ADB-72-w Technical

The ADB-72-w 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-w 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-w 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-w module offers a programmable “autodetect” option, enabling automatic receive operation while the radio is operated in secure mode.

The ADB-72-w voice security module installs easily into many VHF/UHF mobile and portable radios. It contains upto 16 different programed keys which are selectable by either a momentary or BCD switched input (you may order the module configured in either way, however, you can change this yourself by adding or removing resistor links). All other IO ports can be configured as High/Low or momentary.

The ADB-72-w module can be used in both portable and mobile radio systems 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.
