Hi Keith,

Thanks for looking at it.  I do have others with spirit in images in them that I will post.  One thing I noticed, that I am finding fascinating is the band on the spectrogram between 2K and 3K.  From running my DRV files through them, it appears that this is some sort of info band where they embed things for us.  Maybe it's only aimed at the recorder, but clearly I see some notation in that band.  I'll try to post more examples.

Here is another copy of image where I played with the color saturation to bring out the writing.  Can you see it now?
