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.
