Amateur radio evolves: the power of mobile applications
Amateur radio, although it has always been a technical and specialized activity, has been profoundly transformed by modern technology. Traditionally, amateur radio depended on expensive and complex equipment to transmit and receive signals. This required both advanced technical knowledge and a large investment of time and money. However, with the rise of mobile applications, amateur radio has become much more accessible.
Now, anyone with a smartphone can enjoy amateur radio without having to invest in expensive equipment or have in-depth technical knowledge. Apps have simplified processes and opened up new opportunities to connect with people around the world, all from the palm of your hand.
RepeaterBook: the essential application for locating repeaters
One of the main challenges for radio amateurs is finding radio repeaters that allow long-range communication. Repeaters amplify the signal and transmit it over longer distances. RepeaterBook solve this problem by providing an updated map of radio repeaters globally.

SSTV: the magic of sending images over radio waves
The SSTV (Slow Scan Television) it is a fascinating form of amateur radio that allows the transmission of images over radio waves. Using an audio coding system, radio amateurs can send and receive photos and images in real time. Although the quality of the images is not as high as those we obtain by conventional digital means, simply receiving an image through the radio is something unique and exciting.
How does SSTV work?
SSTV converts an image into a sequence of audio tones that are transmitted over the radio. When the receiver receives these tones, it decodes them and recreates the original image. Although this process can be slow, the thrill of sharing an image over radio waves is still an impressive experience.
Advantages of using SSTV:
- Visual creativity: Users can share images, photos and digital art over radio waves.
- International connection: This technology allows radio amateurs to exchange images with people from all over the world.
- Technical learning: The encoding and decoding process is a great way to improve signal transmission knowledge.
- Compatibility: There are applications for Android, iOS and PC, which makes it easy to use on different devices.
The use of SSTV in amateur radio provides a visual dimension that complements voice conversations. In addition, it allows users to interact in a more creative and original way, which makes this modality very popular among fans.
EchoLink: real-time voice communication
EchoLink it is one of the most innovative applications in the world of amateur radio, as it allows voice communication in real time.
