F2721D

For organizations who run an analog radio system and must migrate to a conventional P25 digital system, Icom provides one of the best solutions. The new F1721D series mobile allows you to program P25 digital and/or FM analog mode per channel. Flash ROM capability means future upgrades and flexible customization, tailored for your system. Moreover, built-in multiple tone signaling capability and an optional voice scrambler satisfy existing analog FM system requirements. This new Icoms range frequency coverage and rugged construction ensures a flexible, long life radio for you. Icom is the smart choice for current and future public safety communication needs.

AES/DES digital encryption activation software

AES and DES are encryption standards required by public safety agencies. The IC-F1721D, F1821D series provide secure encryption with DES and AES accordingly when activatied with EX-2785 J02 (for DES) and EX-2785 J03 (for AES) activation software.

Interoperability

The IC-F1721D, F1821D series is APCO Project 25 (P25) compliant. It ensures interoperability with other manufacturers P25 digital radios in conventional mode. Program digital and/or analog FM modes per channel. The mixed mode scan allows you to detect and receive both analog FM and P25 digital modes and to transmit either mode depending on programming.
