It means that the lawyers for his network have WAY too much time on their hands.
Doesn’t make any sense to me. Seems like they would WANT us to know where to tune in-
I was just asking someone about the Dr. the other day-I used to listen to him all the time in the '80’s. I’m in L.A. and I don’t think he’s on here anymore. Or maybe I’m just not up late enough anymore 
Alright, I just gotta chime in on this one!
I’ve been listening to the Good Doctor since the 70s, and that isn’t easy for a Clevelander, as GrizzRich mentioned, since he hasn’t been on the radion here since the 80s or so. (I listen mostly on webradio these days.)
So far, no-one has mentioned the website that is better than the official website for Dr. D ifo:
The rec.music.dementia offical site.
This is the place to go to find the stations the last few posters were looking for. (Here to be precise.)
And they also have everything else you could want to know, including lyrics and artist info.
(And places that have archives of the show, although none of them are complete. So, richardb, your help could probably be very welcome.)
Dr. Demento I only get occasionally.
Happily, in NYC at least, Scott Shannon fills the void for funny music.
