Results seem to be different for every TCXO. My REF*CAL starts about around .693 and settles to .778 after a couple hours. I borrowed a Rubidium clock from work and got nearly identical results. The only difference was freq source, so the chracteristics must be K3-specific.
Another K3 owner and I ran it on his (#35xx-something) and his started at .717 and settled out at .798. Same basic trends all around. I'm also using the Trimble TB here; it's been active for ~six months and results are always the same. The K3's resolution is still +/- 1 Hz, but now you know your rig uses the right ref osc frequency. The REF*CAL value shown is the compensation for the external freq reference. I'm not sure how Wayne calculates what's shown; maybe he'll publish his secret sauce recipe... 73, matt W6NIA On Sat, 29 Oct 2011 16:38:41 -0500, you wrote: >I just completed the install of my K3EXREF, and am feeding the 10MHZ reference >from a Trimble Thunderbolt. > >After a couple of hours of warm up and settling out my reference osc is >reading 49.379.945.
