Blow whistle to end quarter?

[frezer11]

Just joined, my first post. Looking forward to the discussions!

Here's my question: There seems to be an ongoing discussion within my association about whether or not the calling official should sound the whistle when the quarter ends. I was always taught yes, blow it dead and waive it off immediately if it doesn't leave the hand in time (obviously), blow and give the open palm, clock stop signal if it is released in time but misses, and blow and count the basket if the buzzer goes while in the air. I haven't sen anywhere in the rule books or official's manuals where it says you don't have to, but then again, I also haven't seen anything that specifically says to do it.

So what do you all do? I get the argument that the horn is already signaling the end of the quarter, but what do coaches always tell their players? "Play till the whistle!" Let me know what you think!
