Sounds pretty technical to me. I got my IFR rating in 1980, back before GPS moving maps, and ADF/NDB stuff was still widespread. Still, I never really needed to know what the BFO position on the ADF did, nor did I understand it. In short, I wouldn't worry about it.

thank you sir
I can't, but since the note in that technical attachment speaks to NDBs with A2A idents I'd assume this BFO stuff has been long since phased out. Maybe you can find one in Somalia or some other third world country? I've only had to ID and fly a half a dozen or so NDBs in the US and a couple in Canada. I only ever identified them the normal way, just like a VOR. Presumably these have A2A idents then?

As I recall the BFO switch is only used to IDENT certain NDBs. That said, there are not any in the US that I know of, in fact IIRC the instrument manual I studied way back when said that they were only in other countries. Britain specifically comes to mind for some reason, but that could just be because I think the british are generally backward enough to require a special unique setting for identification
