入院中は和文でも勉強して少しでも覚えよう。なんて思ったものです。胆石の時も、脳梗塞の時も。ところが、今時の入院はスマホ、タブレット、パソコン持ち込んで何でも出来ちゃうから、SNSのやり取りやYouTube見たりでやることたくさん。楽しんじゃって全然暇じゃない。(笑)
結局ほとんど覚えられず、身につかずでした。
人生もそれらに食い潰されてますね。

昨日は車の車検でした。早いものであれから三年になるんです。前の車との突然の別れ。それを受け入れてから。今の車はとても良い。壊れるまで乗り続けるつもり。ヘッドライトマニュアルでオンオフ出来る最後の世代かな。アイドリングストップは要らないけど。
と言うわけで、買って２年目に付けたフロントのタワーバーに続いて、今回はドロースティフナーを付けてもらいました。これで強化パーツは一通り付けたSP仕様になりました。ハンドリングが少しシャープになった・・・気がします。シート、スポーティーなものに変えたいなぁ。レカロとは言わないけど、スバル車のパーツでいいの無いかな？おとなしく普通に運転しているから明らかな差はわかりませんが(笑)
塗装の状態は良く、ほぼキズ無しのピカピカを保っています。
秘訣は、極力塗装に触れないで過ごすこと、かな。年に数回しか洗車しません。やっても流水の中マイクロファイバークロスで撫でるような。強く何かを当てない事が大切です。
車検で洗車してもらったので引き取ってすぐに上からシュアラスターのゼロウォーター塗ろうと思ったのですが、昨日は風が強く既にホコリが乗っていた感じがあったので施工しませんでした。
新車納車時にやってもらったガラスコートの上からゼロウォーター、と言う、二重コートでやってきました。今のところ良好で問題無しです。親水系とは言えまあまあ弾きます。ガラスコートの上だからかな？
塗装は樹脂。プラスチックみたいなもんでキズつきやすく、塗装は保護膜だけど塗装も保護しようと思えば扱いは繊細なのです。
もう少し乗り回さないと勿体無いですね。早くのびのびとお出かけできるようなご時世になるといいですね。
ガソリン高騰。困りました。早く平和になりますように。

Amateur radio club in elementary and junior high schools

In 2011, there were really various disasters all over Japan. It was also a year when the weaknesses of this highly information-oriented age were exposed. Cell phones were almost useless in emergencies, and although the Internet and e-mail were reasonably strong, it was only because of the efforts of the shadows who were desperately trying to switch the available lines. The importance of a battery-powered radio was reevaluated. But information is a one-way street.

As a two-way communication method, what can be used in times of disaster is "radio communication with its own radio waves. Cell phones are also a form of wireless communication, but they are merely a terminal because they are connected to the infrastructure of another power. If the infrastructure is broken, nothing can be communicated. If the infrastructure is broken, nothing can be communicated. The number of lines is limited, and if the lines are crowded, calls cannot be made even if the infrastructure is not broken.

If your own signal reaches the other party, communication is established. If sound is delivered, voice communication is possible, and if light is delivered, light communication is possible. In the same way, if radio waves are delivered, we can communicate wirelessly.

There are few ordinary people who are allowed to communicate by radio waves on their own. Radio waves are controlled by the government, so you can't send them out without permission. However, there is one radio that the general public is allowed to use for their own interest and training.

That is "amateur radio.

Radio waves are also a precious resource, so this is really a "special permission", but the world of radio waves has always been opened up by amateurs, and amateur radio has a high status in this world, and is internationally protected and respected (although it is often troubled by broadcasts from countries that do not follow international rules, and by radio waves for military purposes). It's an internationally protected radio. It is commonly used all over the world.

Amateur radio requires two licenses, one for the individual, the "Amateur Radio Engineer License", and the other for the radio equipment, the "Radio Station License". However, in the Radio Law, there is a clause that says that instead of letting people use the radio for fun, they should contribute to society by making "emergency communications" in times of disaster or when other means of communication such as wires are not available. All the laws are made to fulfill the purpose of "promotion of public welfare", that is, "everyone is happy", so the Radio Law also makes amateur radio stations contribute not only to themselves but also to society, so that everyone is happy.

Therefore, the use of Amateur Radio as a means of communication in times of disaster is allowed when other means of communication are not available, or rather, we are told to be proactive and show our volunteer spirit. (To put it bluntly, setting up an amateur station for emergency communication is not allowed because it is not for the purpose. (To put it bluntly, opening an amateur station for emergency communication is not allowed because it is not the purpose of the station. If you are not interested in radio, you should not set up a station for communication or in case of disaster. (However, this is a vague definition, so anyone can open a radio station with any real intention.)

The most common news I heard this year was, "Fat people have evacuated to Fat Elementary School, but we still can't contact them. I guess they don't have telephone or electricity.

I guess there is no phone service or electricity. Cell phone base stations were also down. If it's a typhoon, we can't even check from a helicopter.

There is no communication at all. In this day and age. This has happened many times this year, here and there.

Because we only have advanced means of communication, we are vulnerable to the opposite.

What would have happened if that school had an amateur radio club?

The power supply is a problem, but if the school has a mobile operation, the batteries are probably charged on a regular basis. It is possible to operate for a while. It can also be operated with batteries. If you have a generator, you can communicate as long as there is fuel. If you have a power supply from your car, you can communicate as long as your car has fuel. If you don't need a strong signal, a small solar panel and a rechargeable battery will be enough.

Schools need to have amateur radio equipment.

It would be nice to have an amateur radio club.

If you have equipment that can operate in the shortwave band, you can contact people all over the country. This is surprisingly important.

In the Great East Japan Earthquake, the entire region was extensively damaged, and there was no way to get information from the surrounding areas or from each other. The next door neighbor was also a disaster area. There was no way to find them except by foot. There is no electricity and no means of communication in the area, so it is impossible to know what is going on in the whole of Japan from the field.

What can be done in such a situation is to support the transmission and relay of information by areas outside the disaster area where the infrastructure is fully functional.

At that time, the personfinder system for safety confirmation was very active on the Internet. Many people in the non-affected areas volunteered to read the letters from the photos in the list of evacuation centers and manually input them into the system. This is an example of people from areas with living infrastructure supporting the disaster area from afar. (It all started when one person first started taking pictures of the list of evacuation centers with his cell phone and uploading them to the Internet.) ) Since government agencies are too busy to do such work in times of disaster, each and every Net user across the country showed their volunteer spirit and voluntarily participated in the creation of the Person Finder list.

At that time, it was almost always possible to communicate with the affected areas through the shortwave band using amateur radio. There were many stations that contributed to the communication. In particular, stations in the Kansai region worked diligently, and later collaborated with Tokyo and other cities to operate in accordance with the changing radio wave conditions at different times of the day.

Although there were still some issues to be resolved, I think it was very worthy of recognition. (Not that it matters, but there is a way to memorize the Japanese telegraphic character "o" by combining the words "toto toto" and "omo kokoro". Let's take this opportunity to memorize one character.)

I can't hear it here in Tokyo, but I'm sure it was very active on the 144 MHz band in the area.

So, it would be very reassuring if schools, which could be evacuation centers, had amateur radio clubs and practiced emergency operations.

Nowadays, people say, "Why use a radio when we have cell phones? However, the purpose of amateur radio is not to be able to talk, but to be able to receive radio waves and communicate, and to enjoy the hobby of self-powered communication itself.

Cell phones can't connect in times of disaster, but amateur radio can. And the world. There is a big difference in these situations.

Now, it is true that having an amateur radio club at school is a good thing, but there is a big challenge in establishing and maintaining it.

In order to establish and maintain a club station, it is necessary to have a licensed radio amateur at all times. In a school where students (and teachers?) change every year. In schools where students (and teachers?) change from year to year, this is a challenge. The exam is not difficult, but you can't force people who are not interested to take it. It used to be that some of the boys who were interested in radio and electronics took up amateur radio, and there were usually a few in the school year, but now the troll net of video games and computers has swept away all the boys, and almost no one gets into amateur radio anymore. Also, there were many people who got into amateur radio because it seemed convenient, but now that we have cell phones, almost no one has that motivation. Talking to strangers all over the world, which was once considered a wonderful thing, now has a bad image due to internet crimes, and parents are wary of it. As a result, clubs have been disappearing from schools. When I was young and started radio, there was a radio club in a famous girls' high school, and it was very popular in the radio world, as valuable as communication with the Showa Station in Antarctica. But I think I have a solution.

But I think there is a solution. (This is just a rant from here.)

At the time of the Great East Japan Earthquake, JARL collected radios for the disaster area from many individuals, and assigned a call sign to each device to be used by communication supporters in the disaster area. The call signs were given to each piece of equipment and sent to the communication supporters (radio amateurs who support the communication as volunteers). Originally, a call sign was given to the user and the machine as a set, but this way, the call sign was limited to this person and this radio, which was inconvenient. At this time, JARL itself became the licensee and made it available to anyone who supported communications. 8J A total of 300 radios were sent to the area by quickly assigning call signs starting with 1.

http://www.jarl.or.jp/Eastern_Japan_earthquake.htm

This was a good idea.

In the same way, JARL will act as a licensee to open and maintain radio facilities in elementary and junior high schools for those schools that wish to use them. The local JARL members and local amateur radio clubs could support the operation. This would make it possible to open a station for a long time, if not permanently. Even if none of the students have a license at one time, we can continue with the help of the local community.

Radio equipment and antennas would be provided by local radio operators. Elementary school students are taught to run away if approached by a stranger. Even if they live in the neighborhood, they are treated as suspicious if an adult steps into their school. It is precisely in times like these that we need to deepen the ties between the community and the school. Wouldn't it be nice to have a neighborhood radio guy come to the school radio club once in a while and teach the students how to communicate and build antennas?

Wouldn't it be great to have such an idea? I'd like to help with that.

On a different note, amateur radio stations with big antennas are not suspicious, but they are the most reliable means of communication in case of emergency. Amateur radio cars with big antennas are actually the best all-in-one radio stations for disasters, and they can contribute to society the most.

And yet, citizens call 110 to report suspicious cars parked in the area, and the police even stop the cars in motion to question them. I'm going to go to the police first, so can you give me a registration sticker after you check it out? A sticker that doesn't question people when they see the antenna. (laughs)

There is one bright news. I heard that the number of people trying to get an amateur radio license is increasing this year. The main reason for this is disasters such as earthquakes, tsunamis and typhoons. This is probably due to the experience of having no means of communication. Another factor may be the increase in the number of people hiking in the mountains. There is no cell phone connection in the mountains. What's different from your original interest in radio? But if it's fun to try, I'd like people to enjoy it, and I think it's good to have various opportunities, so I'd like many people to get their licenses.

こんなペンがありました。


ペン先から照明が。これなら暗闇でもメモがとれます。移動運用でログも書けますね。

先日書いたスケートの話の中で、スキーとスケートは真逆の技術だと書きました。放っておくと加速してしまうスキーと、放っておくと止まってしまうスケートの技術の差です。他にもスキーはカービングになってかなり両足荷重に近くなったけど、根底には外足荷重。外足のインエッジが重要。スケートは内足のアウトエッジをかなり使い100%乗ることも多々あります。
この逆だと言う話、先日のオリンピック、ジャンプ団体のゲストに出ていた、スケーターの高橋成海さんが、スキーは選手引退まで一切やらなかった（やらせてもらえなかった）けど、やってみたらスキーは止まる技術、前閉じハの字でスケートと逆だし、スケートは踵荷重だけどスキーは前の方。何もかも逆でビックリ、と、私の言いたかったことをよくぞ話してくれました。
嬉しかったなぁ。
さてスキーのターンは斜面上でもあり、下に移動しつつでありますが、円錐形の回転運動なので、移動する円錐の頂点を中心に遠心力をエッジで受け止めることになります。
ターン後半は落ちる力をターンが受け止めるので、遠心力+ブレーキ力も受けます。そして次のターンに入ったとき、落下運動の無重力を楽しむだけでなく、円錐頂点を中心とした遠心力をしっかり受け止める事が出来れば、雪を斜面斜め上に弾き飛ばすシュプールが描けます。
多くの中級以下のスキーヤーは雪を斜面下方向にしか飛ばせません。減速技術だけだからです。ターン後半ばかりで前半が短い。もっと円運動を楽しんで、前半も半分ある、雪を上に飛ばすターンを目指しましょう。しっかり切り上げてから次のターンにパッと切り替える。（前のターンの円錐形から次のターンの円錐形に移る。）切り替えてしばらくは真下に向かうターン、ここは落下に任せて加速しつつ遠心力をエッジで受ける。真下以降はターンを続けることで減速も兼ねる。そんなイメージで滑ればう上級者です。

アマチュア無線にもデジタルモードが搭載される昨今、これ、皆さんありがたいと思うほどの機能だと実感ありますか。
D-STARやWIRES-X、ネットワークを介した通信に一定の価値はあるけれど、どれだけの人が楽しんでいるか。
やってみても、出来た、と言う喜びはあっても、なんかねぇ、ですよね。どちらの世界にも、なんかうるさい方が張ってますよね。居心地悪いし。オペレートも聞いててイライラする場面多いし。
いい無線機買えば漏れなく付いてきてしまうこの機能、VO-IPしたければ必要かもしれないがしたくなければ要りませんね。
ではせっかく付いているのならと、シンプルにデジタル同士の通信はいかがでしょう。モービル同士とかやってみましたか。はい、走行中は全く使い物になりません。FMモードならまだまだ話せるのにデジタルは簡単に復調できなくなります。復調できなくなってFMに戻して～とデジタルで伝えてももう伝わらない。仕方ないからアナログレピーターで改めて伝えると言うバカらしさ。
ほぼすべての新型トランシーバーにこんな使えないモード載せて１万２万高くなるの、なんか解せないですね。積んでも積まなくても部品代としては大差無いのかも知れないけど。
それをやってみたい人がそこにお金をかけて楽しむのは全然いいけど、そうではない人にもみんな持たせてお金取る、みたいに思えちゃいます。
警察や消防がデジタルに移行しましたが、あちらは強力なエラー補正機能があるようですが、それでもアナログにはかなり劣るようで、恐らく相当業務に支障が出ていることでしょう。使えない基幹系デジタルに業を煮やし、消防の現場ではアナログの署活系の使用頻度が増えたとか増えないとか。デジタルモード、命のかかっている業務で使うべき技術ではない。混信にもめちゃ弱い。自分達がデジタル使ってみて思う率直な感想です。
そうしてみるとスマホは大したものです。ほとんど支障は感じない。音もきれいになりました。デジタルなのに。デジタルだから音もきれい、とも言えるのでしょうが、われわれのトランシーバーのデジタルの音の悪さ、酷いもんですよね。誰だか声で判別できないくらいですから（以前よりマシにはなってきてますが）。携帯電話はよほどお金をかけて、それこそ見える範囲に基地局いっぱい整備したのでしょう。それが出来ないのならアナログの方が音声通信では遥かに優位だなぁと思うわけです。
特小トランシーバーで100km超えの通信が可能なのはアナログのFMだからです。
アマチュアは進歩的であれ、とは言え、デジタル化は我々が望んだものではありません。
ID-52、アナログ機でIC-52出してくれよ。２万円安く。デジタル要らないから。10倍売れますよね。どうしてダイヤルの無いIC-2Nが席巻したか思い出して欲しい。必要な機能があって、安くて、性能がいいから売れたんです。
私自身、WIRESXもD-STARも出ますけどね。すべての無線機には要らないってことです。それより安くしてよって。かつてのAQSやDCS?機能みたいな感じですね。

「みんな５ワットコンテスト」って言うのをやってみたい。
1200MHzって、どんなにお金があっても資格があっても10W、移動局は1W、と、なかなか平等性が高いなぁと思ったのが発端。
あの巨大パワーひしめく7MHzだって、5Wでも結構届くんだよ。（実際フロアーノイズや通信以外のいろんな電波飛び交っていて、それを上回らないといけないから、5Wは厳しいのは事実だけど。）それを皆で楽しめる、公平で平等なコンテストをやってみたら面白いと思う。
コンテストを主催するのは大変で、審査だとか集計だとかいろいろある。あるコンテストなんてよほど大変なのか、翌年開催直前まで結果発表がないところもある。
でも競技会とは少し離れて、趣味の世界のお祭り的に考えたら、自己申告を発表しあって順位を決めれば十分だろう。
Googleフォームって知ってると思うけど、ここに各自自己申告の成績を入力するだけで、スプレッドシート（エクセルの表みたいの）が完成する。そのシートを得点順に並び替えて公開すれば順位表になる。
審査も表彰も景品も無し。ただそれを楽しむのなら、主催者も楽だ。
このやり方で果たして出来るか。ちょっと仲間内で試してみようかな。

関東UHFコンテストは自宅から。

少しだけ参加しました。

1200MHzと430MHz。

1200MHzは聞こえる局は呼んで、CQ出さず。

開始して少しっ経った頃と、終了間際だけ。

ちょっと顔を出しただけです。

1200のいいところは、移動局は1W、固定局が出しても10Wというところ。全員がね。
どのコンテストも10W制限でやったらいいのになぁ。と考えさせられます。

430はと言うとこのような賑わいです。

関東地方の430は凄いでしょ。コンテスト時は山の上からだと出るところが見つかりませんから。
