[Flexradio] Flex 1500 Frequency stability

I have tried a little experiment. I zero beat WWV @ 10 MHz using the manual (more precise than the automatic system, at least as far as it works for me) offset form in setup. Using the panadapter, you can see when the carrier is centered, and using phase1 you can get the rotation to just

Tim et al. Yes, the link you noted suggests that my findings were similar, about .5 Hz variation. For me, this held even overnight. Very good results I would say. I have to look and see if I have VAC 4.10 or 4.09 as you suggested. I may have to downgrade if I don't make any contacts
