autotune command. This will determine the correct osc gain and initial DAC
settings. It will also set t
In my opinion nothing has to be changed. It is working OK this way. To
improve performance it is worth to use linear regulators for the power
supply +12V and -12V that are related to the OCXO supply and EFC.

to measure the GPS time and
