The clock has its own oscillator that runs from the battery inside your K3S.

I have the K3EXREF and XTCXO3-1 installed on my K3s and have a Jackson Labs LC-XO-Plus GPSDO attached to the factory-installed port. The config setting REF*CAL shows the * to be blinking, indicating data is being received. I tuned into WWV 10MHz and found that my K3s time was pretty far off, based on the audible signal. Using Config:Time, I can adjust the time to match the audible beat. I guess the K3EXREF address frequency but not clock time? I have a separate GPSDO running from ToyNTP http://www.dxatlas.com/ToyNtp/ to keep my PC on time to less than +/- 50 microseconds. There's some high latency somewhere... But digital modes like WSPR have adequately accurate reference time.
