I noticed it, too.
I was up at the top-end all by my lonesome because I didn't want to step on anybody!

I took this screen grab of this morning's eastern FO-29 pass, and what it
shows is in my opinion very illustrative of a problem that is getting worse
even on days other than Field Day.
Spread out! There is no good reason that we should have a dozen operators
fighting over the center 15 kHz of a 100 kHz wide transponder. Remember the
gentlemen's agreement is the lower third is for CW, middle 1/3 is for mixed
ops, and the upper 1/3 is for SSB. There is nothing magic about the Doppler
shift at the very center of the passband that simple addition and
subtraction can't duplicate elsewhere.
Just my opinion, and please take it constructively.
