Thanks Bob,
If it helps the switched frequencies are: 0, 10, 20, 40, 60, 80, 100, 120, 140,
160, 180, 190Hz.

Hi
Sounds about right for calibrating / verifying vibrating reed frequency
readouts.

Subject: [time-nuts] US Army Frequency Standard
Hi All,
I recently obtained a curious Low Frequency Standard dating from the late
1950s. Its output can be switched to a number of frequencies from 10 to
190Hz, derived from a tuning fork. It is marked "Signal Corps" and "US Army"
with a type number TS-65D/FMQ-1.
Does anyone have any information about this unit, in particular what it was
used for and why the strange negative going pulse output and specific
frequencies.
Thanks in advance,
John H.
