Lenny R: All the channels you've mentioned are 'Freeview'. What you've lost is some of the other mux's. You havn't given a postcode, so there is a not a lot anyone can say, part from its likely to be a problem with your aerial system - perhaps a frayed cable, etc. Its kind of working, but its only getting the stronest muxes. Could even just be your aerial lead is loose!

Along with the new "That's Solent" on Channel 8 I also cannot receive QVC Extra on Channel 57 and "Pop" on Channel 125 on my unamplified wideband loft aerial. Cannot the power of this multiplex be slightly increased so as to rectify this problem in my area in Portsmouth?

Chatton Transmitter
TV reception from Chatton stopped last week then restarted briefly then stopped again until last night (11/12/14) when all worked OK again and is still working this AM. How can I check if Chatton transmitter is working OK and is the information reliable? My experience with internet supplies is they are always working even when there is no signal, hope Chatton is not the same.

m.whitbrook: On the basis that you are 5 miles from the transmitter, and with clear line-of-sight, too high a signal level would seem the most likely possibility!
Freeview signals: too much of a good thing is bad for you

I have lost Dave Pick and Sky News. I have done a factory reset and te-scanned. Nothing. Sony KDL37EX403 all other TV's are receiving fine

Jane Morris: Its sounds like your lost Mux Com 5 - Rowridge (Isle Of Wight, England) Full Freeview transmitter .
Could be a number of things, but its likely that your aerial has a problem. Have a look at the aerial lead - if its loose or not working properly, then that migth explain the problem. Replace it and see if eveerything is OK.

Jane Morris: You are missing COM5 multiplex which is on UHF channel 22 from Rowridge.
If the set has manual tuning then go to it and enter/select UHF channel 22 and wait don't press the button to scan/add channels/OK. The TV may act as a signal meter, giving you an idea as to strength and quality.
If you haven't already done so then having your aerial vertically polarised (elements up/down) rather than horizontally polarised (elements flat) will allow you to receive the more powerful COMs.
This will forfeit reception of COM7 (BBC Four HD, BBC News HD etc) as it is only horizontally polarised. However, looking at the terrain plot with Butser Hill in the way it's doubtful you will receive it reliably anyway.
That's the short answer or suggestion. Now for the more in-depth and longer answer:
Most transmitters broadcast either horizontally or vertically, meaning that the receiving aerial must be fitted accordingly. Rowridge is unique as a main, high power, transmitter in that it broadcasts horizontally and vertically and it has been doing so on all channels (COM7 excepted) from April 2011, which was when switchover had completed and all channels when to their full and final transmission powers.
However, the PSB (Public Service Broadcaster) channels which include BBC, ITV (and some of its sister channels), Channel 4 (and some of its sister channels), Channel 5 radiate at 200kW horizontally and vertically, but the main COM channels (COM4, COM5 and COM6) radiate 50kW horizontally and 200kW vertically. You are having difficulty with COM5.
(The reason for the lower power is because Crystal Palace (London) and Stockland Hill (Devon) use the same frequencies as Rowridge for COMs 4 to 6 only i.e. reduce the likelihood of interference. The PSB frequencies are not shared, which is why they can be on higher power.)
So, switching to vertical polarisation in an area with no where near favourable reception, which you are, will likely move you towards more reliable reception of COMs 4 to 6.
But, if you can receive COM7 (BBC Four HD, BBC News HD etc) then be aware that it is horizontally polarised only and is at 24kW. So if you turned your aerial vertical you would loose COM7. It is doubtful you will receive COM7 to any useful degree anyway, due to the large obstruction which is Butser Hill.
If your problem is too low a signal strength then you might get away with more amplification (booster) while retaining the horizontal aerial which might yield you COM7.

Is it not possible to transmit channel 29 freeview which includes QVC Extra, Pop TV and the local That's Solent from Rowridge vertically to enable those with a vertically pollarised antenna to receive these three services?

Can someone explain why ITV Encore on Satellite Channel 123 is being blocked by Sky TV in that you have to subscribe to Sky TV in order to receive it?
This channel should be free?
