Anthony,

Unfortunately, the HD radios I've seen arbitrarily decide when the signal is 
strong enough, so they switch in and out of HD mode when the signal is 
unstable or noisy.  I wish they had mode switches similar to the stereo/mono 
switches we used to see on early FM tuners.  I'm always amazed at how the 
designers seem to forget that radio is an analog world.  I guess it's the 
same mentality that puts poorly regulated power supplies into computers 
where the voltages have to be rock steady.

Steve
