Ed,

That's a good point and since it's been over  a dozen years since I read the 
book, it wouldn't surprise me if I forgot or misremembered some important 
part of the story.

Thinking about it now 2 things come into my mind.  Even though radio waves 
travel at the speed of light in free space, there is  a slight slowdown in 
air.  Maybe that doesn't amount to much, but perhaps more importantly, if he 
used short waves it would have required  a number of hops to circle the 
earth.  Each hop should add  some tiny fraction of a second to the total 
time from tx to rx.  Depending on what frequency he used and what layer of 
the ionesphere  it was bouncing off, and how many hops were needed,  that 
may add some time to  the trip.

Anyway, that's my story and I'm sticking to it.

73, Steve KW3A
