North Korean Diplomatic FSKFrequency-Shift Keying link, teletype radio diplomatic usage. Also known as DPRK-FSKFrequency-Shift Keying, KRE-FSKFrequency-Shift Keying, DPRK-ARQAutomatic Repeat reQuestAutomatic Repeat Query, and KEGURI. Has a FECForward Error Correction stream mode and a burst ARQAutomatic Repeat reQuestAutomatic Repeat Query mode.

The ARQAutomatic Repeat reQuestAutomatic Repeat Query FSKFrequency-Shift Keying mode has two speeds, 600 BdBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second. and 1200 BdBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second., and both have a 600 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). shift. The 600 BdBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second. FSKFrequency-Shift Keying mode has a packet length of 217 msmilliseconds (.001 of a second) (323 msmilliseconds (.001 of a second) of pause), with 130 bits per packet. The 1200 BdBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second. mode has a packet length of 210 msmilliseconds (.001 of a second) (290 msmilliseconds (.001 of a second) pause) with 264 bits per packet.

The FECForward Error Correction FSKFrequency-Shift Keying continuous stream mode uses 600 BdBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second. and 600 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). shift. A reversal variant has also been seen.
