International Broadcast Radio Schedules and Frequencies
International broadcasting remains a vital medium for global communication, allowing listeners to tune into diverse perspectives and cultures across borders. By utilizing different bands of the radio spectrum, stations can transmit signals over vast distances, reaching listeners in various geographic zones.
Radio enthusiasts typically monitor two primary bands: Medium Wave (MW), which is generally used for regional coverage, and Shortwave (SW), which allows for intercontinental transmission due to its ability to bounce signals off the ionosphere.
Key Facts
- Medium Wave is utilized for regional broadcasts, such as Radio Capodistria serving Slovenia, Croatia, and Italy.
- Shortwave enables global reach, with stations like China Radio International and Radio Romania International targeting Europe.
- DRM (Digital Radio Mondiale) is a digital standard used by some stations to improve audio quality on shortwave.
- QSL cards are written confirmations of reception sent by stations to listeners.
- Broadcast schedules often shift between Winter and Summer seasons to account for changes in atmospheric propagation.
Medium Wave Broadcasts
Medium wave transmissions are ideal for localized or regional coverage. For instance, Radio Capodistria operates on 1170 kHz from the Beli Križ transmitter in Portorož, providing 24-hour daily service to Slovenia, Croatian Istria, and Central-Northeastern Italy. This station provides electronic QSL cards (eQSL) to its listeners.

Other regional services, such as Radio Tunis Chaîne Internationale on 963 kHz, have historically served parts of Italy and the Mediterranean Basin, though this specific service is currently listed as inactive.
Shortwave International Services
Shortwave radio is the backbone of international broadcasting. The following schedules are valid from March 29, 2026, to October 24, 2026.
European and Asian Broadcasters
Radio Romania International utilizes the Tiganesti transmitter to reach Europe. They employ both standard analog signals and DRM (Digital Radio Mondiale) on frequencies such as 5955 kHz and 5910 kHz. Similarly, China Radio International broadcasts from Kashi to Europe using a variety of frequencies including 7340, 7435, 7265, 7345, and 17525 kHz, depending on the season and time of day.

Specialized and Relay Broadcasts
Some stations utilize relay transmitters to reach distant audiences. Radiodifusión Argentina al Exterior and the "I Love Italy" (Voice of Italy) program both utilize the WRMI relay in Okeechobee to transmit to Europe on 15770 kHz. Other notable summer broadcasts include the Voice of Turkey from Emirler, Radio Cairo from Abis, and Radio Vaticana from S. Maria Galeria.

Frequently Asked Questions
What is a QSL card?
A QSL card is a written confirmation of a successful radio reception, exchanged between the listener and the broadcasting station.
What is the difference between Medium Wave and Shortwave?
Medium Wave is used for regional broadcasting with shorter range, while Shortwave can travel thousands of miles by reflecting off the Earth's ionosphere, making it suitable for international broadcasts.
What does DRM mean in radio broadcasting?
DRM stands for Digital Radio Mondiale, a digital standard for shortwave and medium wave broadcasting that provides higher audio quality and efficiency than traditional analog signals.
Why do radio schedules change between summer and winter?
Radio wave propagation is affected by the ionosphere, which changes based on the season. Stations adjust their frequencies and times to ensure the best possible signal strength for their target audience.
What is a relay transmitter?
A relay transmitter is a secondary station that receives a broadcast from a primary source and re-transmits it to reach a geographic area that the original signal cannot cover, such as the WRMI relay in Okeechobee used by Argentine and Italian broadcasts.
