XM and Sirius are now the same company and they have no competition right now.
One of the main differences between satellite radio and FM radio is that there is a cost for satellite and FM is free. Satellite radio also does not operate using the same numerical AM and FM channels as FM radio.
Generally, it would cost the same as getting satellite radio for your car.
yes because you are using the same radio frequency but as a portable device
acording to what I found yes
A radio telescope gathers and focuses radio waves, or electromagnetic waves outside the visual spectrum. A satellite telescope is sent outside the atmosphere to become a satellite of either the earth or sun, unless it is sent outside the solar system like the Voyager spacecraft. Many satellite telescopes carry several types of telescopes in one package to gather as much information as possible, like the Hubble.
A "network" in radio is some kind of nationwide hookup or means of connection ... whether it's done with microwave, telephone lines, coax cable, fiberoptic cable, or satellite links ... that makes it possible for many radio stations in many different cities to broadcast the same program all at the same time.
Depends on make and model of car, tuner unit selected, and installation costs. If you want a satellite tuner that is NOT the same as your radio and want the cheapest attachment device to your windshield, $50-$60.
All of the radio models share the same battery life.
You can only "get" XM radio on your "home radio" if you have a XM tuner and a paid subscription. The XM radio service is service satellite based and does not utilize the same system as FM or AM radio in your local area. You must have an XM receiver and an appropriate antenna in order to receive XM radio. There are a few "home radios" that contain an XM tuner and in those cases with a paid subscription, you could listen to XM radio in your home.
If you start out with a solution and you put the same amount of solution in different types of glassware, it will always be the same no matter what.
Different types of soil have different nutrients so no.
The satellite takes pictures of the earth, and sends the photos down by radio, as a digital data-stream. Maybe kind of like the same way you send pictures to your friend's cellphone, you suppose ?
