my reciever works (Futaba FP-R127DF FM dual conversion) by taking a 
voltage tester to

the 3 contacts designated for the servos. I then manipulated the lever 
on the transmitter

 (Futaba Conquest FP-T4NBF) while keeping an eye out for voltage 
fluctuations on the tester.

 What I discovered was the voltage between the red and black leads held 
a constant 5.28

volts regardless of the signal being recieved. Voltage differences 
between the white lead

was not noticeable. How does the reciever send a signal to the servo if 
not by fluctuating

 voltage? More to the point, how can I "read" this signal?

You are reading the battery voltage between the red and black leads.  As 
for the white lead,

the signal is fluctuating too fast for for a voltmeter, especially an 
analog unit, to respond

 to it.  You will need an oscilloscope to see anything meaningful. Hook 
it ro the white and black

leads.
