The strange thing is here in Brandon, the fringe of Sandy - there is no difference in the signal strength on C31 or C27 & both are solid no breakup on the channels - odd

I am a bit confused about wild differences in signal strengths I am seeing from Sandy Heath.
I understand why C31 is low, but why do I see this:
C24, Strength 6619069, Quality 100%
C27, Strength 6487999, Quality 98%
C31, Strength 4521926, Quality 68%
C48, Strength 2686917, Quality 40%
C52, Strength 131019, Quality 0%
If there was something wrong with the aerial and the way it was pointing, why would I get virtually perfect signal on two channels and poor (or absent) on others? It's almost like these channels are still on low power?

Don, where are you? - have you upgraded your aerial? If you have an old group A aerial, that will cause your problem. You may need to upgrade to a wideband & perhaps replace the co-ax if it has been there many years.

Thanks for your comments.
My problem arose because I could not find out how to retune. The instruction book had no reference to "retuning". A friend helped me when he pointed out that I had to click on "settings". What's in a name ? CONFUSION !

I have lost Channels 48, 52 and channel for the High Definition . That a huge part of the available offering.
These represent our preferred viewing channels and so are an unwelcome loss that was previously at good strength, then became very pixelated and poor strength a week or so ago.
Why can this be done without regard to viewers. Digital has been pretty good for the last year but now not.
I have tried auto retune and manual return and my experience reflects Don's.

steve: C31 is no longer in use at CP, so your SDN multiplex reception should now be perfect.
