The DPRK – FSK 600. The modem is based on BFSK bursts transmitted in the lower sideband mode. There are two possible waveforms: 600Bd / 600Hz as default (case of video), and 1200Bd / 600Hz as an option. The 600 Bd FSK mode has a packet length of 217 ms (323 ms pause), with 130 bits per packet. The 1200 Bd mode has a packet length of 210 ms (pause of 290 ms) with 264 bits per packet. Signal picked up by the URE Listening Service, IARUMS URE (IARU Monitoring System, URE). More information about IARUMS URE at https://www.ure.es/iarums/
