[time-nuts] Mystery Oscillator

Found an old oscillator when cleaning out a barn. It is a model
YH890-1 made by Greenray Industries. Since it is 10 mhz. output, I
though it might be useful for something. It has a BNC connector which
I assume is the output and three terminals on the side. One is chassis
ground. The label says both the input and oven are 28 VDC, so I
suppose putting 28 volts on both terminals is the normal hookup but am
not sure. Does anyone have any incite about this?

Thanks,
Al, retired, mostly
