had freeview for one year (no probs) from the Wrekin transmitter. But over the las week have had very bad breaking up from around 16.30 - midnight, then no sound from midnight to ??? Its fine in the morning when i get up (but sometimes needs resetting) im using the old ondig nokia box and my signal strength is full - normally. i didnt think it was a thermastat - due to the lenght of dissruption. any ideas what could disrupt the signal for that much time???
