   I  didn't  mean  to  imply  that  one  could  measure  frequency  changes
   instantaneously  . Again , you seem to be confused over the definition of
   "instantaneous " (or "simultaneous") . I'm concerned  about  transmission
   of  information  over  distances where the speed limit c would "normally"
   impose a delay factor no matter what modulation method one used to convey
   the information.  The information itself need  not  be  "instantaneously"
   transferred  in  order  to  "beat"  a  signal traveling at the speed c in
   getting to it's receiver. It just has to get to the receiver  before  the
   normally propogated signal does if the normally propagated signal and the
   FTL signal are "launched" simultaneously.

    Look at it this way : Suppose we want to transmit a  DC  logic  1  state
   that  endures  for  10  microseconds  . If we transmit this signal by the
   usual means over a 300 meter distance , we would expect a  1  microsecond
   delay  before  the  receiver  detected  the  first  positive slope of the
   wavefront. The information (that we have a logic 1 state) still "endures"
   for 10 microseconds (not instantaneous).  But there is a measurable  time
   interval between transmission and reception of the signal. I am concerned
   about  making  THIS  time  interval  zero  ,  not  about  reducing the 10
   microsecond duration of the logic 1 state to nothing (which I don't think
   is possible).

    What  I  mean  by  an instantaneous change in Q is really a SIMULTANEOUS
   change in signal amplitude (as measured across a circuit element  of  the
   transmitter  and a circuit element of the receiver).  This amplitude must
   be measured over at least 1/2 of a period  of  the  carrier  frequency  .
   There  should  be  no  phase shift if the carrier wave is normally out of
   phase (or in phase) with the information wave .

   The  Indianapolis  500  isn't  all that useful either , but at least SOME
   people are impressed by who gets around the track first. I  take  it  you
   would  only  be  impressed  by  "dragstrip" version of a signal race .

   I'll see what I can do to accomodate you, but later .  In the meantime ,I
   think  I can eliminate the possible shortcuts you postulate are available
   to a looping signal path by calculating the attenuation that would  occur
   if the signal had to traverse air. If there's no attenuation then I don't
   think we have a shortcut path.

   Thanks for the input.
