Ask Dr. SETI ®
Is there any way I can convert a satellite TV receiver, down converter, LNA and feedhorn for SETI use? I have quite a bit of equipment just sitting here on my desk. I got all this stuff free with a dish so if I can convert it I'm out nothing. It just seems like I should be able to adapt this equipment for SETI use. Any ideas?
The Doctor Responds:
One very successful 4 GHz SETI system based upon TVRO hardware is Project BAMBI. You may wish to visit their web site for technical details.
By the way, 4 GHz is a great frequency range for continuum radio astronomy (for which you can use a TVRO receiver). In fact, the discovery of the cosmic background radiation was made in this band (by Penzias and Wilson at Bell Labs; work which won them their Nobel Prize. Only don't expect to be able to measure the cosmic background radiation with a satellite TV dish!)
