The success of King Radio began with the highly popular KY 90 VHF communications radio, known for its clarity and low cost. Over the years King Radio produced many hits such as the KDF 800 Automatic Direction Finder and the KX 155 Navigation/Communication radio. Many of these products can still be found on aircraft flying today.
In 1970 King Radio released the KX 175 the first low cost all solid state VHF navigation and communications unit with TSO design approval, which was the first affordable general aviation digitally synthesized radio, which together with its derivatives, the KX170B and KX 175B, became what is known as the most reliable radio of its times, for use in general aviation.
The BendixKing brand has remained popular with aviation enthusiasts, and both AlliedSignal and Honeywell have used the brand on their general aviation products to this day.
