What are radio waves and what are they used for?
Radio waves are generated and modulated with the transmitted information at the transmitting station and radiated by its antenna. These radio waves are picked up by the receiver antenna, filtered from all the other transmitted signals, detected and demodulated by the receiver to recover the transmitted information.
What are the transmitting frequencies of Radio Tiempo?
Researching to find the transmitting frequencies for Radio Tiempo has provided a wide range of results. It appears that there are a wide range of radio stations known as Radio Tiempo such as YVOZ, YSQJ, WNEL and WLZL. Due to the wide range of listings for a variety of Radio Tiempo listings it is impossible to provide a true transmitting frequency.
Do you need a shortwave radio license to just listen in USA?
No. Except for brief periods during wartime, radio receiving equipment has never been regulated. Only transmitting equipment is regulated, for the purpose of keeping things orderly enough so that no transmitter will interfere with the signals of another one. (Personally, I think some receiving equipment should be regulated, specifically speed radar detectors. But that's just my opinion; I could be wrong.)
What does radio stand for?
It is a shortened form of radiotelegraph - apparatus for transmitting or receiving radio broadcasts. Derived from Radiophone and Radiotelography, words coined in the 1890's
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.
