Why did the North Korean regime turn on a new shortwave transmitter with the digital DRM standard (Digital Radio Mondiale)? And, above all, who listens to the transmissions, given that the receivers cost at least a hundred dollars, an enormity for a population starved by the supreme leader. RedTech, a French technology magazine, examines various hypotheses and concludes that there is nothing strategic about it. It will probably distribute the signal of KBCS (Korean Central Broadcasting Station) to repeaters (a system already used in the past in analogue) without setting up an expensive network of terrestrial transfer links. The transmitter operates on 6140 kHz with an estimated power of 50 to 100 kW and is in addition to the one on 3205 kHz that has been on air for more than a year. It uses AAC+ compression because the engineers used software that does not support the latest standards. More details in the RedTech article.

The PBC (Pakistan Broadcasting Corporation) has asked the government to make it compulsory for cars to be equipped with digital receivers in the next five-year plan for the automobile industry. For some time now, public radio and television have been broadcasting using the DRM digital standard in the AM and FM bands. DRM (Digital Radio Mondiale), unlike DAB (which uses VHF channels in band III), is a digital broadcasting system applicable to all frequencies, from the HF bands (LW, MW, SW) to VHF (bands I, II, the FM band, and band III). And it foresees investments to complete the digital migration in the next five to seven years, to improve audio quality (claimed to be equal to that of a CD) and energy efficiency.
