And the ironic thing is that the velocity factor inside waveguide is
*always* greater than one. Really.

Now, with all this talk about velocity factors and the calculation thereof,
one should consider the possibilities of and consequences resulting
therefrom of velocity facors in the range of positive numbers greater than
one.
With these velocity factors, some hams would be able to hear some signals
even before they were transmitted, giving him the time to adjust his rotor,
his antenna tuner, and his hearing before the signal arrives.
If the signal leaves the antenna before its transmitted, then the concern
over impedence matching would be for naught.
