[time-nuts] FE-5680A software calibration units ?

I’ve designed and built a small power/interface board for my FE-5680A. It takes DC power from a surplus laptop power supply (16-24 VDC) and uses a buck converter to drop that down to 15v and a 5v LDO to supply the 5v pin. It brings the serial and PPS out to a 4 pin SIP header and the 10 MHz to
