Digitally tuned solid state automatic direction finder which provides bearing information to stations in the frequency range of 200 KHz to 1799 KHz and which also provides audio reception to enable pilot to identify stations
Used with KA-44B combined loop/sense low profile ADF antenna OR KA-44 blade antenna
Can be used with single needle KI-227 ADF indicator or dual needle KI-228 indicator (both indiactors available with manual or slaved compass cards)

Internal timer for flight time and elapsed time which proves valuable for non-precision timed approaches, fuel management, dead reckoning navigation
Automatic dimming circuit adjusts the brightness of the display to compensate for changes in the ambient light level
Coherent detection design rejects unwanted frequency interference, achieves significantly greater range and has less suspectiblility to engine noise, static and atmospheric interference
Flip-flop frequency display allows to switch between pre-selected "standby" and "active" frequencies
Operates on any voltage from 11-33 VDC with 12 watts power consumption
