Maybe it's the location? Dallas is pretty flat, but Knoxville has sirens 
usually on ridge tops, so they can be heard for quite a distance away if you're 
in the right spot.

So, for my experiment, change it to a half mile. Surely nobody is going to play 
the long call more than a quarter mile off stage....

The range of almost all outdoor warning sirens is one mile.  Strong winds
can decrease the range on the up wind side, but do not increase the range on
the downwind side.

This for a study performed for the City of Dallas when it was trying to
determine how best to warn its citizen of impending tornados.  I believe the
study, by a consulting firm that slips my mind, was done in the 1970s.

 Actually, a good experiment would be to wait until they test an emergency
siren. Find where it is and check the pitch with a tuner - if possible. I
guarantee you that if it is a clear/fair day with a constant temperature,
you can drive a few miles away and if you can still hear it, the intonation
would be almost if not the same.

Sometimes, when waiting for Long Call, the spotlights in my back tried
to grill my ass. Nice for the horn, as it gets warm & less moist
accumulates.

And at the edge of the stage opening, with these 10.000 W beamers, no
problem of 
getting
to flat, but rather sharp. As the old saying "If too flat, better too sharp
!"
