Six of the Convair airframes were given to Raytheon to explore use of velocity-gated continuous wave doppler radar for guided missile target seekers, while most other United States investigators used range-gated pulse radar.

William Duddell

However, Danish physicists Valdemar Poulsen and P. O. Pederson were able to increase the frequency of Duddell's oscillator to the radio range, and in 1902 patented the Poulsen arc radio transmitter, the first transmitter which could generate continuous waves.

The receiver is standard filtered by a 22 pole crystal filter with switchable extra 8 and 6 pole narrow band CW filters, a 14 pole SSB filter and a separate 14 pole CW filter.
