For a broadcast of 6 watts, the transmission range will be 3 miles. At 15 watts, the range increases to 5 miles, at 40 watts to 10 miles and at 100 watts to
15 miles
.
How far can you transmit FM legally?
On FM frequencies, these devices are limited to an effective service range of
approximately 200 feet (61 meters)
.
Can you use 2 FM transmitters at the same time?
If you transmit the same FM signal from 2 locations,
the receiver will experience a similar effect as FM multipath
(when a single FM transmission
Can two radio stations have the same frequency?
In radio frequency engineering, an
overlap zone
occurs where signals from two or more radio stations, transmitting at the same frequency, can be received with comparable intensity. Interference occurs frequently in such a zone. … Alternatively, the signals could be separated using a demodulator in single sideband mode.
How far do FM radio signals travel?
VHF radio waves usually do not travel far beyond the visual horizon, so reception distances for FM stations are typically limited to
30–40 miles (50–60 km)
. They can also be blocked by hills and to a lesser extent by buildings.
How far can a 50000 watt FM radio station reach?
The most powerful 50,000 watt AM radio stations can be heard
within a hundred miles or
further in the daytime.
How far will a 2000 watt FM transmitter reach?
| Watts in ERP Kilometers Rural area | 2000 108 | 4000 152 | 6000 187 | 10000 241 |

Why can you hear two radio stations at once?
Fortunately, FM receivers are good at picking an
FM signal out of noise
, so your radio is able to separate one – or the other – of the two signals out of the noise. It does this by locking onto the phase of one carrier signal, which allows it to treat the out-of-phase signal as amplitude noise, which it always rejects.
How are you able to hear multiple stations on your radio?
Your
radio
‘s antenna picks up those radio waves and channels them to electric circuits inside your radio that convert them into sounds you can hear. … In this way, radio waves are much like ocean waves. Amplitude refers to the size of a wave, whereas frequency refers to how many waves arrive each second.
Can you transmit and receive on the same frequency?
Current tactical communication systems are unable to simultaneously transmit (Tx) and receive (Rx) at the same radio frequency (RF), placing an inherent limitation on spectrum usage imposed by conventional duplexing and networking techniques.
What is the least used FM frequency?
The lowest and almost-unused channel,
channel 200
, extends from 87.8 MHz to 88.0 MHz; thus its center frequency is 87.9 MHz. Channel 201 has a center frequency of 88.1 MHz, and so on, up to channel 300, which extends from 107.8 to 108.0 MHz and has a center frequency of 107.9 MHz.
Which travels farther AM or FM?
In AM broadcasts, sound signals are encoded by changing the amplitude, or maximum height, of radio waves. AM broadcasts use
longer wavelength radio waves than FM
broadcasts. Because of their longer wavelengths, AM waves reflect off a layer of the upper atmosphere called the ionosphere.
What is the most powerful FM radio station?
XERF
is the most powerful commercial radio station in North America and the third most powerful in the world. With its mammoth transmitter across the Rio Grande in Ciudad Acuna, Mexico, XERF can increase its signal up to five times the 50,000-watt limit allowed by the U.S. Federal Communications Commission.
Do FM radio stations reduce power at night?
Most AM radio stations
are required by the FCC's rules to reduce their power or cease operating at night
in order to avoid interference to other AM stations. … However, during nighttime hours the AM signals can travel over hundreds of miles by reflection from the ionosphere, a phenomenon called “skywave” propagation.
