Yes and no. There is a corresponding classical phenomenon with classical wave-packets but neither electrons nor photons are waves and the [tex]\Delta k[/tex] and [tex]\Delta x[/tex] have distinct meanings when you talk about a wave packet and a quantum.The HUP is just the Fourier transform relation that (Delta k)(Delta x)>1/2 for any wave packet. This holds even for a classical light wave of finite extent.

The connection of the HUP with measurement problems was just bad advice given to Heisenberg by Bohr.

What's more the HUP generalizes to more than wave-esque measurements.

It also manifests when say considering spin measurements in different directions.

[tex] \Delta S_z \Delta S_{z'} \ge \frac{1}{2}|[S_z,S_{z'}]| [/tex]

And likewise for

*Any*pair of non-commuting observables.

I know it is conceptually easier to suppose that Heisenberg, Bohr et al "got it wrong" and QM is really a mistaken interpretation of its predecessor, Wave Mechanics. However this is not correct.

If you want to discuss it in detail start a relevant thread and I'll be happy to elaborate.
