[Lowfer] SAQ in TN

[Chris Waldrup]

I tried and was unsuccessful as well. 
 I live in a very quiet mountain location in middle Tennessee and set up a box loop that I had used for WWVB during the 2017 eclipse. I realized mid day yesterday that I wanted a balanced preamp as I had used a MC1590 circuit in 2017. 
I whipped up a low noise version with an OP27 op amp and tried using my HP 312B selective micro volt meter. No luck, I heard nothing. 
I'll try for a larger loop next year.

That works by increasing the contrast between dark and light areas. It did help as seen in the image at the URL below. What is neat is the wavering freq matches to what I was seeing on their YouTube video as they were fine tuning the transmitter.  73
