Ask Dr. SETI ®
I was referred to you by an electrical engineer and amateur radio operator on IRC after asking questions regarding active SETI. The situation is as follows---I recently obtained a 10--18 GHz Rohde & Schwarz signal generator (with AM, FM, and pulse modulation, 1 kHz resolution, and frequency reference input) b/c of its very low price. I initially was planning on opening a terrestrial 3 cm amateur radio beacon transmitter, but the idea of instead opening an active SETI transmitter popped into my mind.
The Doctor Responds:
The technology you propose is relatively trivial, so of course it is practical, and would be easy to implement. However, I should point out to you that the whole question of active SETI remains a politically controversial (and indeed somewhat contentious) subject. On The SETI League website (www.setileague.org) you will find host of articles and guest editorials discussing all sides of the issue of METI (Messaging to Extraterrestrial Intelligence).
