Many radio SETI searches focus on the frequency range where the HI (1.42 GHz) and OH lines (1.6-1.7 GHz) lines are landmarks delineating the water hole This is only a small fraction of the terrestrial microwave window (TMW) from 1-10 GHz. This survey occurs near the center of the TMW at 4.462336275 GHz or pi times the HI frequency. We call this the PiH I (" pie high") survey. The inspiration for PiH I observations comes from Carl Sagan in his book, Contact. This survey builds upon and extends a previous survey at PiH I (Blair, ...
