It is amazing people will post technical BS in a technical forum such as tubes and sea shells making a great circuit. It brings to mind the quality of teachings from the famous post where we were told that gold DNA produces a substance that coats the metal to fight rust and oxidation.
Actually I did make some tests on the calculator with the first Examiner. When the new Examiner arrives, I will put it and the calculator on the scope to see what signals are there.

Sorry....you brought up the sound frequency/ tube BS and I was just rolling with it. Whatever it takes to find treasure :::shrugs:::
