What does HD1 mean on radio?
In one example, HD1 is the main FM radio station and HD2 is a feed from an AM station owned by the same broadcaster. Talk radio and news-only broadcasts that require less overall bandwidth are also common uses for HD2 and HD3.
What frequency does AM radio operate on?
The AM band in the United States covers frequencies from 540 kHz up to 1700 kHz, in 10 kHz steps (540, 550, 560 1680, 1690, 1700). 530 kHz in the United States is not available for broadcast use, but is reserved for the use of very low powered Travelers’ Information Stations.

Does HD Radio sound better?
Appropriating an abbreviation from high-definition TV, HD Radio offers better sound quality than AM and FM radio bands. It also allows stations to add more programming via several additional channels that can be broadcast “alongside” a station’s main frequency.
What is the bandwidth for AM wave?
The full audio spectrum ranges up to 20 kHz, but AM radio limits the upper modulating frequency to 5 kHz. This results in a maximum bandwidth of 10 kHz.
How do I check the bandwidth of my AM signal?
Bandwidth of AM wave which is required for amplitude modulated wave is twice the frequency of the modulating signal and is represented as BW = 2*fm or Bandwidth of AM wave = 2*Maximum Frequency.
What is AM radio used for?
In many countries, AM radio stations are known as “mediumwave” stations. They are also sometimes referred to as “standard broadcast stations” because AM was the first form used to transmit broadcast radio signals to the public.
Do I have HD2 radio in my car?

Why does HD Radio sound so good?
Digital technology allows a radio station to transmit more information in the same radio wave. Primarily, this means higher quality sound. So much more so that FM transmissions can sound nearly as good as CDs, and definitely much better than the hollow sounds of old analog FM.
Why does AM have bandwidth?
The bandwidth of an amplitude modulated signal is of importance for many reasons. The amplitude modulation, AM bandwidth is important when designing filters to receive the signals, determining the channel spacing, and for a number of other reasons.
