It's hard to tell whether this is an Allertor or a 500AT. I'm leaning more towards an Allertor.

I would say it's an Allertor. If not a SD-10

It's definitely not an SD-10, because it's rotating. It's sounding at the same pitch as that 500AT that Archon recorded recently, but I've also heard an Allertor that sounded at that pitch.

Then I would say an Allertor.

Thats definitely an allertor. The wind down gives it away

Could it possibly be a P-10? They're 9/12 port as well. The only noticeable difference between that and an Allertor as far as I can tell is that the Allertor seems to be amplified a little more so than the P-10. Without the fiberglass housings, they're both the same thing.

It is a 15HP Allertor
