North Korea has been from the beginning of March continually signal jamming radio broadcasts on the shortwave frequency used by the South Korean non-profit broadcaster Unification Media Group (UMG). Given the present situation, in which North Korean residents might be influenced by outside information condemning the regime and explaining the purpose of the sanctions imposed by the United Nations, the regime has showed the will to block sources of outside information that might cause unrest.
The shortwave frequency […] in question, 7515 [kHz], has been actively jammed starting on March 1st making it extremely difficult for North Korean listeners to tune in. On the 15, UMG organization began using three receivers to test out reception at that and adjacent frequencies on a daily basis and was able to confirm that the exact signal is being jammed.
The blocking effort is being concentrated on the time period from 10pm- midnight. Specifically, from 10-11pm the jamming is very strong. The signal jamming is undetectable from midnight to 1am. The signal blocking became weaker at midnight on March 15, from which point onward the entire three hour broadcast was audible. Starting on the 17, UMG moved the frequency, but the jamming operators seemed not to notice because the interference continued on the old wavelength.
Many thanks to SWLing Post contributor Andrea Borgnino who, as a follow-up to his post yesterday, is sharing the following photos of the Radio Nacional de España (RNE) Casa de la Radio in Pozuelo, Madrid, Spain. Andrea also includes some excellent interior shots of the Radio Exterior de España studios. Click on the images below to enlarge:
Andrea Borgnino–journalist and Internet Content Manager for RAI (RadioTelevisione Italiana)–posted a couple of photos of the Radio Exterior de España studios on Twitter this morning, so I thought I’d share them here on the SWLing Post:
While the audio sounds identical to that of UVB-76’s on 4,625 kHz. I strongly suspect this is simply a pirate radio station relay–especially since it’s broadcasting just below the 40 meter ham radio band. Either way, it’s a great catch! Thanks for sharing, Andrea!
