[time-nuts] FA-2 Precision Frequency Counter BG7TBL 20190622

[Bob kb8tq]

HI

Assuming 0.01 Hz at 6 GHz is the resolution, that comes out to 1.6 ppt. That’s roughly
10X better than the noise level that Mark reported on the FA1. Given that resolution is not
the same as noise and 10 seconds may well be 10X better than 1 second, it’s not at all clear
how the two data points relate to each other.
