Hi!
Isn't the mode most NDB's use called A3A (tone modulation with
continuous carrier).
A3J again is "voice AM", continuous carrier modulated by speech or
similar non-digital information such as music.
A2A indicates that the carrier is keyed together with the tone
modulation so there is no continuous carrier for easy direction finding.
Correct me if I'm wrong, I'm curious since have tried to figure out
how the mode designations really work.

Quoting Clemens Paul <[email protected]>:
A2A (or tone modulated AM)
Just what most NDBs are using.
