The other day I noticed that I'd lost two of the key channels Antena3 and Telecinco. This usually happens when a couple of new digital channels become available so I retuned the box. Instead of gaining channels I lost more.
Eventually I climbed on the roof and wobbled the aerial around a bit - maybe it was a bit loose after last weeks high winds - safe back on the ground I tried again. Success. We now have 34 free to air TV stations and 8 radio. One of the new ones is called "Learn English". I think it must be owned by a bloke who wears a zip up cardigan because every time I've passed by he's been on.
