How do you replace a car radio back the factory radio?

December 29, 2009 - 12:16 am 2 Comments

I just bought a 2001 Nissan Maxima GXE and the car has a Alpine radio that someone replaced the factory radio with. I would rather the factory radio in my car. Where could I find a factory radio to buy and is it expensive to have it replaced back to the factory radio?

What is the best available radio for good AM reception?

December 23, 2009 - 2:36 pm 1 Comment

I live in California and need a good radio that gets AM stations clearly. This radio is to be used at home.

I would suggest the GE SuperRadio III. Amazon has them and I’ve occasionally seen them in RadioShack Stores. They don’t look like much, but having used one in the past and comparing it’s performence to my top-quality Sangean ATS-909 reciever. The AM reception is unreal..picking up stations hundred of miles away with little effort and using the internal antenna (milage varies on location)

They can be had for about $45. http://www.amazon.com/7-2887-Superadio-III-Portable-Radio/dp/B00000J061

How are light waves and radio waves formed? What is the differance in the two?

December 21, 2009 - 12:02 am 4 Comments

I’ve heard that they’re the same thing? Why can we not see radio waves? Absence of photons? If that’s correct, why are photons absent in radio waves? Or am I just totally gone beyond the possibility of safe return?

These are formed by an acceleration of electromagnetic charge. electrical fields create magnetic fields etc. so a self propagating wave is formed. Yes, they basically are the same thing. All electromagnetic waves are essentially the same except in frequency, and hence wavelength. The strength is based on frequency.

You can’t see radio waves, just as you cannot detect some very low pitched sounds, under 40Hz and high pitched over about 20000Hz.

Why does the radio goes silent when starting the engine of a car?

December 18, 2009 - 5:13 am 4 Comments

Why is it that when you start the engine of a car, the radio goes silent for the duration of the ignition?

Like, you insert the key. Turn the key once. The battery to the car is on and the radio (if on) starts. You can hear the radio stations and everything just fine. But once you turn and hold the key further to start the car, all the sounds of the radio stop, but it’s still on.

What’s up with that?

The computer directs the power to starting the car, which causes this effect.

How to change the frequency of a radio transmitter?

December 15, 2009 - 2:38 pm 2 Comments

My radio doesn’t receive a signal from my radio transmitter, because it transmits at 900 MHZ; which is too high for a radio to receive.
I know i can just buy one, but this one has 300 ft range, and I LIKE MODIFYING THINGS myself.

SO, PLEASE HELP ME. AND MAKE IT SIMPLE.

Websites with tutorials are appreciated.

What are you trying to do? Control an R/C car, boat or airplane? What is this transmitter? 900 MHz sounds like a public service two-way radio. However, these radios have more than a 300 ft range. A 300 ft range would sound like a R/C transmitter but there aren’t any that work at 900 MHz.

I will assume you are are trying to control an R/C thing-a-ma-jig. R/C receivers work at 27 MHz, 72 MHz, 75 MHz or 2.4 GHz. If your R/C transmitter works in the same band as your receiver, you can change crystals in both the receiver and/or transmitter, fairly easy.

If you like modifying radio gear, get an Amateur Radio (Ham) License. You are allowed to build, experiment with and modify all the radio gear you want! Hams also use their gear for R/C.

Is it possible to put a cb radio antenne into a radio jack in a car?

December 12, 2009 - 11:08 pm 1 Comment

I have a Jeep Commander 2007. I was wondering if it is possible to somehow have my radio setup rewired to just a simple windshield mount inside my car and wire my cb radio to connect to the old radio antenne jack outside the car and put a cb radio antenne in the radio antenne plug outside the car. If so where could I find out how to do this and the things that i need to make an adaption like that. thanks.

Possible? Yes. Good idea? No. You will ruin your CB and your signal will be lousy. You must use an antenna designed for CBs. Now, there are windshield mount antennas for CB. With these type of antennas the antenna portion is affixed to the glass. The feed for the antenna is affixed on the other side of the glass. These work unless you have heating wire or AM/FM antenna in the glass between or real near the CB antenna.

If you want a decent antenna, put a 102" whip on the left or right rear. Jeeps look cool with those. You could also put a bumper mount antenna on. Various types of loaded (shortened) antennas can be mounted on top. Mag-mount antennas have magnets in the base. You can slap them on and pull them off. K40 antennas are nice. Some of them are also easily removable.

When you get an antenna, buy an SWR (standing wave ratio) meter. This is used to tune the antenna. You might find some shop to install and tune it for you instead.

Using a CB radio to communicate with two way radio, is it possible?

December 10, 2009 - 9:39 am 3 Comments

I’m a security guard and we use two-way radios for communication but I’m going to be getting a CB radio and was wondering if it’s possible to use it to talk to a two way radio. Like would it be the same frequency or the same channel as on the two way? Thanks.

Definitely not. CB channels are between 26.965 MHz (channel 1) and 27.405 MHz (channel 40). The majority of two-way communication radios use frequencies between 460 MHz and 470 MHz.

Looking in to advertising with one company that states our ad would run on their internet radio stations and go out to anybody listening to one of their stations in our specific zip code area. I don’t know if there are any neilson ratings for internet radio stations or not or even if this company is worth spending money on in the first place.In any event, I need to find out if there is a way to discover the most popular and highest ranked internet listened to radio stations.

How do you find this out? By bandwidth?

What is the most popular radio production software?

November 23, 2009 - 1:21 pm 1 Comment

I am starting a radio production course this year and I want to get some experience using the software that is used in radio stations for cueing the music and ads, and for talk over etc.

Anyone have any ideas what the most popular software is?

You need to visit a radio station because your idea of what is used in broadcasting is about as far from reality as it can get.

Radio stations have used basically the same equipment for 50 years or more… a MIXING BOARD, turn tables, tape record and playback decks and a whole assortment of audio sweetning EQUIPMENT.. they aren’t doing it at home on their PC… they are using, in some cases, State of the Art recording equipment… but at the other end of the scale.. out in the midwest… they don’t even have the basics, since their programming comes in by satellite.
