Oops, misspoke...

I just realized, toward the end of the episode, I made a hypothetical example of a 3v AC wave going positive for 3v then negative for 3v. I called it "3v peak to peak".

This would of course be 6v, peak to peak.

Looking forward to listening to this one NYBill, have looked at these things numerous times, just don't have a good enough reason to buy one though.
