From RF Engineers and inspired by the former Dayton Industrial receivers that we all came to love, the Watch Dog is a truly versatile FM / AM / NOAA Weather receiver, real-time RDS decoder, and configurable alarm system.

The Watch Dog is a truly versatile FM / AM / NOAA Weather receiver, real-time RDS decoder, and configurable alarm system. Designed with Broadcast Radio and 24x7x365 operation in mind, the Watch Dog receiver contains a 32-bit microprocessor and Software-Defined Radio (SDR) receiver core running on top of an industrial standard Real-Time Operating System (RTOS).

Featuring Class AB balanced audio / StudioHub+ and Class AB single-ended audio output, the Watchdog’s modular and swappable audio section means future expansion capabilities, including the planned AES3 audio output module. The fully configurable monitoring and alarm system notifies you of signal problems immediately, either via front panel LEDs and/or rear panel open-collector outputs. Programmable API / easy automation means that the Watch Dog can be used to fulfill a variety of needs and can be used in a variety of roles.
