K.R.Dale: Heavy thundery type rain can cause problems with satellite reception and especially so if the dish is not perfectly aligned, therefore you should carry out a signal check using the following procedure:
Press "Services" on your Sky remote control and you will see the main menu with "Options" being highlighted.
2:- Select the "Settings" menu using the right arrow button and press select.
3:- Use the left / right arrows to scroll to "Signal" and press select, the grey bars displayed will show you the strength of the signal being received.
Anything indicated should be a minimum of at least 50% for both the strength and quality although the ideal level is 65 -75% with the quality always leading the strength.
Another possible reason for your problem is by water having entered the "F" connector on the dishes LNB.

MikeB: Just a little point about 4G. Although as yet there is no definite proof as to whether or not this potential source of interference is actually playing any part in Clive's problem, but though if it was then what Clive has reported is exactly what would be expected as being the symptoms of a 4G transmitter being tested out, as the swamping effect from a 4g transmitter on the wideband RF input stage of receivers tuner has a much greater effect on the channels received that are nearest to the 4G TX's operating frequency and gradually tapering off on the channels furthest away from it, C49 the BBC channel being exactly that, C29 being excluded from the equation as its only predicted as being able to provide a variable level of reception anyway.
If the aerial being used for Waltham is located in the loft then its much less likely (but not impossible) that a fault has developed where the coax is terminated into the aerials connector box, that said by myself on the assumption that a roof aerial was being referred to, although it would not do any harm to check same purely for elimination purposes.

Heather: With regards to your reference to scanning C52 are you in effect saying that you manually scanned this channel? if you are then I would like you to do it again but pause after entering the channel number into the manual tune box, the reason being that on most Freeview equipment if the channel number is entered without pressing search or scan the signal strength of the channel you are about to scan will be indicated on the level bars.
Further info dependant on outcome of this test.

Heather : Another question that I meant to add being, as most people in your area will be receiving Freeview from the Sandy transmitter have you as yet made any local enquiries to determine if others are being similarly affected as far being able to view (11) Pick TV / (12) Dave / (82) Sky news etc? all of those mentioned being on the ArqA C52 mux.

Andrew Curtis: As you appear to be using Rowridge for your Freeview reception the question would be, if when you had the aerial upgraded did the installer mount it vertically? as the COM channels radiate on 200 Kw on vertical transmissions whereas its only 50 Kw on horizontal.

Andrew Curtis : In addition to that said, the only downside to the aerial being mounted vertically is that you will likely be unable to receive the new additional HD channels on COM7 (C31) on 23.4Kw and eventually COM8 (C37) also on the same power, as well as the new local channel (C29) on 10Kw starting in June 2014, as all three only radiate on horizontal transmissions.

Richard Hibberd : According to the info on this site its not until later on in August of this year.

Tom : And to add to that said by Michael, the reason why you are unable to use the Darvel transmitter can be seen by opening the undermentioned link.

Heather: I feel that COM5 reception having vanishing at around the same time as the tree was chopped down was purely coincidental, that is unless the tree was reflecting COM5 towards your aerial, the complete opposite effect to what tree foliage generally does of blocking a signal.
However, the fact of others located close by experiencing similar problems with their COM5 reception is inclined to point to difficulties caused by seasonal weather related changes to the surface of the terrain, as although you are indicated as having a clear line-of-sight to the Sandy transmitter other factors located at roughly six miles out from you could possibly affect the signal through reflective type problems.
By the way, at 18 miles away from the transmitter I very much doubt that an overly strong signal comes into the equation, although I would still like you to carry out the aforementioned signal test.

TTD: If for any reason the advice given by Dave Lindsay fails to rectify the situation then you should blank out everything stored by carrying out an auto tune without the aerial being connected, then on completion of reconnect the aerial and check that the EPG is blank or alternatively a "no signal" message is seen, then go into the recorders tuning menu / manual tune and enter each of the mux channels used by Craigkelly one at a time starting with C27 (BBC), checking the EPG after each mux channel is scanned to make sure that its been stored correctly before going into the manual tuning menu again and entering the next mux number in line.
Craigkelly's mux numbers being /
27 (BBC1) - 24 (ITV1) - 21 (HD) - 42 (ITV3 etc) - 45 (Pick TV etc) - 39 (4 Music etc) - 33 (New HD)
