Voice scrambling of the audio.

I've recently bought a PRO-95 and am enjoying scanning.....

Several times now, while listening to our local police/sheriff channel,
I'll run receive an unintelligible message. The voices are very high
pitched, sounding like a cross between Minnie Mouse and Alvin the
Chipmunk, and I know they're talking but I can't quite understand what
they are saying. Superimposed over this is a loud ticking sound.

What have I run into??
