Short Description CISCommonwealth of Independent States (CIS), the former Soviet Republic-1280 is a OQPSK (Offset Quadrature Phase Shift-Keying) modulation data modem signal. Also known as Soviet Mil(MOD)/FAPSIFederal Agency of Government Communications and Information (Russian Agency)/PTTPush To TalkPress to TransmitMinistries of Postal, Telephone, and Telegraph Service (Soviet Agency) system. These stations are recognizable in that they are all placed on .081 offsets from a kilohertz or half kilohertz point.

CISCommonwealth of Independent States (CIS), the former Soviet Republic-1280 is a OQPSK (Offset Quadrature Phase Shift-Keying) modulation data modem signal. Also known as Soviet Mil(MOD)/FAPSIFederal Agency of Government Communications and Information (Russian Agency)/PTTPush To TalkPress to TransmitMinistries of Postal, Telephone, and Telegraph Service (Soviet Agency) system. These stations are recognizable in that they are all placed on .081 offsets from a kilohertz or half kilohertz point.

OQPSK means the width of the signal is exactly equal to the speed of the signal, which in this case is 1280 bpsBits per second (bps).

Data on this signal is found in Roland Proesch's Technical Handbook for Radio Monitoring HFHigh Frequency (3-30 MHz).
