Produces train of accurately spaced pulses. Number of pulses in train is determined by duration of input gate, and distance mark spacing is controlled by values of L1, C2, and R3. R13 is 250 ohms maximum. Output is 0 to 50 v positive, for distance mark spacings of 0.5 to 25 miles in search radar V2 is switched Hartley oscillator, whose output is shaped by mvbr shaper V3-V4, for triggering blocking oscillator VS to produce narrow marker pulses.-NBS, Handbook Preferred Circuits Navy Aeronautical Electronic Equipment, Vol I, Electron Tube Circuits, 1963, PC 55, p 55-2.
