Question about radios.

[DarkEnergy]

Some questions that were hard to ask Google.

Let's say I'm listening to 103.5 (kiss fm) in Chicago. If I were to drive to Cali, would I, 1. Be able to hear it still, 2. Not be able to hear it, it would just be static, or 3. A different station broadcasting on the same channel.

2nd question. What limits radio frequencies. As in, why can I only go up to 107.9. Why can't it just go past that.

Last question. Why aren't home radios as powerful as car radios? Instead you have to mess with that antenna crap.

(Side question) Can you get a car radio and set it up like one for home drawing power from an outlet?

1) It'd either be static or a different station. Here in San Diego, 103.5 is also KISS FM, so you'd hear the station, but a different broadcast center and possibly different radio personalities. 

 

2) Because that is the limit of the equipment's recieving/sending abilities.

 

3) Home radios generally have interferences, such as walls, roofs, and neighbors. Possibly, but you'd still have the same issues.

 

P.S. (If you want to sound like you are from "Cali", call it California. No one here calls it Cali

It would either be static or you would be picking up a different radio station under the same frequency.

2nd question. What limits radio frequencies. As in, why can I only go up to 107.9. Why can't it just go past that.

The FCC. They do this for both health and security reasons. There are things that broadcast on higher(and lower) frequencies(emergency services, military, other radio type services), but these need to be left free so that they work better. The 88-107 is specifically for consumer FM radios.

Last question. Why aren't home radios as powerful as car radios? Instead you have to mess with that antenna crap.

Generally they are lower powered, but you could set up a car radio in your house.

You learn something new everyday

1) The radio station that you are listening to in IL will not be the same as in CA. It will probably be registered for that region under a different telecaster.

 

2)The FCC currently limits radio frequencies. The radio band for FM is 88 megahertz to 108 MHz. 

 

3) The wave propagation for the FM radio is not BLOS (beyond line of sight) so a car/home radio antenna must be in contact with transmitter. The further the signal goes, or obsticals like mountains and walls will reduce the power, measured in decibels, and cause static. 

 

You can use a car radio in your house by getting a AC/DC inverter and connecting the proper wires to it to supply 12V.

This is all information I deal with everyday as a radio technician for the Air Force. I'm giving you the best answers I could in layman's terms.

That chart is pretty cool.

That chart is pretty cool.

You start memorizing it in my job...

 

If you have anymore questions just ask...
