Well, I am about to burst your bubble, Mike, because Herbert is not
correct about the "brieftone".
There is a "brieftone" that is very audible at the conclusion of Decker's
2nd transmission, that Herbert claims is not there. It is very brief, but
it appears on both channels one and two.
What you will hear in this small clip is first, the "brieftone" as it is
heard on channel one, followed by how it sounds on channel two. I repeated
the segments several times.

Since there is no speech by Decker accompanying the "brieftone", you
should have absolutely NO problem comparing the two sounds.
I'm not going to hold my breath on this. You two both have your minds
made up. I am posting here for the regulars and the lurkers to hear for
themselves that the two tones I supplied are one and the same, from the
two different radio channels in use 11-22-63.
