That station doesn't have a DA. Might it be possible that KIQN once
had a DA-N and then gave it up?


I think it was a low-power daytimer that upgraded to the best it can get.


Does nighttime coverage really matter any more? How much radio
listening is there at night (after PM drive)? And, more to
the point, is that an audience worth selling to?


In LA, 53.3% of all persons 12+ listen to radio in the 7 to Midnight time
period.

Keep in mind that in deep winter, sunset may happen in the middle of
afternoon drive and sunrise late in morning drive. That means a daytimer in
a middle latitude may operate from 6:30 AM to 4:45 PM. So night operation is
critical.


I wonder if a good, solid cost/benefit analysis has really been
done for stations with limited coverage that are still staying on 24/7.
I suppose the costs these days are marginally low enough that a
small amount of revenue would make it worthwhile.


Since overall ratings performance and pricing are based on 6AM-Mid, Mon-Sun,
you don't see many daytimes doing well anywhere.

Are there that many daytimers left? The only one I know if in LA (or
anywhere
else for that matter) is KBRT-740 on Avalon (KCBS stomps on it as soon as it
gets just a little bit twilighty...)

All of the other local daytime-only stations (KIEV-870, whoever's on 900
and 1220 over in Pomona....were there any others) are full timers now
(much to the consternation of the DXers out there....)

P.S. Wasn't the expanded band designed to give these daytimers a place to
go be fulltimers without cluttering up the rest of the band? Well, guess
what
didn't happen...
