Online HF prediction tools, tailored for Utility DXing

Recently I bumped into the relaunched web pages of the highly esteemed HF Prediction pages of Space Weather Services from the Australian Bureau of Metereology : 

http://www.sws.bom.gov.au/HF_Systems

On their sub-page "Internet Tools" they offer some excellent tools for HF propagation prediction which seemed to be tailored just to the needs of us listeners.

I wrote a short PDF (7 pages, 22 illustrations) about that, giving some examples. This paper also deals with multipath propagation, degrading even strong digital signals plus FAX. Among the Aussies' web page you will find a set of tools under "Digital HF Prediction", dealing perfectly with just this challenge.

Guangzhou Coast Radio Station coverage expands to Huangyan Islands

GUANGZHOU, Feb. 1 (Xinhua) -- Guangzhou Coast Radio Station in south China's Guangdong Province launched a trial service to deliver maritime information that covers Xisha Islands, Zhongsha Islands and Huangyan Islands on Sunday.

According to the Navigation Guarantee Center of South China Sea, which is affiliated with the country's Ministry of Transport, the station will broadcast navigational and meteorological warnings and forecasts in English six times a day, with a radio coverage of around 500 sea miles.

As one of the five Navtex radio stations in China, the Guangzhou Coast Radio Station is in charge of broadcasting maritime safety information to waters that include the areas south of the Taiwan Strait and the South China Sea.

Navtex (Navigational Telex) is an international automated system for distributing navigational warnings, weather forecasts and rescue notices to ships. It is also a component of the Global Maritime Distress and Safety System.

Beethoven and numbers on Korean shortwave

Dec 9 (Reuters) - As a scratchy rendition of Beethoven's Piano Sonata No 8 fades into a sea of shortwave radio static, a robotic female voice starts speaking in Korean. "Number 1913, number 1913, incoming message," the voice says, before reading out seemingly random sets of numbers.
