After moving battery voltage back and forth the oscillator started up. At RF frequency what do you use for shielding to stop interference problems?

Great question and a good way to start the oscillator. I usually physically shake the tablet and this injects noise starting the oscillation. Unfortunately I only have a theoretical input. I have never built a full circuit. I know that mu metal cans are used that cover inductors for shielding purposes. I hope that helps. Thanks for your comment.
