I don't see why, you measured it perfectly well with the scope. In fact, I picked that frequency so it would be intuitively easy to read on a scope (pulses exactly 1 square wide at 1ms/div).

A lot of medium to high end DMMs can measure frequency up to a couple of Mhz or so, so it might be worth having a closer look at what you have.

Anyway... that rules out an overall speed problem, your MK14 certainly isn't stuck in third gear.
