RT7 Strategic Voice & Data Encryptor | HF or V/UHF Radio Secure Terminal

RT7 Strategic Voice & Data Encryptor

Voice, Position and Messaging

The RT7 is a 19-inch rack-mount strategic secure terminal that is part of the RT family and works with any HF or V/UHF radio via the audio interface. The RT7 provides fully secure services including link set-up, digital voice, data and position. The RT7 provides interfaces to connect to an intercom system and Ethernet LAN.

Internal Modem

Internal to the RT7 is the world-class RapidM embedded modem module which provides US MIL-STD and NATO STANAG standard waveforms. These waveforms ensure robust and accurate delivery of sensitive information, such as target position coordinates, even in high radio spectrum noise environments or when radio signals are extremely weak.

Local or Remote Operator

A local operator uses a handset connected to the RT7 front panel. The RT7 provides an address book to initiate private line calls or to send locally entered messages or files. A remote operator, situated away from the device, uses the RT7 via the intercom audio interface. The RT7 can then be operated via RT CommandPoint or MessagePoint Software.

Secure Digital Voice

RT provides the next-generation radio speech encryption solution. RT Secure Digital Voice (SDV) uses the new language-independent TWELP** low-rate Vocoder. This is combined with powerful AES-256 encryption and modulated for HF/VHF/UHF use by a RapidM proprietary digital voice waveform.

Position Tracking

Fielded RT7 and RT5 units periodically send out their position information, allowing other RT7, RT5 and CommandPoint users to track blue forces.


RT provides fast accurate messaging services such as:

  • Chat and QuickText
  • File Transfer: Pictures, etc
  • Reports: CASEVAC, SITRAP, etc
  • Email with Attachments
  • SMS to GSM Networks

RT Key Management Software (KMS-256)

Secure key generation and distribution ensures that all over-the-air communications are end-to-end encrypted.

RT System Configuration Software (SCS)

Easy-to-use software allows rapid creation and distribution of address books, network parameters and device configurations.
