Short Description STANAG 4539 or MIL-STD-188-110B/C Appendix C is a HDR (110B) / MDR (110C) serial PSK/QAM signal that can reach speeds up to 9600 bps (12800 bps with no interleaving).

STANAGNATO Standardization Agreement (STANAG), defines processes, procedures, terms, and conditions for common military or technical procedures or equipment between the member countries of the North Atlantic Treaty Organization (NATO). 4539 or MIL-STD-188-110B/C Appendix C is a HDR (110B) / MDR (110C) serial PSKPhase-Shift Keying/QAMQuadrature Amplitude Modulation signal that can reach speeds up to 9600 bpsBits per second (bps) (12800 bpsBits per second (bps) with no interleaving). In 110B, this was designated as High Data Rate, but in 110C, this mode was recategorized Medium Data Rate. It is officially designated as "HFHigh Frequency (3-30 MHz) data waveforms for data rates above 2400 bpsBits per second (bps) in 3 kHzKiloHertz (kHz) 10^3 Hz channels."

Has similar operation and parameters as the mandatory MIL-STD-188-110 Serial mode, but uses different modulations and higher speeds. In addition, each speed except for 12800 bpsBits per second (bps) has 6 different interleaving modes. Ultra Short, Very Short, Short, Medium, Long, and Very Long.
