Most systems mentioned above travel very short distance, so can't reach space
Space or satellite comm x'mit in powerful microwave. The problem is coding method like E^2PRML, etc and modulation like PCM, etc which the alien whether more adv or otherwise may not match ours. The other thing is the signal path, just like a beam of light, did we hit the correct target. So, at the end may be NO comm with them.
Hi I a am a new member of Singastro forum I think it is worth it to send signals to this planet as it might contain aliens.

yah.. i was referring to coding and modulation schemes. :oops: sorry I wasn't clear on that.
