Long-distance radio reception in the new standard

Long-distance radio reception in the new standard

Based on the results obtained, specialists drew conclusions and published them in the press. According to the published information, this standard provides maximum coverage and significantly improves the quality of audio content. Based on this, it can be argued that such a broadcasting technology will become mainstream in the near future.

Today, there are a huge number of adherents of DXing who are engaged in decoding signals from remote sources. Most likely, they will be pleased by the news that DRM is planned to be used for various bands. This will allow for quality close to CD. Communication will mainly take place on the following frequencies.

• 25.6–30 megahertz

In this case, wave propagation will occur not only in a straight line, but also by reflection from the Earth's atmospheric layers. With proper system configuration and optimal antenna installation, the transmission range increases by several hundred kilometers. Moreover, ideal communication for DXing is possible even in the presence of active urban interference and high-rise buildings.

• 30–50 MHz

It is one of the most popular service bands, used by numerous stations, enterprises and organizations. It has physical properties that occupy an intermediate position between VHF and HF. It allows transmitting information beyond line of sight. Nevertheless, it is recommended for use in flat terrain with few high-rise structures. For reception, equipment from Western manufacturers is most suitable, allowing to catch signals with a tolerance

• 51-174 MHz

The band has the highest degree of protection against interference, so it is convenient for official purposes. In most foreign countries, these frequencies are used in the creation of paging and cellular communication systems.

According to Department employees, the DRM digital standard operating on these frequencies will significantly improve signal quality and reduce costs for antennas for outdated equipment of users of these radio frequencies.
