Do ADF receivers have a false info warning?

ADF navigation relies on bearing to a non-directional beacon, and the display does not include an automatic false information warning. The bearing indicator shows direction to the station, but signal quality can be affected by noise, interference, multipath, or even a misidentified station, so the equipment doesn’t inherently flag when the information might be wrong. That’s why pilots verify by listening to the NDB’s Morse ID, checking signal strength and quality, and cross-checking with other navigation sources (such as VOR/DME or GPS) or by dead reckoning. If the signal seems unreliable, rely on other data and don’t base decisions solely on ADF information.
