Digital Radio Mondiale in the 26 MHz band
(25.670 - 26.100 kHz)
DRM works on HF, particularly in the 11M shortwave band. DRM on 26MHz can be a great alternative to other local broadcasting options. Now with the Newstar DR111, this band might even be more feasible and attractive
Countries around the world are migrating from analogue to digital broadcasting techniques for television and radio. This document looks at sound broadcasting opportunities in the 26 MHz band for local coverage using Quasi Line-of-Sight propagation.
The document is intended to:
- describe service planning in the 26 MHz band and explain why, and how, a broadcaster might use this band for local broadcasting using the Digital Radio Mondiale (DRM) system;
- address some potential interference concerns when using this band for local transmissions during high levels of solar activity;
- provide new information based on practical experience with DRM used for local coverage in the 26 MHz band.
This document examines the possibility of using digital formats in the 26 MHz HF broadcasting band 25 670 kHz to 26 100 kHz. This part of the spectrum has limited use at the moment.
