The first time I visit Japan & work on HF band with JOS/JCS were on 1980, a Japanese company chartered our ship loading oilrig pipes from Tokai/Hirohata/Tokushima towards USA...😄 Every 2 days we need to send MSG through JOS/JCS towards the charterers' office to report our ship's position, sailing speed, bunker/water consumption, and ETA!
I understand that you were on board as a radio operator on the route from Japan to the United States. I think it was difficult to communicate via shortwave. Thank you for your valuable information. I would like to go to the JOS site, but I don't have a chance to go to Nagasaki from where I live.
@@muyorekomaru As I know on 1960-1990, the most powerful short wave station able to cover communications all over the North Pacific Ocean are JOS/JCS/KPH. KPH is located at San Francisco. Even the ship position close to the west coast of USA, it's still easy to send message towards JOS/JCS😁 On my sea life, the longest distance on short wave by Morse are Hawaii to Norway on 25Mhz band during day time, and Indian Ocean to UK on 12Mhz Band at night time！Both working smoothly 🤗
Hawaii to Norway Indian Ocean to UK, That's quite a long distance ! Is the output 1KW? Since it is a long wire at sea, I wonder if the radio waves will send pretty far away.
@@muyorekomaru The ocean-going ship which built on mid 1970 all equipped with HF transmitter upto 1.5Kw, MF transmitter upto 0.5Kw, and 50w on VHF transceiver ! These are the maximum output of ship's transmitter restricted worldwide by rules and regulations! Even the 25 years old ship(built on 1957) I worked on 1982, the radio room already give-up the old German transmitter and installed a new Redifon1.5Kw HF transmitter, and the main receiver also replaced by a digital Drake! For long range communications, sea surface has a much better reflect of HF radio waves... Just remember 2 case should let you know and feel proud of Japan! 1. At 196X-198X Japan are the only Asia country which provide weather chart through radio FAX(JMC) for flights and mariners! 2, The station "H" (total only 8 worldwide) of an old positioning system named OMEGA (working on low frequency) for ships and sub-marine*** was located at Japan, it's the only one in Asia area! JRC also built the OMEGA system receiver, I am luckily to see this expensive toys on my first ship
I see, because of the high output and the location on the ocean, the radio waves send pretty far away. Omega Station in Tsushima is now a memorial park. It was the tallest building in Japan until the Sky Tree was built.I would like to visit someday. Thank you for your always exciting stories !
修学旅行で長崎無線局を見学しました。何人もの先輩が従事していたからです。
コメントありがとうございます。それは貴重な見学でしたね。銚子、長崎と言えば憧れの職場でした。
昭和時代おじが船医をやってました。そのおじの娘さんが通信士と結婚しました。
コメントありがとうございます。船医さんが乗船していた頃もありましたね！船医さんの娘さんと通信士の結婚なんて今ではあり得ない貴重なことですね！

お褒めの言葉ありがとうございます。当時をご存知の方から褒められるのが最高に嬉しいです！。大変なお仕事を後世に継承できればなと思っています。皆さんのご意見を頂きながら再現しています。ブラッシュアップしていきますので、いろいろご指摘お願いします。
こんにちは、拝見しました。よくできていますね。出来たら肩章は実際らしくするため一等航海士のものより通信長のものに合わせられたほうが良いかと？
コメントありがとうございます。おっしゃるとおりですね、航海士は黒色、機関士は紫色、通信士は緑色とお聞きしました。ばったもんですいません、なかなか手に入りません。
こんばんは、たぶん今でも神戸の「アリマ」で手に入ると思います。
貴重な情報をありがとうございます。
