I almost never let the pile-up call again without making a transmission. One
wants the pile-up to develop a rhythm... to know that you will make SOME kind
of transmission after the first 3 seconds. That gets most of the pile in the
habit of stopping transmission to listen, which means more stations will be
listening when you make your transmission.
So now, what to send?
If I only have a partial call, normally I just send the partial call with a ?.
The risk in continuing to send the exchange is that the full call never gets
completed. "1AW?" or, often, the question mark in the uncertain locations
"W1?W"
However, if the pile is very small and the signal of the caller station was
good (i.e., I just fumbled the reception, or he got briefly stepped on), I
would go ahead to send the exchange with the partial call... and repeat the
call fragment with ? at the end of the transmission to emphasize that I only
have a fragment. Remember, the other station may have as much trouble hearing
you as you have hearing him, or even more! It's critical to convey to that
station that you do not have his full call! Otherwise he may just rattle off
his exchange and go away -- and you'll have to remove the potential Q. A
second reason for making the call transmission at the end is that more of the
pile has (hopefully) stopped transmitting as they notice you're already
answering someone... and they can get the idea to whom you're responding. So,
only with small pileup and good signals, I send: "?1AW 599 5 ?1AW"

If I copied both stations, I log both.
If I only copied one, I repeat the call of the station to whom I am responding:
W1AW TU K3NA
If I copied more than one call in the initial pileup, and picked W1AW to answer
first, I will use the "next" approach:
TU NW W4BVV 5NN 5
But I never grab a second call from the unruly operators who keep calling while
I am working someone; that just encourages unruly behavior. Even if I know
exactly the call of an unruly operator, I will only answer him after he has
made his transmission at the proper time.
