RE: Schumann frequency - Variation

Posted by pictureguy on May 2, 2015 at 10:22:49:
In my reading 'reviews' of such devices, it is clear that response varies from little to lots.
I'm not going to speculate about WHY you'd want some variability, but I think it isn't a bad idea. But for me? If I had the means, I'd replace the potentiometer with a stepped 1% resistor ladder of custom values so I could TUNE to several frequencies and go back to them with good repeatability.

One company offers to 'mark 7.83hz.' on the tuning dial for a slight additional charge!
My Meter has a frequency input which I may check somehow. Perhaps a tone CD and check at my speaker inputs? I have no idea and dont want to smoke the meter since I DO use the Type-K thermocouple input as a data point for my BBQ Grill.
