1827Royal NavyWhen Frederick William Beechie, who leads the Blossom, landed from the current port of Futami, Chichijima, he encountered two crew members of the British whaler William, who had disappeared the previous year, and ships from other countries were also arriving. Beechie left the island by hitting a territorial declaration board against a tree on the island.Residents who received a report from the beach about the existence of the Ogasawara IslandsHonoluluThe British Consul is proceeding with a settlement plan for the Bonin Islands,1830A settling group consisting of 5 Westerners and 25 from the Pacific Islands was formed and settled in the present Chichijima.After this, vessels from each country frequently called at the Ogasawara Islands for various purposes, such as securing water and food and disembarking the sick.

In August 1863 (May 8rd year of Bunkyu), the shogunate ordered the island to retreat under the pressure of the Western powers.In December 3 after the Meiji Restoration, the Meiji government reclaimed the Ogasawara Islands.[44]

American Radio Relay League Issued by (ARRL)DXCCTo sayAwardIn JapanMinamitorishima, Ogasawara Islands other than Minamitorishima, and divided into three entities other than Ogasawara Islands. MinamitorishimaIs far from other land and is considered a separate entity.The Ogasawara Islands other than Minamitorishima have the shortest distance to mainland Japan at 177.Miles Although it does not meet the distance regulation of 225 miles or more, due to administrative treatment, when returning to Japan,Ogasawara uses a different callsign from the mainland", Depending on the conditionJapan Amateur Radio Federation Ministry of PostBy negotiating with and designating the call sign of the JD1 prefix, it became a country different from the mainland (the name at that time, renamed in 1998).In addition, it should be noted.QST(ARRLMagazineAccording to the country list of the March 1949 issue, the call sign before returning to Japan was KG3IA-IZ in the United States (Trust Territory of the Pacific Islands(Part of) was specified. 1972OkinawaOkinawa Prefecture is treated as the same entity as the mainland because the call sign like Ogasawara was not specified when returning to the mainland of Japan (Okinawa before the return was KR6 (US military relations) and KR8 (Ryukyu people)) ..

In addition,TelAs described in the section, in the past, a considerable number of islanders were open due to the fact that it was very difficult to make a wired telephone connection to the mainland and it was difficult to make a call between Chichijima and Hahajima. The number has decreased due to improvements in telephone lines.Most of the islanders who had opened the station simply used amateur radio as a means of daily communication, and as of March 2014, 3, Chichijima and Hahajima (in Ogasawara Village, residents can be registered as residents of Hahajima) are operating outside the island.・ Even if you can hear JD31 amateur stations, most of the operations are by travelers.

Satellite relay line for difficult viewing

1996FromTokyoThe operation of "satellite relay line for measures against poor viewing" has started.

Desk rumble) and the above tableUHFAfter converting to waves, it was retransmitted as UHF waves from the transmission station (existing Chichijima and Hahajima relay stations).Furthermore, in some areas, due to co-listening reception, the channels were changed so that the channels would be arranged in the same way as the Tokyo Tower main station (however, TBS 4ch, TOKYO MX 5ch, and NTV 6ch. NHK-BS is above. Same as table).

The reason for scrambling and digital compression was to prevent satellite line radio waves from being intercepted and watched outside the Ogasawara area (mainland, neighboring countries, etc.) (for terrestrial television stations).Broadcast licenseBy prefecture, orKanto wide areaEtc. on a regional basisBroadcast target areaIs stipulated, and if NHK / commercial TV broadcasts in Tokyo, which do not have a national or foreign broadcast license, can be received in other areas, legal problems will arise).The scramble method is a unique method called "Ogasawara method", and a decoder that decodes it was not available to the general public.In addition, the use of satellite lines costs an enormous amount of 4 million yen per year, and 3,000 yen is collected monthly from the islanders as a "television broadcast reception fee" for viewing this broadcast, and NHK and commercial broadcasters in Tokyo also pay the cost. Was there.in spite of,MicrowaveThe satellite line using is vulnerable to weather changes,(I.e.In such a case, a reception failure occurred.

Terrestrial digital TV broadcastingTransition to

Conventional terrestrial television broadcasting (analog television broadcasting)2011It was decided that it would end in July, but for the subsequent reception of terrestrial digital television broadcasting in the Ogasawara Islands, both plans via satellite lines and submarine optical fiber cables were being considered.Eventually, along with the communication business such as the Internet, the Tokyo Metropolitan Government will take the lead in developing the information infrastructure, and the transmission of terrestrial digital broadcasting to Ogasawara will be via a submarine cable called the "integrated information infrastructure optical cable." Will be done[55]..According to media reports at the time2009It was reported that the contractor was selected and the construction order was placed within the company, and the maintenance will be completed by the end of terrestrial analog broadcasting in July 2011.[56].

Broadcast transmission by integrated information infrastructure optical cable is first in HachijojimaHachijo relay stationIs received on the same island and transmitted from there to Chichijima and Hahajima by submarine cable.[Annotation 5]For transmission within Chichijima and Hahajima, the existing Ogasawara village optical fiber cable was used instead of the new digital relay station, which requires a huge budget and construction period.[57].

Prior to its maintenance, from March 2010Terrestrial digital broadcasting (BS safety net / standard definition broadcasting)Started the main broadcast, and Ogasawara Village was included in the target area.Along with that, the same yearMay 6, The transmission of analog TV broadcasting by the old satellite line has ended.However, both Chichijima and Hahajima TV relay stations have survived as terrestrial analog TV relay stations that transmit two waves of NHK-BS and a total of three waves of TOKYO MX, which was not covered by BS safety net broadcasting (Of these, TOKYO MX was broadcasting a TV program sent by sea from the mainland for a full day with a delay of 3 weeks until the start of the test broadcast of terrestrial digital broadcasting by submarine cable.[Source required]).

August 2011, 5,Ogasawara Village Cable TVThe test broadcast of terrestrial digital broadcasting (high-definition image quality) of each station in Tokyo was started, and the village was excluded from the target area of ​​BS safety net broadcasting.On July 7, the same year, both the Chichijima and Hahajima relay stations were closed on the end date of terrestrial analog television broadcasting, and were diverted as radio relay stations as described below.

Due to the above circumstances, there are currently no relay stations in the Ogasawara Islands that transmit radio waves for terrestrial digital television broadcasting.
