Jamming, by natural or deliberate inception is assuredly well-know phenomena,
such solar storms, military broadcasts etc. If one sends an "archived"
message em signals of all types including gammma ray photons could
conceivably blow parts of a sustained message away. Astronomers are now
looking at anomolous intersteller gas-dust clouds as an excellent filter of
many signals, including the possibility of ETI signals. We have just had (for
40 years) the experience of receiving signals, because the testing of sending
signals has not been a technologically achivable option yet :) i.e we have no
large receiveing antena even circling the Oort cloud to confirm how well
signals travel.
For example, look at all the mighty gas giants detected around many of the
nearer stars. We have never been able to receive these signals, as we known
Jupiter is capable of, from interstellar distances. Theoretically if we had
better radio telescopes we might be able to detect such signals buy
electronically screening out the interference, from their parent star. Gas
giants like Jupiter/Saturn/Uranus/Neptune have enough radioactive energy to
put out a whoppingly large broadcast!
As for neutrinos-they penetrate everything, almost. They are therefore
coherent. At least until tachyonic signal is achived. We may have to wait on
that one for a bit.
