How are you pulling this signal off ?
Are you plugging into the machine ?
Using a dummy load ?

If there's not much EMI, you can just hook up your scope to an impromptu receiver antenna made from a few loops of wire and place it under Tx coil… that's what I did.
On a second thought, if you have another coil laying around (no matter for which detector, for as long as it doesn't have any onboard logic), you can use it as a receiver too.

Hmm
When I'm feeling better I'll have to give that a try.
Do you auto tune or dial it in ?

My miniDSO sucks at autotuning, so I usually have to spin the dials.
