An interesting and thoughtful response. However, it generates a question:

In your train analogy above, what is to keep the leading part of the
echo from being QRMed by the trailing part of the transmitted signal?

BP,

"*" In the 5 Second Time Cycle for the Two Signals; this is
the Two Periods of 'Silence' between the Earth Pulse and
the Lunar Reflection.

EP .= = = = * _ _ _ _ * 5s
LR ._ _ _ _ * -- -- -- -- * 5s

"." Start of the Time Sync for 5 Second Signal Cycle
"=" Earth Pluse Time
"_" Non-Signal Time
"--" Lunar Reflection Time

A 2 Second Earth Pulse with a 2.5 Second Lunar Reflection
Delay creates a One-Half (1/2) Second Period of Silence
between the two Signals.
