We have three Freeview tellies, all Sony's. I live within line-of-sight of the Sandy transmitter mast - I can see the lights on it from the garden. And yet, we regularly "lose" channels. The main TV lost Ch28 (E4) this afternoon, plus several others I didn't bother making a note of. A retune has brought them back. The PVR has also lost Ch28, so I assume it's them rather than me (I can't retune it until it has no pending recordings, so that'll get done tomorrow.)
However, the one in the bedroom (which faces Sandy), which is on a set-top aerial is being even weirder. I had the "missing channels" thing a couple of weeks ago, so I retuned it, and now Ch's 2,3,4,5 & 6 are missing completely. In analogue days the signal was so strong in this room we didn't need an aerial at all...
So, what's going on? And how do I get my missing channels back?
