 Description   Features   Specs   Accessories 


Each D-Series radio can be tailored precisely for the user's specific needs. For example: each D-Series radio can be programmed to display as few as 1 channel or as many as 10. Features like channel scan, weather scan and weather alert can be turned on or off depending on the need. The SST D-Series radios are powerful and feature rich, yet flexible and cost-effective.

Lightweight, small and easy to carry, yet capable of withstanding a 6 foot drop onto concrete. In fact, ounce for ounce, the Patriot D-Series radios are tougher than any other professional business radio in its class.

Ritron's PATRIOT products are put to task daily in tough worksite environments. Built to rigorous standards for design, manufacturing, and engineering, these products are your solution for effective wireless radio communications. The PATRIOT radio line stands out from the competition.
