Bfo 737 Ng Adf
Just converted onto the 737 NG and can see no way of selecting a BFO ident...is this done automatically?
On the subject of NDBs can someone tell me what an * next to the freq means on a jeps plate (BFO...NDB)?
I know I should know this stuff but newbie...bear with me.

Depends on the ADF Panel installed i guess, we have several different ones in our NGs but all allow to select Tone to on, which is the BFO tone to identify a station. However we are not required to do so as the station is automaticly identified and that can be displayed on the ND.

On the NG, as with other 737s, it has to be 'manually tuned' and can be 'listened to' but the a/c normally idents and displays the ident (by black magic). The problem is if it does not show an ident (not uncommon) then there can be problems with a BFO beacon in 'hearing' the ident.

No Autotune on the NG except for the "hidden" DME for the radio position fix for the FMC. So yes, as BOAC says you allways have to manually tune the ADF. And of course you can listen to it, your choice if with a BFO tune or without. In europe BFO is rarely needed so the relevant switch usually is on off (says tone right next to the switch, close to the frequency selector of the ADF).
