[Milsurplus] ADF today

[Ray Fantini]

All this conversation about aircraft communications has me wondering. Do low frequency ADF systems in aviation still exist today? Are any still FAA certified?  I know that you can tune down to the old NDB band and hear some NDB transmitters banging away but who is maintaining them?

My son in law was responsible for maintaining ground systems at Langley (JBLE) and he once drove me over to where the NDB transmitter site was being one of his jobs was disassembling it and although they were using a relatively modern transmitter when in operation you can see where older open wire feeds and the like had once been. Imagine that may have been one of the oldest and first NDB sites in service being JBLE has been in continuous operation now for over one hundred years.
