What determines the range and distance of FM radio signals?
WilliamAsaba
quite a few things come into play. FM stations are basically LOS (line of sight) frequencies, this means that the radio waves will not propagate off the ionosphere. The frequency wavelength is too small to be reflected back to earth so they punch through out into space. The curvature of the earth plays a big factor in how far you can get a FM signal. If the transmitting station is lower in altitude than where the receiver is then the signal will go further. At times due to atmospheric changes you can get a AM radio signal to bounce so you might pick up a signal from Boston up in Alaska but that is not normal.

Why were long-range radio signals important?
so people could communicate over long distances
How does the Vor work for us to find the direction?
Vor is an abbreviated form of VHF Omni-directional Range and is a kind of radio navigation system for aircraft that emanates two types of signals - one directional and the other a 360 degree radial omni-directional. The Phase comparison gives what radial you are on by the position of the needle while DME determines the distance based on timing. It kind of works like a GPS.
Why is radio better than tv?
One advantage of Radio over Television in this day and age is accessibility. Television broadcast has been limited to digital signals with a more limited broadcast range. Radio is still analog with a much larger, generally, broadcast range. Radio also tends to be less distracting to drivers...
Why does a radio start at 88.1?
In the USA, the FM stations are licensed to operate on frequencies between 88 MHz and 108 MHz. That's where they all are on the dial. If you want to listen to FM radio, that's the whole range that you need. If you want to receive other things on radio, like foreign broadcast, ham operators, time and frequency standards, aircraft communications, GPS, cellphone signals, Bluetooth signals, WiFi signals, satellite radio, garage door openers, satellite TV, fire trucks, taxis, police, or truckers on CB, then you need a radio that covers different numbers.
Range of radio telemetry?
There are two kinds of telemetry--one-way, where the remote device sends instrumentation signals to the receiving station; and two-way, where the receiving station can send control signals back to the remote device. The range is literally unlimited--deep-space probes have two-way telemetry gear on them, and it can take months or even years to transmit a message from the vehicle to the earth.
What are the strength and weaknesses of radio?
Strengths: No wires, No Los required, greater range possible. Weaknesses: Signals become weaker over distance. Wireless signals can be intercepted so security is an issue.
What technologies allowed radio signals to reach a wider geographical range?
satellite
What technology is used in a radio?
Wireless Transmission Technology makes Radio devices tune to specific frequency and play the audio being transmitted from Broadcasting Radio Station.Broadcasting Radio Stationbroadcasts audio signals (from Recording Studio)asradio waves to Radio devices within Radiowave signals range.

What is atmospheric bounce and how is it beneficial?
Atmospheric bounce is a technique used by Amateur Radio operators - to increase the distance their signals travel. Some frequency bands in use by amateur radio enthusiasts have a limit on the amount of power their equipment can produce. This often restricts the distance their signals can travel (sometimes to just a few miles). By using atmospheric bounce, an operator can 'reflect' the radio signal off the upper atmosphere (like shining a torch on a mirror) and thus the range can be (often dramatically) increased.

How long has Earth been broadcasting radio signals into outer space?
Radio signals on Earth have been travelling outwards for almost 100 years, but the range is not very great because they go below the level of galactic noise quite quickly as they spread out.

How far is the range of a Cobra CXT545 2 way radio?
The range of a Cobra CXT545 2 way radio is the same as that of a cell phone that reaches satellite for transmission purposes. The Cobra CXT545 2 way radio range can be extended with upgrades that are available by the manufacturers. But for the most part, the CXT545 2 way radio uses radio signals to the nearest radio tower or to the cell phone towers that are in abundance in today's modern day world of technology.
The ____ function determines the lowest number in a range?
The MIN Function determines the lowest number in a range
How do Wi fi connections work?
Wi fi is Internet access using radio waves (signals) rather than cable to receive and transmit data. Wi fi requires a wireless adapter to convert data to radio signals. Your computer requires a wireless router to receive and decode the transmitted radio signals then to relay them to Internet using Ethernet. Wi fi has a range of about 300 feet, so transmission and translation need to be close to your computer.
What is a high gain antenna, and how do I use it?
A high-gain antenna is an antenna which allows for precise targeting of radio signals due to it's use of a narrow radio wave beam. To use a high-gain antenna you should put attach it to a high, clear surface to allow it maximum range to receive and send radio signals. A good place would be the roof of your house.
