ETM 1820M

The Modem 1820M supports multiple waveforms;
complementary further waveforms may be loaded onto the HF Modem if required.

The ETM 1820M-x facilitates the following transmission modes:

    • MIL-STD-188-110A/B
    • MIL-STD-188-110B Appendix F (ISB)
    • STANAG 4539 Annex B, inclusive Autobaud
    • STANAG 4415 75 bit/s (NATO robust waveform)
    • STANAG 4481 FSK
    • STANAG 4285, including Annex E
    • STANAG 4529 (Narrow-Band)
