Getting To Know The Story About Radio Mikes

By Brock Hersh


Earlier on we used to have Audio mikes that used cables to transmit the audio signals. Long since these have been replaced with wireless or radio mikes that use frequency based transmission technology. They operate through radio waves and can transmit audio signals in FM, AM, UHF, VHF and various digital formats.

The advanced mikes are equipped to enable you to select a particular frequency band to transmit the signals from the mike so that it does not interfere with any other transmitter that can be operating on similar frequency. Coupled with this you are also able to use multiple microphones at the same time.

The current radio microphones owe their origin to the first original compander microphone that was built by Nady Systems in 1976. He was honored with Emmy award in 1996 in honor of his contribution to the field of technology.

Radio mikes are wireless and hence it is easier for the performers to use them on stage and it is a lot safer too when compared to the wires and cables dangling from wired mikes.

With Radio mikes that are wireless, the performers can be more relaxed and have ease of movement while performing. It enables them to move across the stage easily without having to tag the cable along. Secondly there is no need for cables to be joined and fixed together etc.

But then though they have such good advantages, they do have certain disadvantages too when it comes to the battery life. The two way radio batteries tend to get drained fast as the radio microphones guzzle more power in comparison to the cable mikes.

Radio mikes operate within a certain range only. This could be a drawback and you might have to buy higher end equipment to get wider range. Then there is also the risk of disruption of signals due to other equipments being used in the same frequency in nearby area.

Many times you will be constrained to use fewer numbers of microphones to be able to retain the clarity and avoid clashing of frequency.

How Walkie Talkies Became Popular

By Chris Murphy


Walkie talkies are very commonly used for communication between two points. The half duplex channels allow only one radio to transmit at one point of time and the other would have to just listen. It is only one way communication that is possible.

Unlike telephones that you hold near your ears to hear the earphone, the walkie talkies are fitted with both earphone as well as speaker in the same unit.

The handheld units are similar to box radio but fitted with an antenna and both units get connected to radio stations that transmit and receive messages from a fixed point or range.

The credit of inventing the first radio transmitter and receiver goes to Motorola. Motorola created and coined the word 'walkie talkie' and the model was called Motorola SCR -300 that was based on frequency modulation. This version was a backpack mounted version.

Motorola had first introduced the commercial version of the first hand held compact and self contained device by name 'Handi Talkie' which was the precursor of the preset 'walkie talkie'. This unit though was not as good in performance as the 'walkie talkie', nevertheless was the first commercial device available for use in industry.

Today 'walkie talkie' is being used in various sectors including defense, security, public crowd management as well as various consumer, entertainment and recreational businesses too. You get kideei 'walkie talkie' too for children to play with. The models, features as well as the prices vary depending upon the usage, range and other factors.

With improved technology the 'walkie talkie' have also become sophisticated, more compact and user friendly. The commercial 'walkie talkie' tend to be a lot of studier, bigger sets with protective casing and operate on limited frequencies but with clarity. On the other hand the personal and individual sets tend to be sleeker, compact and light weight and can operate on many channels that are available within the band, but tend to lack in clarity.

'walkie talkie' for kids are available in the market . These are built relatively using low technology as compared to the others and operate within a range of few meters. They are pretty cheap and do not require a license to use.

Satellite Radio Has Never Been So Popular: Why?

By Owen Jones


The current entertainment world is awash with ways of and goods for using up our free time and meanwhile filling our brains with mindless trivia and advertising junk messages. In between the programs and the music, the message is 'buy,buy, buy; from me, me, me'. This is one of the reasons why satellite radio has become so popular, but I will expand on that later.

One of the major reasons why people like satellite radio is because if you drive fairly long distances, you do not keep getting out of range of the station it took you ten minutes to find and look for another one.

Satellite radio stations tend to possess a large to very large footprint. In other words, you ought to be able to keep listening to the same station if you want without continuously retuning.

Not only that, but satellite radio is invariably digital in nature which means that the signal will be better and the ensuing sound quality will be far better as well. This means that the background noise that we have been conventionally used to has practically disappeared.

The sound from a good piece of digital stereo equipment is second to none. In reality an AF /FM radio cannot hold a candle to a satellite radio station.

The cost of satellite radio equipment has fallen dramatically, which has increased its public awareness and uptake, which in turn has improved sales and allowed the price to plummet further. Nowadays, a satellite radio receiver is as cheap as chips.

Not only that, but in the early days, in the Seventies and Eighties, parabolic dishes needed to be extremely directional. They had to be trained on the satellite as a satellite TV dish still has to be now, but a radio system does not have to be so accurate anymore, which allows them to be used in cars and boats.

If you get fed up of the adverts that continuously drone out of terrestrial radio at you, it can be a good idea to find a satellite radio channel that suits you and subscribe to it. For $10-12 a month, you will get the type of programming that you prefer without all the ads!. Isn't that magnificent?

As with all forms of entertainment, at the end of the day it is up to the end user to choose whether the cost of satellite radio is acceptable, but one thing is for sure, satellite radio increases one's choices.

If you are fed up with the present range of radio stations in your area then the thousands of extra, frequently world-wide stations available to you on satellite radio may be just the thing that you are looking for, particularly if you are searching for a station in a foreign language that is not covered in your neighborhood.

Getting Into DJing

By Angel Philips


Your DJ mixer is used to control the sound volume that hits the speakers and is placed in the center of your turntables pro CD players.

Also, it will allow you to lay down some pretty sweet effects to make your sound 100% unique. The more unique you are, the more you will stand out from the rest.

If you're using some kind of software for mixing on your personal computer, it would then be plugged into the mixer, just like a turntable.

Playing vinyl is what the old school DJs do. The beginning to DJing was created on turntables and most would never go into the digital DJ world.

Also, you have to lug around heavier equipment that is pricey. Nowadays is does not have to be such a challenge.

There is a lot of people out there who prefer a turntable that uses CDs. instead of starting a vinyl collection, they can simply use the hundreds of CDs they have.

They can also increase or decrease the tempo of one song and mix into another song from a different CD. This keeps the music flowing freely while everyone stays entertained.

Whether a beginner or an expert, a DJ need a decent pair of pro headphones. There's a number of brands that sell Dj headphones and you can simply choose a design that fits you best.

While your current mix is being played, you are secretly setting up the next thing for people to hear. You can always be one step ahead of yourself before anyone hears what you play.

In order to be a great DJ, you need to know all types of music from all genres, not just the top hit songs that play though out radios in the current day.

You also need a personality that people can flow with. And you need to be confident. That does not seem to hard hard, does it?

You just arrived at your gig with a boat load music to mix. But, some times there might only be a certain genre that people are into, or your audience might be very diverse.

Always try your hardest to give your audience what they want so they ask you to come back. This will result i more jobs for the future.
