Dave: This is, or was, as it should on again by now, the reason for your inability to receive 5 live today.

Radio 5 Live - Planned work at the Moorside Edge Transmitter

Due to essential engineering work, we have had to temporarily shut down one of our major transmitters in the north of England, making 909AM unavailable to 5 live listeners in that area. To keep listening to 5 live, you can still find us on DAB digital radio, Digital television or online via bbc.co.uk/5live. Service will be restored after the work is completed, which is expected to be around 7pm. We're sorry for any disruption to your listening that this may cause.

Tim H: You should carry out a test on the outlet socket used by your main TV by temporarily connecting the bedroom TV into it and selecting channel 60.

If the bedroom TV has a signal checking facility? check the strength of C60 whilst its still connected into the bedroom outlet, and use this for comparisons purposes against the indication obtained when its connected into the main sets outlet.

Of course, if your main TV is moveable? you could always try the test in reverse.

Stephen: Regarding the latter query in your posting, yes! its entirely possible for one device to play up whilst another connected into the same aerial system doesn't, the reason for being purely down to the design of the tuner, as wide variations can be found across a range of tuners as far as their sensitivity and stability levels are concerned.

On the subject of 4G, transmissions from this source can affect freeview reception by swamping / desensitising the tuner, the effect of making it insensitive to picking up freeview transmissions, however judging by what you have said, I more inclined to think that the tuner used by the PC has the edge on the ones fitted into your TV and freeview box.

If you wish to find out if any 4G transmitter equipment is operating (or being tested) in your area, a company set up for this purpose called AT800 are the people to ask, details available via the link.

Frank: If you are referring to a standard Sky box? then use the undermentioned procedure.

Press SERVICES on your remote control
Select (4) :- SYSTEM SET UP
Select (4) :- ADD CHANNELS

Then enter the following /

FREQUENCY :- Punch in 10.964
POLARISATION :- H
SYMBOL RATE :- 22.0
FEC :- 5/6
followed by selecting and pressing on FIND CHANNELS.

When the new channels are found, highlight FIVE by pressing the
Yellow button, not forgetting to press store after the channel has been selected

Ch5 can be viewed by selecting SERVICES then OTHER CHANNELS, this accessing the menu where manually tuned channels are stored.

tim: Selecting and clicking on "digitaluk trade" under your posting indicates that your area is served by the Hannington transmitter

Coverage Checker - Detailed View

Maybe you could explain as far as exactly what is not working?

Walt: According to that seen on digitaluk's coverage checker it is, and although numerous reception dead spots exist along the beam angle of this transmitter, your particular location would appear well to the right of the one nearest to your area.

If you have recently retuned your Freeview TV or box and no signal was indicated on C57, this does not necessarily mean that the signal isn't there, as it could be, but is being received at a level just under that necessary to resolve a picture.

The way to test if it is or not, is by going into your Freeview devices "manual" tuning menu and entering C57, but stopping at this point and waiting to see if anything shows up on the signal strength / quality indicator bar, as on most Freeview devices this procedure results in the tuner acting in a similar fashion to a signal meter, i.e: no threshold cut off levels involved.

Further advice dependant on outcome of test.

TimH: The content of your update is inclined to suggest that the problem is really being caused by the signal fed into your TV being a tad over powerful for "its" HD tuner to cope with, this resulting in instability in same, the reason for highlighting "its", being that the overload level tuners are able to cope with varies from one brand of set to another, HD tuners being far more critical to this sort of thing over SD, although SD can also be affected if any multiplex channel is being received at a slightly stronger signal level than the others.

If your signal is really strong, purely for a test, you might be able to resolve a picture of sorts by connecting a short length (4 feet or so) of wire into the TV's aerial socket, or better still, if you could access a set top aerial, otherwise you have no option other than to purchase a signal attenuator (around £2-4) to insert in line with the TV's aerial input connection, a value of around 6dB or so might possibly suffice.

By the way, you should also check the set up menu of the TV in question to make sure that it isnt of the variety that incorporates an internal booster facility, if it does, switch it off.

Walt: Yes, but this is where the difference between theory and practice comes into the equation, as indeed as stated in the qualifications mentioned under the map.

If you carried out the manual check exactly as stated, that is "not" pressing tune or search after having entered C57 (doing so triggers reception threshold levels) and nothing was indicated, then the signal doesn't appear exist in your area, this possibly being due to the signal from the very low powered 1Kw transmitter being blocked by the numerous trees seen in your area, whereas the six main muxes (100Kw each) and with Com7 and Com8 rated at 25Kw/22Kw respectively can.

Walt : In addition to that said, although you may have drawn a blank as far as reception from C57 is concerned, but though I was wondering if you can you receive any signal from Winter Hills 2Kw Mux on C56?, and if you do what programme comes up on EPG 8?

rob : Thanks for the update, pleased to know that you have succeeded in overcoming the problem.

However, I do have to say, that as far as your old mast head amplifier as well as the age of is concerned, they either work or they don't, never partially unless through internal corrosion caused by water ingress, and your success is more likely to be attributable to the 4G filter incorporated within the new amplifier rather than anything else.

Although you cant go wrong by updating / replacing your old masthead amp.
