First listening, couple questions
Well I received my sony AN-LP1 Antenna, and tried it with my G5
tonight. It made Radio Havanah go from noisy to very clear with little static. However, this and other stations wax and wane in strength, even though it seems the radio is picking up the station well. Does this have a name? Anything I can do about it? Thanks. Just being able to get additional news stations make this worthwhile. Jim |

You can use an SSB receiver precisely tuned, or find one with Synchronous Detection. Like I said, a real radio. |

I see I did post twice, sorry. Odd I could not find my first post. Thanks for the responses. Well, I am wondering then if I should invest in something like the E1. Dave, is that a "real radio?" Jim |

It will all but eliminate selective fading distortion and replace it with a gentle sweeping flange. WARNING: You need to use a sync detector with BOTH sidebands to listen to an IBOC MW station. Not all sync detectors are capable of this. You can't listen to an IBOC station in ECSS either. |

If such a station was far enough away to present fading wouldn't that be far enough to render the sideband noise a moot issue? The digital stuff is in both sidebands and 180 degrees out of phase with itself. A simple detector sums to zero; a selectable sideband detector hears the digital crap along with the analog. |
