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 F2821D 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. Icom’s frequency range 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.

P25 Solution

The F2821D is P25 compliant. The mixed mode scan is compatible with both analog FM mode and P25 digital mode allowing users to 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.

Encryption Options

For basic encryption the F2821D comes with a built-in inversion type voice scrambler. For a slightly more secure system, the optional rolling and non rolling (UT-109/UT-110) are available. Many public safety agencies require high level encryption: AES & DES. Icom offers an AES and DES upgrade to provide secure encryption for the F2821D.

Rugged Construction for Public Safety Users

With heavy-duty construction, the F2821D is built to last. The F2821D incorporates a 4W speaker in an impact resistant polycarbonate front panel for crisp clear audio, and includes a backlit 10-keypad for extended operation.

Programming - Radios are programmable and will require programming to work with an existing system. Software and programming cables are not included with the radio and must be purchased separately.

Do I need an FCC License - FCC licenses are required for many business radio frequencies. The biggest advantage to licensing your frequencies is exclusivity. Using common or default frequencies often means dealing with interference from others nearby who are using the same frequencies.  We can help with the FCC application process.
