How far will a 100 watt FM transmitter reach?
The extra power will allow the signal to penetrate more effectively.
Once again 100 watts on a 15 foot mast (flat land scenario) may only be effective for 5 miles.
Raise that antenna height to150 foot and the coverage could be increased to 50 miles..
How far can a 1 watt radio transmit?
Car, Boat, & Other Radios (Mobile & Fixed-Mount)Average Range Guidelines *WattageFlat Open Terrain (miles)Inside Buildings (floors)1 watt (UHF)2 – 36 – 82 watts (UHF)3 – 415 – 202 watts (VHF)3 – 59 – 115 more rows
Is shortwave radio AM or FM?
Shortwave (SW) radio operates on the frequencies between the AM and FM bands. Shortwave has the unique characteristic of traveling very long distances making it a powerful medium to reach the masses from even one transmitter.
Why do radio stations do station identification?
The *reason* for requiring identification, at least in most jurisdictions, is so that if a listener hears something they believe breaches the local broadcasting standards (or more egregiously, the law) they know which station it was that broadcast it.
Why is AM radio so bad?
AM stands for Amplitude Modulation and has poorer sound quality compared with FM, but it is cheaper to transmit and can be sent over long distances — especially at night. The lower frequencies of the band we use for AM signals creates a wavelength that is extremely large.
Which travels farther AM or FM?
FM radio waves also travel horizontally and skyward. However , due to the higher frequency of the carrier waves, the waves that go skyward are not reflected. They pass through the atmosphere and into space. Although AM waves can be received at greater distances than FM waves , FM.
Why did AM radio die out?
The decline in AM audio was due more to regulation than to method of modulation. One aspect of radio not understood by most listeners is the concept of occupied bandwidth, or the amount of spectrum that a station uses to transmit its signal.
What is the point of AM radio?
AM transmissions are much more susceptible than FM or digital signals are to interference, and often have lower audio fidelity. Thus, AM broadcasters tend to specialise in spoken-word formats, such as talk radio, all news and sports, leaving the broadcasting of music mainly to FM and digital stations.
How far can FM radio reach?
Reception distance 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 (48–64 km).
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.
What does K and W stand for?
Knight and WilsonThe Carolinian Coffee Shop was owned by brothers Thomas, Kenneth and William Wilson and their brother-in-law T.K. Knight. In 1937, the initials K&W (for Knight and Wilson) were adopted and K&W Restaurant was established.
Why does AM radio not work 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.
What does the W in radio stations mean?
All radio stations have a four-letter identification code. … The letters ‘N’ and ‘A’ were given to military stations, but ‘K’ and ‘W’ were assigned out for commercial use. Radio stations east of the Mississippi River had to start their stations with ‘W’, and stations west of the Mississippi with ‘K’.
Are old radios dangerous?
When properly repaired and inspected, these old appliances are safe to operate, but if the condition is unknown, beware. Antique Radios may also contain hazardous substances, see Antique Radios and Asbestos. Every antique radio I restore is made as safe as possible. … Stay with the radio while you are listening to it.
Why do American radio stations have weird names?
ELI5: Why do American radio stations have such weird names, namely just strange combinations of letters like WBEZ or CFRM or K-PAX or KGB? … The FCC regulates radio stations in the US so the stations have to give out their call sign to identify themselves on air.
Is broadcasting AM radio legal?
UNLICENSED LEGAL AM The legal limit for AM broadcasting is 100 milliwatts, with a maximum antenna length of about 10 feet (this is highlighted in Part 15 as well).
How far can a 50000 watt radio station reach?
The most powerful 50,000 watt AM radio stations can be heard within a hundred miles or further in the daytime.
What is the most powerful 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.
Is AM radio dead?
No, AM is not dead. But if you really want to improve it, bring back a technology that already “failed” … AM stereo. … Mandate AM stereo in any FM stereo radio,” Boone makes the point that analog AM stereo is still an option for broadcasters and that it would be an easy technology to re-implement.

How far will 25 watts transmit?
For example, a 25-watt marine radio will roughly have a maximum range of 60 nautical miles (111 km) between antennas mounted on tall ships, but that same radio will only have a range of 5 nautical miles (9 km) between antennas mounted on small boats at sea level.
