I'm by no means an expert on 9600 bps modulation, but the few times I've tried it, I found that there is a different noise-like sound when you have it tuned in, but it definitely does not go quiet. There's pretty much no way to describe the difference - it's a bit softer, perhaps, maybe a little higher pitched (less low frequency components). I expect you'll recognize it when you hear it.
