[time-nuts] Correcting measured PPS values with receiver sawtooth correction values

[Bob kb8tq]

Hi

One *could* suggest that the manual would be a great source of information for this sort of thing.
The problem there is that pretty much the whole manual talks about the M8 as the target device
once you get into the fine print. The big points have been translated over to the F9P. The fine details
are still cut and paste from the M8. Exactly where the boundary lies between what has been 
corrected and what has not been corrected is very unclear …..

Thus the drill seems to be verify a lot and trust very little …..

The difference between the results of the  two strategies is rather subtle and it is very hard to determine which is the correct one.
