Turn in your results by 1:30 pm the afternoon of the telescope tour.



Rules of the scavenger hunts:

T.3   When was the current L-band wide receiver installed?


T.4   Where do the letters "L" and "S" in L-band and S-band come from?


T.5   What power does the S band radar transmit? How much power does it need in all? At what rate is water pumped through the transmitter to cool it?
