HD Radio and AM Stations?

Question

I can't STAND when my AM sports station (broadcasting my favorite teams!) cuts in and out or gets static interference so I can't hear what's happening.

Is HD radio a solution for this? Are there HD AM Stations?

Answer 1

AM Can be heard on HD Radio, with better sound quility. It may not solve the static and interfearence, but it might sound better.

Answer 2

Amplitude Modulation is a sign wave that use the ground and air to transmit, it is also vulnerable to cross talk or interference.

Because of its susceptibility to atmospheric and electrical interference and the generally lower sound fidelity, AM broadcasting has attracted mostly talk radio and news

programming, while music radio and public radio mostly shifted to FM broadcasting which is more line of sight transmition.

Moreover, to fit more transmitters on the AM broadcast band, in the United States maximum transmitted audio bandwidth is limited to 10 kHz. The audio bandwidth of most currently manufactured radios can be half that.  In Australia 9 kHz

Medium wave and short wave radio signals act differently during daytime and nighttime. During the day, AM signals travel by groundwave, diffracting around the curve of the earth over a distance up to a few hundred miles from the signal transmitter.

However, after sunset, changes in the ionosphere cause AM signals to travel by skywave, enabling AM radio stations to be heard much farther from their point of origin than is normal during the day.

This can be easily observed by scanning an AM radio dial at night.

If the manufacturers have broadened the carrier band on the receiver width, then it may well be okay, I am not going to hold my breath on this matter.

The best you can do is extend your antennae as the cheapest option, as you may well have to do this if you bought a new receiver anyway.

Most HD stations are on the FM band, so far observed.

Answer 4

There are HD AM stations, but it depends if that station has a digital signal running.
