A radio programme receiver does not need to be directly in view of the transmitter to receive programme signals. For low frequency radio waves diffraction can allow them to be received behind hills, although repeater stations are often used to improve the quality of the signals.

What is a software defined radio?
Software defined radio is a communication module which has hardware components which rely of software programs to run. This mainly entails receivers and transmitters which are used for radio communication.
Who regulates electronic media?
Federal Communications Commission

Why does radio and satellite reception deteriorate when the sun goes down?
All satellite equipment, whether it be for communications, TV or radio, operates on its own specific radio frequency to communicate with the satellite. Light also gives off a radio frequency. "White light" which is what the sun gives out, is a full spectrum frequency. This means that every radio frequency there is, the sun is emmiting. So for you, when the sun goes down, the satellite which your radio equipment gets its signal from is probably in the path of the sun. Since the sun's rays are so powerful it inteferes with the satellites signal to your radio equipment. Let me know if I am right on this, you have XM radio. I am a satellite communications systems operator/maintainer in the US Army. Just curious because the XM satellites are geostationary which means that they are constantly in the same place in the sky in relation to the ground. You probably wouldn't have this problem with Sirius radio because their satellites have a highly elliptical orbit which means that there are multiple satellites moving over the western hemisphere where there are always two moving across the skies over North America. Since there are two always in the sky in different locations, if one was in the suns path, your radio would receive its signal from the other. Just as a little satellite humor, we sometimes have problems with our equipment when we try to locate the satellite in the sky. If the satellite is near the sun, our dish sometimes locks onto the sun. A couple of times I've seen when the sun crosses the path of our signal, the dish will start following the sun and we lose communications.
What act provides the same protection that covers mail and telephone communications to electronic communications such as voice mail?
electronic communications privacy act
Broadcast radio used widely for mobile communications?
Cellular Radio
What are the words used to describe intercepting radio communications?
Listen In (intercept radio communication)
Word meaning to intercept radio communications?
to intercept radio communications
What mode of communications does radio equipment deal with?
The mode of communications radio equipment deal with is radio frequency communications. Due to the concern of public safety radio communications now send signals digitally.
Does diffraction hinder radio reception?
Diffraction helps rather than hinders radio reception. Computers, monitor screens, and halogen lights are examples of things that can hinder radio reception.
What humans use radio waves?
Radio waves are used to transmit signals from a radio station, and you can receive the signals with a radio, and hear them as sound such as speech or music. The long wavelength of radio waves makes them a suitable medium for transmitting over a large range. it is also use in agriculture...... it is used to diagnose different diseases
Are Radio communications only used with 2 way radios?
No, radio communications are not only used with 2 way radios. They can be picked up on many frequencies, that are not necessarily considered to be 2 way radios.
Is there anything similar to the telephone?
radio communications cellular (radio) communications telex

Bravo
What word is used in international radio communications to denote the letter W?
Whiskey
How many parts of electromagnetic spectrum are used for communications?
Every part of the electro-magnetic spectrum could be used for communications however the most exploited are long radio waves, short radio wave, and micro-waves.
