APPENDIX C
TIMING OF CHANNEL I AND II EVENTS
60
This Appendix discusses the results of a study of the times of occurrence
of certain key events on Channels I and II. The times were determined in two
ways: 1) by listening to the Bowles tapes and by measuring the strip charts (in
Figures C-1 and C-2) of the tape recording signal levels as a function of time;
and 2) by listening to tape recordings made from the original Gray Audograph and
Dictaphone records.
C-1. Analysis of Bowles Tapes
The Channel II transmission "You want me...Stemmons" that occurs about 200
seconds after the transmission by Chief Curry, "Go to the hospital," is clearly
audible and intelligible on Channel I. It provides a common reference point for
synchronizing the Channel I and II tapes, and we can use it to determine whether
the events on Channel I identified by BRSW/WA as shots occurred before or after
Chief Curry broadcast his instructions "Go to the hospital." If these events
occurred after Chief Curry's instructions, they could not be the assassination shots.
The transmission "hold everything..." on Channel I coincides in time with
the last of the events BRSW/WA identified as shots. The strip chart timings
provide evidence to support an explanation of how this transmission could have
occurred at the same point in real time as the matching "hold everything..."
transmission on Channel II. They depend only on whether or not the instructions
"Go to the hospital" preceded the events identified by BRSW/WA as shots.
Channel I Recording
Measurement of the interval on Channel I between "You want me...Stem~ons" and
the conjectured shots is straightforward. The logging recorder (Dictaphone) ran
continuously over the time of interest (even though it was sound-actuated), and
the tape recording that we used for our measurements shows no evidence of skips,
repeats, gaps, halts or similar artifacts that would affect the timing. Table C-1
gives the times of the transmissions of interest to us on Channel I.
A transcript of the relevant portions of both tapes appears at the end of this
appendix (Tables C-2 and C-3). It was obtained from J. C. Bowles. The time used
by Bowles is retained on the transcript even though it differs from the one
favored by the Committee.

Channel II Recording
Measurement of the time intervals on Channel I between "Do you want
me...Stemmons" and "Go to the hospital" is more difficult. The logging
recorder (Gray Audograph) was sound-actuated and did not operate
continuously. So the actual record is shorter than real time. There are
repeats in the Bowles' tape recording that occurred when the Gray Audograph
playback stylus jumped back to a previous groove in the record much as the
stylus on a scratched phonograph record often does. The tape recordings
made available to us initially were in two segments, with a break occurring
between the two transmissions of interest. The first segment was recorded
at a speed different from that of the second segment. All of these
artifacts required compensation in order to obtain an accurate
determination of the interval between the two transmissions. Compensation
was done as follows:
a. Gap
Barger had access to an unbroken recording of the entire interval of
interest from which he was able to show that a section of the original
Channel II recording 0.4 seconds long had not been captured on the
recordings we initially used.
b. Speed Compensation
The relative speed of the two segments of tape can be estimated from
the sound spectrographs discussed in Appendix B. From this analysis we
determined that times measured from the first segment of Channel II, which
we designate Channel IIA, had to be multiplied by a factor of 1.06 to
convert them to the time units of Channel JIB, the second tape recorder
segment. Further, Barger and Weiss ascertained by an analysis of tones on
Channel I and Channel IIB that these two tape recordings were made at
essentially the same speed and that no correction was necessary to convert
Channel IIB times to equivalent Channel I times.
BRSW reported that the Channel I times had to be multiplied by a
factor of l.O5 to convert them to "real" time. We have not made this
additional correction but instead have expressed all of our results in
equivalent Channel I tape recorder time units. Table C-1 shows the

transmissions occurred, corrected for the speed difference between Channel
IIA and Channel JIB.
c. Repeats
Five repeats are evident from listening to the tape. All of these
occurred in places where there were distinctive audible transmissions. As
explained below, not all of these repeats actually increased the duration
of the tape. In two cases the stylus apparently jumped backward to the
previous track and started to repeat, but then jumped forward to the
correct track before the recorder completed a single revolution. When this
occurred, the duration of the tape would not have been lengthened relative
to the duration of the original record. The strip charts of Figures C-1
and C-2 provide the detailed information from which we can determine
whether the duration of each repeat was an integer multiple of the period
of rotation of the record or not, and we used them to identify these two
cases.
The three repeats that can be unambiguously identified by listening
and by examining the strip chart pattern are:
Repeat 1 at 65 sec.
Repeat 3 at 122 sec.
Repeat 6 at 177 sec.
6.2 sec. added, 6.6 sec. corrected time
3.8 sec. added, 4.0 sec. corrected time
3.5 sec. added, 3.5 sec. corrected time
The repeats are multiples of about 3.5 seconds (corrected time), which time
can be taken as the period of rotation of the recorder (the angular
velocity of the recording disk on the Gray Audograph is not constant).
The strip charts also can be used to measure accurately the duration
of the silences. We found one very long (7 second) silence, starting at
155 seconds that we believe was caused by a repeat during a portion of the
tape in which there were no distinctive audible patterns. Therefore, we
have:
OCR for page 64
64
Repeat 5 at 158 sec . 3.3 sec. added, 3.5 see . corrected time
All of these repeats caused the Channel II times to be increased and
the tape timings must be reduced to correct for them. This is done in
Table C-1 in the columns labelled "Cumulative Time . "
There are two other possible repeats, one at 96 seconds (repeat 2) and
the other at 129 seconds (repeat 4). The first of these is not a repeat
that caused the tape to be lengthened, since only a single word (notified)
of a longer passage is repeated . The second ~ repeat 4, is less clear:
Repeat 4 at 129 sees
2.3 sees added, 2.4 sees corrected time
Note that this is not a multiple of 3.5 seconds . In the case of this
repeat and repeat 2, the stylus apparently jumped back for a fraction of a
revolution and then skipped forward to the correct track, thereby
terminating the repeat. The fact that neither of these lasted a complete
rotation means that there was not a spurious increase in the tape duration,
and the timings should not be corrected.
d . Silences
We are told by James Bowles that the recorders had hold relays which
kept them on for approximately 4 seconds after a transmission ended (the
time between the end of a transmission and the recorder turnoff depends on
sound intensity and is longer for very loud sounds). We do not know the
threshold for this hold relay, but it is reasonable to assume that it was
about 10 db below the peak signal voltage.
If a silence is less than 4 seconds, the recorder would not stop and
the recorder time would correspond approximately to real time. If a
silence is longer than 4 seconds, the recorder would stop and chere is no
simple way of determining the duration of the pause that might have
occurred before it restarted.
Note that starting with "Go to the hospital" at zero seconds to
silence A at 106 seconds, all silences are less than 4 seconds. The
OCR for page 65
65
Channel II recorder must have run continuously during this interval.
Starting at 106 seconds, we have a number of silences greater than 4.5
seconds during which the recorder could have paused. They are:
Silence A at 106 sec.,
Silence B at 132 sec.,
Silence C at 145 sec.,
Silence D at 162 sec.,
Silence E at 189 sec.,
4.9 sec. duration, 5.2 sec. corrected time
4.5 sec. duration, 4. ~ sec. corrected time
5.0 sec. duration, 5.3 sec. corrected time
5.5 sec. duration, 5.6 sec. corrected time
5.5 sec. duration, 5.5 sec. corrected time
This pattern of pauses means that, although the tape ran continuously
for the first 106 seconds, during the second 100 seconds it apparently
paused 5 times. During any of these pauses an indeterminate amount of time
could have passed before the recorder restarted.
If during these 5 pauses the recorder had stopped for a total of 46
seconds, the "hold everything..." transmissions on the two channels would
have coincided with time. We have no data that would allow us to determine
how long the recorder actually stopped. It does not seem unreasonable that
there would have been 46 seconds that Channel II was not being used during
the period that the motorcade was occupied with making the trip to Parkland
Hospital at high speed. In Appendix D, definite evidence is given that the
Channel II recorder made at least one stop of 2.9 seconds duration between
"hold everything..." and "You want Stemmons."
Results
From Table C-1 we see that:
1) On Channel I, "hold everything..." (which coincides in time with
the last of the BBN "shots") occurs 171 seconds before
"you want me... Stemmons".
2) On Channel II, "go to the hospital" occurred 189 seconds before
"you want me... Stemmons", and 64 seconds before "hold
everything..."
OCR for page 66
66
By this analysis, the last of the BRSW "shots" occurred at least 18
seconds after Chief Curry issued his instructions "Go to the hospital" and
the events identified by BRSW/WA could not have been the shots of the
assassination. Except for determining the correction factor for time
measurements in Channel IIA, this result does not require that the two "hold
everything..." transmissions be identical; it requires only that the two
"You want me...Stemmons" transmissions be the same. Note further that
this result is deterministic, not based on probabilistic arguments. If one
includes the known 2.9 second stop of the Channel II recorder discussed
above and in Appendix D, the last of the impulses attributed to shots
occurred at least 20.9 seconds after "Go to the hospital."
For the two "hold eveything..." transmissions to coincide the recorder
would have had to be inactive for 46 seconds, in which case the conjectured
shots would have occurred at least 64 seconds after the chief's
instructions, "Go to the hospital.'" There were five places where the
recorder could have stopped, during which the 46 seconds of inactive time
could have accumulated. For the events identified as shots by BR SW/WA to
have occurred before Chief Curry's instructions, "Go to the hospital," at
least 20.9 seconds would have to be deleted from Channel II, or added to
Channel I. We see no evidence of anything that would allow us to shorten
the Channel II times more than has already been done. Possible mechanisms
that might permit us to lengthen Channel I are backward skips in the
original Dictaphone recording of Channel I, or forward skips on playback.
Backward skips on recording would require manual resetting of the recording
stylus, an unlikely event given the automatic operation of the logging
recorders, and would result in a superposition of recordings as discussed
in Appendix D. Physical examination of the Dictabelt revealed no evidence
of superposed recordings.

C-2. Analysis of Tapes Made Directly from Original Records
After the preceding analysis of the Bowles tape recordings had been
completed, the Committee obtained access to the original Gray Audograph and
Dictaphone recordings from the Department of Justice. These were
transcribed onto tapes carefully so as to keep the amount of 60 Hz hum and
other artifacts added to the tapes to a minimum.
Channel I Recording
The Dictabelt (Channel I) was transcribed using a Dictaphone playback
unit, with its playback speed adjusted to be equal to the original
recording speed. The 60 Hz hum from the original record was used to make
this adjustment. The Dictabelt was in poor condition and it was difficult
to measure accurately the period of the 60 Hz hum required for the speed
adjustment. No skips or repeats were apparent in the process of
transcription, nor are there indications of any on the resulting tapes.
The time between the "You want me... Stemmons" transmission and the "Hold
everything..." transmission, which coincided with the part of the tape
where BRSW/WA said they found shots, was found to be 178 seconds. This
compares with 171 seconds in the analysis of the Bowles tapes, in which we
did not attempt to correct the times to real time.
Channel II Recording
The Gray Audograph disk (Channel II) could not be 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 stylus. However, phonograph turntables operate at a constant rpm,
whereas the Gray equipment maintains a constant linear velocity of the
record relative to the stylus. Moreover, the Gray Audograph records from
the inside out, whereas normal records begin at the outside. Thus, when
the tapes are played back, there is a speed distortion that causes material
at the beginning of the tape (the inside of the record) to be slowed down
(time intervals between events are longer and the frequencies are lower
than those originally recorded) and material at the end of the tape (end of
the record) to be speeded up relative to true speed.
OCR for page 68
68
We were able to use the 60 Hz hum present on the tape to correct for
this speed distortion. The hum level on the original record was fairly
high and is easily discernible in the tapes during the many intervals of
relative silence. By measuring the period of the hum at different points
on the tape, we can determine the correction factor that must be applied to
time measurements to convert them to real time.
The correction factor measurements for many points in the part of the
tape of interest to us are plotted in Figure C-3. Note that in the
interval between "Go to the hospital" at 22 seconds and "You want me...
Stemmons" at 238 seconds the correction factor varies linearly with time.
It has a value of about 0.95 at 130 seconds, the midpoint between these two
events. We can relate the corrected (real) time, to, to the measured
time, tm' by
dtC = Kodtm + K'tmdtm
where Ko is the time correction factor at the midpoint and K' is the
slope of the correction factor line from Figure C-3. If the midpoint is
taken as the time origin and this equation is integrated over the interval
t1Got' to ttYou, tl we obtain
c,You ~ Tc,Go = Ko(Tm,yOu - Tm'Go) + K'(T2m You
m,GO)/2
where Ko = 0.95 and K' the slope of the regression line in Figure C-3 is
0.0005. Sinc 2 2
e the T m,Go = T m,You' given that the time origin is
midway between them, the second term on the right is zero, and
Tc,You - Tc~go = 0~95(Tm~yOu - Tm Go)
Substituting the values for Tm You and Tm Go, we find that
Tc,You - Tc,GO = 206 seconds.

Results
By this analysis Chief Curry instructed the motorcade to go to the
hospital at least 206 seconds before the "You want me... Stemmons't
transmission. The events identified by BRSW/WA as shots occurred 178
seconds before the "You want me...Stemmons" transmission, or at least 28
seconds after Chief Curry instructed the motorcade to "Go to the hospital."
This is a lower bound on the interval, because Channel II was
sound-operated and halted when there were long periods of quiet. This
second analysis confirms the findings from the Bowles tapes that the events
identified by BRSW/WA as shots could not have been the assassination shots.
If one includes the known 2.9 seecond stop of the Channel II recorder that
is discussed in Appendix D, the impulses attributed to shots occurred at
least 30.9 seconds aftr the instruction ttGo to the hospital.It
The two sets of measurements are in reasonable agreement. The two
Channel I times, 171 and 178 seconds (original record), show that the
Bowles tapes played back about 4% faster than real time. If we apply this
same correction factor to the Channel II time obtained from the Bowles
tape, we obtain 197 seconds as the estimate of the elapsed time between "Go
to the hospital" and "You want me...Stemmons". This compares with 206
seconds obtained from the tapes made directly from the original records.
The difference, only 9 seconds, is probably due to the artifacts of the
Bowles tapes: undetected skips, a sequence interpreted incorrectly as a
repeat, or too low an estimate of the gap duration. We tried to be
conservative in correcting for the artifacts on Channel II of the Bowles
tapes and it is not surprising that the time interval between "Go" and
"You" obtained-from the Bowles tape is smaller than that obtained from the
tape of the original recording. The tapes from the original records have
fewer artifacts and a more certain history. They are believed to provide
more accurate estimates of the time intervals than the Bowles tapes.
