R.Australia文字放送受信

予告通りRadio Australiaの文字放送が受信できた。放送中の番組を途中で切り、0830からは無変調のキャリアーとなり、0831からFSKの電波が出てきた。
この放送はあらかじめ音声録音して後から幾度でも復調が可能だ。復調ソフトは無料のものが数多くサイト上にありどれでも基本的なことは変わらないようだ。

開始が遅れたことから最後の画像は送られなかった。MFSK16と32モードで以下のテキストが復調できた。
This is Radio Australia transmitting in the MFSK16 digital text
mode. MFSK16 has a speed of about 58 words per minute.

Digital text via an analogue shortwave broadcast transmitter
provides an opportunity for content to be received in challenging
reception conditions, when voice broadcasts may be difficult to
understand.

Please send reception reports, if possible with screenshots and
audio samples, to Holmes.Nigel@abc.net.au.

Next from Radio Australia, digital text in the MFSK32 mode.

This is Radio Australia transmitting in the MFSK32 digital text
mode. MFSK32 has a speed of about 120 words per minute.

With a focus on Asia and the Pacific, Radio Australia offers an
Australian perspective. Our content on radio, web, mobile and
through social media encourages conversation and the sharing of
ideas between Australians and the diverse people and cultures of
the Asia Pacific.

As the international radio and online service of the Australian
Broadcasting Corporation (ABC,) Radio Australia has a rich
history as a producer of content that is educational, informative
and entertaining and that serves to expand horizons, shape
opinions and broaden regional views on topical issues.

Our content explains Australian culture and society and includes
news and analysis, English Language Learning and information
about Australia.

Please send reports on reception of this digital text
transmission to Holmes.Nigel@abc.net.au. If possible,
screenshots and audio samples would also be
appreciated.



この後1230からも行われる予定。周波数は12065と9580kHz、リリースでは12095となっているが多分Australiaが使っている12065kHzではないかと。
