Caltta PH660 is a DMR Tier 2 portable digital radio operating in the 400-470 MHz VHF band, equipped with a color display and a keypad. Designed to organize a professional radio communication network in locally concentrated, small groups of users who need a reliable way of communication.

Analog and digital modes of operation allow the radio to be used in mixed radio fleets and gradually migrate from analog to digital communications. Caltta PH660 will be a reliable assistant in the case of arranging a communication network for professional users who need radio communication for a long time. Design features and functionality allow the PH660 to be used in indoor and outdoor areas - in warehouses, construction sites, production and sensitive facilities.

ARC4 40bit and AES128 encryption, AES256 is compatible with Motorola, Hytera, Kenwood and more. AES - purchased with a separate license.
