.•THE TRUTH IS,
February 22
On J-jcrm 'Uth, owi -n.onth oxactlv aft'-or zhc reloaso of the
report on Rallistic Acoustics, by the NATIONAL ACADMfY" OP
SCIENCES Panel (NAS), I obtained a second gcn^-Trition tape (of
high quality) of the original channel 2 Dallas Police gray-audo-graph
disc, used tc record the voice traffic during President
Kenned/'s r.otorcade, on the day no one will ever forget: November
2.^, 1963. "^his tape was made for me by an NAS Panel member,
Richard Gar Win. ,
The purpose for obtaining this important piece of JFK evi­dence
was to study very closely all of the missing information
that is not included on the so-called "critic's copies" of the
channel 2 tape.
For those who haven't heard the tape, there is much missing,
plus, a lot of skipping/repeating, just as an LP record skips due
to a poor stylus. The audo-graph disc recorder used by the Dallas
Police had a worn "worm gear", plus, the stylus was in poor shape.
When they transfered the disc onto tape, the Dallas Police
recorded it the way it was and it skipped and repeated many times.
In I96L1, when ther began making transcripts of the tape onto paper,
accordingly, they had to back up and play over and over again. The
broadcasts weren't 30 easy to understand. This too, accounts for
much of the wear on the disc.
I had been ':old by NAS panel member, Paul Horowitz, that they
had made a non-.R'pping copy of the original channel 2 disc from
12:03-12:14.3, and ohat it contained each and every broadcast originally
corded thai

day.
sixty- •;ven of the NAS report, how the NAS psuiel members
..-lade this tape is briefly explained. It reads in part: '' The gray-audo
graph disc (Channel 2) could not bo played on an original gray playback
unit without introducing skips and repeats.
It was possible to play it successfully without either of these
artifacts being introduced by using a phonograph turntable and phono­graph
arm, cartridge and stj/lus.
However, phonograph turntables operate at a constant RPM, where­as
Gray equipment maintains a constant linear velocity of the record
relative to the stylus.
'loreover, the Gray Audograph records from the inside out, where­as
normal records begin on the outside. Thus, when the tapes are
plaved back, there is a speed distortion that causes material at the
beQ;irming of the tape (the inside of the record) to be slowed down,
and the material at the end of the tape (end of the record) to be
speeded up relative to true speed.
"Speed distortion" is no joke. However, most reel to r-cel
machines contain two speeds: 3 3/h inches per second, and 7 1/2
inches per second, ""y machine has both, so I was able to r -record
the taTJe made for me '^onto cassett', -^^owed down to 3 2>/h I?S.
Since "this copy was recorded ,!;' 7 '^/2 IPS. If I were to play it at
7 '1/2 IPS, it would play totally too fast, and hardly a word would
be unders tandable . ^Ji^nuic^ —
