Using digital voice
Overview of digital voice options
Digital voice is now offered through two distinct methods. The
latest method offers digital voice with or without MIL/STANAG
2G Data, and with or without an AES-256 Encryption upgrade;
these are referred to as the DV options with/without an AES-256
Encryption upgrade. The earlier method offers AES-encrypted
digital voice only, and is referred to as the AES-256 DV Encryptor.
Stations must have the same digital voice method activated for
successful communication.
NOTE: DV options with/without an AES-256 Encryption
upgrade are implemented by the RM50 encryptor
module. You must have the RM50 module fitted to
use these features.
NOTE: The RM50 module can be upgraded from TPS
System Programmer or from a USB stick. See
Upgrading the transceiver via a USB stick on
page 122 for more information.
CAUTION: A permit from the Australian government is required
if you want to upgrade the RM50 module with an
export controlled version firmware package, which
enables AES-256 Encryption and Low Rate DV
capabilities.
