The AIRTERM (KY-100) is a lightweight terminal for secure voice and data communications. The KY-100 provides wideband/ narrowband half duplex communication that functions in conjunction with:

  • TACTERM (CV-3591/KYV-5)
  • VINSON (KY-57 & KY-58)
  • MINTERM (KY-99A)

The low profile Z-AVH RCU can be used when there is insufficient space to mount a KY-100 within easy reach of an operator or when there are multiple operators.

The KY-100 is based upon the KY-99A architecture and provides flexible interface capability. Operating in tactical ground, marine and airborne applications, the KY-100 enables secure communication with a broad range of radio and satellite equipment.

The KY-100 is backward compatible with the VINSON KY-58 and has the same connector and pin-outs for the wideband operational modes.

The KY-100 provides voice at 2.4 kbps using the DoD standard LPC-10e for narrowband voice modes. The KY-100 also provides CVSD voice at 16 kbps and 12 kbps in the wideband voice mode.
