    3. Connect the marker antenna and verify proper operation. 2.11.2 Receiver Sensitivity Although the KMA28 meets FAA TSO-C35d sensitivity specifications, the sensitivity of the receiver has been adjusted to meet real world requirements (150 V and 430 V, soft). This will usually eliminate the need for the avionics shop to reduce the sensitivity in the field so as to prevent early detection of the marker beacons.
