Dear Roger, LF Group,
I left the VLF RX set up on your stated frequency today, but no signals have been detected so far. There was a rather curious spectrogram trace close to your stated frequency - see attachment - but I assume this is local QRM, since it repeats every 31Hz or so over the nearby frequency range, and I have seen similar things here before a number of times. 

Cheers, Jim Moritz
