The broadcasts for the Encounter are'nt ordinary electromagnetic leakage.
about a factor 50 more powerful than the nearest competitor (EWBM), and
unlike them they
are narrowband signal stable in frequency and directed on precise sky
for long period of time (3 hours), these factors alone greatly increase
by a HUGE factor compare to ordinary leakage.
They will be send near the galactic plane, in a region where the

is so poor in metal (1/40 solar) and so dynamicaly unstable than no planet
For all practical purpose, this will be our first dedicated interstellar
