Let's get real:   1,000,000 Hz (a MHz).
1 per cent is 0.01 of that, or 10kHz
0.1 per cent is 0.001 of that or 1,000 Hz
0.01 per cent is 0.0001 of 1 MHz or 100 Hz
And 0.001 per cent is the debated 10 Hz!

Now most of the components in ANY radio are not held to tolerances of 0.001
per cent!  Young ears might resolve a 10 Hz difference in tone, but average
ears probably cannot zero beat to even that difference.  Give the frequency
display designers a break, what do you need less than 10 Hz for?   IF you
are off a net by that much, someone will comment on your tone, and you will
talk yourself on.

For those who need the most stable frequency source; an optional TCXO is
available for the Argo V.
