Hi John,

I know you can't actually *hear* 9600bps modulation, hence my request for an 'indicator'.
I believe one way is that the white (background) noise goes quiet when 9600bps is being received.
Confirmation - (or strong denials) - of this would be appreciated from the digital experts among us.
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.
