[Yaesu] Proper way of tuning up a analog rig

[Darrell Drake]

We're saying essentially the same thing. I believe Hart wanted the
explanation in "simple" terms !!! :-)  Of course, the beat (from zero)
frequency can be any that is audible.
Any Amateur radios which I've had over the years transmitted a tone of
600-800Hz from a given VFO frequency.
