Etherwave pitch calibration drift

Hello,

Every time I tune my theremin and play, after a while (about 10 minutes) the tuning has drifted, expanding the field. To fix, I have to slightly rotate (maybe just move half a mm) the pitch knob to compress the space again.

Any ideas?

Regards,

Jim

Has the theremin warmed up? I give mine 20-30 minutes after I turn it on.

Sorry for getting back so late, I haven't been visiting the forum for months!

I will try letting it "sit" for half an hour before testing again. I will report back.

Thank you

Jim
