Our Story

A tale of two engineers and a city in Colorado.

  • Washington Monument - Washington, DC


    Our Humble Beginnings

    Brothers Eric & Ethan Funk complete their undergraduate education and pursue RF engineering careers. Eric completes his Ph.D. at the University of Maryland, eventually becoming a Research Engineer at the Naval Research Lab in Washington, DC. Ethan hones his RF Design skills in industry, working in Rochester (NY), as well as in the Maryland/DC Metro area and Boston.

  • Mountains and Lake

    July 2003

    An RF Engineering Firm is Born

    Drawn by the majestic mountains of Colorado, a love of outdoor adventures, and an entrepreneurial spirit, Ethan and Eric combine their skills and expertise to form Red Mountain Radio LLC in Ouray, CO. Ouray, known as a basecamp for outdoor adventure, now became our basecamp for RF Design as we equipped a complete RF development lab. The firm's namesake, Red Mountain, was home to a world-famous silver mining boom in the 1880s.

    Full Service RF Design

    The firm began with specialized RF design for aeronautical communications and radar. As the consumer electronics industry grew, we increasingly delivered full-product designs, integrating RF, power, and digital circuitry with embedded microprocessors and software. Increasingly, we've become a one-stop destination for electronics design.
