- Amateur SETI: Project Bambi
- Searches of the Harvard SETI Group
*With support from NASA and The Planetary Society, Paul Horowitz spent a year as an NRC postdoctoral fellow at Ames Research Center (1981-82), where he and colleagues from Stanford University and NASA built a high-resolution hardware spectrometer that could handle in real time the kind of signal processing that was used in the earlier Arecibo search. Specifically, this "Suitcase SETI" hardware implemented the FFT in firmware, achieving 64K-channel spectrum analysis (0.03 Hz RBW, 2 kHz IBW) simultaneously in each of two polarizations, along with simple baseline/peak searching and archiving. It included a phase-continuous programmable local oscillator for real-time compensation of site Doppler. Here is the block diagram of suitcase seti. Suitcase SETI travelled to Arecibo in March 1982, where it searched 250 candidates (stellar and other), mostly at the second harmonic of HI, at 2.84 GHz. Once again, RFI rejection was impressive; once again, no confirmed signals. However, as a test of the hardware we looked at the maser source W49(OH), producing a spectrum of such detail that, if plotted at 200 dpi, would stretch across the 1000-foot dish. This search was described (with others) in Icarus, 67, 525-539 (1986).*
