No problem Tim.
I hope someone with knowleadge on matter will give you proper reply.
How do you get frequencies that fall in audio range?
I think that your measuring problem is that your reference (earth magnetic field strenght) is not constant but little changeable during day. This can be key problem of used NMR because the resonance frequency of a particular substance is directly proportional to the strength of the applied magnetic field.
