on a log aerial is active and with this being the reason for it being shaped as it is as, the short elements on the front of the aerial catering for the high channels and with the longer elements on the rear for the low, this totally unlike that found in any other aerial which only has one active element positioned immediately in front of the reflector.
The other point about a log aerial and its series of active elements being, that this arrangement results in the aerial having a relatively flat response across the entire band over that of any other type of aerial, and why signal levels measured across a main stations six mux channels when taken using a log aerial always results in a more accurate indication of the true level of the signal being received from each mux by the aerials response not enhancing any part of the band, (short logs being even more accurate) and why standard aerials are unsatisfactory for measuring comparative levels where accuracy is required.
Just purely out of curiosity, when you mention trying tests with your aerial in various orientations I was wondering what type of aerial you are using and where is it installed?

Richard: Although having said that you emptied the box of all programmes was this done using the "factory reset" procedure, or equivalent of such as "default setting" or "first time installation". The only way to avoid receiving the Welsh channels is to use one of the aforementioned followed by carrying out a "manual" scan on each of Winter Hills mux channels, storing the channels found after having scanned each individual mux. Winter Hills channels being / 50 - 59 - 54(HD service) 58 - 49 - 55. By the way an auto-scan does not appear as being possible at your location, as the Llanddona PSB relay station (which you are indicated as being able to receive) uses channels in the same range as Winter Hill. It would also assist if the model number of the box being used was given.

Nick: I will admit to not having noticed your reply at the time, basically because I mostly access UK Free TV by either a twitter link or directly via ukfree.tv/allcomments.php which I find to be more convenient for making quick checks by neither route being dedicated to any particular heading.
But as far as the software version number you supplied is concerned, this was not seen mentioned anywhere in the lists thereby making it impossible to cross check it against anything else, although it could possibly be the very last version issued before the company wound up as all the other software version numbers seen listed ended in Dxxx, not Mxxxx.
On the subject of the intermittent breaks in the sound, if you have verified that the scart cable linking the box to the TV is OK then that fault could still be caused by a software glitch, and especially if the start of the audio down time corresponds to some visual disturbance caused by a glitch in the signal being received, but its a very difficult type of fault to diagnose at distance because it might even be connected to a dry joint on the input to the audio decoder circuitry, this being the type of fault that could only be found out with the aid of an oscilloscope test probe whilst the box was sitting on a test bench, NOT of course that in-depth down to component level faulting such as I am involved with (commercially as well as domestic) is ever carried out on low cost Freeview devices, as a certain number of brand new devices are always kept for guarantee replacement purposes by service depots which is by far a more cost effective way of doing things.
Purely for a test though, the next time that the audio drops out try removing the aerial connector for about five seconds or so before replacing it again and see if the audio returns, because if it does then that can possibly indicate a software issue.

Mandy Lockley: What exactly is meant by 47? and what type or recording device do you have?

emma: If you reside in a block of flats then the obvious question would be if you as yet have checked with any of your neighbours to find out if they are also experiencing problems, because no faults are seen listed on the transmitter engineering page.

Angie: Getting back to the basics, have you as yet made any local enquiries with regards to the standard of reception being experienced by others around your area? as this would at least give you an idea if the problem is widespread or is possibly solely confined to your own installation.
The other thing being, that its essential to find out which transmitter your TV is tuned to, this normally achieved by carrying out a signal strength check whilst viewing a programme as the transmitter channel number is usually given along with the signal strength indications, try this whilst viewing the BBC, Rowridge being Ch24 / Hannington Ch45 / Midhurst Ch55.
It would also be of assistance if you could provide the model number of your Samsung TV, as Samsung in common with LG's etc do not use the same menu system across their ranges.

Angie: Just to clarify on that said, I am looking at it from the point of view that should it be found out that others are also experiencing similar problems to yourself, then it would be somewhat pointless in paying out for another aerial installer to visit your property for the purpose of checking your aerial system out, but though on the other hand if it transpires that no-one else seems to have any complaints about their reception then your difficulties "might" simply be caused by your TV having auto-tuned onto a station whose signal is prone to being received in a somewhat erratic fashion at your location, this being the reason for the signal level / transmitter number tests.
Of course, needless to say that should the latter be found NOT to apply then it certainly is time to seek the assistance of an aerial installer, although before actually doing so I would try and vet (by asking around) whoever you might be thinking on contacting bearing in mind that you were previously told that your aerial was OK.
By the way, if you find anyone who does not have any complaint with their reception, then have a quick glance up at their roof to check on the direction that their aerial is facing.

Pearl: Open the rear cover on your remote control and rotate each of the two batteries by about half a turn just in case they have developed a bad connection, should this action not make any difference to the situation then disconnect you Sky box from the mains supply "after" having left it in standby for about 30 seconds or so beforehand followed by waiting another 30 seconds before reconnecting it again, then once it starts to respond to the remote control allowing it to go through the usual searching for listings procedure.
