Abstract:

A description of the AD-722 direction finder is given in general terms. To avoid deviation and errors in reading, it should be equipped with a crossed-loop antenna and the instructions strictly followed in mounting the antenna on the aircraft. The same is true of the QE deviation corrector. Recommendations are given for setting the direction finder on the aircraft, using a place in the field free of electric interferences, caused by power lines, signal lines, or other electrical equipment. The QE corrector should not show an error exceeding plus or minus 2 degrees. Higher errors indicate an incorrect mounting of the aircraft antenna. After the direction finder is set on the ground it must be checked in flight at altitudes of 100 and 2000 meters.
