[time-nuts] Re: Spectracom 8143 GPS Disciplined Osc

[paul swed]

Did you do a search online? The manual is readily available.
Should be a useful unit IF you can change the 1.544 MHz to something useful
like 5 or 10 MHz.
Did not look at the schematic to see how they make the 1.544 MHz. Thats a
telco clock frequency.
