BA Receptor "HD" Radio -vice- Sangean HDT-1 "HD" Radio Component Tuner ? ? ?

It would need more knobs to be what you would really want, but it's pretty selective and sensitive, for instance, at least with the external antenna ; and it doesn't overload. I'm curious about your radio's AM selectivity. Is it always IBOC wide or does it receive normal AM stations with a normal narrower selectivity? Frank Dresser Audiowise, it's very selective as to hearing adjacent channel stations. You don't hear splatter at all. The AGC takes hits from the adjacent station audio, however. Which is why you'd want a knob for AGC fast/slow, for instance. -- Ron Hardin On the internet, nobody knows you're a jerk. |

Frank Dresser Audiowise, it's very selective as to hearing adjacent channel stations. You don't hear splatter at all. How do you think they're handling the differences in IF bandwidth? I suppose your radio might have seperate IF strips for the IBOC channel and the AM channel. The AGC takes hits from the adjacent station audio, however. Which is why you'd want a knob for AGC fast/slow, for instance. I've been wondering if these insensitive IBOC radios are inherently insensitive or if they're getting desensed by AGC action caused by strong nearby signals in a wide IBOC IF strip. These strong signals wouldn't get through a normal AM filter and would be unheard by the listener. Of course, this is all speculation on my part. Frank Dresser |
