Default Anyone know why AM Radio "Hybrid Digital" sounds so bad?

Hello,

Well,if you mean the analog portion of the signal,on

AM they only go out to about 4900 hertz,which is

about like a land line phone or a 78 rpm record.

It is necessary because the total signal bandwidth

would wipe out even more nearby stations if they

ran more audio on the analog portion.

If you mean the digital part,it is because it is only

running about 24 kilobytes per second,which is not

even a poor MP3 quality.

And the digital is subject to noise,static etc. so the

receiver will default to analog often in (most) instances.

Hope this helps.....


24 kbps Shoutcast sounds better than AM HD.
