 note = {This paper describes the W-60 type atmospheric waveform recorder. The amplifier is aperiodic, covering the frequency range 50 c/s to 80 kc/s, and requires at maximum gain, a signal of 14.5 mV r.m.s. at the input grid to give a half full-scale deflection on a 5" cathode ray tube. (referred to hereafter as c.r. tube.) The time base is triggered by the atmospherics and is variable over the 500 μ sec. to 10 milli-sec. Brilliance modulation of the c.r. spot by a pulse from the time base makes the trace visible only for the duration of the sweep. A camera is employed with the c.r. tube and the exposure are made on perforated 16 mm film. After each exposure, the film is automatically moved on to the next frame, 60 exposures per minute being possible. Provision is made for the synchronization with the c.r. direction finding equipment so that the position of origin of each record may be determined.},
