Re-submitted Preliminary Model LD-1 Combined Heterodyne Frequency Meter and Crystal Controlled Calibrator Range 100 - 5000 kilocycles for A.C. Operation
Abstract
The re-submitted equipment complies with the requirements of the specifications, ref. (b), in all respects except that the overlap is insufficient in two instances and that the audio output at 350 cycles is slightly low over a very limited portion of the range. However, as previously stated, the audio output is considered quite sufficient for service use. The re-submitted Model LD-1 frequency measuring equipment complies with all provisions of the governing specifications so far as could be determined, and is considered quite suitable for naval use for the purposes intended.
