Description
Secure Voice Hardware Encryption Solution
Protect mission-critical public safety communications with certified hardware encryption.
The Icom UT125 is an official hardware encryption module designed to safeguard high-security voice and data transmissions across APCO P25 radio networks. This high-integrity Icom UT125 Series Hardware Encryption Board for P25 Radios embeds directly inside compatible transceivers to prevent eavesdropping and unauthorized signal interception. Installing the Icom UT125 ensures full compliance with federal security mandates while maintaining crystal-clear voice clarity during tactical operations.
Engineered for law enforcement agencies, federal task forces, emergency first responders, and municipal public safety teams, the UT125 series provides Over-The-Air Rekeying (OTAR) compliance for seamless remote key management. Available in multiple hardware configurations—including standard AES/DES modes and FIPS 140-2 validated modules—the UT125 series scales across both legacy and modern P25 handheld and mobile radio fleets.

Frequently Asked Questions
What is the primary difference between the UT125 FIPS and the UT125 01?
The UT125 FIPS is validated to FIPS 140-2 standards for government AES security requirements, whereas the UT125 01 provides standard AES and DES encryption algorithms for general P25 operations.
Does the UT125 FIPS-2 require a separate license key to activate AES?
Yes, the UT125 FIPS-2 module requires the Icom ISL-P25AES software license key to unlock full AES encryption functionality on F7010, F7020, F7040, F7510, F7520, and F7540 series radios.
What is OTAR and why is it important for the UT125 series?
OTAR (Over-The-Air Rekeying) allows system administrators to securely rekey or manage encryption keys across an entire radio fleet over the air, eliminating the need to physically program each device manually.
Can I install the UT125 encryption board myself?
While the board installs into an internal option slot, installation and Key Variable Loader (KVL) provisioning by an authorized Icom technician or qualified radio programmer is strongly recommended.
Which encryption board variant should I buy for an F7020 radio?
For the Icom F7020 series (as well as F7010, F7040, F7510, F7520, and F7540), you must select the UT125 FIPS-2 variant along with the ISL-P25AES license key.
Will installing the encryption board affect my radio's IP water resistance rating?
No, as long as the radio chassis is properly opened and resealed according to factory service guidelines using intact internal gasket seals.
