We quickly concluded that the ultimate discrimination between signals reflected from a target, as opposed to noise from the transmitter, should be done finally on the cathode-ray tube. We had to develop the tubes, and then contract with GE and RCA to work together on producing them. I supervised the contracts myself, visiting GE one week and RCA the next, and the following week we would hold a joint meeting at the Rad Lab in Cambridge. I was getting into contract management."
