In book 7 there IS a wizard radio. The kids listen to a pirate station to get the real scoop about what’s going on.

I stand corrected. I totally forgot about that -- which is why I shouldn't really read these books so fast. You forget things.

But does the wizarding world do radio or were those the same wavelengths as muggle radio that the pirates were operating on? (Seriously, I don't remember the description at all.)
