	Ignorant layman's question here. Does anyone know if any of the previous or

studies have focused on the stars which are within a sphere of space
centered on earth within which
radio signals from the last hundred years (or-so, say starting with Marconi
1903 transmissions) of earth's radio-signals
could be received? I guess it would be all the stars within a 51 light years

Applying such a limit would be more of a PR exercise than good science,
given the low detectability of most leaked signals.  However I believe
all targetted searches limit themselves to around 100 light years, so
are working at that sort of order of magnitude of range.  The general
aim is to cover all plausible stars that are close to us.

The SETI Institute's Project Phoenix is the main targetted radio frequency
search.

As the SETI Institute people and other professionals that frequent 
USENET are normally monitoring only sci.astro.seti of that and this 
group, I have cross-posted the reply.

distance from earth (taking in to account return signal
time.) Just on the off chance someone out there is listening.
