An attached refclock yes.  And using one of the drivers from here:

What I know about broadcast I learned from the docs, as I've never used it 
myself.  But from what I understand a broadcast server will continuously 
send out time information, and a broadcastclient will receive these if 
configured, and automatically us it as a synchronization source without 
having to manually specify it in the ntp.conf file.  Perhaps someone else 
could elaborate on this.

It has nothing to do with queries, as in ntpq or ntpdc queries, if that's 
what you were referring to.
