What Hz do radio stations use?
The Amplitude Modulated (AM radio) carrier frequencies are in the frequency range 535-1605 kHz. Carrier frequencies of 540 to 1600 kHz are assigned at 10 kHz intervals. The FM radio band is from 88 to 108 MHz between VHF television Channels 6 and 7.
What is the normal bandwidth of an FM radio station?
The FM broadcast in the United States starts at 88.0 MHz and ends at 108.0 MHz. The band is divided into 100 channels, each 200 kHz (0.2 MHz) wide. The center frequency is located at 1/2 the bandwidth of the FM Channel, or 100 kHz (0.1 MHz) up from the lower end of the channel.
What is the upper frequency of a single with a bandwidth of 6 MHz if the lower frequency limit is 54 MHz?
What is the upper frequency of a signal with a bandwidth of 6Mhz, if the lower frequency limit is 54Mhz? Upper frequency = bandwidth + lower frequency = 54Mhz + 6Mhz = 60Mhz.
What is the limit for transmitter power on the 1.8 MHz band?
1500 watts
What is the limit for transmitter power on the 1.8 MHz band? The FCC sets maximum transmitting power limits (Peak Envelope Power) for each amateur frequency band. We are allowed to use up to a maximum of 1500 watts PEP output on the 1.8 MHz (160 meter) band.
What is the frequency for channel 1?
44 to 50 MHz
The frequencies shown are for the analogue video and audio carriers. The channel itself occupies several megahertz of bandwidth. For example, North American channel 1 occupies the spectrum from 44 to 50 MHz….France.
| Channel | Video carrier (MHz) | Audio carrier (MHz) |
|---|---|---|
| 1 | 47.75 | 41.25 |
| 2 | 55.75 | 49.25 |
| 3 | 60.50 | 54.00 |
| 4 | 63.75 | 57.25 |
Why do most amateur stations use lower sideband on the 160 meter 75 meter and 40 meter bands?
Which of the following modes is most commonly used for voice communications on the 160, 75, and 40 meter bands? To make communications consistent and to keep bandwidths to a minimum, the convention is to use lower sideband (LSB) communications for the longer wavelength (lower frequency) bands at 160, 75, and 40 meters.
What’s the difference between 29.8 and 29.91 MHz?

What’s the typical frequency range for a shortwave radio?
Most “shortwave” radios sold today actually tune a much broader frequency range that includes the AM broadcast band and parts of the longwave spectrum. A typical tuning range is from about 150 kHz to 30 MHz.
When does the AM broadcast band end at 1700 kHz?
The AM broadcast band now ends at 1700 kHz, with 1610 to 1700 kHz being the new “X” or “extended” band. New stations began appearing here in late 1997, and this new “X band” is providing excellent DX listening opportunities. 1700 to 1800 kHz: This is a “grab bag” of miscellaneous radio communications, mainly beacons and navigation aids.
