Jeeez, if we follow the convention of the harmonic being the being written
as FX (and the fundamental F0) where the subscript is some integer which
represents an harmonic and we include 0 as an integer, which is an integer
by definition, then the fundamental or F0 is Fundamental times 0 or O
Hertz, for all frequencies. The first harmonic must then be what we
traditionally call the fundamental. The first harmonic, F1 then is the
Fundamental times 1 and both the fundamental and the first harmonic are the
same.
By way of example. I choose 1 GHz (because it gives me heartburn in
my equipment)
The fundamental F0 = 1 Ghz times 0 = 0 Ghz.
The first harmonic F1 = 1 Ghz times 1 = 1 Ghz
Life sort of gets back to normal as we hit the second fundamental,
but again that depends on which side of the argument which started all of
this, you believe.
The second harmonic F2 = 1 Ghz times 2 = 2 Ghz. Ad infinitum
and ad nausium.
Take care (but don't write back I will be off playing golf in
California for the next week yea wooooo!)

Robert and Scott:
I agree that the fundamental is the First Harmonic.
Now, to muddy things up some more, how does all this discussion
square with calling the fundamental Fo?
