This Shortwave Station’s Transmitter Site Sits Pretty in the Tropics (Radio World)

KTWR’s home is on Guam, which makes for some interesting broadcasting

If you’re an avid Radio World reader, you know that we love to highlight unique radio facilities, whether they be local or abroad. If you happen to love that sort of content, you’re in luck!

Broadcasting since 1954, Trans World Radio, or TWR, is a Christian radio distributor that collaborates with U.S.-based radio stations to spread the gospel via local FMs, mediumwave or high-powered AMs and shortwave transmitters.

According to its website, TWR’s programming is broadcast in 200-plus languages on air, online and on the ground in 190 countries. It is celebrating its 70th anniversary this month.

With such an extensive résumé, TWR was bound to have at least a few unique transmitter sites. One such site that we’ll share with you here can be found “Where America’s Day Begins,” floating just above the equator in the western Pacific Ocean.

In Micronesia, TWR’s shortwave member station on Guam, KTWR, serves listeners across most of Asia, spanning Siberia to India to Indonesia. [Continue reading…]

Radio Poland marks 88 years on air (Polskie Radio)

Radio Poland is celebrating its 88th anniversary on the air.

The station, launched on March 1, 1936, is part of Poland’s public radio network.

It broadcasts programmes on developments at home and abroad, Polish foreign policy, the economy, business and foreign investment.

Radio Poland, also known as Polish Radio’s External Service (Polskie Radio dla Zagranicy), aims to provide objective and impartial information about Poland and the country’s stance on international affairs.

It reports on developments in Polish society, its daily life as well as scientific and cultural achievements.

The website, part of Radio Poland, is a leading English-language resource for Polish news.

Updated regularly all day, every day, the website covers domestic and foreign affairs, economy and business, culture, sports and human interest stories.

Polish Radio launched shortwave broadcasts in English and Polish in 1936. They were discontinued with the outbreak of World War II in 1939.

After the end of the war in 1945, the shortwave channel Warszawa III resumed external broadcasts.

In 1990, Polish Radio started broadcasting in Ukrainian, Belarusian, Lithuanian, Czech and Slovak.

Then in 1994 the External Service began daily broadcasts in several languages via the World Radio Network.

A Laptop and MixW software give Carlos cleaner Radiofax imaging

Many thanks to SWLing Post contributor, Carlos Latuff, who writes:

Now I’ve a notebook computer, and I can decode the Kyodo News radiofax signal accurately.

Unfortunately, unlike Fldigi, the MixW software doesn’t have the option to save the image, which forces me to make print screens, paste them into a graphics program and save them as an image. Still, the result is perfect (see image above].

Attached the NX Japan Navigational Warnings, with translation done by the Google Translator app.

For documentation purposes, I saved the decoding in vídeo:

Wow, Carlos! It does make a huge difference when you’re not relying on acoustic coupling for the decodes. Obviously MixW is a very capable Radiofax decoding system as well. I’m surprised it can’t automatically save images, though. Thank you for sharing!

Carlos notes,

“One thing is certain. Anyone who follows Kyodo News via radiofax and, especially, the navigational warnings, never dies of boredom!”

No kidding, Carlos. That’s scary stuff for those making way through the Gulf of Aden.

Thank you for sharing!
