CHANNEL 2 WAS RECORDED BY THE GRAY AUDOGRAPH.
The Gray Audograph used a AC motor. To control the speed of an AC motor
you control the frequency of the input power. It was used in both Europe
and the US. In the US the main power supply is 60Hz. In Europe it is 50
Hz. The capacity of the same disc's when used in Europe was about 2
minutes longer than when used in the US, because the machine ran slower in
Europe.

As the machine aged, it also slowed down, owing to the aging of its
components. The Audograph used by the Dallas Police Department was
probably 10 years old and could have been 13 years old at the time of the
assassination. How do we know this? Because the DPD purchased the
Audograph in the "early 1950's". We are not talking integrated circuits.
Here is a picture of the electronics for the Gray Audograph.

I have evidence which shows that the hum on the Gray Audograph could not
have been at 60 Hz.

They do not know what the frequency of the hum was for the Audograph.
They never measured it. They assumed it was 60 Hz. It was not 60 Hz.

OK, then what?

Here is an exhibit I made. The purpose of the exhibit is to show the
frequency spectrum for the tape that Robert Berkovitz used in the Court
TV episode. It shows a fundamental frequency of 57 Hertz and a large
amplitude first harmonic at 114 Hz.

This is the tape that some people say is a real-time playback and
matches the FBI tape which was tape speed corrected using a 60 Hz
signal. If that is so, what is causing the 57 Hertz harmonic series?

Here is the exhibit.
The top chart is the entire tape. The middle chart is the frequency
spectrum, showing the 57 Hz and 114 Hz harmonic. The bottom chart shows
the spectogram. The two prominent horizontal lines are the 57 Hz and 114
Hz signals.
