Hi hesperis, I reckon if you don't know what it is then you probably haven't got one! It is a small satelite radio with a small (couple of inches?) dish/antenna attached, I listen to a lot of radio and i was considrering buying one later this year, the price has dropped right down, they are now less than 100pounds, all the advertisments say that they are really good, but they would wouldn't they? So I wondered if anybody had bought one. or herd one.
