... 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.
From page 61...
... 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 IIB, 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.

... Please APPENDIX C 63 measured time intervals between key transmissions on Channel II and the cummulative time, measured from "hold everything" at which these transmissions occurred, corrected for the speed difference between Channel IIA and Channel IIB.
From page 64...
... 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)
From page 65...
... 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)
From page 66...
... 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.

... Channel II Recording The Gray Audograph disk (Channel II) could not be played on an original Gray playback unit without introducing skips and repeats.

From page 69...
... 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 "Go to the hospital." The two sets of measurements are in reasonable agreement.
