How are the various SETI projects defining what they are

searching for?

Unless one has the parochial idea that only Homo Sapiens

Sapiens (or

smarter) is "intelligent" then clearly the I in SETI is

not that.

In this case simply a non-natural source of RF in a narrow

frequency

range.

The assumption is something in the HSS range of

intelligence range is

required to be the cause of that non-natural source.

Intelligence

meaning outwitting the competition to survival.

So if humans all ascend like Daniel Jackson and spiders

evolve to

making RF mating calls of sufficient amplitude to be

detected at

interstellar distances that will also be non-natural in

the detection

sense of SETI.

The sci-fi idea of "Ascension" might explain why the ETIs
have left the field of action though, and thus also the
Fermi Paradox. I would not be surprised to see many alien
species using electromagnetic communication in the
universe--long-range com will always be limited though by
energy limitations and gas cloud/ atmospheric absorption. A
large number of species on Earth use EM for various reasons
but I haven't heard of any non-human DJs on the air
recently. :)               ...tonyC
