But here is a difinitive answer (I think)

I work on a newspaper in Cumbria and we run a weekly quiz. This week
one of the questions is: "How many short wave wavebands are there?" And
the quizmaster's answer is: Nine. Is he right? I thought there were
dozens of them?! Anyone able to confirm or deny the quizmaster or come
up with a right answer? Many thanks
