Digital Radio Mondiale (DRM) Software Tools
Find applications for transmitting and receiving Digital Radio Mondiale signals, including SDR integrations and signal processing tools.
Digital Radio Mondiale (DRM) and other digital modes allow hams to transmit and receive high-quality audio and data over HF bands, often with less power and better signal-to-noise ratios than traditional analog modes. These digital techniques are especially useful for long-distance DX contacts where propagation can be challenging, providing clear reception even under difficult conditions. Operators experimenting with DRM can achieve near-FM quality audio on shortwave frequencies, opening up new possibilities for amateur radio activity.
This category provides software tools for both transmitting and receiving various digital modes. Hams can find applications like Dream, an open-source DRM receiver, for decoding digital shortwave broadcasts. For those interested in digital image transmission, software such as EasyPal and DIGTRX offers robust solutions for Slow-Scan Television (SSTV) over the air. Additionally, tools like Spark enable real-time modulation for DRM and DRM+ signals, allowing operators to experiment with transmitting these advanced digital formats.

EasyPal is a sophisticated digital Slow-Scan Television (SSTV) application that utilizes soundcard technology to encode and decode SSTV signals. Developed by the late Erik Sundstrup (VK4AES SK), this software has evolved into a versatile communication tool for amateur radio operators, extending beyond basic image transmission capabilities. EasyPal implements Digital Radio Mondiale (DRM) encoding technology, enabling efficient data transmission over narrow 2.5 KHz channels on both HF and VHF frequencies with remarkable speed. The application supports multiple file formats, including jpg, pdf, txt, doc, and xls, as well as specialized forms such as ICS-213 and ICS-213 (ARES). Additionally, EasyPal offers email functionality through designated repeater stations with internet access. Its responsive development history and robust feature set have established it as a premier digital SSTV solution in the amateur radio community, though users of Windows 11 should note specific configuration requirements to ensure optimal performance. -
Spark is a realtime modulator software for Digital Radio Mondiale DRM, DRM+ and analog FM/AM radio standards. The software supports all code rates, bandwidths and robustness modes (A, B, C, D, E) published in the DRM standard as well as all mapping schemes, such as Standard Mapping
