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.=20

=20
