Hi. I live in Sevenoaks, Kent and have always received good Freeview from Crystal Palace transmitter - both before and after switchover. My main TV is connected to a rooftop digital aerial which is boosted and pointing at CP and I have another TV connected to an indoor aerial which is also boosted and pointing at CP. I'm currently getting excellent reception from both TV's. However, yesterday I received a message on my main TV telling me that I would have to retune on 9th May? - else I'd lose some channels. I only received this message on the TV connected to the rooftop aerial - not on the other TV connected to the indoor aerial. Interestingly, while retuning on the 18th April, my main TV showed some channels were apparently coming from Cambridge? Is there a transmitter in the Cambridge area which is about to be switched over during May? - and could I be receiving channels through my rooftop aerial to my main TV from two transmitters?

Steve, your roof aerial must be receiving signals from Sandy Heath as there is a retune event in May, if you go to the Sandy Heath page on this site the details are list.

Thanks Tim. Question is - If I retune as message suggests will I then get Sandy Heath local news etc? I would much rather stick with London news from Crystal Palace.

Steve, look on your menus for the manual tune option. Crystal Palace is on channels 23,26,25,22,28 (plus HD is on ch30)
Good luck

I agree with Kevin do a manual tune otherwise you will get
BBC East/ Anglia news no use to you in Kent.

Steve: Your most likely Anglia transmitter would seem to be Rouncefall and Sudbury (which operate on the same channels). These are higher up that Crystal Palace, so run the automatic tuning scan and unplug the aerial when it gets to 30%. If it's Sandy Heath that you're picking up, then its Public Service channels are 27, 24 and 21, so the unplugging aerial trick won't avoid these if they are able to be picked up with your aerial.
What I would say is that, presumably, Crystal Palace is the "main" transmitter and Sudbury or maybe Sandy Heath is/are in the 800s. If this is so, then what you've experienced suggests that the TV displays messages applicable to all transmitters to which it is tuned and not just the "main" one.
It "may" be that the message relating to the Sandy Heath retune is also broadcast by Sudbury and relays of the two. I wonder if this is the case as if it weren't, then there would need to be a way of "inserting" this message for Sandy Heath broadcasts and not Sudbury ones.

Thank you all for your suggestions - Something else I might try is to turn down the gain on my rooftop aerial amplifier - It occurs to me that I wasn't getting this problem before switchover and the digital power ouput was increased. The Triax amp gain is currently set on max (around 22 db I think) So perhaps I can reduce the sensitivity towards the other more distant transmitters and just home in on Crystal Palace. Interesting problem though - I wonder if anyone else is experiencing this overlap?

Steve, it may well be the case that there's now no need for an amp at all, bearing in mind that you also get a good signal from at indoor aerial. The other thought I had is your roof aerial still aimed at CP?

Got a problem with my Bush. Was fine before the switchover but now it just won't settle.

Kevin. I did wonder if it might need a tweak - but since it's attached to the top of the chimney, I will only try it as a last resort if other suggestions fail to cure problem. I think the aerial still "sees" CP as the prime transmitter because traditional channels (BBC1, 2, ITV1, CH4 & 5) are still all "London", so perhaps a retune will only juggle the other channels? Can but try it in May! Thanks again.
