I have 2 questions. 1) The displayed time in the SmartSDR window comes from the GPSDO or the computer? 2) If it comes from the GPSDO do you compensate for the IP protocol latency between the computer through the network to the radio and back. I have noticed differences in time between the computer time and the SmartSDR time in the order of .15 to .25 seconds. In the computer I run Dimension 4 time sync app and it is generally within .004 and .008 seconds off.
