Earl,

What's the BP on the 489? I noticed that when you had the 120's whistle on SLRG 18 that it didn't sound quite the same as on the Kistler recording. I think the 120 had a BP of 220 psi, while the 18 had 200 psi. I've blown my Powell on 150 psi and it sounds different as well. I think the higher pressure results in a slightly higher overall frequency and it may bring the whistle more in tune.

I also wondered if the higher altitude and dryer air made a difference, as opposed to the recordings of 120 in the rain at sea level.
