5. Preparation for opening a radio station

When necessary machine parts becomes complete, let's prepare opening a station. !

1. Monitor

Reception of FM electric wave first of all The antenna for FM reception is set up. The thing that the electric wave can be correctly received is basic because it outputs the electric wave. if an existing broadcasting electric wave cannot be correctly received, it becomes a story not to be able to monitor the electric wave of the Broadcasting station naturally. !! After the first one step's for the thing that correctly receives FM electric wave and monitors it to open mini FM existing, and opening a station, it is a matter of paramount importance.

I do not think that it has the qualification that outputs the electric wave of mini- FM in case of being because it cannot correctly receive an existing broadcasting electric wave.

All temporarily the frequencies are monitored and will be seen by me. The dial of the tuner is seen, and all frequencies are listened slowly and seen in turning 100KHz step.

Up to now, it listens and it is sure to be surprised at the existence of the FM station, and even Tokyo Nakano (Mini FM is excluded) who has WildCat FM can receive the electric wave of FM station that reaches 33 station by setting up an excellent reception antenna.

2. Decision of transmission frequency

if all frequencies are monitored and seen with FM tuner it is thought coming, might not be received the influence of an existing broadcasting station, not be influenced an existing broadcasting station, and be a thing that an effective frequency can be chosen that nature is rapid. where it is necessary to output the electric wave The electric wave is correct and the thing that can be received is basic even in case of being selecting a frequency...

3. The broadcasting station name is decided.

The person who listened to the radio by chance is surprised at the electric wave of the mystery when the electric wave is output suddenly. The broadcasting station name is necessary to clarify the identity. Moreover, in the future, the person who listened to the radio by chance will be important listener.

it seems to be it and the atmosphere of the broadcasting station rises when the call sign, the formal bureau name, and the bureau pet name, etc.
are decided. However, do not do how that mimics a regular call sign from which existing broadcasting stations such as JO**-FM and JOZZ3**-FM were given by the Ministry of Public Management, Home Affairs, Posts and Telecommunications to put it. it becomes a malfeasance by point ..JO**-FM.. departure from the call sign very ..the putting use... JO** that adheres to the head of the call sign of the broadcasting station is an international call sign that the Ministry of Public Management, Home Affairs, Posts and Telecommunications has come into effect to the bureau license.

By the way WildCat FM The broadcasting station name : the call sign with WCAT-FM WildCat FM,

When you put ID!!
WCAT-FM.WCAT-FM This is Performance Broadcast Station WildCat FM.
This broadcasting is Performance Radio that has been privately managed in Nakano Another and E-Mail address etc. of announcement of telephone number that clarifies identity by feeling. The thing to make distrust not given to the person who listened to the radio is an important thing by chance.

4. Examination electric wave

When the transmission frequency is decided, the launching preparation of the examination electric wave is done. Let's do the setup and fine- tuning the frequency of the transmitter. Whether the dummy antenna (dummy loading) is connected with the transmitter, the power supply of the transmitter is turned on, and the electric wave has occurred by the set correct frequency are confirmed.

The transmitter for mini FM that confirms the transmission frequency if there is a frequency counter and sees recommends the confirmation of the frequency counter because there are a lot of one with doubtful accuracy of the transmitted frequency.

The accuracy of the transmitted frequency has not gone out of most products because the price of the transmitter for mini FM is also moderate no matter how it is called a transmitter of PLL.

The problem did not happen if it was an age of an analog tuner. The gap of about 10KHz becomes a fatal problem as for the gap of the frequency now. For instance, the gap permitted when the electric wave is output with 88MHz is better the thing that is the range of 88.00 xxxxMHz even if it belittles it.

The phenomenon such as distorting the sound when the distance parts as the distance of a jump of the electric wave is short when the frequency shifts occurs. When the center of the frequency shifts on the sending end and the reception side, let's understand the thing that correct sending and receiving cannot be done.
 

Let's launch the examination electric wave in the meaning that avoids an unnecessary risk at midnight. it is because there is a possibility that an unexpected jamming wave goes out of a transmitter and a defective antenna for the adjustment. Do give to me with scrupulous care, and is the television screen safe? if 100m a slight electric wave.
electric wave flies, the said thing doesn't become it of the television and the other in the range of 100m when the said thing is forgotten when there is a possibility of giving telecommunications equipment the electric wave trouble. Let's confirm it with scrupulous care.

Please do a correct monitor with FM tuner efficient when you launch the examination electric wave. The setting of the sound because of what sound like the sound concept etc. of the bureau broadcast etc. are tested.

Let's set the start based on the sound that listens easily though it is understood to want to emit a good sound. This is considerably difficult, and it changes because the sound is different because of received component and radio. The basis of the sound is Flat. Moreover, it is strict prohibition that raises turning up the volume carelessly or the upper register. Because the band extends by the emphasis in high pitched sounds, the broadcasting electric wave of FM listens to the electric wave trouble to the adjacent bureau and has the possibility of causing it.

Moreover, when the examination electric wave is launched, ID is put without fail and the identity is clarified.
 
 

#. Electric wave extra chapter 1

There is correctly no expression said that the electric wave will fly by 100m, and the launched electric wave actually disappears and, because, doesn't disappear. The electric wave that you launched keeps infinitely flying to outskirts of space.

it reached the limit of the reception sensitivity of the radio, and the range where I hear by the reception sensitivity of the radio changes into not hearing the electric wave by about 100m. The sensitivity difference of the radio has from 50 to about 100 times differ in being surprised.

in the radio of high sensitivity car radio etc. , the surprising electric wave also in the remote place is and there is a thing that can be received.
 
 

6. The final check of machine parts

if the launching of the examination electric wave ended without trouble. The transmitted electric wave is received and the thing whom can surely be monitored is top priority though it comes for eyes to tend to be deprived by the equipment and the transmitter that emits the sound that finally checks machine parts.

Because the voice of the bureau electric wave is not understood even if an extreme story and the electric wave stop if the reception can be neatly reproduced and it doesn't exist, it becomes a story before broadcasting. !! it is a case that is often and cannot laughed though is a funny story.

As for the sound of the transmitted electric wave, it is basic to listen to the sound received with the tuner (air Monitor).

7. Opening a broadcast station
air Monitor and the setting of OK and the sound that listens easily are in order and it is opening of long-awaited mini FM station.

However,
There is no difference in the broadcasting station with the mini FM station.

if the broadcasting electric wave is output even if it is legally a wireless station to which permission is not needed, it is recognized the broadcasting station and will receive the restriction of Broadcast Act.

As for this, it is the document the following new and the broadcasting superintendent general Chapter 7 paragraphs 2 though amplification will be done 5(6).


(6)The inspection by regulations of clause 3 in Article 73 clause 1 or clause 4 or Article 82 clause 2 is refused the one : with the inspection though becomes popular between young people recently at the time of frequent checkups and the occasional survey it mini FM wireless station ..punishment (Article 111) to penalties of the following penal servitude or 200,000 yen or less in June.. ..(... This is provided for, "it puts from wireless equipment on the distance of 100 meters by the one that corresponds to the wireless station with a remarkably slight launched electric wave, and the electric field strength is the one below the bolt 15 micro per meter" by one Article 4 clause 1 title of the electric wave method. Therefore, it establishes in there is no license by regulations of clause 1 in clause 4 like future when the one to exceed this is established or is operated or it operated, and it becomes the penal servitude of one year or less or the penalty of 200,000 yen or less as penal regulations. Moreover, the person who refuses, disturbs this when there is an inspection about this equipment or did should note it enough because it is punished to the following penal servitude in June or penalties of 200,000 yen or less.

(note 1)About physical electric field strength, distance vs.500uV of 3m said well and distance vs.15uV of 100m are the same things now.
(note 2) Present penal regulations is a penal servitude of one year or less or a penalty of one million yen or less.


Wireless equipment is legally legally inspected in the shape called mini FM wireless station as stated above. (it is Broadcast Act and a broadcasting station if it puts it out with the wireless station and broadcasting Hatai if the electric wave is output in Radio Law. )Because the inspection of this Article 73 is an inspection of the broadcasting station, it is "it is red" said the legal recognition as the broadcasting station where mini FM is splendid. Mini FM is a legally acquired, splendid broadcasting station if it paraphrases it.
it is wonderful. it is interpreted that it becomes the object of the restriction even if it is electric field strength in the standard and it exists if the electric wave that fills the reference value provided by Radio Law has not been put out when the inspection is received naturally the mini FM station and the it is natural.

Therefore, no contents of a letter it and ? for former like the place etc. with sentences said, Mini FM wireless station becomes popular between young people" etc. neither or the Ministry of Posts and Telecommunications Radio Regulatory Bureau Broadcast Department alone to do and to be able to look for the understood depth to mini-FM wish us in doing mini FM when wanting it based on Radio Law and Broadcast Act. Moreover, it is believed that you of the present Ministry of Public Management, Home Affairs, Posts and Telecommunications and a little connivances can be done for electric field strength if it is an accurate, beautiful electric wave that fills the standard of the law, tone quality heard easily, and it exists.

#. Electric wave extra chapter ?
mini-FM electric wave 100-meter broadcasting suspicious.!!
Electric wave that can be output by permitting!!

it is a big misunderstanding though a strong electric wave can be output by restricting Radio Law and the talk is often heard recently.
if it is about 100 meters, from the electric wave can be output by no permission and might be interpretations because it puts on the distance of 100 meters, and the electric field strength had been described in old times below the bolt 15 micro per meter.

it puts on the distance of three meters now, and the electric field strength has been described below the bolt 500 micro per meter. (Physical electric field strength is the same. )

it has not been changing physically for electric field strength of a slight electric wave old times and now. it is the measuring method and to change only.

The obstacle is avoided now at the time of built of the house etc. it was only changed to the realistic method that the transmission antenna at close range measured because the thing that secured the prospect distance of 100 meters and measured it was an impossible current state.

if there is no obstacle.....
it puts on the distance of three meters and electric field strength is electric field strength of the bolt 500 micro per meter.
it puts on the distance of the equal sign
three kilometer and electric field strength is electric field strength of the bolt 0.5 micro per meter. Can you understand though are thing ? it is physically the same thing.

The misunderstanding that can fly until writing a lot of distances is far the electric wave are caused.

in the world of mini-FM, it is a current state that such ignorance and a superstition are flooded as natural. it is not made to be puzzled to the superstition and the rumor, etc. , and it wants to learn a correct technology and knowledge and to get opening mini-FM by me in the future.
 
 
 

#. Electric wave extra chapter 2(story with dream)

The electric wave the your launched doesn't disappear if it wrote ahead. The electric wave that you launched theoretically keeps infinitely flying to outskirts of space though it might be a slight electric wave. Existence as the electric wave that might receive the interference of other strong electric waves and was transmitted is certain. if the reception device that transcends the dimension and the space exists, form might be able to be recovered in previous space how many light-years it. However, not disappearing is true understood your message, and theoretical the electric wave transmitted though it is another story.

#. Electric wave extra chapter 3(overseas mini FM)

There is mini FM transmitter KIT that the company that says United States Ramsey Electronics is selling, and the link below famously patted is the manual in mini- FM of FM25 and the saying foreign countries.

[FM SYNTHESIZED STEREO TRANSMITTER FM25B MANUAL]

Though this production manual are also as much as 36 pages and is explained in detailThe explanation and the operation method of Radio Law in the United States etc. are being written in detail nine paging in that. I also want the manufacturer in Japan to learn it by all means.

When the copy service of the material of Radio Law is received from FCC (United States TEL) for 24 dollars for mini FM and the electric wave trouble occurs in the thing to have to study with, the television, and the telecommunications equipment etc. of the radio and others, the Socsocha thing.

Thing that do not mimic call sign of existing broadcasting station though it is thing explained at above sentenceA minute book is withering until becoming how to apply the bureau name. it is material that the person who will open a T.V. station in the future and the director of a bureau who has already operated mini FM want also to get reading by all means, and page 26 of the electric wave and Radio Law is being written because it serves as a reference.




You are a director of a bureau in the broadcasting station from today. Please do a happy broadcasting toward the listener who is listening to a broadcast though it is a mini frequency modulation broadcasting bureau of a slight electric wave. The listener is sure to be waiting for broadcasting of you familiar who cannot listen in other broadcasting stations.

To a familiar person and the future... this is broadcast.!!
