The DV-520 radio is the latest addition to the Delta fleet of radios bringing the tried and true DMR radio technology of the DS400 series to the mobile market.  The DV520 is the perfect fit for any vehicle environment from Utes to heavy equipment.

The DTMA digital technology allows dual use of the same frequency through a repeater or radio-to-radio, effectively doubling the number of talk channels available (when operating on a private frequency).  The display allows for full digital caller ID as well as easier navigation of the zones, features, and channels during use.
