[time-nuts] A Symmtricom GPSDO Board

I have two similar Symmetricom GPSDO boards
but with a slightly different parts layout
that were manufactured in about 2012. The
OCXO in the first one is 4.1950 Mhz and there
is a 10 Mhz VCO next to it.

The second one has a Symmetricom SA22-c
Rb oscillator. The large blank spot in question
is for the version of these that would have
the Rubidium oscillator and the copper foil
is part of the heat sink for that version.

I haven’t checked the output frequency of
the SA22-c but it is probably the same as
the OCXO version.
