How do motorola 2 way radios transmit a signal?
Two way radios should be set at the same frequency. Then, 2 or more persons can communicate with each other via those radios, by pressing buttons and speaking.
What Problems did the Radio solve?
Yes. At the beginning, listening audiences tended to be very small, or in most cases, zero. This was primarily due to two main reasons: 1). There were almost no people who owned radio receivers. 2). Those who did had no place to plug them in.
Will Sirius Satellite Radios work downttown surrounded by high rises?
Yes, the signal will not be interrupted by tall buildings.
Where can one buy cheap DAB radios?
DAB is a digital radio that can pick up a digital broadcast signal. Places like Tesco's, Sainburys and Argos usually have DAB Radios in stock at very reasonable prices.
How do XM radios work exactly?
XM radios use signals transmitted by satellites in order to broadcast. A signal is broadcast from the ground station and sent to one of two XM satellites that then are able to broadcast the signal to all the receivers owned by XM customers on the ground. The satellites take the signal they are sent, which is basically a mass of encoded data, and descramble the audio as well as the encrypted information with it which includes such things as the song title, artist, and genre in order to send them to the personal receivers in the correct format.
