WildCat FM /Happy radio for everyone
you can make Broadcasting station.-1

The technical staff of WildCat FM hopes for the thing that a lot of happy radio station can be done even if it is small to various towns.
'This page targets the aim of opening of the mini FM station, and the beginner who has already operated the mini FM station. Inquire without reservation in mail when there are an incomprehensible point and a question, etc. and the page is updated as understood easily... 'Contents that extend it from a rudimentary thing to a special content to page 150 are published in Japanese and English in HP of WildCat FM.

 

1. Let' s do the radio broadcasting.

When the radio can output broadcast by the electric wave for myself, will you become something happy? in the age today though the Webcast seems to be thought at once if it is said the wireless broadcasting privately done

the electric wave if it is called it radios...the AM broadcasting and FM broadcasting. The radio that uses the electric wave is not in the Internet radio, and : with a moderate tasting. There is Performance

From a usual radio if you put out the electric wave even if the comparison electric wave flies only at the next vicinity level Your voice is listening......This is the maximum charm of the radio.

Because the thing of broadcasting that uses the electric wave is said, having is not called a radio with the radio in the meaning that broadcasting (Broadcast) that doesn't use the electric wave is correct. Generally, the expression seems to be a mistake in said Internet radio. being said how many.....Quibble. 
 
 

2. What broadcasting is done on the radio.
Please look at the thing that the radio can broadcast by my electric wave by thinking. I think that the program that wants to try considerably and something the tune that wants to throw float on the head.
It is sure to become happy gradually if it thinks.

It is sure to be thought about a happier radio if it does all.
also good to see DJ in the bureau somewhere affecting it.
possible to taste it even in feelings of the pirate radio if it does like evil for a moment.

'Mr.gorou itoi' of the radio glory period though speaking is old
It is possible to become an old movie and Wolf Man Jack that became famous.

World of ultimate self satisfactory. However, everyone is hearing when doing only by the self satisfaction.
Later speaking of that again

  3. How can I broadcast the radio?

When "Mini FM" is driven by retrieving the Internet, it is done that it goes out considerably massaging it. A lot of companions who are doing are it is things. The page to which the establishment of the mini FM broadcasting station is supported is sure to be found. There are a lot of pages to which opening a station is supported excluding pages of us whom you are looking now. When HP of such mini FM station is found, mail is done word smoothly hesitate to do the mini FM broadcasting. The advice to support the establishment of your mini FM broadcasting station surely is sure to be obtained.
 
 

4. Why is the wireless broadcasting possible?
Radio station called this mini FM Radio Law
If it is "Nuclear this in the wireless station with a remarkably slight launched electric wave", and a slight electric wave, everyone can put it out.

Definition of unnecessary, slight electric wave of license

Article 4 of the electric wave method, and it is the one, and the electric wave provided, "The electric field strength is the one in the distance of three meters from wireless equipment below the bolt 500 micro per meter" for is nucleus this becoming empty strength of the electric wave to which mini FM by Radio Law can be put out permitting unlicensed in the wireless station with a remarkably slight launched electric wave.
 

 

5. Where do you hear the electric wave?
Strength of electric wave by definition of unnecessary, slight electric wave of license. 
in the distance of three meters, the electric wave of the bolt 500 micro per meter?!
The electric wave attenuates if there is no obstacle it is physical and followed.
3m/500uV--10m/150uV--30m/50uV--100m/15uV--300m/5uV--1Km/1.5uV
--3Km/0.5uV--10Km/0.15uV--30Km/0.05uV

it doesn't break out in the translation that disappears by the electric wave and disappears though strength of the launched electric wave attenuates.
No listening passes because it reached the limit of the reception sensitivity of the radio (receiver) used. The auditory sensation area changes greatly with FM radio and FM tuner used.

about from several 10- 100m of several (the pocket radio and the lower sensitivity radio-cassette) actually.... (badness)
When high sensitivity FM tuner and the antenna are used, 1km-3km is like the limit. if there is sensitivity 0.15uV, it is possible to receive even by the distance of 10Km and the thing of the (radio receiver) physically.
 
 

6. Thing necessary for broadcasting
1. Mind and zeal said that it wants to do happy radio.
This is the most important, and for radio station start-up as long as the zeal and the dream continue.  
Because the idea and inventiveness arise and the electric wave is output, it is necessary to find the technology.
The difference of basic technology becomes a big difference of the broadcasting quality for mini FM.
 

6a. Equipment to receive FM electric wave 
The reception is an important above all thing to output the electric wave.
Antenna, FM tuner, amplifier, and speaker for FM reception 
To receive correctly and to monitor the electric wave so that the electric wave may fly
it is necessary to straighten the reception equipment.  

What doesn't start the electric wave if there is no thing that can be neatly listened because it puts out the electric wave either.
Minimum reception equipment that an existing broadcasting can also identify the difference between the inclusion electric wave and the sound is necessary.
The thing that the sound that I broadcast and the electric wave cannot be managed when you cannot receive an existing broadcasting straight Please understand
The quality of the reception equipment becomes a big difference for a technical base to broadcast thereafter.
 

6b. FM transmitter
FM transmitters exist from a cheap thing to the costly thing surprisingly. 'it exists from a cheap thing that obtaining is easily obtained by the mail order to an efficient thing that obtaining is difficult a lot,
You may choose by thinking about the hoped performance and contents of the purse.
However, even if you see the transmitter sold for mini FM from the price for about several thousand yen with the thing of - about 100,000 yen
Only it toys moderate, it exists, and a few technology.. knowledge because the quality of the launched electric wave is also bad and there is a problem.
Never do because remodeling careless as the output is raised even in case of being invites a lot of risks. 
 
 
 
 

 

 6c. transmission Antenna for broadcasting to output electric wave

The hall debt part in the center part such as Yagi Antenna was used, and setting it up is vertically recommended though the antenna for FM reception can be used as it is for the mini FM broadcasting. the said hall debt dipole ..continuation.. antenna of (The acoustic radiation efficiencies are more excellent than the horizontal. )

The acoustic radiation efficiency is not good either, and because there are a lot of disadvantage the harmonic component such as spurious and for radiation and the electric wave trouble from the antenna, etc. because the band is wide, it is not possible to recommend and to do the design of the antenna such as the wideband antennas (Supar discone) moreover in wideband on the characteristic.

The possibility of physically causing the electric wave trouble decreases sharply to the antenna that was able to take the tune correctly.


 

6d. Machine that mixes sound(sound mixer)
A necessary number of channels is decided according to whether it broadcasts on the scale of which extent.
It is not if a real thing is not hoped of saying that the mixer is absolutely necessary especially.
Various things can make it drink by the application depending on the device, and something "Calla tub amplifier" be substituted enough for instance.
If CD etc. can be reproduced by being able to use the mike, anything is OK.
It is possible to broadcast immediately if there are CD radio-cassette and FM transmitter to be able to do the mike mixing.
 

6e. Machine that emits sound (CD&MD cassette etc.)
In CD and MD, the expensive apparatus is not necessary having so much.
As explained at the above sentence because the transmitter for mini FM cannot expect the performance more than the price
There is very no thing that the sound emitted from the transmitter with a CD player with good sound becomes good.

that makes wrong in place where you and money are spent very much. !
If it wants to broadcast because of high sound quality sound, money is spent in the transmitter first.

6f. Others(small articles such as Microphone)
The Microphone etc. from the friend in moderate zeal in case of being because it doesn't hope for super-high sound quality. it rakes up and the thing that seems managing to come to become it.
