Thanks, Lyle. That makes sense to me.

So, maybe that WAS my signal and Larry gets QSL #1.

The problem with Larry's capture is that it shows a keyed signal prior to 10
pm and no signal a minute or so before the capture at 10 pm. PI was key down
until after 10 pm so there should not be the two sets of 3 signals followed
by nothing.
