ADB-72-RPU Digital Encryption Modules (Wire-in option board for RELM RPU3300U Portable and Mobile radios – or other projects)
ADB-72-RPU Crypto Level I Digital Modules – 20 bit Key
The ADB-72-RPU is designed for simple wire-in installation into the RELM RPU3300 series VHF/UHF portable radios.
The ADB-72-RPU series digital encryption module is designed to provide medium level (Class I) protection of two-way radio communication from eavesdropping by unwanted listeners in order to keep confidential information private and safe. The ADB-72-RPU module utilizes AES digital encryption with the strength of over one million key combinations to protect from attacks on confidential conversations. As an investment in safety and privacy, it provides an affordable balance of cost and security for mid-level voice encryption for use by commercial users, police departments, public safety organizations and other organizations as a defense against unauthorized interception of private and sensitive voice transmissions by casual or clever and determined listeners.
When the radio is used in secure mode, if an eavesdropper attempts to listen to a conversation, they will not hear any vocalization. There will be an absence of speech referred to as “white noise”. As the ADB-72-RPU uses a digital communication channel in an analog radio communication system, it also rejects background noise, helping the receiver to clearly hear and understand the communication. The ADB-72-RPU module offers a programmable “autodetect” option, enabling automatic receive operation while the radio is operated in secure mode.
The ADB-72-RPU voice security module installs easily into many VHF/UHF mobile and portable radios.
The ADB-72-RPU module can be used in Relm RPU3300 series radios that utilize conventional analog repeaters operating in the 12.5/25 kHz radio spectrum. It can be used a variety of radio networks including Simulcast, LTR, and voting systems. Plus, it is compatible with dispatch systems featuring Check, PTT-ID, OTAR, and GPS location information. Other options include compatibility with frequency inverters using analog keys as well as compatibility with double-inversion voice band scramblers using analog keys.
