Hi Jim, what frequency is that, 20.5 kHz? Did you happen to take a screenshot? 73, Markus

While working on VLF receiver noise this morning (~1100 UT) in Arizona a 35dB S/N signal ~ 50Hz wide (somewhat rectangular) appeared on the RJH6x marker for a few minutes, then disappeared. It didn?t appear to be local noise; could it have been RJH6x? It was 20dB over NPM, which makes me think that it couldn?t have been too distant.

73, Jim AA5BW
