It's my understanding that the way the CDBS database is now set up, 
it pretty much has to have separate records for day and night 
operation for each AM station - and if anything at all is different 
between day and night (in this case, 10 kW day vs. 1 kW night), it 
absolutely will have two records.

There are still a lot of "ND1" records in the database, because it's 
not automatically updated to reflect the new standards unless a 
station applies for a change of some sort. Look, for instance, at 
KOZI 1230 in Chelan WA - it was in the database as "ND1," but has 
filed a minor application to correct its coordinates. There's no 
actual change in the station's operation, but when the application is 
processed, KOZI will become "ND2" in the database.
