共軍和台戰機對話為何曝光 陸媒驚爆這一原因!

共軍轟-6等多架戰機7日逼近我防空識別區,有無線電玩家疑錄到雙方對話內容,共軍飛行員嗆「請立即離開,否則一切後果自負。」陸媒驚爆,從台灣無線電玩家監聽到的對話來看,共軍飛機離台灣已經很近!

很多人可能會感到奇怪,共軍空軍戰機飛行員與台灣戰機飛行員之間的無線電通話,怎會被台灣的民眾聽到,軍用無線電信號不是應加密嗎?甚至有陰謀論稱有人在背後搞鬼。其實,這是誤解。

據新浪軍事報導,北國防務指出,共軍空軍戰機飛行員與台灣戰機飛行員之間的無線電通話,採用的是國際民用航空公約所規定的國際航空應急頻率121.5MHz,這是一個無加密的公用頻道。

121.5MHz主要是用於遇險或處於危機狀態的航空器,與地面電台之間的通訊聯繫,不僅所有民用航空器都配有國際航空應急頻率的通訊設備,軍用飛機也可使用這一頻率。而此次事件,兩岸戰機的飛行員不可能透過各自加密的通訊頻段通話。最好的選擇,也是目前通行的慣例,就是透過121.5MHz這一公共頻段進行通話。因此,台灣的民眾可以透過無線電信號接收設備,收聽到雙方戰機飛行員之間的通話。

一般來說,這些設備的接收距離可以達數十公里甚至上百公里。而從台灣無線電玩家可以監聽到兩岸戰機的對話來看,共軍飛機其實離台灣已經很近!該次共軍空軍戰機飛行員怒嗆台灣的戰機飛行員,態度強硬,也讓台灣的綠營徹底明白妄想「以武拒統、以拖拒統」,只是死路一條。

神祕浩帆6號助朝 多次來台

神祕浩帆6號助朝 多次來台

根據船舶追蹤服務網站「MarineTraffic」數據,「浩帆6號」(翻攝自CNN網站畫面)2014年至2016年多次駛抵台北港、台中港和高雄港。(MarineTraffic網站畫面)
 中國時報

/綜合報導

根據船舶追蹤服務網站「MarineTraffic」數據,與北韓政權有曖昧關係的香港貨船「浩帆6號」(Hao Fan 6,譯音,有報導稱該船懸掛加勒比海國家聖克里斯多福及尼維斯旗幟),2016月6日2日曾到過台中港。美國有線電視新聞網(CNN)指出,「浩帆6號」當時若替北韓私運煤炭,恐違反聯合國安理會同年3月頒布的新禁令。

曾經消失逾1個多月

CNN報導,聯合國10月10日以違反北韓制裁案為由,禁止「浩帆6號」等4艘大型貨船進入全球任何港口。根據「MarineTraffic」,聯合國發布禁令時,「浩帆6號」正在南韓南方海域,但隔日早上11點17分後就失去訊號,神秘消失了1個多月,才又出現在東海一帶。

根據國際海事組織(IMO)規定,每艘大型船隻都必須安裝船舶自動辨識系統(Automatic Identification System,AIS),但船上人員若關閉系統便能躲過監測,重新開啟時,追蹤數據則會出現異常。專家表示,跟北韓有關的船隻在從事不法行為時,通常都會這麼做。

根據「MarineTraffic」,「浩帆6號」2016年曾3度造訪北韓,並活躍於運送煤炭的航線上,9月時有兩次訊號出現在北韓的港口城市南浦,10月曾出現在中國山東省的煤炭出口港嵐山港,接著又回到南浦。

最近一次在去年6月

該網站可蒐集「浩帆6號」從2014年1月1日至今年11月14日的所有位置資訊,點入追蹤數據可見,這艘貨船曾經多次往返台灣等多個港口,包括台北港、台中港和高雄港,最近一次是2016年6月2日駛抵台中港。

CNN指出,「浩帆6號」若替北韓私運煤炭,恐違反聯合國安理會的制裁案。安理會2016年3月宣布禁止北韓出口煤炭、鐵和鐵礦砂,惟營收不會助益平壤核計畫者除外。北韓同年8月發射兩枚洲際彈道飛彈後,安理會全面禁北韓煤炭、鐵和鐵礦砂出口。

根據CNN調查,「浩汎6號」長約140公尺、可裝載8343噸貨物,其船東是「香港新旺有限公司」(Trendy Sunshine Hong Kong Limited)。不過,該公司在香港的註冊住址,使用者卻是「駿業國際」(SBC International),此舉雖未違反香港法令,卻增添不少想像空間。

Corporation. ANS publishes news related to Amateur Radio in Space
including reports on the activities of a worldwide group of Amateur
Radio operators who share an active interest in designing, building,
launching and communicating through analog and digital Amateur Radio
satellites.

The news feed on http://www.amsat.org publishes news of Amateur
Radio in Space as soon as our volunteers can post it.

Please send any amateur satellite news or reports to:
ans-editor at amsat.org.

ISS Global Testing SSTV December 5-6 Prior to MAI-75 Over Moscow

http://ariss-sstv.blogspot.com/ published an update to the
December MAI-75 SSTV testing schedule:

**UPDATE – Nov 28**
Seems the system will be put through some extended testing from
December 5 starting around 15:00 UTC and running until 09:00 UTC
on December 6. Test images will be used during this period. This
will provide near global coverage if all works well.

The MAI-75 schedule over Moscow remains unchanged at this point.
The times correlate to a small number of passes each day in range
of Moscow.

Dec 6, 2017
Setup and power on –  13:40-14:20 UTC
Power off – 17:05-17:15 UTC

Dec 7, 2017
Power on –  13:45-13:55 UTC
Power off – 17:30-17:40 UTC

Dec 8, 2017
Power on –  14:05-14:15 UTC

Power off and stow – 17:00-17:10 UTC

Soyuz Launch Anomaly Results in Loss of D-Star ONE Cubesat

A new Russian weather observatory and the first prototype for Telesat’s planned
network of 100-plus broadband communications satellites in low Earth orbit were
among 19 spacecraft lost after a Fregat rocket stage ran into trouble soon after
liftoff aboard a Soyuz booster Tuesday.

The Fregat rocket pack was supposed to place the 19 satellites into four
different orbits Tuesday in a four-hour flight sequence following launch on a
Soyuz rocket from the Vostochny Cosmodrome, a new spaceport in the Amur region
of Russia’s Far East.

A report published by Russia’s Interfax news agency Tuesday quoted a Russian
space industry source who attributed the apparent failure to human error. The
source said a mistake uploaded to the Fregat’s flight computer caused the upper
stage to be in the wrong orientation for the main engine’s first burn, which was
scheduled to last 77 seconds to reach a temporary parking orbit a few hundred
miles above Earth.

Billed as the first German commercial CubeSat, the D-Star One spacecraft had
four communications modules on-board, two of which were to be used by the
amateur radio community. Developed by German Orbital Systems in Berlin in
cooperation with the Czech company iSky Technology, officials hope to build
follow-on satellites to construct a low Earth orbit communications network.

AMSAT-SM Supports ARISS With New Donation

AMSAT-SM is proud to announce a donation to ARISS (via AMSAT-NA) of
$285. We hope that this small donation will help ARISS further work
with amateur radio from ISS.

AMSAT-SM is the Swedish section of AMSAT with approximately 220 members. One of
their objectives is to inform Swedish hams about the fun with amateur
satellites! Not many SM hams are active via satellite at the moment. With the
help from our Swedish webpage and HF-net we hope that more Swedish hams should
be using amateur satellites. The AMSAT-SM annual meeting is held every spring.
Some weeks on Sundays we have a HF-net on 80 meters with lots of news about
satellites and space.

IARU Frequency Coordination for China’s Juvenile 3U Cubesats

The IARU Amateur Satellite Frequency Coordination Status pages,
hosted by AMSAT-UK as a service to the world wide Amateur Satel-
lite Community, report on an updated coordination for the Juvenile
project from China.

Juvenile is a 3U CubeSat project led by China Soong Ching Ling
Youth Science and Culture Center for school education and amateur
radio.

The amateur radio station onboard will provide telecommand, tele-
metry and FM repeater functions:

1. A VHF uplink and UHF downlink data control board with loop
back function, which can act as an FM repeater.

2. A VHF uplink and UHF downlink 9k6 BPSK data control back up
board, with a trigger to take a photo from a camera, and
transmit SSTV image through NBFM modulation.

3. A 2.4 GHz band with 2 MHZ bandwidth multiple frequency up
and down link communication experiment.

Planning a launch from Jiuquan Space Center into a 500km Sun
Synchronous Orbit.

The IARU reports a November 30 revised coordination has been
provided.

Frequency coordination for Juvenile 1B, 1D and 1F
Uplink     435.290 MHz FM
Downlink   145.840 MHz FM
Telemetry  145.930 MHz 9K6 BPSK

Frequency coordination for Juvenile 1A, 1C, 1E and 1G
